Circle the best answer.
1. 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 2. 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 3. 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. Nothing is wrong C. Longer string always means more swings 4. 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 5. One try gives 9 swings. Is that enough to predict?
A. Yes, one is enough B. No, because one try might be unusual C. No, you need a hundred 6. What would make you stop trusting a motion pattern?
A. Doing more tries B. Writing them down C. Results that stop agreeing with each other 7. A marble takes 3 seconds down a ramp four times running. What do you predict?
A. 6 seconds B. About 3 seconds on the fifth run C. It will not roll 8. 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 LessonPrint · 3-PS2-2 · Set 10 · free to copy for classroom use
