 Beginner's Guide to Aerodynamics Wind Tunnel Aerodynamics Activity  Subject Area: Algebra I, Geometry, Physics Grade Level: 9-12 National Standards: Mathematics Demonstrate the ability to read written presentations of mathematics with understanding. Operate on expressions and matrices, and solve equations and inequalities. Science Physical Science: Motions and forces. Science as Inquiry: Understanding about scientific inquiry. Science and Technology: Understanding about Science and Technology. Technology Research Tools - Use content-specific tools, software and simulations (e.g., environmental probes, graphing calculators, exploratory environments, Web tools) to support learning and research. Problem-Solving and Decision-Making Tools - Routinely and efficiently use on-line information resources to meet needs for collaboration, research, publications, communications, and productivity.  Objective: After reading an explanation from a NASA Web-based textbook, you will demonstrate an understanding of the text by applying it to the calculation of area, velocity, and pressure in a wind tunnel. Beginner's Guide to Aerodynamics is a "textbook" of information prepared at NASA Glenn Research Center to help you better understand how airplanes work. Click Beginner's Guide Index to access the list of slides. Open the slides called Bernoulli's Equation (with text) and Wind Tunnel Aerodynamics (with text) and read the explanations of the relationships between air velocity, pressure, and density in a closed system of varying cross section like a wind tunnel. Then using the information shown at Wind Tunnel Aerodynamics Problems, complete the problems designed to demonstrate your ability to calculate for air velocity and cross section in a wind tunnel. Assessment: You, or you and your partner(s), will be evaluated on the accuracy or feasibility of your answers. Evaluation: You will demonstrate the ability to use information found on the World Wide Web to calculate for air velocity and cross section in a wind tunnel.   Submitted by: Dan Tuttle, Lorain Admiral King High School, Lorain, Ohio
