In Technology we are making cams. Cams are rotating machines. We are making them out of paper. First we cut them out with scissors. We cut the holes on the inside with a paper cutting knife. Don’t worry, it’s not dangerous. Then we took a ruler and folded on the lines. Lastly, we glued it in place. Mine is not working properly and I have to find a way to fix it. This week we are starting cranks.
