Theme: Drop Day — Save the Water Balloon! Wonder Question: "If you HAD to drop a water balloon from 4 feet up WITHOUT it popping — what would you wrap it in?" Take-home: Inventor's Notebook (kept at camp through Friday) + drop-saver in a brown bag Photo moment: Group "Engineer Salute" — kids hold their balloon-saver overhead with one hand, finger guns at the camera with the other, mouths open in mock-shock

🧠 Learning goals & SEL focus

• Engineering: the Engineering Design Process — ASK, IMAGINE, BUILD, TEST, IMPROVE. The big idea: inventors don't get it right the first time. They iterate.
• Vocabulary in kid words: prototype (your first try — never the final one), iterate (try it, fix it, try again), cushion (something soft that takes the hit instead of the balloon), parachute (a wide thing that catches air and slows the fall)
• SEL: comfort with failure (it's the WHOLE POINT of inventing), patience with a partner during build, courage to drop in front of the group

🛠️ Materials for today (group of 16)

Test payload:

• ~25 small water balloons pre-filled (16 + 9 spares) in a bucket
• 6×8 picnic blanket or tarp for the drop zone
• Sturdy 4-ft drop point (step-stool, table edge, or counselor's extended arm)
• Tape mark on the floor as the "bullseye"

Invention bin (the 5–6 materials kids choose from):

• Cotton balls (1 bag)
• Bubble wrap (cut into 6"×6" sheets)
• Plastic cups (16 oz red Solo-style)
• Drinking straws
• Small plastic grocery bags (parachute option)
• Printer paper (2 sheets per kid)
• Toilet-paper / paper-towel cardboard tubes
• Masking tape + clear packing tape
• Counselor's pre-built balloon-saver as the front-of-room demo

Notebook + co-activity:

• 1 Inventor's Notebook per camper (top-stapled, named on cover)
• Crayons / thin markers + pencils at every station
• 16 extra water balloons for the Water Balloon Toss warm-up
• iPhone in Slow-Motion video mode + counselor low-angle setup OR mini tripod
• Brown paper grocery bags (16 + spares), pre-named

⏰ Schedule

9:00 – 9:15 | Welcome + Wonder Question + Notebook Handout (15 min)

• Counselors greet at the door with high-fives; campers find their assigned seat (pairs set Sunday — same pair all week).
• At each spot: stapled Inventor's Notebook with the camper's name on the cover. NO water balloons at desks yet.
• Counselor hype:

  "Welcome to the GrowFit INVENTORS LAB! This is the week you become a REAL INVENTOR. Today is DROP DAY. Your mission: design something that lets a water balloon SURVIVE A 4-FOOT FALL without popping. Some designs will WORK. Some will… POP. That's the WHOLE POINT. Real inventors POP balloons before they get it right. Are you ready?"

• Wonder Question read-aloud. Take 4–5 kid answers. ("ALL good ideas. Today you get to TRY them.")
• Show counselor's pre-built demo. "By 11:30, every one of you will have built your own. Some will work. Some won't. We're going to film them in SLOW MOTION so you can see EXACTLY what happens."
• Notebook intro (3 min): "This is YOUR Inventor's Notebook. Flip to the COVER. Draw YOURSELF as an inventor. Safety goggles, big smile, holding something you invented. You have 3 minutes."
• Engineer's Pledge (2 min): counselor reads page 1 aloud; every camper signs.
• Safety contract (60 sec): water balloons stay in the bucket until counselor says. Tape goes on the design, not on people. Materials are not food.

9:15 – 9:30 | Warm-up: Water Balloon Toss + 5-Word Crash Course (15 min)

• 8 min — Water Balloon Toss (NO BUILD yet): outside on grass or on the tarp.
  • Pairs 4 feet apart, 1 balloon. Each catch = both kids step back 1. Furthest pair wins a goofy cheer.
  • Counselor seal: "WHY did your balloon pop? The GROUND is hard. Your job today is to make SOMETHING soft so the GROUND doesn't pop the balloon."
• 7 min — the 5 inventor words. Counselor writes BIG on the whiteboard. Kids chorus each:
  • ASK — what's the problem? (Today: balloon vs. ground)
  • IMAGINE — sketch 3 ideas
  • BUILD — pick ONE and make it
  • TEST — does it work? (Most of the time: NO.)
  • IMPROVE — make it better

9:30 – 9:45 | ASK + IMAGINE — Materials Reveal + Sketch 3 Ideas (15 min)

• Materials reveal (5 min): counselor walks invention bin to the front, names each material BIG: "COTTON BALLS! STRAWS! CUPS! BUBBLE WRAP! PLASTIC BAGS! PAPER! CARDBOARD TUBES! TAPE!"
• Pass the bin so every kid touches every material.
• Sketch 3 ideas (10 min): "Open notebook to PAGE 2 — the IMAGINE page. 3 boxes. Sketch 3 different balloon-savers. They don't have to be neat. They don't have to be possible."
• Counselor circulates with cues: "What about a cushion AND a parachute?" "Can you draw one with straws sticking out like crash legs?"
• Younger (6–7): "If 3 is too many, just sketch ONE."
• Older (8–9): "Circle the one you think will work best. Why?"

9:45 – 10:15 | BUILD round 1 — First Prototype (30 min)

• Counselor cue: "Pick ONE of your sketches. Grab the materials you need. BUILD."
• Pair-up + bin rotation in waves of 4 (3 min).
• Build (27 min) — kids work solo at their spot (partners help each other but each builds their own).
• Counselors circulate with FOUR jobs:
  1. No-water-yet rule — water balloons don't come out until 10:30. Kids build around imaginary balloon shape (counselor has 4 dry "demo balloons" to size against).
  2. Stuck-kid SOS — kneel at eye level: "What's your idea? Tell me. Which material first?"
  3. Tape discipline — pre-tear 6" strips at each table.
  4. Halftime call at 10:00: "Step back. Is your design READY to drop? What's missing?"
• At 10:15: "Leave designs at your spot. Snack."

10:15 – 10:30 | Snack + Brain-Break: Pass-the-Compliment + Engineering Charades (15 min)

• Hands washed. Snack at the snack table.
• Pass-the-Compliment (8 min): "I want to compliment Jamie — your design has the COOLEST parachute I've seen."
• Engineering Charades (4 min): counselor calls "BUILDER!" / "DESIGNER!" / "TESTER!" / "IMPROVER!" — kids act each out.

10:30 – 11:00 | TEST round 1 — The First Drop! (30 min)

THIS IS THE MOMENT. Loud, dramatic, video-recorded.

• Setup (5 min): drop zone outside or on the tarp. Counselor with iPhone in slow-mo, low to the ground, framed on the bullseye. Bucket of balloons next to drop point.
• The drop ritual (~1 min per kid × 16 = ~25 min):
  1. Kid walks to the drop point with their design.
  2. Counselor hands them ONE balloon. Kid loads it.
  3. Counselor: "ENGINEERS! READY?" → group: "READY!" → "3 — 2 — 1 — DROP!"
  4. Kid drops. Counselor films. Group reacts.
  5. POP → group does the agreed "OOOOHHHH NOOOO!" arms in the air. (NOT a loss — this is INFORMATION.)
  6. SURVIVE → group does the agreed "OHHHHHH YEAHHHHH!" + high-fives.
  7. Counselor: "What happened? Where did the balloon hit? Great — now you know what to IMPROVE."
• Counselor cue throughout: "POPPING IS GOOD INFORMATION. Real inventors break stuff to learn what to fix."
• The upset kid: squat down. "That's amazing! Now you KNOW what didn't work. Real inventors POP things ALL DAY. Now let's design version 2."

