Using a Pattern to Predict 3-PS2-2
Name Date
Circle the best answer.
1. One try gives 9 swings. Is that enough to predict?
A. No, because one try might be unusual B. No, you need a hundred C. Yes, one is enough 2. 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 3. What would make you stop trusting a motion pattern?
A. Writing them down B. Results that stop agreeing with each other C. Doing more tries 4. A pendulum gives 9, 9, 10, 9 swings in ten seconds. What do you predict next?
A. About 20 swings B. It cannot be predicted C. About 9 swings 5. 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 6. A swing takes the same time whether pushed hard or gently. What can you predict?
A. A hard push will be quicker B. It will take that time on the next push too C. It will stop swinging 7. A marble takes 3 seconds down a ramp four times running. What do you predict?
A. It will not roll B. 6 seconds C. About 3 seconds on the fifth run 8. 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 LessonPrint · 3-PS2-2 · Set 25 · free to copy for classroom use
