Monday afternoon saw the Third Year heading down to the Pitt Rivers Museum for an Art workshop with Mrs Williamson.

Who needs fancy software to crazily distort facial features when you can just use a Fresnel lens? These chaps found my Fresnel lenses on Sunday in the science lab and set about distressing passers by. Only click on the thumbnails if you are feeling brave!

Some of the Fifth Year have been studying genetics. I have found a couple of quite good videos explaining some of the concepts. I am not a great fan of Rap as an art form but I think the following video is pretty good. It is funny how one’s attitude changes when the material is to one’s liking. […]

Copper oxide and magnesium 5L, continuing to look at the reactivity of metals, have been exploring the reaction of copper oxide with magnesium. This is an extremely powerful redox reaction and produced some explosive results. The copper is reduced and the magnesium is oxidised. We set up the reaction as shown above and used a […]

2N spent this morning trying to identify mystery objects under the microscope. The objects were: A mould, a bee’s wing, a blood smear, pollen, a fruit fly and a tiny printed version of The Lord’s Prayer.
