AQA GCSE chemistry - Unit 5 - Lesson 3 Bond energies and energy changes in reactions

Powerpoint lesson linked to workbook for the lesson with spaces for students to write answers, example examination questions and a mark scheme for the workbook.

Save time by avoiding the need for your students to write out lengthy sets of notes or draw diagrams. The work book includes spaces for marking and feedback including checked by teacher and verbal feedback given. Also leaves space to stick in improvement work or complete on the page. Could substitute for class books providing evidence for progress over time linked to success criteria.

Success criteria covered in this lesson are:

1. I understand that an exothermic reaction is one that transfers energy to the surroundings so the temperature of the surroundings increases.
2. I understand that an endothermic reaction is one that takes in energy from the surroundings so the temperature of the surroundings decreases.
3. I can explain and evaluate uses of exothermic and endothermic reactions
4. I can investigate the variables that affect temperature changes in reacting solutions such as neutralisation reactions.

I write Professor Bunsen resources to teach and test in my own classroom and try to make the resources compatible with a lot of the ways in which we are currently being asked to teach science including feedback and improvements and redrafting. The new specifications are intensive on time, and I am testing out moving towards workbooks and away from ordinary class books. These could be differentiated towards your own students.

I hope that I manage to make the new GCSE in chemistry engaging and exciting. Most importantly it could save you and your school time!
