Circle the best answer.
1. 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 2. Your four tries give 9, 9, 10, 9. What makes the prediction trustworthy?
A. They are all different B. One try was 10 C. The four tries agree closely with each other 3. A pendulum gives 9, 9, 10, 9 swings in ten seconds. What do you predict next?
A. It cannot be predicted B. About 9 swings C. About 20 swings 4. What would make you stop trusting a motion pattern?
A. Doing more tries B. Results that stop agreeing with each other C. Writing them down 5. Why can a repeated pattern be used to predict?
A. Predictions are guesses B. The same set-up gives about the same result each time C. Patterns are always exact 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 stop swinging C. It will take that time on the next push too 7. One try gives 9 swings. Is that enough to predict?
A. Yes, one is enough B. No, you need a hundred C. No, because one try might be unusual 8. Someone lengthens the string and predicts 9 swings again. What is wrong?
A. Nothing is wrong B. Longer string always means more swings C. The set-up changed, so the old pattern may not hold LessonPrint · 3-PS2-2 · Set 17 · free to copy for classroom use
