Variables Affecting Wind Turbine Power

Grades:
7-8
Lesson Number:
5
Description:
Now that students are familiar with how mechanical electricity generation works, they will build a wind turbine powered by a box fan. Different teams will test different turbine variables to see how the amount of electrical power is affected. After each team...
