For K-8: Elemental Science provides lesson plans and teaching schedules, while relying on outside books (published by Usborne, DK and others) for the bulk of the science content. Elemental Science offers either a classical or living books approach to teaching science. Though the author is a Christian, she does not include a religious viewpoint in the materials. Elemental Science includes books that come from an evolutionary standpoint.
For high school: Elemental Science offer live online courses in biology and physical science. These courses are two semester courses which meet twice weekly (beginning in August and running through December and then picking up for the second semester in January) with a live teacher in a classroom and lecture/discussion time. The course also includes homework, quizzes, and tests which are graded and the student receives a semester course grade for their work.
