Mountain Science project

Melanie went to the Himalayas to climb Putha Hiunchuli, the highest peak she had ever attempted. As part of this trip she developed educational resources on the science behind some of the things you might want to think about if you’re venturing into the mountains.

Insulation 2 – a different lesson

Mountain Science - preliminary results 5 This post is about an experiment I did that gave quite unexpected results. As well as looking at insulation of particular fabrics, as in the previous blog, I wanted to have a look at the insulating properties of some

Ultraviolet radiation at altitude

Mountain Science – preliminary results 3 At higher altitudes, the intensity of ultraviolet (UV) radiation increases because there is less atmosphere above to absorb the ultraviolet rays.  The UV intensity also increases the closer we go towards the equator, so climbers from the UK who

Reduced air pressure & the body

Mountain Science – preliminary results 2 In the last blog we looked at how air pressure reduces at altitude and the effect this has on the boiling point of water.  This reduced air pressure also has a serious effect on the human body. Reduced air

Air pressure at altitude

Mountain Science - preliminary results 1 I've recently been looking over the data I took while on expedition to Putha Hiunchuli in Nepal.  The plan was to take some data and do some experiments looking at basic science in the mountains, particularly around issues that
