About This Chapter
Who's it for?
This unit of our High School Physical Science Homeschool course will benefit any student who is trying to learn about the physical and chemical properties of matter. There is no faster or easier way to learn about matter. Among those who would benefit are:
- Students who require an efficient, self-paced course of study to learn states of matter, phase diagrams or phase equilibrium boundaries.
- Homeschool parents looking to spend less time preparing lessons and more time teaching.
- Homeschool parents who need a physical science curriculum that appeals to multiple learning types (visual or auditory).
- Gifted students and students with learning differences.
How it works:
- Students watch a short, fun video lesson that covers a specific unit topic.
- Students and parents can refer to the video transcripts to reinforce learning.
- Short quizzes and an Understanding Matter unit exam confirm understanding or identify any topics that require review.
Understanding Matter Unit Objectives:
- Find out how to classify different matter types.
- Describe solid, liquid and gas states of matter.
- Learn how to interpret phase diagrams and locate triple point and critical point.
- Understand uses for Avogadro's number.
- Study chemical change and common chemical reactions.
- Read about exothermic and endothermic reactions.
- Explore methods of separating mixtures, including distillation and chromatography.
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.
