Wind Turbine Blade Design
http://learn.kidwind.org/learn/wind_turbine_variables_bladedesign

Kidwind Project

Students go through the design process and the scientific method to test the effect of blade design on power output. There is an optional extension to use the data to create an optimal set of wind turbine blades.

Activity takes at least 5 class periods and can be extended. Additional materials required.

Benchmarks for Science Literacy

Energy from the sun (and the wind and water energy derived from it) is available indefinitely. Because the transfer of energy from these resources is weak and variable, systems are needed to collect and concentrate the energy.

Notes From Our Reviewers The CLEAN collection is hand-picked and rigorously reviewed for scientific accuracy and classroom effectiveness. Read what our review team had to say about this resource below or learn more about how CLEAN reviews teaching materials
Teaching Tips | Science | Pedagogy | Technical Details

Teaching Tips

  • Teachers need to allocate storage space for the wind turbines during construction.
  • Educators will want to provide additional content about the science of wind energy as a source of renewable energy, including energy storage, transmission, etc.
  • Activities like this have been used in energy, weather, and environmental science units as well as in physics classrooms to teach aerodynamics.

About the Science

  • Models the scientific process - esp. hypothesis testing.
  • The testing of actual blade models will reinforce the importance of blade design.
  • Passed initial science review - expert science review pending.

About the Pedagogy

  • With additional scaffolding, it can be used in energy, weather and environmental science units or to teach students how to properly set up and use the scientific method while exploring something new and different.
  • Technology teachers could use this lesson to teach about the design process and integrate science concepts.
  • The activity could also be used as a small segment in a month-long exploration of wind energy (it would require more scaffolding to do this effectively).
  • Great teaching materials with good handouts.

Technical Details/Ease of Use

  • Substantial preparation time required to implement activity.
  • Educator must be familiar with wind turbine models and should experiment with one before attempting to do this project.
  • The resource is built around the background materials and kits available for sale at http://www.kidwind.org, however materials can be purchased elsewhere.
  • Educator needs to provide specific instructions to standardize turbine testing.
  • Links that are broken: http://www.windpower.org/en/tour/manu/bladtest.htm and http://www.awea.org/projects
    Instead use http://www.windpower.org/en/ for Danish Wind Association site and http://www.awea.org/ for American Wind Energy Association site.
