Anyone who needs help learning or mastering high school physical science material will benefit from taking this course. There is no faster or easier way to learn high school physical science. Among those who would benefit are:
- Students who have fallen behind in understanding the chemical and physical properties of matter, including solids and liquids
- Students who struggle with learning disabilities or learning differences, including autism and ADHD
- Students who prefer multiple ways of learning science (visual or auditory)
- Students who have missed class time and need to catch up
- Students who need an efficient way to learn about matter
- Students who struggle to understand their teachers
- Students who attend schools without extra science learning resources
How it works:
- Find videos in our course that cover what you need to learn or review.

Students will review:
This chapter helps students review the concepts in an understanding matter unit of a standard high school physical science course. Topics covered include:
- States of matter
- The kinetic molecular theory
- Phase diagrams
- Phase change
- Chemical reactions and energy change
- Avogadro's number
- Exothermic and endothermic reactions
- Chromatography, distillation and filtration
1. Matter: Physical and Chemical Properties
How are substances identified? There are two major ways we can describe a substance: physical properties and chemical properties. Learn about how chemists use properties to classify matter as either a mixture or a pure substance.
2. States of Matter: Solids, Liquids, Gases, & Plasma
Learn the four states of matter in the universe: solid, liquid, gas and plasma. Learn about the differences in shape and volume among the four states, which of the states is the most common and why plasma conducts electricity.
3. The Kinetic Molecular Theory: Properties of Solids and Liquids
This lesson explores the kinetic molecular theory and how it pertains to the properties of solids and liquids. You'll learn the properties of solids and liquids, discover the types of intermolecular attractions that occur between them and gain an understanding how phase changes happen.
4. Phase Diagrams: Critical Point, Triple Point and Phase Equilibrium Boundaries
Learn what a phase diagram is and how to interpret phase diagrams. Discover how to use a phase diagram to locate the phase equilibrium boundaries. Also, learn what a triple point and critical point are and how to locate them on a phase diagram.
5. Phase Change: Evaporation, Condensation, Freezing, Melting, Sublimation & Deposition
Substances on Earth can exist in one of four phases, but mostly, they exist in one of three: solid, liquid or gas. Learn the six changes of phase: freezing, melting, condensation, vaporization, sublimation and deposition.
6. Common Chemical Reactions and Energy Change
This lesson covers the five common types of chemical reactions: combination, decomposition, single-replacement, double-replacement, and combustion. You will learn how to predict what kind of chemical reaction will occur. You'll also explore how matter is conserved, but energy can change.
7. Avogadro's Number: Using the Mole to Count Atoms
How do we move from the atomic world to the regular world? Because atoms are so tiny, how can we count and measure them? And what do chemists celebrate at 6:02 AM on October 23rd each year? In this lesson, you will be learning how Avogadro's number and the mole can answer these questions.
8. Endothermic and Exothermic Reactions
Explore a chemical reaction at the molecular level. Learn about exothermic and endothermic reactions, what they look like and what happens when they occur. Understand enthalpy and how you can use it to predict whether a reaction will be exothermic or endothermic.
9. Chromatography, Distillation and Filtration: Methods of Separating Mixtures
What are some ways that mixtures can be separated? Watch this video to explore several examples of ways you can separate a mixture into its individual components.
