Jessi and Squeaks love to race each other! They can both run pretty fast, but there's one animal they'd never be able to beat: the cheetah! Join us to learn all about this super speedy cat!

In this video Paul Andersen explains the different forms and units for energy. A discussion of the laws of thermodynamics is also included. Sample conversion problems using dimensional analysis is also included.

Your interstellar police squad has tracked a group of criminals to a cluster of seven planets. Now you must apprehend them before their reinforcements arrive. Of course, the fugitives won't just stay put _ they'll try to dodge you by...

Obesity is an escalating global epidemic. It substantially raises the probability of diseases like diabetes, heart disease, stroke, high blood pressure, and cancer. But what is the distinction between being overweight and being obese?...

Though our Sun is something we can count on to rise and set each day, it also comes with some phenomena that can catch us by surprise: solar winds. To better predict when these winds will travel all the way to Earth, we sent the Parker...

Does your toilet water drain differently than in the other hemisphere? Is it because of the Coriolis effect? Hank has some things to clarify about these questions, and more in this edition of I Don't Think It Means What You Think It Means.

Listen, we know you've thought about it, and we're here to give you THE DEFINITIVE ANSWER to one of the greatest science questions of all time. How long would it take to get to the MOON by farting? Join Gabe on PBS Space Time as we walk...

Around the world there are more than 600 plant species that supplement a regular diet of sunlight, water and soil with insects, frogs and even rats. Flies, tadpoles and beetles fall prey to the remarkable, predatory antics of carnivorous...

If you were to orbit the Earth, you'd experience the feeling of free fall, not unlike what your stomach feels before a big dive on a roller coaster. With a little help from Sir Isaac Newton, Matt J. Carlson explains the basic forces...

In this video Paul Andersen explains for the position of an object over time can be used to calculate the velocity and acceleration of the object. If a net force acts on a object it will experience an acceleration.

Join SciShow Space as we complete our tour of the Solar System planets with the ice giants, Uranus and Neptune.

This week, science explains the chemical love-connection we share with our dogs, and how some of the most isolated populations of people in the world are different on the inside.

A shooting star crashes onto Earth and a hideous blob emerges. It creeps and leaps, it glides and slides. It's also unstoppable: no matter what you throw at it, it just re-grows and continues its rampage. The only way to save the planet...

World-class sprinters just keep getting faster, with some running over 40 kilometers per hour! That kind of makes you wonder… how much faster can humans get?

How DO you make a digital clock?

Today we’re going to talk about two types of cyclones: mid-latitude cyclones and tropical cyclones. Mid-latitude cyclones are huge weather systems that bring day-to-day weather in the mid-latitudes. They're the reason the weather is...

Mr. Andersen shows you how to use the factor label method to solve complex conversions.

Usually when it's snowing outside, it's really calm, pretty, and fun to play in! But there are certain types of big snowstorms, called blizzards, that can get really windy, wild, and even dangerous!

It's the beginning of a new semester! We have some psychological tips that can help you to take better notes.

Mr. Andersen explains the difference between potential and kinetic gravitational energy. He also uses physics to calculate the energy in various objects.

SpaceX CEO Elon Musk announced some ambitious plans at the International Aeronautical Congress. If he's right, we could have humans living on the moon and Mars within a decade, and you might never have an 18 hour flight again!

If you could pilot a spaceship into Jupiter and Saturn, would you ever hit anything solid? And what's it like in there? SciShow Space takes you on a tour of the two biggest gas giants in the solar system.

Why is it Hot Underground

There are all sorts of flying birds, but some of the world's biggest are ones that stick to the ground, like the awesome ostrich!