11:00 – 11:25 | IMPROVE + TEST round 2 — Iterate, Retest, Capture (25 min)

• Notebook beat (5 min): "Page 3 — TEST page. Circle POP or SURVIVE. Write 1 sentence WHY. Page 4 — IMPROVE — sketch v2 with ONE change."
• Improve round (10 min): kids return to bin, grab what they need for v2.
• TEST round 2 (10 min): same drop ritual, FASTER. Counselor films again.
• Counselor seal: "Round 1 — most popped. Round 2 — way more survived. THAT is what an INVENTOR does."

11:25 – 11:45 | Slow-Mo Replay Show + Gallery Walk + Photo Moment (20 min)

• Slow-mo replay (8 min): counselor passes the iPhone around the circle (or AirPlays to TV/projector). Kids watch their drops. Big "WHOA"s. Lessons spotted in real time.
• Notebook beat (5 min): "Page 5 — REFLECTION. Draw your favorite drop. Fill in 'I learned that ___.' Counselor seals each page with a star."
• Gallery walk (5 min): kids stand behind their final design. Counselor names 1 cool thing about every kid.
• Photo wall (2 min):
  • Individual: each kid holding balloon-saver at chest level.
  • Group: "ENGINEER SALUTE!" — overhead-hold + finger guns + mock-shock. 3 shots.
• Critical: photograph EVERY design before takedown.

11:45 – 12:00 | Brown Bag Pack-Out + Notebook Storage + Goodbye Cheer (15 min)

• "Bag It" cleanup: SURVIVING balloon-savers go in the kid's named brown bag. POPPED designs — kid's choice to bag or toss. Unused materials back in the bin.
• 2 counselors fold the wet tarp.
• Notebook stays at camp. Stored in named bin.
• Goodbye cheer: "GrowFit Inventors — DIS-MISSED! Tell your parents you POPPED water balloons FOR SCIENCE today. Tomorrow we BUILD BOATS!"
• Photo upload by 12:15 PM — both stills + best 2–3 slow-mo clips.

💬 Counselor tips

• The night before: fill 25 water balloons. Tie tight. Stash in a cooler.
• Pre-build YOUR balloon-saver the night before. Pop a balloon at home to feel the failure first.
• Set up outside if possible. Drops on grass = perfect.
• iPhone slow-mo is the single best engagement tool of the day. Open Camera → swipe to SLO-MO. Frame on the bullseye. Press record BEFORE the kid drops.
• The biggest Monday risk: a kid whose design ALWAYS pops feels like the camp's failing them. Sit at eye level: "Real inventors POP every day. Edison broke 1000 light bulbs before one worked." Help iterate to v2 with ONE specific change.
• Tape rationing. Pre-tear 6" strips at each table.
• The kid whose design SURVIVES round 1. Don't let them switch to a new design — make them IMPROVE round 1 (e.g., "Now drop it from 5 feet!").
• Hot weather check: >85°F = balloons feel GREAT. <60°F data-preserve-html-node="true" = keep drops short + hand towels nearby.

🛟 Safety call-out

• Water balloons are NOT for throwing at people. IN the design or in the drop zone only.
• Drop zone is OFF-LIMITS when someone is dropping. Group watches from 6 feet back.
• Wet floors = slip hazards. Counselor wipes immediately.
• Tape is sticky. Don't tape hair, clothes, skin.
• Materials NOT food. Repeat after snack.
• No scissors today (counselor pre-cuts Sunday).

🎯 Parent take-home — Day 1

Your camper became an INVENTOR today! Today was DROP DAY — designing a contraption that could survive a 4-foot water balloon drop. Your kid learned the 5 magic words of every real inventor: ASK, IMAGINE, BUILD, TEST, IMPROVE. Some designs popped. Some survived. That's the WHOLE POINT. Today's engineering word: PROTOTYPE — your first version is never your last. Ask tonight:

• "Did your water balloon POP or SURVIVE?"
• "If you could redesign it tomorrow, what would you change?"
• "What's the COOLEST thing you saw another kid build?" The contraption in the brown bag (if it came home) is your kid's prototype. They might want to test it at home with water in the sink — let them. Tomorrow: FLOAT DAY — your kid builds a BOAT that has to hold pennies without sinking. Wear clothes that can get a little splashy.

Theme: Float Day — Cargo Boat Challenge Wonder Question: "Real boats are heavy AND made of METAL. How does a giant cruise ship stay on top of the water without sinking?" Take-home: Notebook (still at camp) + boat in a brown bag (let it dry on a paper towel at 11:30 cooldown) Photo moment: Group "Captains Salute" — kids hold their boat at chest level with both hands like presenting cargo to a port master

🧠 Learning goals & SEL focus

• Engineering: the Engineering Design Process — same loop, new problem (buoyancy)
• Vocabulary: float, sink, cargo, buoyancy (the "push up" water gives the boat — kids LOVE this word), hull (the body)
• SEL: patience of slow-adding cargo, team cheering when a friend's boat holds 50+ pennies, graceful "captain's salute" when your boat finally sinks

🛠️ Materials for today (group of 16)

Test setup:

• 1 large water tub (clear plastic ~40-gal storage bin OR kiddie pool OR 2–3 dishpans for parallel tests), ~6" deep
• Old towels (4–5) for splashes + drying boats
• Tarp UNDER the test tub

Cargo:

• ~500 pennies pre-counted into 16 cups of 30 each
• Pile of 200 extra pennies for kids whose boats hold >30
• (Alternative: #10 washers)

Invention bin:

• Aluminum foil (kids tear 12"×18" sheets)
• Plastic cups (16 oz "the hull" base)
• Plastic food storage containers (~6 oz Gladware-style, 1 per kid optional)
• Drinking straws (outriggers, masts)
• Popsicle sticks (deck + rigid hull)
• Plastic wrap (wrapping a frame or sealing a leak)
• Cardboard tubes (sliced lengthwise for a curved hull)
• Paper (mast / sails / labels)
• Duct tape (Gorilla brand) + clear packing tape
• Counselor's pre-built boat with its "max cargo" written on a sign

Notebook + co-activity:

• Each camper's notebook, returned at sign-in, pre-opened to page 6
• 1 simple folded paper boat per kid (counselor pre-folds Sunday) for warm-up
• Race tub for paper boat warm-up (start/finish lines taped on the side) + small fan or mouth-blow
• Brown paper bags + roll of paper towels for drying boats before bagging

⏰ Schedule

9:00 – 9:15 | Welcome + Wonder Question + Notebook Open (15 min)

• Notebooks returned at the door, pre-opened to page 6.
• "Yesterday you saved BALLOONS. Today you build BOATS."
• Counselor hype: "Today is FLOAT DAY. You're going to build a BOAT — a real, working boat — and we're going to find out how much CARGO your boat can hold before it sinks. Penny by penny. Some boats will hold 5 pennies. Some will hold 100. Real engineers design the biggest cargo ships in the world this exact same way."
• Wonder Question read-aloud. Counselor lands the lesson on the whiteboard: "Boats float because they PUSH water out of the way — DISPLACEMENT. The water pushes BACK up. Big and wide = more displacement = more cargo."
• Demo: counselor adds pennies one at a time to ~80% of demo boat's capacity. "Mine held [X] pennies last night."
• Notebook beat (2 min): "Page 6 — see the cargo box? You'll fill in your number at the end. Page 7 — IMAGINE — sketch 3 boats after we warm up."
• Safety contract: water tub OFF-LIMITS until test block. Spills happen — towels are there.

