Activity description and learning aims:
  • The pupils are supposed to evaluate the capacity of a wind turbine depending on a number of different influences. The model provides methods to change the number, form and angle of attack of the rotor blades. They can also determine favorable wind velocities with the help of suitable devices.
  • knowledge: energy conversion in a wind turbine; functional principles and properties of wind turbines;
    inquiry: observation; description; creating and proving a hypothesis; systematizing; planning, conducting and evaluating design task; using models; comparison
    communication: online research; literature research; lab notes; schemes; manuals; group discussion; tables; diagrams; formula
    appraisal: evaluation of experiment; discussion about using wind power in regions with little wind.
  • e.g. Renewable energies kit from Horizon (see unit description);
Suggestions for use:
  • The pupils come up with possible influences on the power of a wind turbine, test them and present them easy to understand
  • An industry visit at a wind turbine factory or expert interview is recommended.
Recommended questions:
  • How does a wind turbine work?
  • Which types of wind turbines exist, which are planned?
  • How much useful energy could be generated by a wind turbine?
  • What factors influence the power of a wind turbine?
  • How can you measure the power of a running wind turbine?
  • How much power is generated by a local wind turbine?
