Introduce scientific design and variables through this simple lesson of building paper helicopters. Activity includes a link to a video on how to make helicopters.

Students learn about weight and drag forces by making paper helicopters and measuring how adding more weight affects the time it takes for the helicopters to fall to the ground.

Can you build a helicopter with popsicle sticks, rubber bands, paper clips, and cardboard that flies at least ten feet in the air and stays up for three seconds while carrying one penny? Use this site to accomplish this with a lesson...

Students can experiment with a home-made helicopter that lets them change the blades to see how real aerodynamics work.

Have fun making different kinds of flying vehicles. You will learn how to make a paper airplane, helicopter, rocket, blimp, etc.

This site from the Illinois Institute of Technology provides a student lab activity in which the flight of a paper airplane is investigated and studied. Designed for primary grades, but easily adaptable for junior high learners.
