3rd Grade Paper Helicopter Design

3rd grade students experimented with different paper helicopter designs.  Each student created a design the increased the speed of the fall.   They found adding paper cliops or making the helicopter blades smaller helped the helicopter gain speed as it dropped.  Each student created a design the decreased the speed of the fall.  They found making the wings wider or adding a large base helped to slow the flight downward.  Many of the students suspected the weight of the paper had some effect in the change of the speed.  We also discussed the difference in air resistance that caused the change of speed.  Students were aware of the force of gravity in the activity, but learned the importance of air resistance, too.   This will help us in later classes as we design and test different sails and windmills.
