Scientists believe RNA is the origin of all life on Earth, carrying genetic information long before DNA developed. Viewers comprehend this idea as they learn the functions of RNA, DNA, and proteins. Evolution of RNA, cells, molecules,...

Life existed on Earth more than four billion years ago, much earlier than scientists predicted. Eons presents a lively video as part of a larger series. It explains the recent findings on multiple continents that alter the timeline of...

Tardigrades are microscopic organisms (0.5 mm long) with segmented bodies and four pairs of legs, each with four to eight claws. The narrator of this video explores tardigrades, organisms that can survive the most extreme environments...

Charles Darwin's work, On The Origin of Species, fundamentally changed the study of science. Using clips from an author talk, young historians connect the scientific ideas behind evolution to American history. Afterward, they consider:...

Can we really grasp how old we are? Part of a larger series, the humorous video demonstration shows how humans fit into the history of Earth and just how long ago life formed. Viewers explore a timeline that identifies major markers in...

Aristotle explained the idea of spontaneous generation, a concept which lasted almost 2,000 years before scientists proved it wrong. Scholars learn about the history of our understanding of the origins of life. They read examples of...

Just when you thought you had life figured out ... here comes another great video! Young biologists discover the multi-faceted meaning of life through a video from a comprehensive science playlist. Content includes when life appeared on...

Care to speculate on how life on Earth came to be? The video presentation from the ACS Reaction series considers the possibility of comets creating the right conditions for the formation of life. Scholars consider colliding comets as...

Scientists try to understand the origins of life, and answers to these questions might be found during our lifetime. The fourth video in a 16-part series explains the earliest forms of life on Earth and their development. It covers...

The narrator of a short video explores carbon and why it is the basis for all life on Earth and discusses all elements necessary for life that can be found in the human body. 

Guess where the oldest rocks on Earth are found? And what do these rocks reveal about the age of the earth?   Viewers of this short video analyze the age of the earth and explore the origin of life through geologic, chemical, and...

Scholars explore how life on Earth formed more than 3.8 billion years ago through natural processes, from monomers to more complex organisms such as cells and then life. Viewers see the Miller-Urey experiment and how it supports this...

For thousands of years people have observed comets as they pass through the solar system, but could there be more to these celestial bodies than meets the eye? Watch this video to learn how these objects have recently been found to...

Conclude the examination of life on Earth with the last episode in this series on the origins of life. Part five uncovers the fossilized evidence that began building the human family tree in a whole new way. From the origins of...

In part two of the "Origin and Evolution of Life," our host looks to the hot geysers found in Yellowstone to show the type of environment primordial life may have evolved from. This leads to an explanation of how scientist Stanley Miller...

Continue your exploration of the origin of life with part three of this wonderful five-part series. This episode examines Precambrian fossils found in the Berges Shale. Watch this video to find out the value of this discovery to...

In part four of this five-part series on the origin of life on Earth, we learn about Charles Darwin and how he developed the theory of evolution. The focus of this video is looking at the evidence that Darwin observed. Perfect for...

Start a class exploration explaining the origin of evolution and life on planet Earth with the first of a five part series. Episode one examines the KT Boundary and what it meant in terms of mass extinction. It explores evidence and keys...

Almost 100 slides explore the history of life and how it has changed over time. Full of photos and graphics, the colorful text is highly informative. You could go through these slides, pick and choose which you might want to highlight,...

Give your earth scientists or evolutionary biologists a very brief overview of the history of planet Earth using this presentation as a support. A slide explores the big bang theory and one describes the formation of our solar system. A...

What evidence supports the big bang theory? Individuals analyze scholarly resources about the the theory and develop arguments backed by evidence. They brainstorm, share ideas, watch a video, and read articles to complete a graphic...

A brief reading introduces high schoolers to different theories on the origin of life. A research project follows in which learners gather information on each theory and then hold a discussion about which they believe to be the most...

Five pages take biologists on a generalized survey of the origin of life. Queries are made regarding theories of how life developed, ancient Earth conditions, and the ever-changing field of taxonomy. The experiments of different...

The intent of this slide show is to introduce young biologists to evolution, specifically how populations change through time. The content does not support the stated objective. What you will find in this presentation is general...
