- The pupils are supposed to build a working model of a hydrogen vehicle. They may take cues from existing vehicles and copy their form and features, discuss their own design ideas and make a list of needed material. Try and error methods can be used to achieve maximum efficiency.
- knowledge: energy conversion; functional principles of fuel cell and electric motor; properties of fuel cells and electric motors
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 hydrogen
|
- e.g. Hydrocar or H2 Racer from Horizon (see unit description)
- electric motor(s), fuel cell, electrolytic cell, electric supply, cables, hydrogen storage
|
- The pupils should determine what factors influence the efficiency of a hydrogen vehicle, test them and present their results easy to understand.
- An industry visit at a hydrogen vehicle factory or expert interview is recommended.
|
- How does a fuel cell work?
- Which materials do you need for building a hydrogen vehicle?
- Which values influence the efficiency of your hydrogen car?
- Whose hydrogen car is the best?
