What is coral bleaching? Tackle a trendy topic with a narrated animation. Through a combination of video and illustration, the narrator introduces viewers to a coral reef, then goes inside a coral polyp to show its symbiotic relationship...

Let there be light in your classroom with a video that explains that light travels in waves, the electromagnetic spectrum contains seven colors, and the color of an object depends on which light waves it reflects and absorbs. With...

This clip picks up right where the Khan Academy's Photosynthesis video left off. Chemicals such as hydrogen and compounds such as NADPH are reviewed along with details including the stroma, thylakoid, lumen, and grana. See the parts of a...

Obtain a basic understanding of photosynthesis at a chemical level. The steps involved are introduced and simplified, but they are still challenging to understand. I suggest using this resource to supplement a lecture. An overview is...

Why are neon signs so bright and colorful? Scholars discover how artists create neon signs and find out that neon is not the only gas they use in their production. Next, they explore the history of neon signs and how their development...

How far back in time can scientists see? Currently, the earliest photo of the universe is the cosmic microwave background, but math models prove the universe existed long before that time. An installment from the SciShow Space series...

What can the electromagnetic spectrum tell us about the sun? As it turns out, quite a bit! See the sun in a whole new light with a video from NOVA's Sun Lab unit. The narrator describes the electromagnetic spectrum in terms of visible...

Welcome to Sun 101! What better way to gain an understanding of our star than to learn about its anatomy? Physical science scholars peer inside to discover the inner workings of the sun through a video and discussion questions. The...

Can photons be split? It appears that way! Observe as one photon becomes two during a video from an informative physics playlist. The resource examines the nature of photons, how the crystals can help increase or decrease the number of...

Can scientists take a picture of the universe before the planets formed? Using telescopes and new technology, scientists take more detailed photos every few years. Cosmic inflation challenges our understanding of the early universe.

Scientists know mass is energy, but what is energy? An engaging Space Time video delves into the topic as part of its The Origin of Matter and Time playlist. From quarks and gluons with no mass to the gravitational effect, the true...

Some define time by motion, but how exactly does this work? Space Time added a video as part of its The Origin of Matter and Time playlist to explore just this question. It breaks down the relationships between matter, motion, and time....

Time does not exist as a universal constant, yet it can be defined as a concrete reality. These concepts and more provide the inspiration for an episode of Space Time's larger series of the same name. It discusses causal order, the...

Are light sabers possible? Could the Death Star really vaporize a planet the size of Earth? Take a look at the science behind the fiction with a video from the American Chemical Society's Reactions series. Physicists sound off on the...

Is there really more than one black? Although your crayon box may tell you otherwise, some blacks are, well, blacker than others! Discover the cutting-edge technology at work to produce the blackest black possible with a video from the...

Visualize the vastness of an atom. The video, part of the Veritasium playlist, discusses the amount of empty space within an atom. The presentation describes the theory of quarks and how that empty space is not empty after all. Using a...

When we touch something, what actually happens? Young physicists get in depth with electrons in a video from Veritasium. The narrator first explains the intricate interactions that occur at the subatomic level before answering a variety...

Is it possible to travel faster than the speed of light? In a word, no—not so far, at least! Explore the possibilities with a video from Veritasium. The narrator responds to viewer-submitted ideas for creating devices or conditions that...

Think you know a lot about the universe? You may, or may not, be right! Aspiring astrologists examine our ever-expanding universe with a video from the Veritasium playlist. The narrator discusses the observable universe, the time it...

How does a single photon show a phase shift? Using the interference pattern created by light traveling through a double slit, the resource asks whether the interference pattern would still show if only one photon of light is sent at a...

How can light be both a particle and a wave? With characteristics of each, the idea of light can be confusing. A lesson in the Crash Course physics series introduces scholars to quantum mechanics and how scientists use it to understand...
