Using a Pattern to Predict

3-PS2-2

NameDate

Circle the best answer.

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