9:15 – 9:30 | Warm-up: Paper Boat Race + 5-Word Refresher (15 min)

• 8 min — Paper Boat Race: 2–4 kids at a time, boats at start line. "BLOW!" → mouth-blow (or fan) to finish. 4–5 heats.
• Counselor seal: "Did anyone's boat get HEAVY when wet? Did it sink? — PAPER absorbs water. Today we're using BETTER materials so the boat STAYS dry."
• 7 min — 5-word refresher at whiteboard. "Yesterday DROP DAY. Today, same 5 words, NEW problem."

9:30 – 9:45 | ASK + IMAGINE — Materials Reveal + Sketch 3 Boats (15 min)

• Materials reveal (5 min): counselor names BIG: "FOIL. PLASTIC CUPS. PLASTIC CONTAINERS. STRAWS. POPSICLE STICKS. PLASTIC WRAP. CARDBOARD TUBES. PAPER. DUCT TAPE."
• Pass the bin so every kid touches each material.
• Counselor cue: "Some materials get HEAVY when wet — PAPER, CARDBOARD. If you USE them, wrap in duct tape or plastic wrap to keep dry."
• Sketch 3 boats (10 min): "Page 7. 3 boats. Different shapes. Flat raft. Deep bowl. Pointy canoe."

9:45 – 10:15 | BUILD round 1 — First Boat Prototype (30 min)

• Bin rotation (3 min) in waves of 4.
• Build (27 min) — counselors circulate with FOUR jobs:
  1. No-water-yet rule — boats do NOT go in the water until TEST block.
  2. Stuck-kid SOS — kneel, name the problem, name the material.
  3. Duct tape discipline — encourage RUNNING a strip along any seam.
  4. Halftime at 10:00: "Step back. Is your boat WATER-TIGHT? Are seams sealed?"

10:15 – 10:30 | Snack + Brain-Break: Pass-the-Compliment + Boat Charades (15 min)

• Hands washed. Snack at snack table.
• Pass-the-Compliment (8 min): "I want to compliment Marcus — your duct tape job is going to keep the water OUT."
• Boat Charades (4 min): "CAPTAIN!" (salute) / "SAILOR!" (row) / "DOCKWORKER!" (load cargo) / "ENGINEER!" (point + pretend-fix).

10:30 – 11:00 | TEST round 1 — Penny by Penny (30 min)

• Setup (3 min): tub at the front (or outside on the tarp). 16 kids in a semicircle, boats in hand, cup of 30 pennies each.
• The cargo ritual (~1.5 min per kid × 16 = ~24 min):
  1. Kid places boat in the water carefully.
  2. Counselor narrates: "Captain [name] is loading the cargo ship!"
  3. Kid loads pennies ONE AT A TIME. Group counts: "1, 2, 3, 4…"
  4. Every 10 pennies, group cheers "TEN! TWENTY! THIRTY!"
  5. Boat tilts → wobbles → sinks. Pennies splash. Group does "GLUB GLUB GLUB!"
  6. Counselor: "Captain [name] — your boat held [X] pennies! CAPTAIN'S SALUTE!"
  7. Counselor scoops pennies (or pre-counts a fresh pile for next kid).
• Counselor cue: "When your boat sinks, count the LAST penny that fit. That's your cargo number."
• Younger kids: counselor adds pennies WITH the kid — don't let a 6-year-old load 50 solo.
• The "I-can-go-higher!" kid: add 10 more from the extra pile. "Captain [name] is up to 50! Up to 60! UP TO 75!" Whole room joins.

11:00 – 11:25 | IMPROVE + TEST round 2 — Iterate, Retest, Capture (25 min)

• Notebook beat (5 min): "Page 8 — TEST. Write round 1 number. Sketch where water came IN. Page 9 — IMPROVE — sketch boat v2."
• Improve round (10 min): kids return to bin. Counselor cue: "INVENTORS change ONE THING per version. If you change 3 things, you don't know which one helped."
• TEST round 2 (10 min): same cargo ritual. Numbers should be HIGHER for most kids.

11:25 – 11:45 | Best-Cargo-Boat Award + Gallery Walk + Photo Moment (20 min)

• Best-Cargo-Boat Award (5 min): counselor announces 3 winners (no losers):
  • 🏆 TOP CARGO — boat that held the most pennies
  • 🛠️ BEST IMPROVEMENT — biggest jump round 1 → round 2
  • 🎨 MOST CREATIVE DESIGN — most unusual shape that still floated
• Notebook beat (5 min): "Page 10 — REFLECTION. 'My boat held [X] pennies. The most improved part was ___.'"
• Gallery walk (5 min): kids behind their boats (still wet on a paper towel).
• Photo wall (5 min): Individual + "CAPTAINS SALUTE!" group. 3 shots.

11:45 – 12:00 | Pat-Dry + Bag It + Notebook Storage + Goodbye Cheer (15 min)

• Pat-dry station: gentle dab on a paper towel.
• Bag It: boat in named brown bag with paper towel inside (catches drips).
• Tub drain: counselor pours water on grass / a drain.
• Notebook stays at camp.
• Goodbye cheer: "GrowFit Inventors — DIS-MISSED! Tell your parents you sailed a cargo ship through a storm! Tomorrow we LAUNCH MARSHMALLOWS!"

💬 Counselor tips

• Pre-build YOUR boat the night before AND water-test it. Aim for one that holds ~40-60 pennies — the "good but not unbeatable" sweet spot.
• Have Gladware-size containers available — they almost always hold the most pennies (water-tight). If a kid grabs one and gets 100+, celebrate the camp record.
• Fill tub to 6" deep. Deeper = harder splash; shallower = boats touch bottom.
• Pre-count pennies into 16 cups of 30 Sunday night. Pile of 200 extras for >30 kids.
• The "my boat won't float" kid: counselor sits with them at the table during snack break + fast-fixes (add cup base, duct tape holes). Round 2 will work.
• Duct tape is the MVP material. Strong brand (Gorilla, 3M). Pre-tear 8" strips.
• The penny-counting is the WHOLE drama. Don't let kids dump pennies. ONE at a time. EVERY kid gets the spotlight for 90 sec.

🛟 Safety call-out

• Water tub OFF-LIMITS until TEST block.
• Wet floors = slip hazards. Wipe immediately.
• Pennies are NOT food.
• Don't drink the test water.
• Duct tape sticks to skin — slow-peel with warm water.
• No scissors today.

🎯 Parent take-home — Day 2

Your camper is now a BOAT BUILDER! Today was FLOAT DAY. Your kid designed and built a boat from foil, plastic cups, popsicle sticks, and duct tape — and tested how many PENNIES it could carry before sinking. They learned BUOYANCY (displacement of water). Today's insight: when round 2 boat held MORE pennies than round 1 — real-life engineering improvement. Ask tonight:

• "How many pennies did your boat hold?"
• "Did your round 2 boat beat your round 1 boat?" The boat in the brown bag: may be damp. Air-dry overnight. Bathtub test at home tomorrow. Tomorrow: LAUNCH DAY — your kid builds a CATAPULT and launches MARSHMALLOWS.

