This lesson is designed for the NEW AQA Trilogy Chemistry GCSE, particularly the ‘Rates of Reaction’ SoW.
 
This lesson begins with an introduction to reversible reactions, including the example of thermal decomposition of ammonium chloride.
 
Pupils will then conduct an investigation into the energy changes which occur during a reversible reaction, using the practical sheet provided students will carry out the experiment and record their results in the table provided. The reversible reaction from this investigation is then shown on the board, with an explanation of the energy changes that are taking place as the reaction moves in either the forward or reverse direction.
 
Pupils will now watch a video on energy changes which take place during a reversible reaction, using this they will need to answer a set of questions. This work can be self-assessed using the answers provided on the PowerPoint presentation.
 
Pupils will now need to complete a ‘Quick Check’ task which includes questions within the module of ‘Rates of Reaction’, students can then self-assess or peer-assess their work using the mark scheme provided.
 
Finally, pupils can complete a crossword which summarizes definitions used within the ‘Rates of Reaction’ module, the answers for this are provided for self/peer assessment.
 
The plenary task required pupils to complete an exit card listing 3 things they have learnt today, 5 key words and 1 question to test their peers knowledge of a subject.
