This is a one year science course primarily for 7th graders, 6th graders who are strong academically, or 8th graders who need to strengthen their science background. It usually takes two weeks to cover a module. There are 16 modules. Some topics include: Scientific method, designing experiments, simple machines, archaeology, geology, paleontology, biology, and human anatomy and physiology. I especially like the section on historical science that discusses tests that show the validity of the Bible as an authentic historical work and support its trustworthiness.