Theme: Launch Day — Marshmallow Catapult Showdown Wonder Question: "If you couldn't WALK to your friend across the room — but you HAD to give them a marshmallow — how would you GET IT to them?" Take-home: Notebook (still at camp) + catapult in a brown bag (travels home very easily — no water) Photo moment: Group "Launch Squad" — every kid frozen mid-fire pose, catapult arm pulled back, marshmallow loaded

🧠 Learning goals & SEL focus

• Engineering: Engineering Design Process — today's twist: iterate for ACCURACY, not just "did it work"
• Vocabulary: catapult, fulcrum (the bendy point — kids LOVE this word), projectile (flying marshmallow), trajectory (the arc), aim
• SEL: patience when rubber bands snap, graceful misses, joy when a friend's marshmallow flies FARTHEST or hits BULLSEYE

🛠️ Materials for today (group of 16)

Ammunition:

• Mini marshmallows (1 bag, 12 oz) OR craft pom-poms (allergy-safe alt — counselor reads roster Sunday + picks)

Invention bin:

• Jumbo popsicle sticks (1 bag ~100, each catapult uses 7–10)
• Rubber bands (1 bag ~50, various widths — the energy source)
• Plastic spoons (1 box of 50 — the "cup" for the marshmallow, bowl-up)
• Plastic bottle caps (jar — optional alt to spoon)
• Clear packing + masking tape
• Index cards / paper for kids to fold mini targets

Target zones:

• 12–15 ft of clear floor (hallway, tarp, gym)
• Distance markers: painter's tape at 3 / 6 / 9 / 12 ft
• 3 target paper plates at 6 / 9 / 12 ft on the floor or wall
• Bonus bullseye: counselor's empty plastic cup on a chair at 8 ft

Notebook + co-activity:

• Each camper's notebook, returned at sign-in, pre-opened to page 11
• Counselor's pre-built catapult at the front
• Brown paper bags for catapults to go home

⏰ Schedule

9:00 – 9:15 | Welcome + Wonder Question + Notebook Open (15 min)

• Notebooks returned, pre-opened to page 11. "Yesterday you built BOATS. Today you build LAUNCHERS."
• Counselor hype: "Today is LAUNCH DAY. You're going to build a CATAPULT — a machine that FIRES marshmallows across the room. Real catapults are how castles got attacked 800 years ago."
• Wonder Question + take answers. Counselor demos: pulls back demo catapult, marshmallow flies across the room. Group gasps. "By 11:30 — every one of you has this."
• Whiteboard mini-lesson (60 sec): arc on whiteboard. "Marshmallow doesn't go STRAIGHT. UP first, then DOWN. That curve = TRAJECTORY. Bend point = FULCRUM. Marshmallow = PROJECTILE."
• Notebook beat (2 min): "Page 11 — IMAGINE. Page 12 — TEST. See the distance ruler? You'll write your FARTHEST shot in feet + BEST AIM out of 3 target tries."
• Safety contract: catapult fires AT TARGETS. NOT at people, ceiling, light fixtures. Anyone firing AT another kid sits out 5 min.

9:15 – 9:30 | Warm-up: Marshmallow Toss + Rubber-Band Crash (15 min)

• 8 min — Marshmallow Toss (no build): pairs 4 ft apart, 5 marshmallows each, underhand toss. Step apart to 6 ft, 10 ft. Marshmallows fly everywhere.
• Counselor seal: "Throwing FARTHER is HARDER. A catapult lets you throw farther WITHOUT a stronger arm. Stored ENERGY does the work."
• 7 min — Rubber-band crash + 5-word refresher: counselor stretches a rubber band off a finger, launches paper across the table. "That's the WHOLE secret. Stored energy → motion."

9:30 – 9:45 | ASK + IMAGINE — Materials Reveal + Sketch (15 min)

• Materials reveal (5 min): "POPSICLE STICKS. RUBBER BANDS. SPOONS. BOTTLE CAPS. TAPE."
• Counselor's "basic catapult" demo (3 min): "There are MANY designs. Here's the simplest one — 7 sticks stacked, 2 stacked separately, rubber bands at both ends. The 'arm' is the 1 stick on top with a spoon taped to the end. You can copy this OR invent your OWN."
• Sketch (7 min): "Page 11. Sketch your catapult. Where's the fulcrum? The spoon? The rubber bands?"

9:45 – 10:15 | BUILD round 1 — First Catapult (30 min)

• Bin rotation (3 min): kids grab popsicle sticks (10), rubber bands (4), 1 spoon, tape.
• Build (27 min) — counselors circulate with FOUR jobs:
  1. Catapult anatomy walk (at minute 5): 5–7 sticks stacked + rubber-banded at one end = the base. 1 stick alone = throwing arm, sitting on top, held by a rubber band at the OPPOSITE end. Spoon tapes to FREE END of arm.
  2. Rubber band guidance — too LOOSE = no power; too TIGHT = snaps. Taut but stretches when pulled.
  3. Spoon attachment — secure or marshmallow flies wrong direction. Counselor checks every catapult before round 1.
  4. Halftime at 10:00: "Test fire DRY (no marshmallow). Does the arm SNAP back?"

10:15 – 10:30 | Snack + Brain-Break: Pass-the-Compliment + Trajectory Game (15 min)

• Hands washed. Snack (no marshmallows yet — those are AMMO, not snack).
• Pass-the-Compliment (8 min): "I want to compliment Lila — your spoon is taped on PERFECTLY straight."
• Trajectory Game (4 min): counselor calls "BASKETBALL!" "ROCKET TO MOON!" "BASEBALL HIT!" "HOSE!" "MARSHMALLOW FROM YOUR CATAPULT!" — kids draw the trajectory in the air with their finger.

10:30 – 11:00 | TEST round 1 — Distance Challenge (30 min)

• Setup (5 min): fire line on the floor. 12–15 ft run zone. Distance markers visible.
• Fire ritual (~90 sec per kid × 16 = ~24 min):
  1. Kid to fire line with catapult.
  2. Counselor hands ONE marshmallow. Kid loads.
  3. Counselor: "INVENTORS! READY?" → group: "READY!" → "3 — 2 — 1 — FIRE!"
  4. Kid PULLS arm back AND LETS GO.
  5. Counselor: "Your shot went [X] feet! GROUP — CHEER!" → "WHOOOOSH!"
  6. Counselor jots on clipboard.
• Counselor cue: "Don't be embarrassed if it goes 1 foot. Round 1 is for FINDING what works."
• "My catapult broke" kid: rubber band snaps OR spoon falls off. Counselor pulls them to a fix-it table for 90 sec, replaces, sends back.

11:00 – 11:25 | IMPROVE + TEST round 2 — Accuracy Round (25 min)

Round 2 is about ACCURACY now.

• Notebook beat (5 min): "Page 12 — TEST. Round 1 distance. Page 13 — IMPROVE. Sketch ONE change."
• Improve round (5 min): add a rubber band? Move spoon? Reinforce base?
• TEST round 2 — accuracy (15 min): 3 paper plates at 6/9/12 ft + bullseye cup at 8 ft.
  • Each kid gets 3 shots in round 2.
  • Bullseye cup = 5 points. Nearest paper plate = 3 points. Farther plates = 1 point.
• Counselor cue: "FAR is one kind of win. ACCURATE is another. Real engineers care about BOTH."

