Ch 4: Praxis Earth & Space Sciences: Principles of Energy

About This Chapter

Let us reveal the principles and characteristics of energy. The videos and quizzes for each chapter's lesson can help you correctly approach the questions on the Earth and Space Sciences Praxis test.

Praxis Earth and Space Sciences: Principles of Energy - Chapter Summary

Complete this chapter's lessons to understand the principles of energy, including different energy types. The material presented in the lessons can help you prepare for the Earth and Space Sciences Praxis exam. Lessons provide instruction that can assist you in answering test questions that address:

  • Defining energy and its place in nature
  • Understanding common chemical reactions
  • Identifying different energy types, such as kinetic vs. potential energy
  • Telling the difference between energy conservation and energy efficiency
  • Understanding the ideal gas law
  • Applying the principles of nuclear chemistry to fusion, fission and carbon dating
  • Calculating the heat capacity for different substances
  • Converting between Kelvins and Celsius

Instructors explore these topics through short and engaging video lessons. Examples, summaries and self-assessment quizzes are provided to make sure that you've fully assimilated the lesson material and that you're ready to take the Praxis.

Praxis Earth and Space Sciences: Principles of Energy Objectives

The intent of the Earth and Space Sciences Praxis test is to determine your readiness to teach earth and space sciences subjects at the secondary school level. The test must be completed in two hours and consists of 100 multiple-choice questions. You may take the test on paper or on a computer.

The test may ask you about fundamental concepts, scientific principles and interrelationships on subjects that include oceanography, astronomy, environmental science, meteorology and geology. You will have to analyze and solve problems that may include graphs, charts and diagrams. Questions that cover the principles of energy are provided in the basic scientific principles of earth and space sciences section of the test, which accounts for 8-12% of the exam.

What is Energy? - Definition and Significance in Nature

1. What is Energy? - Definition and Significance in Nature

This lesson describes the nature of energy and how it is transferred from one source into another. Additionally, it will describe the significance of energy in natural systems.

Common Chemical Reactions and Energy Change

2. 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.

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.

Energy Conservation and Energy Efficiency: Examples and Differences

4. Energy Conservation and Energy Efficiency: Examples and Differences

Saving energy is an important topic, but energy conservation and energy efficiency are not the same thing. Learn what the difference is and some examples of both energy conservation and energy efficiency.

The Ideal Gas Law and the Gas Constant

5. The Ideal Gas Law and the Gas Constant

Have you ever wondered why the pressure in your car's tires is higher after you have been driving a while? In this lesson, we are going to discuss the law that governs ideal gases and is used to predict the behavior of real gases: the ideal gas law.

Fusion, Fission, Carbon Dating, Tracers & Imaging: Applications of Nuclear Chemistry

6. Fusion, Fission, Carbon Dating, Tracers & Imaging: Applications of Nuclear Chemistry

What can the sun do that we can't? How do carbon atoms 'date'? Are radioactive isotopes helpful in the medical field? The answers to these questions can be found in this lesson on the applications of nuclear chemistry.

Nuclear Reaction: Definition & Examples

7. Nuclear Reaction: Definition & Examples

Learn the differences between a nuclear reaction and a chemical reaction. Also learn how the nuclear reaction involves subatomic particles including protons and neutrons. Discover the different types of nuclear reactions including fission and fusion and also how a nuclear power plant works to produce energy.

How to Calculate Specific Heat Capacity for Different Substances

8. How to Calculate Specific Heat Capacity for Different Substances

This lesson describes specific heat capacity and explains how the specific heat capacity of water helps to maintain a relatively constant temperature in nature. Learn how to identify the specific heat capacity of other common materials and how to calculate specific heat capacity with an experiment.

Temperature Units: Converting Between Kelvins and Celsius

9. 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.
