For National Science and Engineering Week P3/4 were trying to Beat the Flood. This was a challenge set by Practical Action to try and design and build a floodproof house that could stand up to flooding and monsoon rains. The design also had to be sustainable, use materials available on a small Pacific Island and be cheap to build. This innovative design has a water catcher and grows food on the roof so that people can still eat if the land around has been flooded.
