Grade 2 Science · World 6: Push & Pull Playground · Level 42
Design a Device
Design a ramp, bumper, or marble run to change speed or direction.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 42
- Engineers design things to solve problems. Today's problem: make a marble change speed or direction.
- To speed it up, make the ramp steeper. To slow it down, make it less steep or add a rough surface, like carpet.
- To change its direction, put a wall or bumper in its path. The wall pushes the marble a new way.
- Engineers follow steps: ask, imagine and plan, build, test, and improve.
- Your turn! Put the steps of designing in order.
- Try it with a grown-up! Build a marble run from paper towel tubes and tape. Can you make the marble turn a corner?
