Wind Turbine Blade Aerodynamics STEM Challenge (ESS05) | Middle School Earth & Physical Science (Grades 6-8)

? WIND TURBINE BLADE AERODYNAMICS STEM CHALLENGE (ESS05)

3-Page STEM Activity | Print-Ready PDF Format

Harness wind power, aerodynamic lift, and clean energy engineering! The Wind Turbine Blade Aerodynamics Challenge (ESS05) challenges middle school student teams to act as aeronautical engineers, constructing an optimized rotor blade assembly to maximize kinetic energy transfer and output in front of a test fan.

Students explore renewable energy engineering, aerodynamic lift vs. drag, blade pitch angles, rotational kinetic energy, surface area trade-offs, and average output calculations!
