In outdoor learning week p5-p7 we built sandcastles and we had a contest on Tuesday in front of Port Ellen Co-op. We had bamboo sticks and a half a pipe to dig. We had to have a moat with water and renewable energy and also turrets. To get water you dig then enough water comes out. My team had a volcano in our build with lots of renewable energy. At the end my team won with ten points at the end.
