Have a look at the latest infographic on How the Sun affects our skin and why you need to use sun cream and cover up. This links to GCSE biology – genetics and mutations as well as GCSE physics – the effects of EM radiation. You can read further about nanoparticles in GCSE chemistry and how they increase protection from the sun.
With year 11, a quick recap on the factors affecting rates of reaction. These two demonstrations showed clearly that a higher concentration of hydrogen peroxide gives a faster reaction (elephant’s toothpaste).
