Your cell phone is mainly made of plastics and metals. It's easy to appreciate the process by which those elements add up to something so useful. But there's another story we don't hear about -- how did we get our raw ingredients in the...

In this video Paul Andersen describes the history of calorimetry and explains how it can be used to measure energy changes in a system. The specific heat of water is well established and so as a system releases or absorbs energy from a...

Mercury thermometers are handy and useful, but they could be extremely dangerous to bring on planes.

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...

When you think of surfactants, you might think of soaps, detergents and other man-made chemicals. But it turns out that some other animals utilize their own versions of these sudsy molecules.

Ever notice how cereal clumps up in your bowl, or how cereal sticks to the edges of the bowl? Bubbles in beverages do the same thing.You've probably seen this surface tension and buoyancy at work, but did you know there's some...

Despite water covering 71% of the planet’s surface, more than half the world’s population endures extreme water scarcity for at least one month a year. Current estimates predict that by 2040, up to 20 more countries could be...

Big, fiery rocket launches are just too powerful for something like a toaster-sized CubeSat once it’s in space. Electrospray propulsion is a promising new way to move these little satellites.

In this video Paul Andersen explains the important properties of solutions. A solution can be either a solid, liquid or gas but it must be homogeneous in nature. The solutes can not be separated with a filter and so either...

Water can dissolve more substances than anything else on earth...so why doesn't it dissolve everything away?

Have you ever heard the phrase, 'You look like a Million Bucks?' Well, you do... but you also look like a million particles. In this episode, Sabrina talks to us about matter and particles and that all matter is made up of particles....

How do plants keep their roots cozy? #shorts #science #SciShow

In this video Paul Andersen explains how gases differ from the other phases of matter. An ideal gas is a model that allows scientists to predict the movement of gas under varying pressure, temperature and volume. A description of both...

Magnets are amazingly strong... but there's a very easy way to destroy them. All you need to know is a little bit about ferromagnetism, paramagnetism, and temperature!

Glacier ice is weird. It's solid. Solid things aren't supposed to flow. But glacier ice flows like a liquid, and it does that without melting! How is this possible? I traveled to Mendenhall Glacier in Juneau, Alaska to find out.

Mr. Andersen gives a brief description of matter. The five states of matter are also discussed.

Alcohol has been an important part of human culture for a very long time, and from the basic process, we've figured out how to create a wide variety of alcohol beverages!

In this video Paul Andersen compares and contrasts the properties of solids and liquids. Solids have a more organized structure which can either be amorphous or crystalline. In liquids the intermolecular forces are lower and so the...

In this video Paul Andersen explains how the chloroplast in plants harnesses power from the Sun to form high energy molecules like glucose. The structure of a chloroplast as well as a brief discussion of the light reaction and Calvin...

For life to evolve on Earth, a bunch of complex organic molecules had to evolve a way to assemble into cells. So how did those proto-cells get cell membranes? Some researchers have a new hunch. Also, scientists are borrowing a trick from...

You might not believe it, but the same chemistry that brought us bulletproof vests and modern sailing sails also gave us the technology to build your smart phone. But that doesn’t mean these chemists were thinking about these...

Hank teaches us why water is one of the most fascinating and important substances in the universe.

Water travels... a lot. In fact, the water cycle is amazing and takes water all over the planet by using evaporation, condensation, and precipitation. In this episode of Crash Course Kids, Sabrina shows us how the water cycle works and...
