Learning Goal(s):
1.Students will conduct an experiment where blade angles are the variable and wind speed is constant.2.Students will conduct an experiment where blade angles are constant and wind speed varies.3.Students will collect and analyze data to provide a conclusion to the questions: What is the optimal blade angle for generating the most energy? What is the optimal wind speed for generating the most energy?4.Students will research prevailing winds and use a provided map of their region to indicate wind speed and direction.5.Students will propose locations for wind farms based on optimal energy generation and zoning restrictions.6.Based on their proposals, students will determine a range of potential kilowatt generation from wind power.
