OBJECTIVES: Students will build a simple wind tunnel and test out 2 glider wing shapes at different angles of attack. Students will record results and their observations just as engineers do. Students can use a "virtual wind tunnel" and observe how air flow changes over different wings and angles of attack. NATIONAL SCIENCE STANDARDS: Forces and Motion, Science as Inquiry MATH STANDARDS: Angles, Relationships of Shapes, Symmetry, Asymmetry ENGINEERING SKILLS: Documenting and Recording Data, Application of Science Principles to Engineering, Construction; Basic Aerodynamics

LECTURE AND PREPARATION TIME: 30 minutes LESSON TIME: 60 minutes WORDS TO KNOW: aerodynamics aeronautics angle of attack camber compress drag force glider lift subsonic supersonic symmetric test section thrust wind tunnel
