Activity 01
Engineering Challenge: Stop That Marble
Set up a cardboard ramp at a fixed angle. Give each pair four materials (foam pieces, craft sticks, cotton balls, and masking tape) and ask them to build a structure that stops the marble before it reaches a taped line on the floor. After each test, partners discuss what they noticed and must change at least one thing before testing again.
Construct a structure to stop a fast-moving marble.
Facilitation TipDuring Gallery Walk: Design Revision Stories, set clear time limits for each station so students focus on sharing key changes and results.
What to look forProvide students with a picture of a marble rolling towards a target. Ask them to draw one simple structure that could stop the marble and write one word describing the force they used to build it (e.g., push, place).
