Understanding Physical Science

(updated 17 March 2023)

Physical Science is concerned with the study of non-living objects and systems. This includes the study of matter and its interactions, from the very small atomic level to the massive interactions of galaxies in the universe.

Physical Science consists of the studies of Physics, Chemistry, Astronomy and Earth Science. It also includes scientific method, measurement and experimentation. Physics is the fundamental science that states the rules and laws of matter and energy; the other physical sciences apply those rules on a larger scale.

The purpose of these online lessons is to give you a start at improving your scientific knowledge that will help you become a champion in the field.
