Several forces act on a kite when it is in flight. This video from Curious George demonstrates how a kite's design allows you to manage and adjust to the pushes and pulls the kite is subject to, primarily due to wind. As the students build kites using plastic trash bags, wooden dowels, and string, they learn the name of each part, including the sail, the spine, the crossbar, and the tail.
