Inquiry Walls

LI: Create wall planning for inquiry to plan on making a 10cm tall wall (max) and a 5cm thick wall to defend 2 helicopters from a mini pencil catapult.

This week for Mr wongs inquiry we made plans on how to build 4 different types of walls. On this presentation I created 4 plans on how to make a pallisade,stone wall,castle wall and a rammed earth wall. The pallisade wall is a wall of sticks or wood. A stone wall is a wall with plain rocks, which is hard to make with no sand or anything to stick it together. The Castle wall is a wall of rocks and wet sand in between to hold the rocks together. And the Rammed earth wall is a big chunk of sand shaped in a wall.

I created the palisade wall out of toothpicks and I created the Castle wall with rocks and sand. Ellenora had helped me create these walls and once we tested the walls our Castle wall (Rocks and sand) stood  stronger than our pallisade.
