Activity description and learning aims:
  • The pupils are supposed to build a functional model of a wind turbine to power an electric device, e.g. a lamp. They may take cues from existing turbines and work with their form and features. They should discuss their own designs and determine the needed materials. Try and error methods may be required to get the electric device running. Pupils should then determine the power output of the model.
  • 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 design task; controversy about wind turbines
  • see unit description
Suggestions for use:
  • an industry visit at wind turbine factory is recommended
  • documenting steps in development and scheduling tasks
