States of Matter and Changes of State is a foundational course designed to make the invisible world of particles come alive. Everything around us—whether it’s the air we breathe, the water we drink, or the materials we build with—exists in one of several physical forms.
These forms, known as the states of matter, behave in distinct ways depending on how their particles are arranged and how much energy they carry. In this course, you’ll explore solids, liquids, gases, and plasma, and discover how matter transitions between these states through everyday processes like melting, boiling, and condensation.
Whether you’re curious about why ice melts or how clouds form, this course will give you the tools to understand the science behind it all.
By the end of the course, you’ll be able to clearly identify the four main states of matter and explain how energy drives their transformations. You’ll understand the difference between physical and chemical changes, and how to spot them in real-world scenarios.
From dissolving sugar in water to baking a cake, you’ll learn to distinguish changes that alter appearance from those that create entirely new substances. This knowledge lays the groundwork for deeper studies in chemistry, physics, and environmental science.
This course is ideal for learners who want to build a strong foundation in physical science. Whether you’re a student, educator, or simply someone with a curious mind, you’ll find this course engaging and accessible
