As the rates of skin cancer rise to become the most common type of cancer in the United States, scientists directly relate sunscreen usage to skin cancer prevention. Doctors research exactly how ultraviolet light changes cells. Viewers...

The sky appears blue, but why? Humans see the world through the visible light spectrum, but the light spectrum is much larger than what the eye sees. Camera lenses allow people to view the world in ultraviolet, and the changes might...

Earth's magnetic field protects people from solar wind, radiation, and many other potentially catastrophic events. For reasons not yet understood, the magnetic field appears measurably weaker over the course of less than 200 years, a...

Neutrons have approximately the same mass as a proton, but contain no charge. Something so seemingly insignificant changed the world thanks to nuclear weapons, nuclear energy, and nuclear radiation. Viewers learn more about the invention...

CPT theory is the basis for much of physics, but what happens when researchers disprove the theory piece by piece? Explore the idea with a video about the Nobel Prize-winning breakthroughs that shifted the entire way scientists...

Scientists have been studying the surface of Mars for many years ... it's time to know a little something about its interior, too. The Mars Insight launched in November 2018 on a mission to study the happenings inside the most studied...

Precision is imperative in science! Learn how science defines units of measure and how that changed for several units in 2018. A video lesson describes the history behind the definition of the kilogram, and the narrator then explains why...

An analysis of launched objects helps scholars understand general relativity in greater detail. These aren't just any launched objects, though! A video presentation describes the gravitation potential energy of satellites in orbit and...

Have scholars ever wondered what a black hole looks like? See the first image of a massive black hole and learn about what a black hole is, how it forms, and how telescopes took images from around the world. The video then relates the...

Why is the spin of a black hole important? Scholars explore spinning black holes and how they relate to momentum, matter, and mass. They investigate the different parameters that are used to measure black holes by understanding how they...

Magnetic micro-robots aren't just really cool, they have some potential practical purposes. An episode from the Veritasium introduces learners to the micro-robots and their possible future roles in biomedicine. Actual footage of the...

A Los Angeles reservoir is the largest ball pit on Earth. Learn the problem and solution of the water treatment plant in LA in a Veritasium video lesson. An unexpected chemical reaction created an issue in the treatment of water, and the...

The world's lightest solid is over 99 percent air. An episode of the Veritasium series examines the structure of the aerogels and their physical and chemical properties. The video shows several demonstrations that show these properties...

This is a solid introduction to the European Union and the debt crisis of the late 2000s through 2012. Class members watch a PowerPoint, take notes, read passages, answer questions, and work in groups to write a fable that illustrates a...

Put a pair of grapes in a microwave, sit back, and watch the show! A video lesson shows how microwaves make plasma from the components of the grapes. The narrator interviews experts in the field to explain how the frequency and...

It is true that Earth has a magnetic field, but do human bodies detect it? Part of a larger series, an interesting video lesson describes an experiment that attempts to answer the question. Using brain scans while exposed to a simulation...

The world of compliant mechanisms is only limited by the imagination! The video lesson begins with a comparison between traditional machines and compliant mechanisms. The scientists then explain the advantage of having flexible, bendable...
