Primary 3 watched a video all about castles in Scotland. We found out that castles are so strong because the strong and heavy bricks are always on the bottom.
We worked with a partner to design our own castles. We had to cut out all the different sized bricks. There were four rules that we had to follow. The most important one was that the heaviest bricks had to be on the bottom and we were not allowed to put a heavy brick on top of a lighter brick.
Our finished designs look really good and they are all different.
