I created this lesson for A2 Chemistry OCR A specification, however it can easily be adapted and used on any course/spec on which you need to teach this topic.
It is activity focused, step-by-step, includes and addresses common misconceptions and has relations to the ‘real world’. I have tried to explain what many find a difficult topic in a relatively simple way. I hope you find this useful, please review and let me know :-)
It refers on one slide to the ‘RSC Starter for Ten Advanced Chemistry’ worksheets which are an excellent resource and can be downloaded for free (along with answers) from the RSC website.
