A double lesson/ series of lessons looking at exothermic and endothermic reactions, labelling and explaining energy profile diagrams and calculating the overall bond energy for reactions.

The lesson features:

A series of basic recall questions from previous learning (questions on calculating P, N, E, alloys, electrolysis, covalent bonding, formation of ions, giant covalent structures and extraction of metals)
An introduction to the terms endothermic and exothermic using images for students to decifer the meaning of the terms
An animated introduction to energy reaction profiles, explaining how to label the diagrams and the difference between endothermic and exothermic reaction profiles
Numerous review questions in the style of past-exam questions to allow for teacher assessment of progress - labelling reaction profiles, recognising a reaction profile as endo or exothermic, describing reactions as exothermic or endothermic from temperature change values
A step-by-step introduction into bond energy calculations to reduce cognitive overload - pupils are shown how to calculate bond energies for single structures including several practice examples before being shown a worked example of how to work out whether a reaction is exothermic or endothermic using a bond energy calculation.
Two ‘have a go’ bond energy calculations with animated answers to allow for student self-assessment.
A 4 page worksheet containing practice exam-style questions on calculating bond energies, drawing energy reaction profiles and explaining whether reactions are exothermic or endothermic. Answers are included in the worksheet
Lots to choose from here!
