We are the champions
The pupils have to work through five levels of challenges, starting in the classroom in January and winning through their school clusters to area finals, then to the final in London in September. Teams have to use their imagination, ingenuity and design flair to build the best possible model out of K'nex kits.
The competition is organised north of the border by Setpoint Scotland, and 50 teams took part in the final at Glasgow University in June. Castle Douglas Primary went on to represent Scotland.
As teams progress through the challenge, they have the chance to meet and discuss their models with science ambassadors from a range of industries who volunteer as judges.
