Evaluate why experimental enthalpy values differ from accepted data. Students analyse heat transfer, apparatus heating, incomplete combustion and evaporation, then use cooling-curve extrapolation and justify practical improvements.
Use hot and cold reactions to distinguish the system from its surroundings, explain energy conservation, and classify endothermic and exothermic changes.
Connect thermometer observations, energy-transfer directions and energy profiles. Students practise the sign of enthalpy change, enthalpic stability, graph interpretation and error correction.
Build Q = mcΔT from scaling arguments, interpret specific heat capacity and practise calorimetry calculations with consistent units. The lesson also introduces standard-state conventions and experimental assumptions.
Students analyse artworks, compare artistic and descriptive accounts and reflect on the emotional, experiential, formal and cultural knowledge the arts can convey.
Students analyse viral cases, practise a four-step fact-checking method and debate trust, expertise and the spread of misleading information.
Students select specific objects, draft justifications and use peer questioning to strengthen the links between their objects and an exhibition prompt.
Students analyse propaganda and political speech, distinguish factual claims from value judgements and debate how ideology shapes political knowledge.
Students compare approaches to producing, testing and transmitting knowledge, map overlaps and tensions between knowledge systems and discuss the role of faith.
