How does a whale float?

This is the question that Miss Harrison posed.

We then did some investigating about floating and sinking to find out if we could use our science knowledge to answer the question.

First we tested different objects to see if they would float or sink. We had to think about things that might help them float or sink and record our ideas.




















Next we found out that if you change the shape of an object you can make it float. When we put the blob of plasticine in the water it sunk straight to the bottom. So we changed its shape to see if it would float. Our investigations showed us that a boat shape would float.
