Ch 1: Physical Science - Understanding Matter: Help and Review

About This Chapter

The Understanding Matter chapter of this High School Physical Science Help and Review course is the simplest way to master an understanding of matter. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of matter.

Who's it for?

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.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the Physical Science - Understanding Matter chapter exam.

Why it works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the Physical Science - Understanding Matter chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any question about matter. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Matter: Physical and Chemical Properties

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.

States of Matter: Solids, Liquids, Gases, & Plasma

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.

The Kinetic Molecular Theory: Properties of Solids and Liquids

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.

Phase Diagrams: Critical Point, Triple Point and Phase Equilibrium Boundaries

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.

Phase Change: Evaporation, Condensation, Freezing, Melting, Sublimation & Deposition

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.

Common Chemical Reactions and Energy Change

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.

Avogadro's Number: Using the Mole to Count Atoms

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.

Endothermic and Exothermic Reactions

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.

Chromatography, Distillation and Filtration: Methods of Separating Mixtures

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.
