Parachutes and Airplanes

Students begin by making model parachutes and observing how they create air resistance that slows the rate at which objects fall. Then they demonstrate how fast-moving air exerts less pressure than slow-moving air. Lastly, students construct model airplanes and relate the shape of the airplanes to the characteristics of their flight patterns. They see that some airplanes are designed to minimize air resistance while others are designed to maximize it.
