The Natural Sciences Department encompasses the fields of biology, environmental science, chemistry, and physics. We provide a solid foundation to continue in biology, chemistry, environmental science, or any medical or engineering field. From pre-pharmacy, pre-med, or pre-engineering, we are a great place to start.

About Our Programs


Learn the foundation for understanding organisms, including their origin, evolution, characteristics, and interaction with their environment. Students examine biological processes at various levels of organizations such as molecular, cellular, organismal, and ecological. 

Biology - A.S. Program Page


Learn a foundation for the field of chemistry through introductory inorganic and organic courses. Study includes atomic and molecular structures, orbital theory, chemical reactions, stoichiometry, and chemical equations.

Chemistry - A.S. Program Page


Physics promotes critical thinking and problem-solving skills and explains how things work in our natural world. Data from the American Institute of Physics show that physics majors get among the highest scores in the Medical College Admission Test (MCAT) and the Law School Admission Test (LSAT) of all the undergraduate majors.


Explore the mysteries of the universe, such as the birth and evolution of stars, planets, galaxies, and the formation of matter, to improve life and technology on Earth.


The Natural Sciences Department prepares students for careers in a variety of industries, including:

  • Engineering fields (electrical, civil, mechanical, computer, aerospace, etc.).
  • Fiber optics.
  • Physics.
  • Pharmacy.
  • Radiology.
  • Physical therapy.
  • Nanotechnology.
  • Aviation.
  • Energy and renewable energy.
