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.

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 their application in indigestion remedies.

Material and Everyday Chemistry:

Products we obtain from the atmosphere and crude oil including how we can plan for sustainability and manage waste.

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 to help my son/ daughter:

  • 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
  • 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
