Mount Everest class is a career peak

A physics teacher from Carlisle has set a world record for high-altitude lesson preparation on Mount Everest.

Chris Mothersdale put together his 30-minute science lesson on the insulating properties of mountaineering clothing at a height of 7,010 metres.

Mr Mothersdale was on an expedition taking the north ridge route from Tibet up Everest. He prepared the lesson at Camp 1 of the climb and finally reached the 8,848-metre summit of the world's highest peak on May 16.

Teachers can download the video and data from his lesson, which has been recognised by the Guinness Book of Records, from the Web after June 28.

Mr Mothersdale has also been collecting data on the effects of exercise and the environment on the body during his ascent. He has 10 weeks of measurements taken as high as 8,200 metres of blood-oxygen levels and exposed skin temperature. All of this will also be available to download from the website.

Yewlands school in Sheffield is one of those taking the chance to use the information. It has been running a weekly science club after school to track Mr Mothersdale's ascent and use his information in some creative experiments.

The data will be updated daily until June 19. Students can win computer equipment in a competition for the best experiment based on his data.

The equipment Mr Mothersdale used to collect the data was donated by companies such as Canon and Sony, but the supply teacher met the pound;10,000 cost of the expedition himself.

Mr Mothersdale is in Kathmandu, Nepal and returns to Britain next week.
