Walls | Castle & Palisade

L.I: To create a defensive wall.
This week for Inquiry we have been studying 4 different walls which are Defensive wall (Castle wall), Palisade, Rammed Earth wall, and the Stone wall. Later on we had to create a google presentation as a planner for the walls of how we are going to make them. To show our learning, we had to really create the walls using different materials. We had to create a castle wall, with one other chosen one. My group and I decided to do the palisade as well. In our groups we had to make sure they were stable to be tested after being created. We made our castle wall using stones (rocks) and sand, and the palisade wall with toothpicks. Our surface was sand that was in a tray. Our teacher had created a catapult to shoot things at our walls to see how stable and they were. We used a whiteboard to count how much times the wall was hit, without being broken down. Our walls did pretty good. Behind the walls were a helicopter and our walls were to try and protect it. Everyone's groups walls were tested out and everyone's results were different.
