Time Machine: Evolution, Geology

Engage young biologists with four laboratory activities that explore the fossil record. Learners examine fossil images, a fossil kit, the rock record, and geologic time scale. They even experiment with the oxygen production of an Elodea...

Take a ride through time as you learn about the status of the past, present, and future from a physics perspective. The video instructor explains the Big Bang Theory through the equilibrium of time. Learners connect the Second Law of...

How do scientists know the history of Earth before humans—or any mammals—existed? An epic "Eons" series video explains the larger history of geologic time. It highlights the eons, eras, periods, epochs, and ages scientists use to divide...

Are our universe's days numbered? Yes and no, depending on how you look at it. Travel as far into the future as possible in a video describing the five ages of the universe. The narrator begins the tale in current days, which are the...

Has your class ever wondered why time always progresses in a forward direction and why we cannot travel backward? Learners view this short video segment to explore the concept of entropy and its relevance to time in relation to their...

How does something remain the same in order to change? The video discusses homeostatic evolution from both the continuity and changing perspectives. An analysis of the excretory system in flatworms, earthworms, and vertebrates shows...

As the great and hilarious Tim Minchin once said, "Science is simply the word we use to describe a method of organizing our curiosity." Science is more than just a guess; it is based on questions, observations, and evidence. High...

Humans share about 50% of their genes with a banana. In the video, scholars analyze the scientific evidence for evolution. The instructor spends time discussing Darwin and biogeography, fossils, and homologous structures. Scholars then...

Vision is arguably the most important of the five senses, but exactly how did we come by this amazing ability?  Find out with this engaging video on the 500 million year evolution of the human eye.

Scientists noticed animals with backbones share similar bone structure despite having different forms, such as fins, arms, and wings. Young scientists gain an appreciation for evolution by understanding the history of the theory. They...
