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...

Humans have only inhabited the earth for a fraction of the time that life has existed. Young scientists explore the facts about the emergence of life on Earth with an interactive resource. While highlighting different types of life, the...

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:...

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...

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...

How did life on earth begin? Is there a scientific explanation that could show how life arose from chemical reactions? Discover the answers to these questions and more as you watch a basic explanation of the hypotheses currently being...

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...

Young scholars create and observe coacervates. In this origin of life lesson, students create coacervates by mixing carbohydrate and protein solutions. They observe the life-like qualities of the structures and discuss the origin of life.

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...
