Ch 1: Holt McDougal Physics Chapter 1: The Science of Physics

About This Chapter

The Science of Physics chapter of this Holt McDougal Physics Companion Course helps students learn the essential lessons associated with the science of physics. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Science of Physics textbook chapter.

How It Works:

  • Identify the lessons in the Holt McDougal Science of Physics chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the science of physics topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Definition, history and branches of physics
  • Examples, terms and steps of the scientific method
  • Process of developing the scientific hypothesis
  • How to test hypotheses
  • Independent and dependent variables
  • Units and conversion of the metric system
  • Scientific notation and significant figures
  • How to organize and understand data in schedules and tables
  • Ways to construct graphs from data

What is Physics? - Definition, History & Branches

1. What is Physics? - Definition, History & Branches

Known as the fundamental science, physics creates a foundation for other natural sciences. In this lesson, you'll be introduced to the field of physics, learning about its history and its modern branches of study.

The Scientific Method: Steps, Terms & Examples

2. The Scientific Method: Steps, Terms & Examples

The scientific method is more than just hypotheses and experiments. In this lesson, we'll explore the themes and variations that make up the world of science.

Developing a Scientific Hypothesis

3. Developing a Scientific Hypothesis

This video describes how to create a hypothesis and includes the three main things needed to create a strong hypothesis. You'll learn how to make a clear statement that can be both tested and measured.

Hypothesis Testing: Comparing the Null & Alternative Hypothesis

4. Hypothesis Testing: Comparing the Null & Alternative Hypothesis

This lesson explores the process of comparing the null and the alternative hypothesis, as well as how to differentiate between the two after your testing is done.

Identifying & Interpreting Independent & Dependent Variables

5. Identifying & Interpreting Independent & Dependent Variables

Scientists answer questions by performing experiments that have an independent variable, a dependent variable and at least one control variable. By controlling, adjusting and measuring these variables, scientists find answers to their questions.

The Metric System: Units and Conversion

6. The Metric System: Units and Conversion

Just like you and your friend communicate using the same language, scientists all over the world need to use the same language when reporting the measurements they make. This language is called the metric system. In this lesson we will cover the metric units for length, mass, volume, density and temperature, and also discuss how to convert among them.

Significant Figures and Scientific Notation

7. Significant Figures and Scientific Notation

Are 7.5 grams and 7.50 grams the same? How do scientists represent very large and very small quantities? Find out the answers to these questions in this video.

Organizing and Understanding Data with Tables & Schedules

8. Organizing and Understanding Data with Tables & Schedules

In math, when we have to deal with a lot of data, having a visual format to present all the data becomes very useful. Watch this video lesson to learn how you can take advantage of two of these visual formats.

How to Construct Graphs from Data

9. How to Construct Graphs from Data

This video describes how to create a line graph and explains the four main parts that graphs need to contain: 1. previously collected data, 2. picture representations, 3. use of the correct graph type, and 4. labels. This lesson also covers dependent and independent variables.
