3-PS2-2: Use motion patterns to predict.

Official text

Make observations and/or measurements of an object's motion to provide evidence that a pattern can be used to predict future motion.

What it means for your child

Your child observes and measures motion that repeats, like a pendulum or a bouncing ball, and uses the pattern to predict what happens next.

Try it at home

1. Tie a washer to a string to make a pendulum. Count swings in 15 seconds and predict the next count.
2. Drop a ball and mark how high it bounces each time. Ask your child to predict the next bounce.
3. Watch a swing at the park and talk about the back-and-forth pattern.
