Paper helicopters
Today our class made paper helicopters. We all had to cut out different shapes from a template and then we folded them along dotted lines to make the rotors. We used paper clips at the bottom as a weight. We all dropped the helicopters from a height and watched them as the rotor blades were spinning around as they fell.we all noticed that when we bent the rotor blades the other way round that the blades changed direction in thier spin.We all had races with our helicopters to see which one was the best. Brandon said the best one should be the helicopter that stays in the air the longest.
