Students build two different gliders — a hamburger shaped glider and a hot dog shaped glider.

• Build two gliders
• Conduct experiments using scientific method
• Integrate multiple subjects

They then conduct a series of experiments that use the scientific method to compare the performance of these gliders. Integrate science, language arts, and math. Developed by Rick Crosslin. Includes materials for 32 students and instructions. Grades 3–6.
