Survive the Stairs

Suggested Materials: Crash test object – a ball of playdough, an action figure with removable parts, light up bouncy ball (any object that visibly, reversibly changes when it crashes into another object) Recyclables Scissors & tape

STEM Concepts: When two objects collide, energy moves between them. Since the stairs are stronger than your design, your design will have to absorb the energy (or shock) and keep your object safe.

Extensions: Can you find any real life examples of shock absorbing systems? What are they made of? 

THE ENGINEERING DESIGN PROCESS

Define the Challenge: Design something that will keep your object safe as it tumbles down the stairs.

Plan Your Design: With the materials you have, what would you like to try? What sorts of materials will help absorb shock?

Create a Prototype: Build your design.

Test Your Creation: Will your crash test object and design make it down the stairs undamaged?

Improve Your Design: How can you make your design even stronger and more shock absorbing? For an extra challenge, limit the number of materials in your design, eliminate tape, or find a safe way to drop your design from way up high.
