Pupils from Merchiston Castle School have been awarded a number of prestigious science prizes after impressing judges at The Big Bang Scotland Fair.
The pupils will now represent Scotland in the UK finals of the National Science+ Engineering Competition in Birmingham next year.
James McDiarmid was awarded the overall Scotland Young Engineer of the Year 2013 award and the Young Engineers for Britain Regional Engineering Excellence Award for designing a GSM mobile weather station, which can relay data back to a phone or server for remote monitoring.
Another team, made up of Cameron Nicholls and Andrew Hunter, won the Best CREST Engineering and Technology Award at gold level for their project, Testing PV Panels, which developed a system to test the efficiency of a solar panel.
Host Greg Foot said: “The Scottish winners will present their projects and have a chance to show off all their hard work to prospective employers and universities as well as VIPs and judges.”
