As part of Science week we all did experiments in our classrooms. My group did a rainbow spinner. All we needed was cardboard, a battery pack, a motor, some wires and markers. First we cut out a circle of cardboard, next we coloured it, the seven colours of the rainbow. After that we attached some wires to a battery pack and hooked them up to a motor. Then we put our rainbow spinners on to the motors. They turned a bright white colour. We then thought they weren’t going fast enough so we hooked up three battery packs to each of our spinners. They went really fast! Then Sean wanted to make them cut paper, so he cut zig zags onto his circle. He called it a chainsaw. It only cut a bit of paper. Our science experiment was a lot of fun, I really enjoyed it.
