I didn’t set any prep but if you’re reading this then maybe you can spare a few minutes to do some research into how the Moon was formed?

4 Che – As an introduction we watched a documentary about how hydrogen peroxide caused the sinking of the Kursk, a Russian submarine in 2000. Click here for an in-depth report from the Guardian newspaper.

2R – You started work on a poster project about fossil fuels and you’re going to carry on with that for prep. You can find some good information here.
