Middle School Comprehensive Science 3 is the third in a series of three consecutive middle school science classes. It builds on concepts introduced in the first and second courses of the series, including the disciplines of life science, physical science, and earth-space science. In addition, technology, engineering, and mathematics (STEM) concepts, as well as various biblical and theological ideas, are integrated throughout the course. Students learn about the relationship between science and Christianity, properties of matter, physical and chemical changes, atoms and the periodic table of elements, photosynthesis and cellular respiration, the universe, and the solar system. Hands-on and virtual laboratory investigations are included throughout the course to provide students opportunities for exploration through scientific inquiry, research, measurement, problem-solving, and experimental procedures. By the end of the course, students are practicing, experimenting, thinking, and talking like scientists—all in light of a Christian worldview.
