A TWENTIETH annual schools science festival has opened its laboratory doors.

More than 700 young people aged 13 to 15 from 24 schools will take part in this year’s three-day Durham University Schools Science Festival, which runs until Thursday (March 26).

Youngsters can investigate ancient bones, how plants find a mate and how the human brain adapts.

Experts in archaeology, biology, chemistry, engineering, maths, physics, sport and more are taking part.

Lorraine Coghill, the Ogden Science Outreach Co-ordinator, said: “The Schools Science Festival is one of the most important events in the university calendar and we are so pleased to be celebrating its 20th years.

“It gives us the opportunity to welcome young future scientists and engineers, providing them with the opportunity to experience many, varied aspects of science and technology through hands-on practical activities that they may not have access to at school.

“These activities will help them think more about their future and the world around them as well as boosting their confidence in their own abilities.”

More than 13,000 youngsters have attended the festival since 1995.
