This week we learned about the wedge. We introduced the wedge with this short video. Then we got right to some experimenting.
We first tried to cut the play-doh using a block and realized it was very difficult and used a lot of force/effort. Then we tried with a wedge and realized it takes way less force/effort.
To reinforce this theory we then visually saw the build up of a block trying to go through rice krispies. Then we tried with a tooth paste tube (wedge) to go through the krispies and it was much easier.
Afterwards, we brainstormed and came up with all the different types of wedges.
