Ch 11: General Science: Energy & Matter

About This Chapter

In the state of Arizona, the AEPA General Science exam is used as a basis for verifying the competencies of aspiring teachers. This study guide will help you review energy, matter and related topics you'll need to know for the AEPA General Science exam.

AEPA General Science: Energy & Matter - Chapter Summary

In this chapter on energy and matter, you'll learn about temperature, energy types and cycles of matter. By the end of the chapter, you will be proficient in the following areas covered by the AEPA General Science test:

  • Energy conservation and the law of conservation of matter
  • Kinetic and potential energy
  • Various kinds of energy conversions
  • Chemical and physical properties of matter
  • Temperature units and converting between them
  • Mechanisms of heat transfer
  • The carbon and nitrogen cycles
  • Convection currents
  • How energy is transformed in living organisms

Use these engaging video lessons to fill in knowledge gaps and review topics you haven't covered in a while. Each lesson comes with a full written transcript, so you can follow along while you're watching the videos or skim through to get a gist of the topics covered. Lessons are followed by an assessment quiz that you can use to test your knowledge.

AEPA General Science: Energy & Matter Objectives

This chapter on energy and matter is designed to help you study for the physical science portion of the AEPA General Science exam. Among other topics, the questions in this section will test your understanding of energy transformation in chemical and physical systems. You'll need to be able to analyze phase diagrams, phase changes, and cooling and heating curves.

The AEPA General Science test is a requirement to teach science in Arizona. The test contains 150 multiple-choice questions and lasts three hours. Questions on physical science topics make up about 37% of the test. Use the practice quizzes in this chapter to make sure you are ready for the questions on energy and matter.

Test your knowledge with a 30-question chapter practice test
What is Energy Conservation? - Definition, Process & Examples

1. What is Energy Conservation? - Definition, Process & Examples

This lesson will explain what the conservation of energy principle is and why it matters, using some real-life examples of how it works in our day-to-day lives. A short quiz will follow.

Law of Conservation of Matter: Definition & Matter

2. Law of Conservation of Matter: Definition & Matter

In this lesson, we'll learn the definition of the Law of Conservation of Mass, sometimes called the Conservation of Matter. This lesson explores the discovery of this important principle and covers a few examples of how it works.

Kinetic Energy to Potential Energy: Relationship in Different Energy Types

3. Kinetic Energy to Potential Energy: Relationship in Different Energy Types

This video defines and describes kinetic and potential energy. You'll learn how different types of energy can be classified as potential and kinetic. You'll also find out how kinetic and potential energy are transformed.

Matter: Physical and Chemical Properties

4. 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.

What is Temperature? - Definition & Measurement

5. What is Temperature? - Definition & Measurement

In the most intuitive terms, temperature refers to how hot or cold something is. Learn more about temperature as a measure of the average kinetic energy of the particles in an object and test your knowledge with quiz questions.

Degrees Fahrenheit: Definition & Conversion

6. Degrees Fahrenheit: Definition & Conversion

In this lesson, we will define the degree and the Fahrenheit temperature scale. We will also compare the Fahrenheit scale to the other temperature scales and learn how to convert between them.

Temperature Units: Converting Between Kelvins and Celsius

7. Temperature Units: Converting Between Kelvins and Celsius

Have you ever wondered what the lowest possible temperature is? In this lesson, you will learn what temperature measures. You will also be introduced to the Kelvin scale (an absolute scale) and learn how it relates to the Celsius scale.

Mechanisms of Heat Transfer: Conduction, Convection & Radiation

8. Mechanisms of Heat Transfer: Conduction, Convection & Radiation

There are three main ways that heat is transferred between substances or objects. In this video lesson you'll learn about each one, and identify the differences between them.

Cycles of Matter: The Nitrogen Cycle and the Carbon Cycle

9. Cycles of Matter: The Nitrogen Cycle and the Carbon Cycle

Matter is constantly cycled between living and nonliving parts of the environment. Processes like photosynthesis and nitrogen fixation allow the carbon and nitrogen cycles to regenerate needed substances by recycling Earth's atoms.

What are Convection Currents? - Definition & Examples

10. What are Convection Currents? - Definition & Examples

This lesson will define convection, explain how it works, and describe how convection creates currents. We will also go through some examples of convection in the world around us: campfires, weather systems, and convection in the earth's mantle.

Energy and Life: The Transformation of Energy in Living Organisms

11. Energy and Life: The Transformation of Energy in Living Organisms

While the sun is an excellent source of energy, not all forms of life can utilize the sun's energy directly. This lesson describes how plants transform the sun's energy into potential energy stored in sugar, how living organisms utilize energy in sugar to perform work, and how the relationship between photosynthesis and cellular respiration is necessary for life.

Types of Energy Conversions

12. Types of Energy Conversions

After completing this lesson, you will be able to explain what energy is and what we mean when we say energy is 'conserved,' and give some examples of conversions between different types of energy.
