This is a culmination activity used after students have studied Bernoulli's Principle as part of a unit on forces and fluids. Students will use the Internet, textbooks, library resources and their cooperative learning group to design three paper airplanes using a sheet of 8 1/2 inch X 11 inch recycled copy paper and four inches of tape. The cooperative group whose plane had the longest flight in the air will get the most points.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
