Imagine a footballer about to kick a ball. Sometimes they give a little kick. Sometimes they give a big kick.

Which kick do you think sends the ball further? Show me with your hands: small kick or big kick?

You already know a push makes something move.

Which push will send our car further — a small one or a bigger one?

One pair works at each floor lane. Everyone else watches and helps say small or bigger.

If you are the pusher, give a small push from the start line, and your partner puts a marker where the car or ball stops.

Then, with the same car and the same start, the pusher gives a bigger push, and the partner marks that stop too.

Look at the two markers together and decide which push went further. Then swap, so every child gets a turn to push.

Look at the two markers on the lane nearest you.

Point to the stop after the small push. Point to the stop after the bigger push.

Which marker is further from the start? Tell the child beside you what you noticed.

Sit where you can see the front floor lane. We will watch and guess together.

First a small push. Guess where it will stop, then watch. The teacher leaves a marker there.

Now a bigger push with the same car from the same start. Guess again, then watch the second marker go down.

Look at both markers. Which push went further?
