Explanation
Things move too. A ball can roll and bounce. A wheel can spin. A toy car rolls on its wheels. A child can slide down a slide. A tin can rolls on its side. A box does not roll, but it can slide over the floor. We can test things to see how they move.

| ball | yes | yes |
| tin can | yes | no |
| box | no | no |