11:25 – 11:45 | 3 Awards + Gallery Walk + Photo Moment (20 min)

• 3 Awards (5 min):
  • 🚀 Distance King/Queen — farthest round 1
  • 🎯 Sharpshooter — most accuracy points round 2
  • 🛠️ Best Improvement — biggest round 1 → round 2 jump
• Notebook beat (5 min): "Page 14 — REFLECTION. 'The trick to my catapult is ___.'"
• Gallery walk (5 min): kids behind catapults. Counselor names 1 cool thing.
• Photo wall (5 min): Individual + "LAUNCH SQUAD!" group (freeze-fire pose). 3 shots.

11:45 – 12:00 | Marshmallow Sweep + Bag It + Notebook Storage + Goodbye Cheer (15 min)

• "Marshmallow Sweep" cleanup. (DO NOT EAT off the floor.)
• Bag It: catapult in named brown bag (counselor's call: tape a "1 extra rubber band + 5 ammo" baggie to it).
• Notebook stays at camp.
• Goodbye cheer: "GrowFit Inventors — DIS-MISSED! Tell your parents you LAUNCHED MARSHMALLOWS today. Tomorrow we BUILD RACE CARS!"

💬 Counselor tips

• Pre-build YOUR catapult night before AND test fire it. Aim for 8–10 feet.
• Wide rubber bands (#64 size) work better than thin — store more energy.
• "My spoon won't stay on" kid: 95% of round 1 failures. Pre-cut 4" duct tape strips for re-taping fast.
• "My rubber band snapped" kid: counselor carries 10+ in a pocket all day.
• "My catapult only goes 6 inches" kid: rubber band too loose / arm too short / base unstable. Counselor fixes ONE.
• Don't let kids stack TWO rubber bands — snaps faster + harder.
• Hot weather = soft marshmallows that squish + don't launch. Cooler if >80°F.
• Pom-pom alternative: check roster. Pom-poms don't squish + are allergy-safe.
• Bullseye cup is the highlight of round 2 — huge deal if anyone lands one. ~1–2 kids/camp manage it.
• Catapults travel home easily — unlike Tuesday's wet boat. Parents see it intact.

🛟 Safety call-out

• NEVER fire AT a person.
• NEVER fire UP (lights, AC vents). Down-zone only.
• Eye protection: not required ages 6–9 but counselor reminds "if launcher fires near your face, close your eyes."
• Rubber bands SNAP. Swap visibly frayed bands before round 2.
• Marshmallows on the floor stay on the floor. Don't eat.

🎯 Parent take-home — Day 3

Your camper became a CATAPULT ENGINEER today! Today was LAUNCH DAY. Your kid built a catapult from popsicle sticks, rubber bands, and a plastic spoon — then launched mini marshmallows for DISTANCE and ACCURACY. They learned about stored energy (the rubber band), the fulcrum (the pivot point), and trajectory (the arc). Insight: real engineering trades distance for accuracy. Long-range catapult misses by a lot. Precision catapult goes shorter but hits target. Same trade-off in: missiles, basketball shots, water hoses, archery. Ask tonight:

• "How far did your marshmallow fly?"
• "Did you hit the bullseye?"
• "What's a TRAJECTORY?" The catapult in the brown bag: ready to use. Take it outside — try a pom-pom or paper. Just NOT at windows. Tomorrow: ROLL DAY — your kid builds a WIND-POWERED RACE CAR and tests it with a fan.

Theme: Roll Day — Wind-Powered Race Car Wonder Question: "How can you make a car GO without a motor, without a battery, and without pushing it?" Take-home: Notebook (still at camp) + race car in a brown bag (dry, lightweight, travels great — bag SAIL-SIDE UP) Photo moment: Group "Pit Crew Pose" — kids on one knee next to their car (like servicing it), thumbs up

🧠 Learning goals & SEL focus

• Engineering: EDP — new variable: AERODYNAMICS + ROLLING FRICTION
• Vocabulary: aerodynamic (smooth shape that air slides over), friction (the "stickiness" between wheel and floor), axle (the rod wheels spin on — must spin FREELY), sail (catches wind), thrust (wind's push)
• SEL: OK-ness of going slowly (some inches, some feet — both are real inventions), patience with sticky axles

🛠️ Materials for today (group of 16)

Wind source:

• 1 box fan on LOW (or 2 small fans / battery blower / hair dryer on COOL)

Race course:

• 8–12 ft smooth runway (gym, classroom tile, hallway, or 12-ft strip of cardboard taped outside)
• Distance markers: painter's tape at 2 / 4 / 6 / 8 / 12 ft
• Start line + finish line clearly taped
• Fan at the start, pointing DOWN the track

Invention bin:

• Cardboard chassis — pre-cut 4"×6" rectangles (2 per kid)
• Plastic bottle caps (4 per kid, pre-drilled centers Sunday)
• Bamboo skewers (2 per kid, snipped to 5" Sunday)
• Drinking straws (2 per kid — AXLE SLEEVES, the magic)
• Paper / cardstock for sails (2 sheets per kid)
• Popsicle sticks (sail masts + reinforcement)
• Clear packing + masking tape

Notebook + co-activity:

• Each camper's notebook, returned at sign-in, pre-opened to page 15
• Counselor's pre-built race car at the front
• Brown paper bags for cars (SAIL-SIDE UP)

⏰ Schedule

9:00 – 9:15 | Welcome + Wonder Question + Notebook Open (15 min)

• Notebooks pre-opened to page 15. "Yesterday you LAUNCHED. Today you ROLL."
• Counselor hype: "Today is ROLL DAY. You're going to build a CAR — no engine, no batteries, no pushing. The WIND powers it. You'll put it on the start line, I'll turn on the FAN, and we'll see how far your car ROLLS."
• Wonder Question + take answers. "WIND!" "Magnets!" "Gravity (hill)!" — "ALL real. Today we use WIND."
• Demo (60 sec): counselor places demo car at start. Turns on fan. Car rolls. "Mine went [X] feet last night."
• Whiteboard mini-lesson (60 sec): car with sail on top. "Wind hits the SAIL = THRUST. Wheels SPIN on AXLES. Spin FREELY = car rolls fast. STUCK = barely moves. That's FRICTION."
• Notebook beat (2 min): "Page 15 — IMAGINE. Page 16 — TEST. Distance + wind direction."
• Safety contract: fan stays in counselor's hands (or on a heavy table). NO kid touches fan blades.

9:15 – 9:30 | Warm-up: Wind Tag + Aerodynamics Crash (15 min)

• 8 min — "Wind Tag" with paper airplanes (no cars yet): counselor demos one fold style. Kids run in 15×15 area on "WIND!" → freeze on "FREEZE!" Counselor asks 2 kids "Why does YOUR airplane fly farther?"
• Counselor seal: "The SHAPE of the airplane changed how far it flew. Today, the SHAPE of your CAR will change how far IT goes. That's AERODYNAMICS."
• 7 min — 5-word refresher + 3 new words: "AXLE. SAIL. THRUST."

