Physical Science is a broad field that covers the non-living aspects of the world, including both chemistry and physics. Physical science looks at the basic structure of things and the different ways that objects interact with each other. Physical Science A reviews the scientific process and then moves on to cover the basics of chemistry including the properties of matter, the periodic table and how chemicals react. The last lesson of every unit of this course is devoted to engineering and how the information that you have learned can be applied.
