- 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

- 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.