9:30 – 9:45 | ASK + IMAGINE — Materials Reveal + Sketch (15 min)

• Materials reveal (5 min): "CARDBOARD CHASSIS. BOTTLE CAP WHEELS. SKEWER AXLES. STRAW SLEEVES. PAPER SAILS. POPSICLE MASTS. TAPE."
• The magic part (3 min): counselor holds a chassis with 2 straws taped underneath + skewer through. "The skewer SPINS FREELY inside the straw. Wheels on skewer ends. Wind pushes → wheels SPIN. If you tape wheels DIRECTLY to chassis = STUCK = slow car."
• Sketch (7 min): "Page 15. Where are wheels? Sail? Big sail or small sail?"

9:45 – 10:15 | BUILD round 1 — First Race Car (30 min)

• Bin rotation (3 min): 1 chassis, 4 wheels, 2 axles, 2 straws, 1 paper, 2 popsicle sticks, tape.
• Build (27 min) — SECRET STEP is the axle. Counselor walks every table at minute 5:
  • "Tape STRAW underneath chassis — front + back."
  • "Slide SKEWER through straw — straw = tunnel. Skewer SPINS inside."
  • "Push WHEEL onto each end. WHEELS SPIN."
  • "Now SAIL. Tape popsicle stick UP. Tape paper to popsicle stick. SAIL."
• Counselors circulate FOUR jobs:
  1. Axle check at minute 15 — MOST COMMON failure: wheels too tight = won't spin. Counselor wiggles each kid's wheels. If stuck, removes + reapplies looser.
  2. Sail attachment — extra tape at base of mast.
  3. Stuck-kid SOS.
  4. Halftime at 10:00: "Roll your car GENTLY on the table — do wheels spin freely? If no — fix it now."

10:15 – 10:30 | Snack + Brain-Break: Pass-the-Compliment + Sail Charades (15 min)

• Hands washed.
• Pass-the-Compliment (8 min): "I want to compliment Jamie — your axles spin SO smoothly."
• Sail Charades (4 min): "SAILBOAT SAIL!" (arms wide) / "WIND TURBINE!" (spin) / "FLAG!" (flap loose) / "AIRPLANE WING!" (straight).

10:30 – 11:00 | TEST round 1 — First Race (30 min)

• Setup (5 min): course on floor. Fan at start. 16 kids line up.
• Race ritual (~1.5 min per kid × 16 = ~24 min):
  1. Kid to start line. Places car on start mark. Counselor positions fan at sail.
  2. "INVENTORS! READY?" → "READY!" → "3 — 2 — 1 — WIND!" Counselor turns fan ON.
  3. Car ROLLS. (A lot. 2 inches. Sideways. Tips. Sometimes all of the above.)
  4. Counselor counts 10 sec OR until car stops. Fan OFF.
  5. Counselor measures: "Inventor [name]'s car went [X] feet! GROUP — VROOM!" → "VROOOOM!"
• Counselor cue: "Doesn't matter if FAR or NOT. Round 1 tells you WHAT to IMPROVE."
• Common round 1 failures (counselor names + fixes):
  • Wheels won't spin → axle too tight
  • Car flips → sail too big / top-heavy
  • Car goes SIDEWAYS → sail tilted / wheels misaligned
  • Car barely moves → sail too small

11:00 – 11:25 | IMPROVE + TEST round 2 — Iterate, Retest (25 min)

• Notebook beat (5 min): "Page 16 — TEST. Page 17 — IMPROVE. Sketch ONE change."
• Improve round (10 min): counselor cue: "ONE change. Bigger sail OR looser wheels — not both."
• TEST round 2 (10 min): distances INCREASE for most.

11:25 – 11:45 | PIT CREW Race Brackets + Gallery Walk + Photo Moment (20 min)

The FUN finale.

• Bracket setup (3 min): counselor pairs cars head-to-head — 8 races of 2 cars side by side. Whichever goes FARTHER in 10 sec wins.
• Race rounds (10 min):
  • Round 1 — 8 races (16 → 8)
  • Round 2 — 4 races (8 → 4)
  • Round 3 — 2 races (4 → 2)
  • Final — CHAMPIONSHIP
  • Counselor narrates like a sportscaster.
• Awards (3 min):
  • 🏎️ Champion — bracket winner
  • 🌪️ Most Improved — biggest round 1 → 2 jump
  • 🎨 Coolest Design — most creative-looking
• Notebook beat (3 min): "Page 18 — REFLECTION. 'The trick to my car is ___.'"
• Gallery walk (1 min): quick — cars overhead in a line.
• Photo wall (5 min): Individual + "PIT CREW POSE!" group (one knee, thumbs up, car next to). 3 shots.

11:45 – 12:00 | Bag It + Notebook Storage + Goodbye Cheer (15 min)

• Bag It: car in named bag SAIL-UP.
• Notebook stays at camp.
• Goodbye cheer: "GrowFit Inventors — DIS-MISSED! Tell your parents you BUILT A WIND-POWERED RACE CAR! Tomorrow is the BIG DAY — RUBE GOLDBERG TEAM CHALLENGE and your PARENTS COME!"

💬 Counselor tips

• Pre-build YOUR car night before AND fan-test it. Aim for 6–8 feet — kids will exceed.
• Pre-drill bottle caps Sunday. Tiny nail or push pin, centered.
• Pre-snip skewers to 5" Sunday.
• Box fan on LOW. High blows cars off track.
• "My wheels won't spin" kid: 90% of round 1 issues. Loosen wheel-skewer fit OR push slightly larger nail through cap hole.
• "My car keeps flipping" kid: sail too tall/big. Shorten mast or trim sail.
• "My car goes SIDEWAYS" kid: wheels misaligned. Adjust straw positions.
• The bracket race is the day's HIGHLIGHT. Don't skip. Lean into sportscaster energy. Slow cars also get a whole-camp cheer.
• Sail crush in bag: bag SAIL-SIDE UP gently. Tell parents "sail might need re-taping at home."

🛟 Safety call-out

• NEVER touch fan blades. Counselor controls fan.
• Skewers are pointy. Counselor pre-snips Sunday + hands out replacements.
• Race zone is a no-foot zone — kids 6 ft back, no stepping on cars.
• Bottle caps NOT food.
• Fan cord taped down (trip hazard).

🎯 Parent take-home — Day 4

Your camper became a CAR ENGINEER today! Today was ROLL DAY. Your kid built a WIND-POWERED race car from cardboard, bottle caps, skewers, straws, and paper. They learned about AXLES (so wheels spin freely), SAILS (catching wind), and AERODYNAMICS (how shape affects speed). Insight: BIGGER ISN'T ALWAYS BETTER. Bigger sail catches more wind but also weighs more + tips the car. Real engineers tune the trade-off. Ask tonight:

• "How far did your car go in round 2?"
• "What's an AXLE?"
• "Did your car win the bracket race?" The car in the brown bag: dry + ready. House fan on LOW works perfect. Or a hair dryer on COOL. TOMORROW IS THE BIG DAY — RUBE GOLDBERG TEAM CHALLENGE! Please arrive 5 minutes early at PICKUP (11:55 AM). Your kid will demo their team's chain-reaction invention LIVE for you, then receive their CERTIFIED INVENTOR award + completed Inventor's Notebook.

