Do you ever wonder why the Grand Canyon is so big, or why the moon changes shape? Physical Science can answer these questions and more because it explores the science behind nonliving things. As a broad scientific topic, Physical Science provides information about the geology of the Grand Canyon and the moon's orbital behavior. Nonliving objects impact our living environment for better and worse, so learning about the Forces, Heat and Motion of these elements will help you appreciate and possibly protect the world in which you live. Take it a bit further and explore the Properties of Matter and how Waves of Energy are surrounding you at all times. Get to know the world you live in by studying the Physical Sciences.
