Edisford Primary School took on eight other finalists to win an engineering competition sponsored by local firm Johnson Matthey.
The Year 6 pupils were tested on their maths, physics, logic and science skills in a series of four challenges which also promoted team building.
Pupils were asked to construct bridges, towers, build a boat to carry a load and make a shelter. All the tasks required engineering skills and were rigorously judged by staff from Johnson Matthey.
Head teacher Robert Pye said: “The team felt well prepared for the event, in part due to the school’s own Endeavour Award Badge Scheme. The Award Scheme aims to teach team building skills through activities such as making shelters and building and cooking on camp fires. The Endeavour Badge Award teaches pupils many different roles that are needed in order to build a successful team.”
