Circle the best answer.
1. 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 2. 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 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. It cannot be predicted B. About 20 swings C. About 9 swings 5. 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 6. 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 7. A marble takes 3 seconds down a ramp four times running. What do you predict?
A. 6 seconds B. It will not roll C. About 3 seconds on the fifth run 8. 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 LessonPrint · 3-PS2-2 · Set 9 · free to copy for classroom use
