A revision lesson covering sections 5.1.1 and 5.1.2 of the AQA trilogy science course- atomic structure and the periodic table. would also cover the GCSE Chemistry course. The lesson includes a variety of retrieval practice activities and exam questions. All slides animated- in some cases click the boxes to reveal the answer. The lesson includes: Properties of subatomic particles Atomic structure History of the atom uses of mass and proton numbers calculating relative atomic masses Electron configuration All answers included and all resources within the PowerPoint

A complete lesson covering how to calculate bond energies. This lesson would support both the trilogy GCSE and the separate Chemistry course. The lesson starts with a retrieval starter covering a variety of topics form molecules 1-4 with answers It then recaps endo and exothermic reactions with examples including a video It then covers what is meant by a bond energy using a variety of examples. Students then work through some examples The lesson then moves onto calculating overall energy changes in reactions before going through some examples. There are then some independent examples for students to work through with answers The lesson finishes with some exam question examples All resources provided
