The History and Nature of Science - Chapter Summary
Use the fun video and text lessons in this chapter to explore the nature of science and the history of several scientific fields. Our instructors explain exactly what science is and address key concepts including scientific theories and laws. You'll also review the backgrounds and branches of a number of fields, including chemistry, physics, life sciences and more. Once you've reviewed the chapter's materials you should feel comfortable:
- Defining earth science
- Listing the branches of life sciences
- Discussing the origins of chemistry
- Identifying geology's three main subdivisions
- Describing the history and branches of physics
- Listing the specialized fields within astronomy
- Explaining how biological theories are developed
- Discussing major events in biology's history
We make studying science a simply and entertaining activity. Our brief video lessons are taught by expert instructors and feature visuals and examples. They also include tags so you can go back and re-watch excerpts during study time. We provide video transcripts that commonly have links to other helpful text lessons. You can assess your comprehension of this chapter's topics by taking the multiple-choice lesson quizzes.
1. The Nature of Science
This lesson will explore the basic nature of science. It will distinguish science from pseudoscience and hypothesis from theory and natural law; it will give plenty of examples of each.
2. What is Earth Science?
Earth science is a field that includes geology, astronomy, meteorology, and oceanography. Scientists do research in these fields to discover past and future events. Learn about the dynamic field of earth science and how it affects our lives in this lesson.
3. What Are Life Sciences?
The life sciences study all types of living things. Branches of the life science study things from the tiniest microorganisms to the largest animals. Learn about the many branches of the life sciences and what it's like to work in these fields.
4. Life Science Theories
In the life sciences there are many theories that explain how life works. However, before these theories became widely accepted, they had to be put to the test. In this lesson, you will learn how ideas become theories.
5. 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.
6. 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.
7. 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.
8. The Scientific Field of Astronomy
Space is a large and exciting place, full of things we have yet to discover. Astronomy aims to uncover the mysteries of space, something people have been fascinated with as long as they have been on Earth.
9. How Biological Theories Develop
The process of developing scientific theories is a crucial part of understanding the natural world. Here we will examine how biological theories develop. At the end, you can test your knowledge with a brief quiz.
10. Key Events in the History of Biological Study
The study of living things has a rich and exciting history. Here we will examine some of the key events in the history of biological study, their significance to the field, and the impacts of biological discoveries on humankind. At the end, you can test your knowledge with a brief quiz.
