We are making cams right now! They are made out of paper which is very cool because it will work like a real camera… but it cant take a picture. I finished E last night. I think that the cams are hard but also fun. The cam is a weal and axial because the circle acts as the weal. A weal and axel is also a lever. When you turn a screw driver you can see the parts of an axel and a weal! The weal would be the part you hold and the axel is the medal pole. We are also learning about followers in cams. The follower moves up and down tracing the shape of the cam as it turns so it can move.  All of this has to do with cams because that makes up a cam.
