Students build a four-wing paper boomerang. In this aeronautics lesson, students construct a paper boomerang and identify the forces at work during flight.

Students construct boomerangs. In this aeronautics lesson, students use a file card, scissors, and pencil to develop their own boomerang.

Students cut out the pattern of the Four-Wing Boomerang and trace it on to one half of the file folder. They practice throwing it.

Students make and fly small boomerangs made from file card paper.

Students investigate the physics of flight through various experiments. In this physics lesson, students construct different flying objects. They explain the dynamics that make these object fly.
