They also took part in interactive workshops, one looking at the energy efficiency of hydrogen cars and the other showing how a wind turbine generates electricity.
During the workshops the students built their own hydrogen cars, which involved them looking at alternative ways to power vehicles and then racing their cars to test the power.
The students also worked in groups to build mini wind turbines, while learning how they work and how the energy they produce is used.
Among students who took part was Josh Snaith, 14, of Bydales School, Marske. He said: 'We鈥檝e been measuring the amps from a solar panel and making a wind turbine to generate electricity. It鈥檚 been really interesting.'
Alex Grange, 14, of Northfield School, Billingham, said: 'We鈥檝e been learning about energy and cleaner energy sources. It鈥檚 been really educational, but fun too.'
Taking part in the event were pupils from the following secondary schools, Northfield in Billingham, Oakfields in Middlesbrough, Macmillan College in Middlesbrough, Freeborough Academy in East Cleveland and Bydales in Marske.
