Rules for 2025
What needs to be done?
A group of at least 2 to max. 4 pupils or trainees form a team and construct an ultralight solar mobile. The team takes part in the race on the day of the competition. The race is run on a circuit built in the shape of a figure eight. The results of the races count towards the overall result, as does the evaluation of the two posters that have to be produced. The posters are a poster describing and depicting the model and another poster dealing with an overarching theme.
There are three separate evaluation classes:
- Pupils in grades 5 to 8, with freely designed vehicles
- Pupils in grades 5 to 8, with vehicles from a predetermined kit
- Students in grades 9 to 13 and apprentices
The requirements for the two classes differ during the race. Classes 9 to 13 and trainees drive the same circuit as classes 5 to 8, but have the additional requirement of having to master a change of direction.
