There's a lake so deadly that anything that goes for a swim gets pickled. Yet there's a thriving ecosystem literally living on the edge, which might give astrobiologists a hint at how life could thrive on other worlds.

In this video Paul Andersen explains how intermolecular forces differ from intramolecular forces. He then explains how differences in these forces account for different properties in solid, liquids and gases. Some of these properties...

How can bottles and balloons help explain the different laws that govern gas? See how Boyle's Law, Charles' Law, and Avogadro's Law help us understand the laws that govern gas properties.

The water in your faucet may once have been part of a cloud...or a snowflake...or even the ocean! And it’s all because of the water cycle!

Our journey through the solar system continues, as Jessi gives you a close look at comets and asteroids!

The planets in our solar system have a very specific order. But have you wondered why they have the order they do?

Did you know the moon has a tail? No one did, until 1998, and we've been trying to figure it out ever since.

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...

Looking at particle movement in states of matter.

A video entitled "Composition of the Atmosphere" which talks about what gases are found in the atmosphere, what happens in photosynthesis, and what the ozone accomplishes.

This video defines ecology and ecosystems.

What happens to your atoms when you die? About 100 billion people have died since the dawn of humanity. Since the law of conservation of matter says that matter cannot be created or destroyed, all their atoms have to be still be around....

Howcast - Learn how to make pour-over coffee from the experts at Third Rail Coffee in this Howcast video.

Discusses equilibrium in gaseous reactions and the role of partial pressures

The quantum mole software, developed at University College London, helps computer companies select cleaner gases for chip etching processes. It allows users to study the interaction between electrons and various molecules, aiding in the...

Exploring the Core: Basic Solid Properties Solids diffuse slowly compared to liquids and gases, as constituent particles are closely packed, allowing little space for movement. They have a higher density than gases and liquids. Most...

Discharge tube experiments are crucial in understanding atomic structure and the discovery of subatomic particles. These experiments involve the interaction of electricity with gases at low pressures, observing cathode rays and their...

An Introduction to Solid State A solid is a form of matter with rigidity, a definite shape, and a definite volume. It differs from gases and liquids, which have fluidity determined by the relative free motion of their molecules. Solids...

It was the scene of the most cataclysmic natural disaster in American history, a place of unimaginable devastation. Today, the crater of Mt. St. Helens Volcano is experiencing a rebirth — it’s the site of the world’s newest glacier. Not...

The discoveries James Webb has made beyond the visible light spectrum.
