The Moon is typically 380,000-ish kilometers from the Earth, so it doesn't seem like they have that much of a direct influence on one another. However, the presence of hematite on the lunar surface suggests our planet is causing the Moon...

Squeaks has been learning about the platypus and now he wants to learn more about where they come from. Join us as Jessi and Squeaks explore the world down under, Australia!

While they are incredible engineering marvels, we don't think about bridges all that much. But there's a good reason we should all be thinking about our bridges, since there's a weird reason that more of them might be at risk of failure...

You look really pretty, but what are you actually putting all over your face?

Scientists are learning new things by looking at the remains of exoplanets, NASA has unveiled a new spacesuit design, and engineers fixed a problem from one hundred million kilometers away.

For astronauts, dust is no joke. On the moon and Mars, dust isn't at all like the stuff under your bed. It can be poisonous, corrosive, even made of razor-sharp glass. So future astronauts are going to need more than a dust buster to get...

Iron is crucial in many areas of life: it is found in our blood, as well as being used to build bridges. Chemistry - Periodic Table - Learning Points. Iron is one of the most common element on Earth. Iron is found in living organisms....

Combustion reactions are vital: from keeping us warm and cooking our food, to providing electricity and propelling rockets into outer space. What do we know about these chemical reactions? Chemistry - Reactions - Learning Points....

We investigate the conditions needed for rust to form. Four iron nails are placed under different conditions. One is half submerged in water. Another is completely submerged in boiled water. One is half submerged in salt water. The final...

For centuries, humans have been extracting metals from molten ores. Today, the basic technique remains the same, but how does extraction work? Chemistry - Reactions - Learning Points. Metals can be extracted from rocks if they are heated...

Upon viewing the Investigating Chemical Reactions video series, students will be able to do the following: Define a chemical reaction as a process in which substances undergo changes to produce new materials with different properties....

The video is a tutorial on how to calculate theoretical yields in chemistry. The host explains the concept of theoretical yield as the maximum mass of product that can be formed during a reaction when assuming the reaction has gone to...

The video is a tutorial on how to balance chemical equations. The instructor goes through three different equations, counting the number of elements present on each side and then adjusting the coefficients to balance the equation. The...

A new international study has measured the densities of the seven Earth-size planets around TRAPPIST-1 with extreme precision

The video is a lecture presentation on the extraction of metals. The presenter begins by discussing how the method used to extract a metal from its ore depends on the metal's reactivity. The lecture then covers the extraction of iron...

This video explains different chemical reactions used for extracting metals from their oxides. The video starts with the simple method of reduction with carbon for metals such as iron, where the metal oxide is reduced, and carbon is...

In this video, we will look at the chemistry behind the production of iron from iron ore. In early Earth history, iron, like all other metals, would have been found as an element in the crust of the planet. Later when plants evolved that...

This program provides an introduction to chemistry. We begin by discussing how chemistry touches every part of everyday life and give several examples of basic chemical reactions that students come into contact with regularly. The entire...

The video discusses displacement reactions and their relation to the reactivity series. The presenter gives examples of experiments involving metals and non-metals and explains how the more reactive metal will displace the less reactive...

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...
