Activity description and learning aims:
  • The pupils are to build a working model of a solar collector, following the example of existing ones and copy their form and features. They should discuss own design ideas and make a list of needed material. Try and error methods may be required to maximise the efficiency of the model.
  • knowledge: energy conversion in a solar collector; functional principles and properties of solar collectors
    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 solar collectors
  • see unit description
Suggestions for use:
  • The pupils should think of possible influences on the efficiency of their solar collector, test them and present their results easy to understand.
  • An industry visit at a solar collector factory or expert interview is recommended.
Recommended questions:
    • How does a solar collector work?
    • Which types of solar collectors exist, which are planned?
    • How much energy can be collected by your model?
    • Which values influence the power of a solar collector?
    • Are solar collectors more expensive than other methods of power generation?
    • What do you need for building a solar collector? Which materials are useful?
    • Is your solar collector efficient enough to …?
    • What do experts know about building a solar collector?
