An Ampthill business is challenging pupils from all over the county to take on real life engineering problems in a bid to drive up participation in science, technology, engineering and maths (STEM) subjects and careers.
The one-day activities are being run in schools across Bedfordshire by technology firm Lockheed Martin UK Ampthill and educational charity The Smallpeice Trust.
More than 60 pupils from Mark Rutherford Upper School and Alban Academy in Great Barford, have spent a day designing and creating a system to recycle water on a new smart building.
They had to create a watertight container to collect and filter rainwater, before assembling and soldering an electronic water detector. They also had to make an electronic pump to transfer the water to another container, which could then be recycled to water plants or flush toilets in the building.
