Performance Assessment

In this lab experience, students are challenged to design a mini wind turbine and then investigate how their design affects power output. Students will discover that no single variable makes the difference in how much power the wind turbine can produce. All the different pieces must work together for the most efficient design. Blade material, angle, size, shape and placement are all important. By observing the designs of each group, students will see the best performing turbines had about eight midsize blades that tapered from top to bottom. They were inserted at an angle to the hub with only a little space at the bottom. Only the polystyrene sheet was ineffective as a blade material. The other materials worked well depending on shape and size.
