Gain a solid foundation in chemistry and earn credit toward high school graduation. This convenient online course gives you the chance to work at your own pace while you complete your first semester of chemistry study.

In this course, you'll examine the building blocks of matter and learn how atoms and molecules make up the world around you. From the composition of the atom to the periodic table, this course includes everything you need to know about the composition, properties, and changes associated with matter and their applications. In Semester 1, you'll study fundamental topics of chemistry, including:

  • Matter and the elements
  • Chemical bonds and molecular structure
  • The conservation of matter
  • Chemical thermodynamics
  • Chemical reactions
  • Stoichiometry

Because this course is taught online, you'll be able to work at your own pace. From start to finish, a dedicated and experienced instructor will be available to guide your learning and answer all your questions. It's a flexible, convenient way to complete your science requirement for high school graduation.

This course is offered through Career Online High School, a division of Smart Horizons Career Online High School, and is accredited by the Southern Association of Colleges and Schools (SACS). Chemistry: Semester 1 is a one-semester course, and can be completed in up to four weeks. Once you complete Chemistry: Semester 1, you can continue your science education with the next offering in this series, Chemistry: Semester 2. Enroll in this convenient, affordable course, and start on your path toward completing your high school education.
