About This Chapter
GED Science: Physical Science - Chapter Summary
Jump into your study sessions about physical science for the GED exam's science section with brief lessons in this chapter that include topics like the effects of a chemical reaction, various kinds of energy, and more. You will also study these subjects:
- Definition of and differences between atoms and molecules
- States of matter, including solids and gases
- Difference between chemical and physical changes to matter
- Newton's laws of motion
- Relationship between electricity and magnetism
After viewing the lessons, take the quizzes to test your memory of the information you reviewed. Print out the worksheets if you would like to quiz yourself while you're not near your mobile device. Complete the chapter by working at your own pace.
1. What are Atoms & Molecules? - Definition & Differences
There are lots of terms in chemistry that can be easy to mix up: atoms, molecules, compounds, mixtures, and more. In this lesson, we'll go through some of the basics of atoms and molecules, and define all of the important terms you need to know.
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. 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.
4. What Is a Chemical Reaction? - Definition & Effects
Sometimes, molecules look different on the outside, but only their physical appearance has changed. Other times, through chemical reactions, molecules change both inside and out, meaning both their physical and chemical properties have changed.
5. What are the Different Types of Energy?
Energy is one of the most fundamental concepts in many scientific fields. Learn more about its different types, subsequently testing your knowledge with a quiz.
6. Newton's Laws of Force & Motion
Newton's laws of motion explain why we observe the motion we do in the world around us -- they explain how forces work. In this lesson, we take a look at each of Newton's laws one by one.
7. Electricity & Magnetism: Definition & Relationship
Electricity and magnetism are two things that seem different, but actually have a lot in common. In this lesson, we'll define each of them, and then explore how they are really part of the same fundamental force of nature.
