Our push test. Each child pushed the same ball from the same line. HOW FAR THE BALL ROLLED Soft push ......... 1 step Medium push ....... 3 steps Hard push ......... 6 steps Same ball, same line, same floor.

  1. 1. What happens when the push is harder?

  • A.So only the push is different
  • B.Because it is the biggest ball
  • C.So nobody loses it
4.Why does every push start from the same line?
  • A.So the steps can be counted from the same place
  • B.So the line stays clean
  • C.So the ball goes faster
5.The hard push went 6 steps and the soft push 1 step. Which was stronger?
  • A.The soft push
  • B.They were the same
  • C.The hard push
6.Who decides how hard each push is in a fair test?
  • A.Nobody, we push any way we like
