Floating Toys

The challenge was to build a boat using one piece of tin foil. 

We spoke about gravity pulling the boat down and upthrust pushing it back up.

We thought about the foil and how it behaved in water when it was a sheet of foil and when it was all balled up.

We thought about boat shapes and how they were able to float. Then we took the foil and made a ship of our own design.

We randomly picked four people to test their boats.

The boat to beat at the moment held 250 cm cubes!!! 

We will all try our boats tomorrow:-)
