Grade 8 Science

Course Details:

Grade 8 Science (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 (Grade 6 Science, Grade 7 Science), including the disciplines of life science, physical science, and earth-space science. In addition, technology, engineering, and mathematics (STEM) concepts are integrated throughout the course. Students learn about 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 will be practicing, experimenting, thinking, and talking like a scientist!
