Our class have made wind turbines. We made a wind turbine out of paper, pencil, sticks, string, pin tape ,string and scissors.
We stuck the pencil to the table and attached the string to the pencil. After that we put a hole in the middle of the blades. There is a cup you cut a two holes in it you put your string through the holes in the cup . Then you get a hairdryer and push the blades around.
