You will use this hands-on activity to help high school students learn about the engineering process while exploring wind power.
You will introduce students to wind turbines and discuss how energy is generated from wind. Students will design and make turbine blades by working through the engineering process to modifying their blades to make the most efficient use of the wind. Students will then use their tested turbine to investigate what happens to the voltage of electricity as it is transmitted along an electrical wire.
To prepare for your classroom visit, about two weeks in advance, review the information in the Engineer Guide and the materials provided for this activity. Contact the teacher and provide her/ him with the list of materials you need the class to gather for the hands-on experiment.
