If you ever wondered how the characters in CSI (Crime Scene Investigation) know so much, it probably starts with an understanding of Chemistry. Chemistry is the study of composition and substances, their properties and reactions; chemistry is the broadest of the science degree subjects, incorporating elements of biology and physics. Chemistry remains at the heart of science and our understanding of life.

Chemistry is also referred to as the central science because it connects physics with other natural sciences such as geology and biology. Chemistry examines the composition, structure, properties, and reactions of matter, all the elements of the universe. It looks at the way the material world--petroleum, a tree, your hand--is arranged. What are the properties that make water? What do we need to sustain life? How do two chemicals react with each other? These are some of the basic questions a chemistry student tries to answer.

While studying Chemistry, you will look at the nature and classifications of matter, such as atoms, elements, compounds and molecules; study concepts and theories, including the laws of chemistry, bonding and quantum chemistry; and learn about some of chemistry's famous names, such as Robert Boyle and John Dalton.

It is not an easy discipline; expect a lot of lab work and hours of research. However, you may expect to take away a firm foundation in chemical knowledge and the practical skills to go along with it.
