Students follow the AQA Chemistry course which consists of 4 separate units; each worth 25%. Units 1, 2 and 3 are examined by a 1 hour written paper, consisting of structured and closed questions. There is at least one longer response question assessing Quality of Written Communication in a science context on each exam paper. Unit 4 is an Investigative Skills Assignment (ISA) for which pupils complete a practical task and are then tested on their data processing, analysis and evaluation skills.

In unit 1 the topics are:

• The fundamental ideas in chemistry

• Limestone and building materials

• Metals and their uses

• Crude oil and fuels

• Other useful substances from crude oil

• Plant oils and their uses

• Changes in the Earth and its atmosphere

In unit 2 the topics are:

• Structure and bonding

• How structure influences the properties and uses of substances

• Atomic structure, analysis and quantitative chemistry

• Rates of reaction

• Exothermic and endothermic reactions

• Acids, bases and salts

• Electrolysis

In unit 3 the topics are:

• The periodic table

• Water

• Calculating and explaining energy changes

• Further analysis and quantitative chemistry

• The production of ammonia

• Alcohols, carboxylic acids and esters

For the Unit 4 Investigative Skills Assignment pupils plan practical ways to develop and test their own scientific ideas, including assessing and managing risks associated with practical work. All students will collect and process primary and secondary data, make observations, present their results in an appropriate way, analyse the data by looking for patterns and draw conclusions using scientific ideas.
