Which shape was the slowest?
Which shape was the fastest?
How does the shape make a difference to the speed of the fall?
WHY?
Why are boats and ships the shape they are?
Why is it hard work to walk through water?
We created a fair test to find out if the shape of the blu-tac makes a difference to the speed at which it falls through the water.

When I took part in the experiment and I found the flatter object took longer to sink than the more pointed object because the pointed object cut through the water like a knife through butter.

I don't know about the shapes because I was investigating another way but I do know that boats are streamline so they cut through the water but when we walk through the water our legs aren't so the water fights against us.

the shape makes a difference when falling through water because the water resistance is pushing things up so when you put a flat object in the water it go slowly because of the water pushing it up but if you put a pointed object in it will cut through the water making it go faster.

Boats are pointed at the front so that they can push the water away, around the side of the boat. The shape of a boat is important as it can even make metal float!
