Student's self-study

Task

Assignments:

1. Using example, develop tasks for one of the following videos: your video worksheet should have THREE PHASES: pre-watching, while-watching and post-watching exercises.

How to Calculate Change in Entropy

Calculating ΔG° for a Stepwise Reaction

How to Calculate Change in Entropy

Calculating ΔG° for a Stepwise Reaction

Learning objectives:

11.3.1.7 understand the underlying principle of Hess’ Law and be able to use it calculate enthalpy changes in reactions	11.3.1.8 be able to calculate ΔH from bond enthalpies
11.3.1.9 be able to construct a Born-Haber cycle and compare lattice energies from this approach with those from other calculations	11.3.1.10 be able to define and use the concepts of free energy change (ΔG) and entropy change (ΔS)
11.3.1.11 understand that enthalpy change alone is not sufficient to explain spontaneous changes and recognise the role of entropy	11.3.1.12 know and be able to use the equation ΔG = ΔH - TΔS to show how ΔG changes with temperature and to find the temperature at which a reaction will proceed

2. Develop one of the fragments of Lesson plan: you should use

• a lesson plan template (Appendix 1);
• one of the CLIL techniques (Appendix 2);
• teaching methods; and
• learning objectives above.
