An educator at Jersey Shore Middle School in Jersey Shore, PA published a video on origami hang gliders that float on waves of air. The video explores the ways that the paper hang gliders model the same concepts as hang glider pilots, surfers and more to create lift to carry weight over a wave of air or water.
His students are engaged in the STEM concepts while enjoying playing with their origami toys. The class was able to visualize the way their hands or papers created lift with fog suspended in air to make a pseudo wind tunnel. This is a cheap and easy activity to recreate with your middle schoolers in the science classroom. Find the step-by-step instructions at sciencetoymaker.org.
