Companion summary
Have you ever watched a ball zoom across the floor while a book just slides flat? Wheels on your bike and buggy use rolling to help things move easily and smoothly. A round ball rolls because it spins on its curved edge, but a flat book can only slide. When you finish, try pushing a pencil and a rubber and see which one rolls!
Look and Think!
