Praxis Biology & General Science: Objectives

The Praxis Biology & General Science exam is used to determine your readiness to be licensed as a science/biology teacher in your state. Please note, the exact requirements for licensing or certification, including the minimum score you'll need to be eligible, vary by state.

For this exam, you'll have to:

  • Understand the connections between science, technology, and applications in society
  • Apply scientific principles and theories to common scenarios
  • Be able to interpret scientific data collected in the field and observed in the laboratory

The Biology & General Science test consists of 120 multiple-choice questions. Physics accounts for about ten percent of the exam - about 12 questions.

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.

Kinetic Energy to Potential Energy: Relationship in Different Energy Types

2. 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.

First Law of Thermodynamics: Law of Conservation of Energy

3. First Law of Thermodynamics: Law of Conservation of Energy

This video describes the first law of thermodynamics. Several examples of the application of this law are discussed. The significance of the law and its practical application are discussed as well.

Second Law of Thermodynamics: Entropy and Systems

4. Second Law of Thermodynamics: Entropy and Systems

In this lesson, we'll learn about the second law of thermodynamics. By studying this law, you'll understand how energy works and why we're all moving towards eventual chaos and disorder.

What is Mechanical Energy? - Definition & Examples

5. What is Mechanical Energy? - Definition & Examples

In physics, energy is how work gets done. This video describes one important type of energy, mechanical energy, and provides examples of both kinetic and potential mechanical energy.

What is Thermal Energy? - Definition & Examples

6. What is Thermal Energy? - Definition & Examples

This lesson defines and identifies examples of thermal energy everywhere from your kitchen to the Earth's core. We'll discuss geothermal energy, a renewable energy source, as well.

What is Radiant Energy? - Definition & Examples

7. What is Radiant Energy? - Definition & Examples

This lesson defines and describes radiant energy in its different forms. The different types of electromagnetic waves created by radiant energy are identified and described as well. This includes X-rays, microwaves, and radio waves, to mention a few.

What is Chemical Energy? - Definition & Examples

8. What is Chemical Energy? - Definition & Examples

This lesson describes chemical energy as a type of potential energy stored in chemicals, such as sugar and gasoline. The lesson discusses how energy is transferred from solar energy to chemical energy by plants and how gasoline is a source of chemical energy used to move cars.

What is Electrical Energy? - Definition & Examples

9. What is Electrical Energy? - Definition & Examples

This lesson defines electrical energy and explores its role as a form of potential energy. It also offers an explanation of how it functions within electric fields and provides examples of its applications.

How to Calculate Specific Heat Capacity for Different Substances

10. 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.

Changes in Heat and Energy Diagrams

11. Changes in Heat and Energy Diagrams

Did you know that temperature and heat are not the same thing? Did you know that the temperature of water doesn't change when it boils? This lesson describes the relationship between heat and temperature. Diagrams are used to illustrate the relationship between heat and temperature during phase changes.

Energy and Life: The Transformation of Energy in Living Organisms

12. 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.
