Paul Andersen explains how biogeochemical cycling is used to move nutrients from the environment into living material and back again. He explains the water cycle, the carbon cycle, the nitrogen cycle and the phosphorus cycle. He also...

You might not need to throw away your broken glasses and get new ones anymore, thanks to these unique materials that can heal themselves!

Before moving on from Jupiter to Saturn, we’re going to linger for a moment on Jupiter’s moons. There are 67 known moons, and 4 huge ones that we want to explore in greater detail. Ganymede is the largest - larger, in fact, than any...

All the magic that we know is in the transfer of electrons. Reduction (gaining electrons) and oxidation (the loss of electrons) combine to form Redox chemistry, which contains the majority of chemical reactions. As electrons...

Huge container ships relying on fossil fuels transport all kinds of goods across the ocean, creating a huge climate change impact. But there's a better way to power this transport using, of all things, water.

Ever wonder what all those names on the periodic table actually mean? There's a whole lot of fascinating history on Mendeleev's table. Some carry names from antiquity, some are named for people, some are named for places, and some are...

In this video Paul Andersen explains how biogeochemical cycles move required nutrients through the abiotic and biotic spheres on our planet. Matter on the Earth is conserved so producers must receive required nutrients through the water...

SciShow Space takes you on a tour of Venus, a world with such an extreme environment that you might call it "Earth's evil twin."

Last week, Hank talked about how stuff mixes together in solutions. Today, and for the next few weeks, he will talk about the actual reactions happening in those solutions - atoms reorganizing themselves to create whole new...

Paul Andersen introduces the nucleic acids of life; RNA and DNA. He details the history of DNA from Griffith, to Avery, to Hershey and finally to Watson and Crick. He also details the difference between prokaryotic and eukaryotic...

What do macaroni salad and gasoline have in common? They are made of exactly the same stuff -- specifically, the same atoms, just rearranged. So, while we put the former in our mouths and the latter in our cars, they are really just...

In this video Paul Andersen describes the structure and explains the properties of molecular solids. High intramolecular forces hold electrons and reduce conductivity, whereas low intermolecular forces decrease the melting point. ...

What makes crystals grow into their signature shapes? Dig into the atomic patterns and unique properties of crystals. -- Many crystals have signature shapes— like the cascade of pointed quartz or a pile of galena cubes. Every...

Mr. Andersen shows you how to name covalent and ionic compounds.

Welcome back to the Fluctus Channel for a mind-blowing walk with one of Indonesia's miners of volcanic sulfur. These men risk their lives to enter a 1000-foot hole at the top of a volcanic mountain to mine sulfur for just a...

How Does our Olfactory system work? How do we Smell? It turns out that quantum mechanics plays a big role. What you may not realize is that inside your nose rests a very sensitive quantum device that uses complex...

In this video, we'll be looking at the different types of notation and how they're used to represent the atomic structure of elements. We'll be using both symbolic and isotope notation to show the different properties of the...

A covalent compound is formed when 2 nonmetals bond together. When we have a covalent compound we have to use a specific set of naming rules. The first rules is that the first element keeps its name. The second rule is that the second...
