Students will gain an understanding of matter needed to underpin the development of study in all other aspects of chemistry. They will learn about its properties, how it reacts, classification and the energy involved at a particle level. Scientific inquiry is used to show practical examples of the behaviour of atoms, molecules and ions. This strand provides opportunity to model the scientific method to plan, observe, deduce, analyse and conclude, using the symbols and conventions of chemistry. Creativity is encouraged throughout this strand and students will discuss the problem of sustainability, exploring our world’s natural resources and how we can develop methods of sustaining our natural reserves and develop alternatives.
