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.

Get to know plasma, the most common, but probably least understood, phase of matter in the universe!

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

If you’re trying to figure out where to plan on sheltering during the zombie apocalypse, it’s essential to know whether zombies sink or float!

We've talked about mixtures and solutions, solutes and solvents, but what about things that can't be undone? What about Chemical Changes? Would it surprise you to know that baking a cake is a Chemical Change? Or striking a match? In this...

Some people say that buying an electric car is a great way to fight climate change - but if they use electricity that is made by burning fossil fuels, are they really more environmentally friendly than gas powered cars?

How does heat affect airplanes? Turns out heat, speed and density connect to create dangerous situations.

In today's Crash Course Astronomy, Phil takes a look at the explosive history of our cosmic backyard. We explore how we went from a giant ball of gas to the system of planets and other celestial objects we have today.

In this video Paul Andersen explains how fossil fuels are formed when organic material is heating and squeezed in an anaerobic environment. Formation, extraction, advantages, and disadvantages are discussed for coal, petroleum and...

The second part of our two part tale of the puzzle that is Earth. In this episode, Sabrina talks about the Hydrosphere and the Atmosphere and what is contained in each one. Let's dive in!!! This first series is based on 5th grade...

Today on Crash Course Astronomy, Phil explains comets. Comets are chunks of ice and rock that orbit the Sun. When they get near the Sun the ice turns into gas, forming the long tail, and also releases dust that forms a different tail....

Looking at particle movement in states of matter.

What is Chemistry? What are the states of Matter?? Find out in this video!
