Elements vs Alloys
We compare melting points of lead and tin to the melting point of their alloy, solder. By timing how long it takes samples of each to melt, we discover that the melting point of solder is actually lower than those of both lead and tin....

Liquid Nitrogen Demos
We look at how different materials change when they are exposed to liquid nitrogen. Flowers become frozen and stiff and the petals snap. A banana hardens and is strong enough to be used as a hammer and a squash ball becomes very brittle...

Reactivity Series: Comparing the Reactivity of Group 1 and Group 2 Metals
We compare the reactivity of Group 1 and Group 2 metals. We add sodium and then potassium to water. We observe the reactions. Next we add magnesium and then calcium to hydrochloric acid and observe the reactions. The results let us put...

Hydrolysis of carbohydrates
Hydrolysis is a water-based chemical reaction, where water is used to break down a specific substance or molecule. In this video, we will look at a specific type of hydrolysis - hydrolysis of carbohydrates. We will learn how water is...

Instant Crystals
We use a supersaturated solution of sodium ethanoate to demonstrate instant crystallisation. Sodium ethanoate is added to water and is then heated to allow all of the crystals to dissolve. When it is cooled it forms a supersaturated...

Chemistry 502: The World of Atoms is Not Enough – Bonding Part II
"The name is Bond. James Bond." Or is that "Chemical Bond?" Assign the viewing of the video as homework, and then have your chemists come to class to practice drawing electron dot diagrams and Lewis structures with the several bonus...
Crash Course
Water - Liquid Awesome
If H2O is water and H2O2 is hydrogen peroxide, what is H2O4? Drinking, bathing, and cooking among others. Viewers of a short video explore water through its molecular structure, its ability to stick to itself through adhesion (cohesion...
