Circle the best answer.

1.What should you measure to see how much each floor slowed the car?
  • A.The color of the car
  • B.How far the car rolls before it stops
  • C.How loud the car is
2.A car slows and stops on carpet. Which force made it stop?
  • A.No force, it just ran out
  • B.Friction from the carpet, pushing against its motion
  • C.Magnetism
3.Before testing, a student says the car will roll furthest on tile. What is that?
  • A.A rule that is always true
  • B.A result
  • C.A prediction to check against the results
4.You test pushing a box from one side, then from both sides at once. What are you testing?
  • A.What color works best
  • B.How heavy the box is
  • C.How the direction of the forces changes the motion
5.Why roll the car three times on each floor?
  • A.Because three is a lucky number
  • B.To wear out the car
  • C.One roll might be unusual, so the results are checked
6.You want to know if a bigger push makes a ball roll further. How should you push?
  • A.A small push, then a big push, on the same ball and floor
  • B.The same push every time
  • C.A big push on a ball and a small push on a box
7.You want to test whether two pushes move a box further than one. What do you change?
  • A.The number of pushes
  • B.The floor
  • C.The box
8.Your results show the car rolled 90 cm on tile and 30 cm on carpet. What can you conclude?
  • A.The tile slowed the car more
  • B.The floors made no difference
  • C.The carpet slowed the car more than the tile
