A good revision lesson today - hope it made you more aware of what you do (& don't ) know. The resources should also help. I am sure you will find the audio files good too.
For a powerpoint about ocean currents written By Ollie Bray follow the link to Odblog and then scroll down to Tuesday 5th February - well worth looking at
Keep calm, warm, well fed and it will all be over before you know it ! Keep using those revision timetables.
A snowy photo for you to go with -5 temperatures - more snow for tomorrow too !
