Ramp Challenge:

Design a system for a car to drive through a tube and make a U-turn to get from the top of the table to the floor underneath facing the opposite direction.

Write the steps of the design process on paper:
1) define problem
2) brainstorm solutions
3) build and try
4) refine and reflect

Considerations:

• strength and weakness of the materials used.
• does the material or surface erode or change over time?
• how do you use available materials to the best advantage?
