Why Study Chemistry?

Chemistry, the study of matter and energy and their transformations, helps us understand the physical world and our impact on it. Chemistry answers questions like:

  • Why does ice float? 
  • Where do the colors in fireworks come from? 
  • How do electric cars work? Explore a fuel cell.
  • What do lumber and pasta have in common?

Enroll in chemistry classes to begin working toward an associate’s degree in Biotechnology or Molecular Biosciences, or to finish general science requirements before transferring to a bachelor’s degree program.
