- The pupils are supposed to build a working model of a hydroelectric power plant and power an electric device (e.g. a lamp) with it. They may copy design ideas from existing plants and should make a list of needed material. Try and error methods may be necessary to get everything working. They should then determine the power output of their model.
- knowledge: energy conversion in a hydroelectric power plant; functional principles and properties of hydroelectric power plants;
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 hydroelectric power plants
