Using a Pattern to Predict

3-PS2-2

NameDate

Circle the best answer.

1.A swing takes the same time whether pushed hard or gently. What can you predict?
  • A.It will take that time on the next push too
  • B.A hard push will be quicker
  • C.It will stop swinging
2.A marble takes 3 seconds down a ramp four times running. What do you predict?
  • A.About 3 seconds on the fifth run
  • B.6 seconds
  • C.It will not roll
3.Someone lengthens the string and predicts 9 swings again. What is wrong?
  • A.Longer string always means more swings
  • B.Nothing is wrong
  • C.The set-up changed, so the old pattern may not hold
4.A pendulum gives 9, 9, 10, 9 swings in ten seconds. What do you predict next?
  • A.It cannot be predicted
  • B.About 20 swings
  • C.About 9 swings
5.Why can a repeated pattern be used to predict?
  • A.Predictions are guesses
  • B.Patterns are always exact
  • C.The same set-up gives about the same result each time
6.Your four tries give 9, 9, 10, 9. What makes the prediction trustworthy?
  • A.One try was 10
  • B.The four tries agree closely with each other
  • C.They are all different
7.One try gives 9 swings. Is that enough to predict?
  • A.No, you need a hundred
  • B.No, because one try might be unusual
  • C.Yes, one is enough
8.What would make you stop trusting a motion pattern?
  • A.Writing them down
  • B.Doing more tries
  • C.Results that stop agreeing with each other
