Last time I was talking about our elevator. Lena and I have finished building it and had dismantled it. I think that the elevator was the easiest simple machine there was to build because it often repeated most of the steps. After taking a picture of it we dismantled it. I thought that taking it apart would be fun but it wasn’t, in fact it was very difficult to take is apart because the connects are very connected. When you’ve connected something it is very difficult to take it if. We also had to build a model out of Lego. This time Lena and I decided to build a carousel. It wasn’t very hard because we had made Lego before in term 1. We didn’t get to finish it though because we ran out of time. On Friday we will be doing either Arduino or Humming birds.
