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.

How Biological Theories Develop

2. 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.

Key Events in the History of Biological Study

3. 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.

The Germ Theory of Disease: Definition & Louis Pasteur

4. The Germ Theory of Disease: Definition & Louis Pasteur

In this lesson, we will look at one of the most influential experiments in the field of microbiology. We will learn how Louis Pasteur disproved the theory of spontaneous generation which helped lead to the development of the germ theory of disease.

The Development of Cell Theory

5. The Development of Cell Theory

Cell theory is a fundamental theory in biology that makes generalizations about cells. In this lesson, you'll learn about the development of modern cell theory and the scientists behind it.

Developments in Heredity, Evolution & Ecology
