The video is being made. Until it arrives, here is what it will say (286 words, about 143 seconds):

The swing, the caught ball, the tapped ball, the clay, and Orla's test. Here's everything we found out.

A swing hangs still. Nobody touches it. It stays still.

A girl pushes the seat, and the swing starts moving.

A push or a pull can start a still thing moving. With no push or pull, a still thing stays still.

Now a ball rolls toward a girl. Her hands push against it, against the way it moves. It stops.

A push or a pull against the way a thing moves slows it down, or stops it. Stopping needs a force too.

Now a ball rolls straight, and a foot pushes it from the side. It turns onto a new path.

A push or a pull from the side sends a moving thing onto a new path. It changes direction.

Now a girl squeezes a ball of clay, and it's flat. A boy pulls a rubber band, and it's longer.

A push or a pull can change a thing's shape.

And Orla's test: the same car, the same start line, the same floor, and one thing changed: the push. A push from behind started the car moving to the mark; a push from the side started it moving sideways.

In a fair test, you change one thing and keep everything else the same. Then you know what that one thing did.

So, back to the kicked ball. The kick started it. Her foot pushed against it and stopped it. Her tap from the side turned it.

Stopping and turning needed a push too. That's the whole topic: a push or a pull can start a thing, stop it, turn it, or change its shape.

Okay, now your turn.

It ends there. Then answer the questions below.
