Chemistry

Chemistry is about understanding the properties of different substances and how these substances can change. Chemistry allows us to predict how substances may alter when the surrounding conditions change, or how they may react to form new substances, and to explain why this happens. Chemists are continually changing matter into new and more useful forms.

Chemical transformations happen all the time, everywhere. Chemistry goes on continuously, all around us; in plants that make food using the air and in animals that digest this food, in the burning of fuel and rusting of cars, in the formation of snow and ice, in the industries that supply us with all our household products, and in the many biological processes that maintain the living world.

Chemists interpret the world from an atomic perspective. 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.

Biology

Biology is the scientific study of living things. Life is incredibly varied, yet based on common processes. Biologists – and students studying biology – seek evidence to explain the nature of living things, and to understand where and how life is evolving, how evolution links life processes and ecology, and the impact that humans have on all forms of life.

Biology explores the interconnectedness of all living things and the environment. Through learning in biology, students discover that life involves interactions at all levels of organisation: cells interact with their environment and with each other, so do organs, organisms and ecosystems. No living thing exists in isolation from its environment.

Physics

Physics seeks to understand the basics. Physics seeks to understand nature at its most fundamental level. Physicists – and students studying physics – attempt to discover and apply the general laws that govern force and motion, matter and energy, and space and time.

Physics has a broad canvas. Physics seeks to discover the inner workings of nature in systems ranging in size from the smallest elementary particles such as quarks, protons, and neutrons to superclusters of galaxies.

Physics is both applied and theoretical. Physics explains the science that underlies the behaviour of everyday things such as cars and bridges as well as abstract things such as the curvature of space-time near a black hole.
