How tough is your Sunscreen?
Do sunscreens really achieve their desirable outcomes? Can they withstand truly harsh conditions? Taking sunscreens away from the comfort zone of in-vitro testing and putting them to the test in-situ in Antarctica, seems like a great way to bring the teaching of Ultraviolet Radiation to a whole new dimension. Fast winds and low humidity levels are just some of the different conditions that will put the sunscreen to the test*.
Putting a real-life context into the teaching of subjects that may seem detached from reality helps students understand the importance of scientific studies to the world we live in. What I am trying to do is bring the real world into the classroom mixed and trying to achieve a simple, scientific and yet accurate in-situ method of testing the ‘efficiency’ of sunscreens.
Not only that, it also gives me the opportunity to educate students about the real dangers of UV to humans. Skin Cancer is now one of the fastest growing cancer in the UK, especially since many of you are taking skiing, scuba-diving or long beach holidays in very sunny locations and are not taking the right precautions!
Also, the level of Ultraviolet light in Antarctica is one of the highest in the world so the team will need to look after themselves!
Notes on the Science behind the Experiment

- Spectro what? A Simple guide to Spectroradiometry.
- Who’s Ozone?
- Give me Sight beyond Sight – Sensing Ultraviolet Light
There are over 700 sunscreen producs world wide and I can’t test them all in Antarctica. A selection of products targeted specially to the UK consumer market will be chosen for this scientific experiment.
