What is this course about?

Through studying Chemistry you will develop the scientific literacy needed to be a critical citizen in your everyday life, and through this develop the skills, attitudes, and relevant content knowledge needed in preparation for further study and science related careers. You will come to understand that:

  • Chemistry is the study of matter. Chemistry is about understanding the properties of different substances and how these substances can change.
  • Chemical transformations happen all the time, everywhere. Chemistry goes on continuously, all around us.
  • Chemists, and students who study chemistry, use their understanding of atoms, molecules, and ions – particles that are too tiny to be seen with our eyes – to explain and predict the properties and behaviour of different materials.

What will I learn?

All matter is made of particles

The fundamental particle from which all matter is made is the atom. There are approximately 115 different atoms which form the building blocks of the molecular and ionic structures that make up all the known substances.

The properties of materials derive from the identity and arrangement of particles

Atoms come together to form bonds during chemical reactions. The properties of the resulting materials depend on which atoms are combined and the way they are arranged.

Energy plays a key role in determining the changes that matter can undergo

Energy changes occur during physical and chemical transformations as the bonds between atoms or molecules are broken and new bonds are formed. Since energy can be neither created nor destroyed, energy will determine the changes that matter can undergo.

Chemistry is everywhere

Chemical transformations maintain the world around us. Most natural processes are based on chemistry and can be understood at a molecular level

What sorts of things will I do?

You will be involved in the active exploration of what chemistry is, and how chemists use a range of approaches and perspectives when viewing problems or issues through:

  • Connecting your new ideas to current and historical scientific knowledge and present their findings for peer review and debate
  • Developing your understanding of the relationship between investigations and scientific theories and models through investigations
  • Evaluating accounts of the natural world and considering the wider implications of the methods of communication and/or representation employed
  • Developing a coherent understanding of socio-scientific issues to identify possible responses at both personal and societal levels


Homework will be given each lesson, this will involve consolidation work and reading in preparation for the next lesson. In order to have the best chance of success, you must complete all homework on time.

These are standards are required as part of the course.
