Grade 2 Science · World 6: Push & Pull Playground · Level 39
Faster and Slower
A bigger push or pull makes a bigger change in speed.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 39
- The size of a push matters. A gentle kick makes the ball roll slowly. A big kick makes it zoom! Bigger arrows mean bigger pushes.
- Push something the same way it's moving, and it speeds up. That's how you push a friend on a swing higher.
- Push against the way it's moving, and it slows down.
- A class pushed a toy car three ways and measured how far it rolled. The harder the push, the farther it went.
- Try it with a grown-up! Roll a ball gently, then harder. Mark where it stops each time. Which went farther?
Georgia Standards of Excellence in Science:
- S2P2.a — Plan and carry out an investigation to demonstrate how pushing and pulling on an object affects the motion of the object.
