Ships and boats

Ships and boats float in the water. We want to make boats which float in the water. We need various materials. We need gablo pieces, coloured paper , sticks, corks, nut shells and a bowl of water. We make the boats and put them in the bowl of water. They float. We blow to make the boats move.

We also put coins and wooden blocks in the water.