Theme: Chain Day — Rube Goldberg Team Showcase Wonder Question: "What if you HAD to ring a bell — but you weren't allowed to TOUCH the bell? What's the most RIDICULOUS way you could ring it?" Take-home: Completed Inventor's Notebook with counselor-signed "Certified Inventor" certificate on the back cover + the kid's Rube Goldberg component piece in the brown bag Photo moment: Group "Inventors Squad" — safety-goggles pose (hands cupped around eyes), whole team huddled around their working Rube Goldberg machine, with families behind

⚠️ Friday is different — counselor PREP is heavier

Today has a parent-facing showcase at 11:55. Counselor needs to be set up early. Read this whole day file before 8:45 AM. Rube Goldberg team builds take longer than any other day's project — protect the 90-min build window from 9:30 to 11:00.

🧠 Learning goals & SEL focus

• Engineering: synthesis — DROPS + FLOATS + LAUNCHES + ROLLS combined into one CHAIN REACTION machine
• Vocabulary: Rube Goldberg (a deliberately complicated machine that does a simple job — invented 100 years ago by a cartoonist), chain reaction, trigger, step, cascading failure (when one step fails the whole chain stops — HILARIOUS to fix)
• SEL: teamwork (all in teams of 4), persistence (chains fail a lot — that's the bit), performing for parents at 11:55, pride at week's end

🛠️ Materials for today (group of 16, in 4 teams of 4)

Re-use ALL of the week's invention bin — cardboard, popsicle sticks, rubber bands, paper, cups, straws, tape, bottle caps, skewers, plastic spoons, marshmallows/pom-poms (plenty left from Mon–Thu). Plus cars + catapults from Wed/Thu may be reused as chain elements.

New for Friday (the chain triggers + endings):

• 🎱 Marbles (1 bag of ~30 large — most common rolling trigger)
• 🔔 1 small bell OR hand-held xylophone OR kazoo — the FINAL output of EVERY team's chain
• 🥡 Cardboard tubes (saved up — RAMPS that marbles roll down)
• 🧱 Books or wooden blocks — prop ramps at different heights
• 🪜 Cardboard "dominoes" — pre-cut 30+ rectangles ~2"×3" Sunday
• 💧 Small cup of water + empty cup (optional water element)
• 🎈 A few small NON-water balloons (rubber band snaps balloon → balloon pops → starts the chain)
• 📐 Extra painter's tape rolls

Notebook (last day — goes HOME today):

• Each camper's notebook, returned at sign-in, pre-opened to page 19
• One Sharpie per counselor for signing back-cover certificate

Showcase setup:

• 4 "build zones" on the floor — each team gets ~6×8 ft, marked with painter's tape
• "Welcome Families!" sign at the door
• The "Engineer's Pledge of Honor" poster at the front (printed Sunday)
• 1 named brown paper bag per camper (stacked at door from Sunday) — fits the notebook

⏰ Schedule

9:00 – 9:15 | Welcome + Wonder Question + Team Reveal + Notebook Open (15 min)

• HIGH energy — this is the HIGHLIGHT day. Counselors greet at the door with names.
• Today seats are reorganized into 4 TEAM TABLES (counselor pre-decided Thursday night — balance personality / skill / energy mix). At each spot: notebook pre-opened to page 19.
• "Welcome to FRIDAY. Last day. Today YOU work in teams of 4. Today YOU build the most RIDICULOUS machine ever. Today your PARENTS come at 11:55 to SEE IT WORK."
• Counselor hype:

  "All week you invented SOLO. Today you invent TOGETHER. We're going to build RUBE GOLDBERG machines — a complicated chain reaction that does a SIMPLE thing. Like ringing this bell. (holds up bell) The job is RING THE BELL. But the chain reaction to GET there has to have 5 STEPS. Marble rolls down ramp → knocks dominoes → dominoes tip catapult → catapult launches marshmallow → marshmallow hits bell."

• Wonder Question + take 4–5 wild answers.
• Team reveal (2 min): counselor calls teams ("Team Earthquake," "Team Whirlwind," "Team Marble Mayhem," "Team Cartoon Chaos"). Kids whoop.
• Notebook beat (1 min): "Page 19 — TEAM SECTION. Write team name + 3 teammates. Page 20 — favorite invention from the week."
• Safety contract: "Today you SHARE materials. NOBODY hoards. NOBODY stops cooperating."

9:15 – 9:30 | Warm-up: "Group Chain" Body Game + 5-Word Refresher (15 min)

• 8 min — Group Chain: team line side-by-side. Counselor calls "READY, GO!" — kid 1 claps → kid 2 jumps → kid 3 spins → kid 4 bows. One chain. Build complexity over 4–5 rounds. Cheers when whole chain runs in 5 sec.
• Counselor seal: "THAT was a chain reaction. Today you build a MACHINE that does the same thing."
• 7 min — 5-word refresher + new word: "RUBE GOLDBERG. ROOB GOLD-BERG. His real name was Reuben Goldberg. Drew cartoons of crazy machines 100 years ago. Today YOU build the real thing."

9:30 – 11:00 | ASK + IMAGINE + BUILD + TEST + IMPROVE — Team Build (90 min)

ONE GIANT block of build-test-iterate.

9:30 – 9:45 | Team Brainstorm (15 min):

• Each team sketches 5 boxes (5 steps): "What's step 1? Step 2? Step 5?"
• Counselor walks the room. Common gravitations:
  • Marble rolls down ramp (step 1)
  • Marble hits dominoes (step 2)
  • Last domino tips catapult (step 3)
  • Catapult launches marshmallow (step 4)
  • Marshmallow hits bell (step 5) — DING!
• Counselor approves each team's plan with a thumbs-up.
• Younger kids: counselor offers ONE step.

9:45 – 10:15 | Build round 1 (30 min):

• Teams collect materials (re-stocked Thursday night). Cars + catapults from earlier in week are FAIR GAME.
• Counselors circulate FOUR jobs:
  1. Team referee — all 4 kids contributing. Silent kid? Assign job: "you're in charge of the dominos line."
  2. Tape supply — Rube Goldberg = MASSIVE consumption. Pre-tear 8" strips.
  3. "Marble rolling off ramp" — most common physical problem. Painter's tape "walls" on ramp edges.
  4. Step-spacing — kids put steps TOO FAR APART. "If marble has to travel 4 feet between steps — TOO FAR. Make it 12 inches."

10:15 – 10:30 | Snack + Brain-Break: Pass-the-Compliment + Showcase Pep Talk (15 min):

• Hands washed. Snack at snack table.
• Pass-the-Compliment (5 min): today's twist — kids compliment a TEAMMATE. "I want to compliment Marcus — your team is using YOUR cone-tube ramp idea."
• Showcase Pep Talk (5 min): "In about 2 hours your PARENTS will be standing right HERE. They'll WATCH you DEMO. Some chains work FIRST try. Some need 2–3 tries. That's NORMAL. Real engineers RESET ALL the time."

10:30 – 11:00 | Build round 2 — TEST + IMPROVE (30 min):

• Teams test the full chain. Most FAIL on first run — step misses, marble rolls off, domino doesn't tip.
• THIS IS THE WHOLE POINT. Counselor narrates: "STEP 1 worked! STEP 2 worked! STEP 3 — UH OH! What happened? Fix it — run it again."
• 5–10 test runs typical before whole chain works end-to-end.
• Counselor cue: "Real Rube Goldberg engineers run machines 50 TIMES before showing on TV. You're going to run yours 3–5 times."
• By 11:00: every team has a chain that works AT LEAST ONCE end-to-end. Struggling team? Counselor SIMPLIFIES (cut from 5 steps to 4) so they have a working machine for parents.

