Full presentation: notes, worked questions, Quiz and homework. Ideal for online and live teaching: Tested regularly via Kahoot quizes as you teach along (link provided in ppt). Colourful, engaging and easy to understand. This is part of section 8 which was taught as multiple two hour lessons using active recall and spaced repetition to ensure knowledge of the chapter was continuously tested. A full section 8 presentation (Energy and Matter) will also be uploaded. Feedback appreciated.
