Switched-On Online Science is an exciting, Bible-based curriculum for grades 3-12. Students develop observational skills as they study the physical universe God created. The program involves a combination of on- and off-computer assignments including experiments. Elementary and middle-school grades (3-9) observe each area of science on an individual survey basis, usually unit by unit. The high school grades (10-12) focus on specific areas of science— Biology, Chemistry, and Physics. The four major strands are as follows: Life Science (Plants and Animals, Human Anatomy and Personal Care, Biology), Space and Earth Science (Geology, Weather, Space), Physical Science (Chemistry, Physics), Nature of Science (Scientific Method, Experimentation, Technology.)
