Grade 2 Science · World 6: Push & Pull Playground · Level 38
Start and Stop
A force starts something moving or stops it.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 38
- A ball sitting still stays still. It won't move until a force pushes or pulls it.
- Kick it, and the push starts it moving, in the direction of the push.
- A force can stop a moving thing, too. A goalie's hands push against the ball and stop it.
- Rubbing slows things down. A ball rolling on grass slows and stops, because the grass rubs against it.
- Equal pushes or pulls from both sides cancel out. In a tie at tug of war, the rope stays still!
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.
