13 Lessons in Chapter 1: Holt Physical Science Chapter 1: The World of Physical Science
The Main Branches and Sub-Branches of Physical Science

1. The Main Branches and Sub-Branches of Physical Science

The physical sciences study non-living things. That is a lot of stuff! In the physical sciences, you might study the earth, air or space. Learn about the two main branches, physics and chemistry, as well as sub-branches, like geology and meteorology.

What is Physics? - Definition, History & Branches

2. 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.

What is Chemistry? - Definition, History & Branches

3. What is Chemistry? - Definition, History & Branches

Known as the central science, chemistry is integral to our understanding of the natural world around us. In this lesson, you'll be introduced to the field of chemistry, learning about its history and its modern applications.

The Scientific Field of Meteorology

4. The Scientific Field of Meteorology

Thanks to meteorologists, we can plan for both short- and long-term weather events that affect our daily lives. But meteorology has been around a lot longer than the daily news, and this scientific field helps us better understand the world around us in a many ways.

The Main Branches of Geology

5. The Main Branches of Geology

Although many people think the field of geology focuses solely on rocks, there is much more behind this scientific field. Geology has many different branches that each focus on interesting and unique features of our planet and beyond.

The Scientific Method: Steps, Terms & Examples

6. 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

7. 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.

Experimental Design in Science: Definition & Method

8. Experimental Design in Science: Definition & Method

What are the requirements of a scientific experiment? How do scientists turn hypotheses into theories and laws? Learn the answers to these questions and more in this lesson on the design of scientific experiments.

Hypothesis Testing: Comparing the Null & Alternative Hypothesis

9. 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.

How to Read Scientific Graphs & Charts

10. How to Read Scientific Graphs & Charts

How do scientists summarize their findings with visual aids? In this lesson, explore the different types of tables, charts and graphs that scientists use. Learn to read these effectively as a preview to your science studies.

What is the Metric System?

11. What is the Metric System?

Most of the world relies on the metric system for measuring distance, weight, volume, and time. Watch this video lesson to learn what kinds of measurements are used in the metric system.

Scientific Tools and Their Uses

12. Scientific Tools and Their Uses

A scientist relies on tools to help make observations, carry out experiments and take measurements. Learn about the scientific tools used in a lab and the advanced tools used by scientists in the life sciences.

Laboratory Safety Techniques: Protecting People and Equipment

13. Laboratory Safety Techniques: Protecting People and Equipment

Laboratory safety is not fun, but following the rules ensures that lab activities can be enjoyed by everyone. In this lesson, we cover some basic lab safety rules to follow that will help lab time be both safe and fun.
