Department of Physical science

Physical science is the study of non-living things, like matter, energy, space and time. As you can see, this is a big topic. In fact, you could say that whenever you question any non-living aspect of Earth, Earth's atmosphere or space, you are investigating the field of physical science.

Because physical science is such a broad topic, we can break it into branches. In this lesson, we will learn about the two main branches of physical science, namely physics and chemistry, as well as a few sub-branches..

Physics is the branch of physical science that studies matter and energy.

Chemistry is the branch of physical science that studies the substances that make up matter and how matter changes.