11:00 – 11:25 | Final Polish + Slow-Mo Capture + Notebook Beat (25 min)

Dress rehearsal.

• Each team runs chain 3 times in a row (15 min):
  • Run 1: test, fix issues.
  • Run 2: counselor films in slow-motion on iPhone.
  • Run 3: the "this is the version we show parents" run.
• Notebook beat (5 min) — capture the week: "Page 20 — FAVORITE INVENTION. Sketch + 'I am proudest of ___.' Page 21 — 3 INVENTORS I admire. Page 22 — ONE thing I want to INVENT next."
• Counselor seals each kid's page with a star.
• At 11:23 (2 min before family prep): counselor closes each notebook. Stack: Mon → Tue → Wed → Thu → Fri → Pledge → Reflection → Certificate.
• Counselor signs back-cover "Certified Inventor" certificate — walk to each kid with Sharpie. Open back cover. Write camper name + week-of date. Sign on counselor line. Make eye contact, shake their hand, say: "You are a Certified GrowFit Inventor. Congratulations." 30 sec each. All 16 in 8 min.
• Brown bag staging: counselors stage named bags at each seat with notebook + parent take-home card inside.

11:25 – 11:40 | Photo Warm-Up + Showcase Pre-Brief (15 min)

• Showcase Brief (5 min): "In 15 min your parents walk through that door. You and your team will demo your machine ONCE — and we'll do it big. PRACTICE saying 'Mom / Dad / [name], watch THIS!' before you start. Be LOUD. Be PROUD."
• Practice run (5 min): each team does ONE practice demo, whole camp cheers EVERY team.
• Kids-only group photo (5 min): "INVENTORS SQUAD!" safety-goggles pose. 3 shots.
• At 11:38: counselor walks to gate to greet arriving parents. Direct to "viewing area" 6 ft from each build zone.

11:40 – 11:55 | Parent Arrival + Settle-In (15 min)

• Parents arrive (sign asked for 11:55, some early). Warm greetings: "Thanks for coming! 4-team chain reaction showcase. Each team demos once."
• At 11:53, counselor calls all kids to sit in front of build zones. "Kids — eyes up. Parents — please hold applause until each team finishes the full chain so we can hear if the bell rings!"

11:55 – 12:00 | THE SHOWCASE + Certificate Reveal + Goodbye (final 5 min)

This is the MOMENT. Tight, joyful, real.

• Team demos (~3 min total): each team performs ONE chain run.

  "First up — TEAM EARTHQUAKE! Their machine has 5 steps. Their job: RING the bell. Team Earthquake — go!"

• Team starts. Parents watch. Some chains work perfectly. Some fail — counselor laughs + "INVENTOR LIFE! Reset and try again!" Each team gets ONE try (or 2 if first fails).
• Certificate Reveal + Group Photo (~1 min): "ALL OF YOU — open your notebook to the BACK COVER!" "Signed by your counselors. You are now CERTIFIED INVENTORS of GrowFit." Parents applaud. Final group photo "INVENTORS SQUAD!" with families behind.
• Goodbye Cheer (~30 sec): all together — "ASK! IMAGINE! BUILD! TEST! IMPROVE!" three times, loud.
• Final goodbye (~30 sec): "Thanks for an AMAZING week. Each kid takes their notebook home. See you next session!" Counselor releases each kid to confirmed parent.

📦 Post-camp counselor wrap-up (12:00–12:30)

• Build zones cleared. Salvageable materials back to invention bin.
• Storage bin: empty (all notebooks went home).
• Tarp, fan, water tub returned to storage.
• Photo upload: all individual + team + Rube Goldberg slow-mo clips uploaded to parent socials folder by 12:30 PM.
• Russ debrief note (5 min): what worked / didn't, any kid/parent flags, equipment damage, restock needed.

💬 Counselor tips

• Friday morning prep IS THE DAY. If notebooks aren't pre-prepped + brown bags labeled before 9 AM, scrambling.
• Team-pick matters more than any other day. Pre-decide Thursday night. Don't put 4 quiet kids together. Don't put 4 loud kids together. Mix.
• "My team chain doesn't work" anxiety: at 10:45 if a team hasn't worked end-to-end ONCE, counselor SIMPLIFIES. Cut steps 4 + 5 → bell rings off step 3. Working 3-step > broken 5-step.
• The showcase WILL have a chain fail in front of parents. Lean into it: "INVENTORS RESET ALL THE TIME!" Reset, run again. Parents LOVE the second try.
• DON'T let the showcase go long. 4 teams × 45 sec each = 3 min. If chain fails 3 times in a row, counselor takes over: "Team Earthquake — let's run STEPS 1-2 only as the highlight. THERE — bell! GROUP — cheer!"
• The certificate hand-out is the most-remembered moment of the WEEK. Real eye contact, real handshake, real sentence: "You are a Certified GrowFit Inventor."
• Slow-mo of chain reactions = parent-social GOLD.
• "I want to take a chain piece home" kid: every kid wants the marbles. ONLY let kids take their OWN built piece. Marbles + bell stay at camp.

🛟 Safety call-out

• Water + sunscreen (any outdoor build elements).
• Marbles are CHOKING HAZARDS for younger kids. Counselor counts marbles in + out. None in pockets.
• Balloons (popping kind) — counselor inflates + ties. Kids don't blow up (choking risk).
• Bell + xylophone are LOUD. Monitor noise.
• Parents arrive at 11:55 — space CLEAR of stray materials.
• Confirm pickup adult for each kid at the gate.

🎯 Parent take-home — Day 5 (inside the brown bag, with the notebook)

CONGRATS — your camper just graduated from GrowFit Inventors Camp! OPEN THE NOTEBOOK FIRST. Inside is every sketch, prediction, and reflection they made this week. Flip through it together. Ask about a specific page. That's the conversation. The week in review:

• Monday — DROP DAY: designed a water-balloon-saver
• Tuesday — FLOAT DAY: built a boat that held [X] pennies
• Wednesday — LAUNCH DAY: built a catapult, fired marshmallows for distance + accuracy
• Thursday — ROLL DAY: built a wind-powered race car, tuned axles + sails
• Friday — CHAIN DAY: worked in a team of 4 to build a RUBE GOLDBERG chain reaction, demoed LIVE for you Why no fancy stuff came home: the camp uses simple materials on purpose. Cardboard. Tape. Bottle caps. Real engineers prototype with what's around them. Edison started with junk. The 5 magic words your camper now knows: ASK what the problem is. IMAGINE 3 solutions. BUILD the one you like best. TEST if it works. IMPROVE what didn't. Same 5 words apply to: homework, fixing the LEGO® that broke, planning a birthday party, designing a fort. Real life. What to do at home:
• Frame the notebook (or pin the favorite page to the fridge)
• Pick ONE invention from the week to recreate this weekend (the catapult is the easiest at-home redo — popsicle sticks + rubber band + spoon)
• Watch a Rube Goldberg video together on YouTube (search "OK Go This Too Shall Pass") The contraption / chain piece in the brown bag: keep it. Display it. Recreate it. Sign up for next session at growfitcamp.com!

Inventors Camp is mostly consumable (each contraption goes home daily). This is the master reference for what to grab from the storage closet Sunday + what to reorder.
