This is an adapted version of the revision lesson I gave to my top set class for the AQA spec (Chemical Changes). The fill-in-the blanks sheet is really helpful for pace and understanding as it's broken down. Try to demo sodium chloride!
The electrolysis race is available at https://www.tes.com/teaching-resource/electrolysis-basics-6330297 (I removed the question on impurities as it wasn't relevant).
I made the spot the 10 errors sheet but this was revision for strong/weak acids, so can be removed!

For the AQA Rates and Extent of Chemical Change topic. First lesson of topic on Measuring Rates (can add a practical in to extend the time; I only had half a lesson for this after a test review).
Easily adaptable :)
An easily adaptable presentation for the AQA electrolysis required practical (I ended up cutting it down with my top set, but have left it intact for TES).
