KS3 Chemistry

Year 7

After an initial introduction to a laboratory, lab safety and how to use a Bunsen burner, students will be introduced to the very basic of chemistry: starting from the idea of particles and the atom and investigating chemical reactions and reactivity.

Term 1 Term 2 Term 3

Particulate Nature of Matter:

States of matter, the particle model, changing states, water, mixtures and separation techniques.

Atoms, elements and compounds:

Introduction to the Periodic Table and atomic theory, the difference between elements, mixtures and compounds, naming compounds and chemical reactions.

Chemical Reactions:

Classifying elements as metals or non-metals and looking at the reactivity series and energy changes as well as classifying reactions as combustion, reduction, oxidation or thermal decomposition. Also, how to change the rate of chemical reactions.

Year 8

In year 8, students start applying their understanding of chemical changes and reactions to how we have synthesised useful materials from the world around us.

Term 1 Term 2 Term 3

Acids and alkalis:

Classifying compounds as acids or alkalis and how we use indicators to test them, the neutralisation reactions of acids and the production of salts.

Periodic Table and Metals:

An introduction to what the periodic table tells us, and how we can use this to form balanced symbol equations for chemical reactions. A look at classifying materials from the periodic table and the methods for extracting metals, and how metals react.

The Earth and Atmosphere:

Sedimentary, igneous and metamorphic rocks and the resources we obtain from them along with looking at the carbon cycle and climate change.


A variety of tasks are set as homework in chemistry from research, exam questions, key word definitions, revision, extended writing, and topic worksheets amongst others.

5 ways I can help my child

1 Ensure that they complete their homework


Ensure that they know when assessments are taking place and are doing the necessary revision for them


Ensure that they use their PLCs (personal learning checklists) in order to self-check what they have covered in the specification
4 Ensure that they use their PLCs when revising


Ensure that they are using the AQA website to download, and complete, as many past papers as possible
