A round ball rolls down a ramp and goes far, while a block with flat sides slides down the same kind of ramp, showing that shape changes how things move. Then a rubber ball and a clay ball of the same size drop from the same height: the springy rubber ball bounces and the soft clay ball squashes with no bounce, so the video ends with "Shape and material change how things move."

Transcript

What the lesson says

Will it roll, slide or bounce? Let's find out!

Here is a ball. It is round.

The round ball rolls down the ramp.

Here is a block. It has flat sides.

The block does not roll. It slides.

So shape changes how things move.

Here is a rubber ball. Let's drop it!

Boing! The springy rubber ball bounces back up.

Here is a clay ball. It is round too.

Splat! The soft clay squashes. No bounce!

Rubber and clay are different materials.

Shape and material change how things move.
