Chemistry

Course summary

Chemistry is sometimes known as the ‘central science’ because it helps to connect physical sciences, like maths and physics, with applied sciences, like biology, medicine and engineering. Chemists conduct experiments to study how elements work in different conditions, test how they mix, and work out what they are made up of right down to the tiniest particle. The results can be ground-breaking, colourful, explosive, or almost impossible to see. Chemists use their experiments and knowledge to develop medicines, foods, fabrics and other materials, from neon lights to shatterproof glass. They also use it to understand the world around us, from why leaves change colour to discovering invisible pollutants in the air.
