This lesson is designed for the NEW AQA Trilogy Chemistry GCSE, particularly the 'Earth’s Atmosphere’ SoW.
 
Firstly, students are shown how to ammonia produced in the Haber process is reacted with different acids to form different ammonium compounds before being used in fertilisers.
 
Firstly, students will investigate how to produce ammonium sulphate in the lab - they will be provided with a practical worksheet which they will need to work their way through in pairs. This involves a titration, which they should have carried out before, their results can be recorded in the table provided on the worksheet.
 
Next, pupils will watch a video on the production and use of fertilisers - using the information provided int he video a set of questions needs to be answered. This work can then be self-assessed using the mark scheme provided.
 
Lastly, pupils will be given a set of information about how fertilisers are made in the lab compared to being made by chemical industry. Using this information students will need to complete a comparison table which focuses on starting materials, equipment, safety, yield and running costs. This work can be self-assessed using the mark scheme provided.
 
The plenary task requires pupils to write three quiz questions to test their peers knowledge on what they have learned during the lesson.
