Boats Float

1. Fill the sink or bucket with water.

2. Place a ball of play dough in the water.

3. What happens to the ball of play dough?

4. Take the ball of play dough out of the water and mould it into the shape of a boat.

5. Place the boat made of play dough into the water.

6. What happens to the play dough?

Why this happens:
The ball of clay sunk because there was not enough water pushing against it. The boat floated because it had a greater area for the water to push against.
