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.

Recently we build electroscopes. Sir Williams also did this experiment. In this experiment we are trying me make the tin-foal inside the jar move. Now I will tell you it wasn’t easy to make the electroscope. You needed certain materials and it took me a couple of tries to get the tin- foil to move. I used a sweat-shirt to get the balloon staticky. The first time I used a piece of cloth  and the tin-foil didn’t move. The second try I used my pants and it didn’t work. The third time I used an old sweatshirt and then tin-foil moved for a few second then stopped. When the tin-foil did move I was surprised and excited. I looked back in the flip grid  and I looked closely and it did move! I was disappointed for when it stopped moving though. After the flip grid I wanted to keep using different objects to make the ti-foal move. I rubbed the balloon agents my hair and it moved for longer! Over all this project was very fun and I don’t think it would be something you do everyday so I liked the opportunity to do it. I cant wait for the next project!

This week we made trusses. I made a cube. I made my cube out of baby carrots and toothpicks. It was a little hard to build it because sometimes the toothpicks didn’t reach both carrots so I had to se tape or squish them together. I also had to cut the toothpicks if they were to long. Most of them weren’t but a few were. After I finished building them I had to set up my flip grid. I got three books to put on the trus. Two were heavy and one was light. My goal was to get al least one heavy book on my truss. I ended up putting the light book on first and not supisingly it didn’t fall. I put one heavy book on slowly and it didn’t fall! I got so excited because I though it was going to fall. I reached for the next book but as I did downnnn went my trus! I said “No it fell!” But then realized that the fall destroyed my whole trus. Bummer I wanted to keep it for a bit. Overall this project was very fun and easy! I would definitely like to do it agian!
