The Germ Theory of Disease: Definition & Louis Pasteur

1. 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 Origin of Life on Earth: Theories and Explanations

2. The Origin of Life on Earth: Theories and Explanations

Ever wonder how living things came from non-living things? We will explore what conditions on early Earth may have created life from non-living items.

Methods of Geological Dating: Numerical and Relative Dating

3. Methods of Geological Dating: Numerical and Relative Dating

Learn how scientists determine the ages of rocks and fossils. We'll explore both relative and numerical dating on our quest to understand the process of geological dating. Along the way, we'll learn how stratigraphic succession and radioactive decay contribute to the work of paleontologists.

Relative Dating with Fossils: Index Fossils as Indicators of Time

4. Relative Dating with Fossils: Index Fossils as Indicators of Time

You may already know how to date a fossil with a rock. But did you know that we can also date a rock with a fossil? Watch this video to find out how we use index fossils to establish the relative ages of rocks.

Radiometric Dating: Methods, Uses & the Significance of Half-Life

5. Radiometric Dating: Methods, Uses & the Significance of Half-Life

Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes. Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson.

Role of RNA Molecules: Definition & Functions

6. Role of RNA Molecules: Definition & Functions

DNA gets all of the glory, but RNA is equally important. This lesson will examine RNA's role in protein synthesis, as well as its ability to act as an enzyme.

The Evolution of Prokaryotes: Archaebacteria and Eubacteria

7. The Evolution of Prokaryotes: Archaebacteria and Eubacteria

The first living organisms on Earth were bacteria. These small organisms still exist today and are responsible for many things. In this lesson, we will explore both ancient bacteria and true bacteria.

Cyanobacteria: Definition, Characteristics & Species

8. Cyanobacteria: Definition, Characteristics & Species

Cyanobacteria are a phylum of Bacteria that produce oxygen during photosynthesis. This lesson will examine cyanobacteria and the role they played in establishing our oxygen-rich atmosphere.

The Endosymbiosis Theory: Evolution of Cells

9. The Endosymbiosis Theory: Evolution of Cells

Ever wonder why some cells are very simple and others are complex with countless organelles to remember? We will look at how simple cells evolved to become more complex cells - as well as evidence to support this.
