Having taught in the UK and abroad, I've experienced teaching many different syllabi including SABIS, AQA, WJEC and Cambridge. I develop resources to help teachers model key concepts, provide practice for students and include answers to help students self-assess their work. Planning for a 27 lesson week can be stressful to say the least, so I hope you find my resources useful. Thank you for choosing my lesson/s, I hope they enrich your teaching practice and make your life easier.

This PowerPoint is an essential teaching aid for understanding energy calculations in chemistry. It guides students through calculating energy changes using bond energies and determining whether a reaction is exothermic or endothermic.

The resource covers key learning objectives: explaining why bond breaking is endothermic and bond making is exothermic, analyzing reactions in terms of energy transfer, and performing accurate energy change calculations using the correct units (kJ/mol). It includes definitions, worked examples, and practice problems to reinforce understanding. Starter activities prompt students to review concepts like activation energy, reaction profiles, and the energy changes associated with chemical processes.

Students will work with bond energy values to calculate energy changes in various reactions, such as combustion and synthesis. They will also interpret the significance of negative and positive energy changes, linking them to exothermic and endothermic processes. The resource highlights the importance of bond energy in understanding chemical reactivity and energy conservation.

This ‘.pptx’ file is fully editable, enabling teachers to adapt the content to specific curricula or student needs. It’s ideal for high school chemistry lessons and is aligned with many science specifications. This resource has been refined for clarity and engagement, ensuring its relevance as a tool for teaching energy changes in chemical reactions.
