Science expo

We had to choose from water energy, wind energy, solar ernergy. I searched water energy and then i found a water turbin and it looked cool so i did it. Because it looked easy and me and my mom decided to do it. I was working with calum and then calum decided to go with oliver so i was by myself. My turbine spined fine and and my pully system. My problems were that my light bulb did not light. On my poster i was happy but at the end i was stressing because all the other kids were done but i was not. I was filing fine and happy.
