valerie taylor on 09 Dec 12"Helicopter Drop by Bryce Hixson Take a single strip of copy paper and make three cuts and five folds to create a ready-to-fly helicopter. You can experiment with surface area and friction, and have a lot of fun adapting the design. Great way to teach the effect of gravity and friction on a falling object, experiment with torque and changing forces, and open the door to imagination and engineering."
