Sunbathing skin damage
Liz and Dallas from the BBC One series 'Bang Goes the Theory' compare the effects of UV light on different skin types. Experiments in the laboratory and Dallas sunbathing allow the UV skin damage to be assessed. The proportion of the skin pigment melanin is examined in relation to the sensitivity to UV light resulting in skin cells and DNA damage. Side effects of sunburn including pink, sore, inflamed skin are directly caused by UV light damaging the skin cells. This damage can penetrate the skin and affect the DNA. The immune system can repair some of this damage, but repeated damage may lead to possible future skin cancer.
First broadcast on BBC One on 'Bang Goes the Theory' in September 2010.
Link to sun cream effectiveness experiments – e.g. UV beads spread with different factors of sun cream. Students could consider using photographic paper in different wavelengths (link to the Electromagnetic spectrum). Short summary clip, could be used as a brief recap/ plenary for a crude oil extraction lesson. This clip accompanies a BBC Teachers' Pack to support Series 3 and 4 of 'Bang Goes The Theory.' The pack can be downloaded from bbc.co.uk/schools/teachers/bang/
