In this science fair project, the student will make a wind tunnel to test how the formation of birds in flight affects flight efficiency. Make the bird models out of Legos and have fun with this project. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a section on terms, concepts, and questions, bibliography, list of materials and equipment, experimental procedure, suggestions on how to vary the experiment, plus a focus on the sort of careers this experiment might relate to.
