Grade 8 - Science

Physical Science B - Semester 2 (Credit: 0.50)

Science is the study of the natural world. It relies on experimentation and evidence to describe the natural events that occur around us. Physical science is the study of matter and energy. In Physical Science B, you’ll investigate gravitational, electric, and magnetic force fields and identify factors that determine their strength. You’ll apply concepts of electricity and magnetism to explain how motors, generators, and electromagnets work. You will discuss energy transformations in objects and systems, including how heat flows between objects that are at different temperatures. You will model how sound and light travel as waves and how they interact with different forms of matter. Finally, you’ll explore how electromagnetic waves help us communicate with one another and collect information about the universe.
