Students will explore wind turbine performance and efficiency through the concept of wind shear and turbulence. Students will complete an experiment with kites and streamers that demonstrates where wind seems to be fastest and smoothest. They will record the data they gather on worksheets and answer questions.
The Details
Materials
- A large sturdy, single-line kite (a large helium balloon will also work)
- Streamers, caution tape, or field marking tape
- Measuring tape
- Protractor
- Medium-sized bucket or box
- Student reading passages and student worksheets
- Wind speed meter (we recommend a Kestrel here)
