The Sumoi NPP satellite collects light from Earth's surface during nighttime hours. From the images produced, scientists can study populations, pollution, sea ice, moon phases, and more! This brief video clip would be a high-quality...

Turtles are more than just cute, docile sea creatures; many of them are endangered, some critically. The leading threat to Pacific leatherback turtles is human activity. From commercial fishing and boating in the leatherbacks' migratory...

According to Einstein's theory of special relativity, nothing can go faster than the speed of light, but Einstein didn't know about neutrinos. In fact, physicists are just beginning to be able to study these tiny particles that zip...

Is that warm, fuzzy family feeling a product of evolution? Explore altruism through a video from an engaging science series. The narrator discusses parental instincts, evolutionary fitness, and an organism's drive to ensure it passes its...

Change is good ... unless you're a tuatara! Meet Earth's oldest surviving reptile species in a fun video from an extensive science playlist. Content includes why the tuatara did not evolve and its unique anatomy.

How did scientists unravel the mystery of an ancient beaver species? An engaging video from a well-written biology playlist discusses the discovery of strange spiral fossils found in Nebraska farm country. Junior paleontologists examine...

Could a virus be the key to reversing color blindness in humans? Some researchers believe so, and have even tested it out on monkeys. Learn more about the experiment and its effects in a short video that could accompany a lesson on gene...

Island chains are some of the best environments to study evolution and the small adaptations that occur in an isolated ecosystem. Papua New Guinea is an excellent example of these evolutionary gems, with a diverse bird population on its...

There is a wealth of evidence to suggest that octopi are the smartest of all invertebrates; observe why as you see an octopus walk across the ocean floor carrying a coconut shell to use as shelter. The video alone is short and does not...

The award for the most effective adaptation goes to the mimic octopus, a newly described species. The octopus can change its color, shape, and behavior to mimic flounder, lion fish, sea snakes, and more. 

Can an organism with no eyes still see? As it turns out for the purple sea urchin, the answer is yes. In a short video, scientists explain why they believe that some sea urchins can use their spikes to visually sense the environment. 

You may not realize it, but you get pushed around every day. What forces are acting upon you? Young physicists explore gravitational force and normal force in a video that demonstrates both forces and their directions as they move...

Protecting buildings, bridges, and roadways from damage during an earthquake is an important task for engineers. Discover how one lab goes about testing the safety of existing and yet-to-be-built structures with a short video. See some...

Evolution occurs on large and small scales, in both living organisms and viruses. By learning the pathway taken by pathogens such as the virus that causes dengue fever, scientists can get one step closer to understanding how to stop...

Young geographers discover not only how to read and recognize coordinates on a map, but also gain a deeper understanding of latitude and longitude and how climate changes can vary significantly across latitudes.
