Lesson details
Key learning points
- Fertilisers contain nitrogen, phosphorus and potassium compounds to promote plant growth.
- Ammonia is a feedstock for manufacture of fertilisers, explosives, plastics, dyes and cleaning products.
- Ammonia can be used to manufacture ammonium salts and nitric acid.
- The laboratory preparation of ammonium salts is not the same as the industrial preparation.
Keywords
Fertiliser - a mixture of soluble chemicals added to soil that replace the mineral ions needed by plants, to promote plant growth
Eutrophication - a term used to describe when nutrients accumulate in bodies of water, which results in an increased growth of microorganisms that reduce the oxygen availability in the water
Salt - an ionic compound formed from positive and negative ions electrostatically attracted to each other
Batch process - a manufacturing method made up of discrete stages, rather than a product being constantly produced
Continuous process - a manufacturing method where a product is constantly produced
Common misconception
Ammonia and ammonium are the same thing.
Carefully compare the different chemical formulae, structures, and distinct uses in fertilisers vs. industrial applications. Use visual aids to reinforce these differences.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
