My Teacher is an Alien - Moon Crater

Materials

A tray or a plate

Flour but to make a permanent crater use plaster of Paris

Four different sized rocks



Method

1. In the plate or tray smooth out the flour so it is about 4 cm deep

2. Put your rocks in order from biggest to smallest.

3. From about a metre, let the first rock drop.

4. Lift it carefully out of the flour.

You have made your crater!

Repeat this with all the different rocks.

Observations

The rock that made the deepest crater was the biggest rock.

The higher the rocks dropped from didn't make a bigger crater.

Dropping the rocks in sand was different from dropping it in flour because it was a different material.
