Ch 2: Structure of Matter: Help and Review

About This Chapter

The Structure of Matter chapter of this Middle School Physical Science Help and Review course is the simplest way to master matter's composition. 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 the structure of matter.

Who's it for?

Anyone who needs help learning or mastering middle school physical science material will benefit from taking this course. There is no faster or easier way to learn middle school physical science. Among those who would benefit are:

  • Students who have fallen behind in understanding components and properties of matter
  • 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 the structure of 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 Structure of 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 Structure of Matter chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any question about the structure of matter. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Students will review:

8 Lessons in Chapter 2: Structure of Matter: Help and Review
Test your knowledge with a 30-question chapter practice test
What is An Atom? - Definition & Examples

1. What is An Atom? - Definition & Examples

After watching this video, you will be able to explain what an atom is, how it is structured, what they are made from, and give some examples of elements. A short quiz will follow.

What Are Elements?

2. What Are Elements?

Look around you. What do you see? Elements are everywhere. They are the building blocks of all matter on Earth. In this lesson, we will discuss what an element is, how elements are written as symbols, and how elements are the building blocks of all matter.

What Is a Compound? - Combining Elements with Chemical Bonds

3. What Is a Compound? - Combining Elements with Chemical Bonds

After watching this video, you will be able to explain what a compound is, identify compounds versus regular molecules, and describe the two types of bonding that form compounds. A short quiz will follow.

How Compounds and Molecules Are Built From Elements

4. How Compounds and Molecules Are Built From Elements

Did you know that elements are like people and have different personalities? A few elements are very shy and love to be left alone. Others are very social and prefer to hang out with friends. In this lesson we will discuss how elements build molecules and compounds.

How Atoms & Molecules Form Solids: Patterns & Crystals

5. How Atoms & Molecules Form Solids: Patterns & Crystals

After watching this video, you will be able to explain how atoms and molecules form solids, whether in the form of random mixtures or crystal patterns. A short quiz will follow.

Matter: Physical and Chemical Properties

6. 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

7. 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.

States of Matter and Chemical Versus Physical Changes to Matter

8. States of Matter and Chemical Versus Physical Changes to Matter

The world around us is constantly changing. Chemists put those changes into two main categories: physical changes and chemical changes. This lesson will define and provide examples of each.
