How Things Move: Rolling, Sliding and Spinning — Answers

Part A: Ways things move

Read the box. Then circle the best answer.

Things can move in different ways. They can roll, slide, spin or bounce.

Round things, like balls and wheels, roll. Things with flat sides, like books and boxes, slide.

A spinning top spins around and around. A ball can bounce up and down.

Something needs a push or a pull to start moving.

The round wheels roll, so the car moves easily.

Part D: Working scientifically: roll or slide?

Try it with a grown-up. Then check your predictions.

Make a ramp with a book and a tray. Try an empty can on its side and then standing on its flat end.

9.Predict: will a can roll or slide down a ramp if it lies on its side?

Answer: It will roll, because its curved side is round.

10.Predict: will the can roll or slide if it stands on its flat end?

Answer: It will slide (or stay still if the ramp is not steep), because the flat end cannot roll.
