What Will I Learn?

Chemistry is the study of matter and involves learning about different substances and how they can react with each other. This allows us to understand and understand the world around us.

In S3 - Higher, Chemistry is broken up into three units:

  • Chemical Changes and Structure
  • Nature's Chemistry
  • Chemistry in Society

 

Unit 1: Chemical Changes and Structure

This unit focuses on atoms and how they join together to form compounds. You will also learn how the structure of substances can affect their chemical and physical properties such as melting point, conduction of electricity and solubility. 

The different sub-topics, which we call Key Areas, for each level are shown below. The table also displays some of the content covered in each Key Area.

 

 

 

 

 

Unit 2: Nature's Chemistry

This unit focuses on a branch of Chemistry often called 'Organic Chemistry' which looks at carbon compounds. 

At N4/5, we start by learning about fossil fuels such as crude oil and start to look deeper at the structure of the hydrocarbon molecules which make up the fuel. We will also learn about other common carbon compounds such as alcohols and vinegar.

At Higher, we will learn about many more carbon compounds from those in fragrances and soaps to those in the proteins we eat in our diet.

 

Unit 3: Chemistry in Society

This unit focuses on important chemical reactions and applications of Chemistry that we use in our lives.

At N4/5 the main focus of this unit is metals with plastics, fertilisers and nuclear chemistry added in too.

At Higher, we start to look more deeply at how chemists can get the most out of chemical reactions.
