The first part of our DT project this term was investigating which 3d shape was the strongest for making a tower from. We considered a cylinder, triangular prism and a cuboid. Many of us were surprised that it was cylinder was the strongest and when we looked at pictures of castles more closely, we could see that there were lots of cylinder shaped towers.
The next stage was to have a go at make a cylinder ourselves and attaching it to a base using tabs. We also had a go at making a cone to place on top of the tower.
