Float or sink?

We have been learning about all the people who came to New Zealand before the invention of aircraft.  In room 1 we had to make a boat to see if we could design and create a structure that would float and hold a toy animal for 10 seconds.  The vessels all looked so different, but only two of them sank, which was pretty good!
Here are some photos of our testing...



If you want to make a boat that will float, you need to think about some important things...
Firstly, you need to have a shape that will stay stable and balance in the water.  Having air in it helps to keep it afloat.  The materials all need to be able to float.  Some of our boats were waterproofed with tape so they would not get soggy and sink.  A lot of real boats are made out of fibreglass, steel, aluminium or wood.
