Icy roads are a huge hazard, and typical methods of de-icing them can be pretty toxic to wildlife. Which is why researchers have been so fixated on finding better alternatives, from brine to pig pee.

The Moon is pretty prime real estate once you get past the lack of oxygen, resources, and general mobility, but if quality of life isn't what you're after, here's how we might make it all work.

Today, NASA announced that there is...occasionally...flowing, liquid water on the surface of Mars. What?!

In this video Paul Andersen explains how atoms are conserved in a chemical reaction. This can be seen in a chemical equation where the subscripts represent the atoms in the molecule and the coefficients represent the molecules. The...

As we look towards longer missions to the Moon, the shear amount of resources needed to survive becomes a much bigger question. Without space semi-trucks to haul life-giving resources to astronauts, can we utilize the Moon’s barren...

Spangler has the cure!

Icy steps and walkways. Everybody dreads them, but you no longer need to. Gone are the days of twisted ankles and wet behinds with this simple method of prevention.

Cations, formed by electron loss, influence ionic bond strength. Smaller cations with higher charges create stronger ionic interactions

The video talks about corrosion and its prevention methods. The video explains that water and oxygen are needed for rusting and demonstrates an experiment to investigate rusting. The video also discusses various methods of preventing...

This program covers the very important topic of ionic compounds. We discuss how ionic compounds form and how to predict ahead of time what the chemical formula will be when given the atoms that form the ionic compound. We spend a great...

This program covers the very important topic of hydrate compounds. We begin by discussing what a hydrate compound is and why they exist in nature. We discuss how to name hydrate compounds using numerous examples. The entire lesson is...

This video provides an explanation on how to balance chemical equations using examples of simple word equations. It explains the importance of multipliers and subscripts in chemical equations and demonstrates how to use them to balance...

We know that concentration is typically expressed with molarity, which is moles per liter. But how do we know how many moles of solute are present in solution when an ionic solid dissolves in water? It's not so simple because these will...

Learn the basics about Halogens and their compounds, about how we use them and much more.

Learn the basics about Rust, it's prevention and treatment. What causes rust? Why do only metals rust? How do you prevent rust? Find out more in this video!

In this video we give a detailed breakdown of Limestone and what the different uses of Limestone are.
