Marshmallow Tower Challenge

Innovation Hour

Materials Needed (per 10 campers):

  • Marshmallows (regular-sized and/or mini marshmallows)

  • Toothpicks

  • Measuring tape or ruler

  • Timer

  • Paper and pencils (optional for sketching initial ideas)

Objective: Campers will collaboratively build tall and creative structures using marshmallows and toothpicks, developing teamwork, communication, problem-solving, and engineering skills.

Step-by-Step Instructions:

1. Introduction (5 minutes)

  • Introduce the challenge by explaining the goal: building the tallest or most creative freestanding structure possible using only provided materials.

  • Briefly discuss basic structural principles such as balance, stability, and support.

2. Demonstration & Planning (5 minutes)

  • Demonstrate how to safely connect toothpicks and marshmallows.

  • Allow teams a few minutes to discuss and sketch their design ideas.

3. Building Challenge (25 minutes)

  • Distribute materials equally and start the timer.

  • Teams collaborate to build their marshmallow towers.

  • Counselors circulate to encourage teamwork, offer advice, and facilitate creative problem-solving.

4. Measuring and Sharing (10 minutes)

  • After time expires, each team measures and records their structure's height.

  • Teams present their structures, explaining their design approach and reflecting on challenges and successes.

5. Clean Up (5 minutes)

  • Collect unused materials.

  • Dispose of used marshmallows and broken toothpicks.

  • Ensure workspace is tidy.

Assessment:

  • Observe camper teamwork, creativity, and problem-solving skills.

  • Facilitate a discussion reflecting on what strategies worked best and lessons learned from the activity.
