Circle the best answer.

1.Why roll the car three times on each floor?
  • A.One roll might be unusual, so the results are checked
  • B.Because three is a lucky number
  • C.To wear out the car
2.Your results show the car rolled 90 cm on tile and 30 cm on carpet. What can you conclude?
  • A.The carpet slowed the car more than the tile
  • B.The floors made no difference
  • C.The tile slowed the car more
3.You want to test whether two pushes move a box further than one. What do you change?
  • A.The floor
  • B.The number of pushes
  • C.The box
4.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
5.Before testing, a student says the car will roll furthest on tile. What is that?
  • A.A result
  • B.A prediction to check against the results
  • C.A rule that is always true
6.You want to know whether carpet slows a toy car more than tile. What must stay the same?
  • A.Nothing at all
  • B.The car, the ramp and the height it starts from
  • C.The floor it rolls onto
7.What makes a forces test unfair?
  • A.Changing the push and the floor at the same time
  • B.Repeating the test
  • C.Writing down the results
8.Two equal pushes from opposite sides leave a box still. What should you write down?
  • A.The box was too heavy
  • B.There were no forces
  • C.The forces were balanced, so the box did not move
