Prep for mocks
Prep for A-level year 2 mocks. Not done differentiation and Integration, so can only do about 1/3 of the paper since most of the paper is A level, not AS, so many of the students are only able to do AS questions, not the harder A level ones.

Online lessons
Teaching online with Zoom. We can still do experiments, but they are harder by remote control or have to be demos. But still, with a selection of cameras and tools, we can still make great lessons to be remembered.

Electrolysis
AQA required practical electrolysis but quite a few year 11 students had not done it so after a quick refresher on the theory they had a go and correctly predicted the chemicals and successfully tested for oxygen, hydrogen and chlorine gases.
