Liquid nitrogen makes microscopic ice crystals, which make for a creamier food product than normal freezing. A gastronomical video explores nine different cooking techniques that are scientifically based. From food pairing to using...

Foods are fried in oils, which are basically a fat that is a liquid at room temperature. Another great video about the chemical reactions in cooking, this one explores frying food. The narrator explains that from the appearance of...

How do you measure when a gas is lost? The 20th installment in a 29-part series explains how to determine if a gas has been lost in a chemical reaction. It continues by describing how to solve for the lost mass. Finally, it offers a...

Viewers watch while the narrator explains limiting reactions through the familiar example of a recipe. He then describes why it is necessary to use moles to solve these problems rather than just relying on diagrams. The video ends...

How does a nuclear reaction create such a large amount of energy? The idea of a nuclear reaction develops from a comparison with chemical reactions. The video instructor then explains the process of both nuclear fission and fusion. This...

What is more important, style or substance? This video explains the difference between physical (style) changes and chemical (substance) changes. It uses many examples and various ways of determining which type of change has occurred. 

The title says it all for a video that explains chemical communication between animals with the popular question: why do dogs smell each other's butts?

Explain the purpose and structure of carbohydrates with a scientific video that goes in depth about monosaccharides, disaccharides, oligosaccharides, and polysaccharides. It offers an explanation of how they grow and shrink through...

High school chemists concentrate on the formation of polymers through condensation reactions. A video also explains the process of breaking them down through hydrolysis.

Energy from the sun travels millions of miles, and actually helps you move your thumb. Observe how reactions work together to release and consume energy, such as the power of a river grinding grains, which allows processes to occur....

Two plus two is four, but how can two liquids come together and form one solid? Learn how ions can mix in solutions and fall out to form a solid in precipitation reactions through discussion and analysis of cations, anions, and...

What did one titration say to the other titration? Let's meet at the end point. The first video explains titration, while the second installment contains a one-question quiz and a demonstration of titration.

What do you create with the electrolysis of water — and why? Answer this question and others with the in-depth video perfect for learners new to the concept. The instructor explains the significance of the positive and negative electrode...

A set of three videos starts with the instructor explaining acid and base conjugate pairs. Then, two one-question quizzes reinforce knowledge. 

Focus on the basics of solubility in chemistry with an explanatory video, which focuses on how to solve solubility problems and common ion effect calculations. 

Ever wonder why old headstones in cemeteries are difficult to read? Learn about acid-base reactions and how these contribute to the defacing of statues and headstones and how improving the way we burn coal has decreased these effects.

What occurs once a substrate binds to a protein? High schoolers view a short animation to witness the action of substrate binding and the resulting changes that occur in the protein. They conclude the video with a short discussion...

Jump-start your understanding of catalysis in chemical reactions. An educational video explains the basic concept of catalysis and its relation to energy. It also introduces platinum plates as a catalyst for the reaction between...

Ever wonder how salt forms? Watch as a video instructor adds a solid sample of sodium to chlorine gas to form salt. The video then explains chemistry concepts associated with the reaction.

Learn about how chemical reactions require energy to activate and how to draw energy diagrams for chemical reactions. After watching the video, learners discuss why mixing hydrogen and oxygen gas in a balloon won't result in water.

Has your class ever wondered exactly what jump starts chemical reactions within the body? Pupils view a short video segment that animates a chemical reaction, complete with enzymes and substrates, so they may further understand this...

Who was Sir Newton and why are his laws so important today? Young scientists find the answer to this question as they explore Newton's Laws through the dynamic video segment. Pupils take part in a discussion and piece together the...

Ah, chemical reactions and gases ... there always seems to be more to learn. This short and detailed video segment describes double displacement reactions (gas evolution reactions) to create a gaseous byproduct. Four gases discussed in...

Provide your emerging chemists with the most descriptive way to perform specialized double displacement reactions possible! This video details acid-base neutralization, where acids and bases are combined to result in salt and water...
