Study Notes
Chemistry is a scientific discipline that studies matter and how it changes. It explores elements, compounds, mixtures and reactions. Atoms combine together to form molecules which can bond with other atoms forming chemical bonds between them. These molecular structures can react or change into different forms of energy, like light, heat or movement. This is called a reaction. Chemists use their knowledge of chemistry to create new materials or solve problems in society. For example, chemists have invented medicines by understanding how chemicals affect our body's cells. They also make plastics from oil and gas. Chemicals are everywhere! From the paint on your walls, to the pencils you use, everything in our world has been made using chemistry.
