Paul Andersen explains how enzymes are used to break down substrates. The correct shape of the active site allows a key/lock fit between the enzyme and the substrate. The enzyme catalase is used to break down hydrogen peroxide. The...

In which Hank introduces us to the world of Organic Chemistry and, more specifically, the power of hydrocarbon. He talks about the classifications of organic compounds, the structures & properties of alkanes, isomers, and naming...

Mr. Andersen explains the concept of a limiting reactant (or a limiting reagent) in a chemical reaction. He also shows you how to calculate the limiting reactant and the percent yield in a chemical reaction.

Continuing our look at Nuclear Chemistry, Hank takes this episode to talk about Fusion and Fission. What they mean, how they work, their positives, negatives, and dangers. Plus, E=mc2, Mass Defect, and Applications of Fission and...

How do we grow crops quickly enough to feed the Earth's billions? It's called the Haber process, which turns the nitrogen in the air into ammonia, easily converted in soil to the nitrate plants need to survive. Though it has increased...

NASA's Cassini spacecraft has detected a huge ocean under the surface of Saturn's moon Enceladus. But how? And what does it really mean? Hank lays out the data -- straight from space to your brain!

Chemistry raised to the power of AWESOME! That's what Hank is talking about today with Electrochemistry. Contained within, Hank discusses electrochemical reactions, half reactions, how batteries work, galvanic cells,...

In this video Paul Andersen explains how the reaction quotient is used to determine the progress of a reversible reaction. The reaction quotient (Q) is the ratio of the concentration of products to the concentration of reactants. The...

In this video Paul Andersen explains how acid-base chemistry can be understood in terms of equilibrium. Water is present in all acid-base chemistry and is amphoteric in nature. The Ka and Kb values can be used to determine the strength...

Oxidation-reduction reactions are going on around us, and inside us, all the time, and we can make redox reactions in organic chemistry easier to understand by tracking carbon-oxygen bonds. In this episode of Crash Course Organic...

The complex systems of high school dating and chemical reactions may have more in common than you think. Explore five rules for speeding up chemical reactions in the lab that might just land you a date to a dance!

Today's episode dives into the HOW of enthalpy. How we calculate it, and how we determine it experimentally...even if our determinations here at Crash Course Chemistry are somewhat shoddy.

In this episode, Hank goes over Reversible Reactions, the water dissociation constant, what pH and pOH actually mean, Acids, Bases, and Neutral Substances as well as the not-so-terrifying Logarithms, strong acids, weak acids,...

In this video Paul Andersen explains how chemical reactions progress as bonds are broken and reformed reformed. He explains the difference between changes in state and changes in molecules. He discussed collision theory and explains...

Powder vs. Soda: an important distinction!

Jessi and Squeaks discover some amazing ocean creatures, ones that glow by themselves!

We all have emotions, but what exactly are they and where do they come from?

In this video Paul Andersen explains why the slowest elementary step in a chemical reaction is the rate-limiting step. This step can be used to determine the overall rate law of the chemical reaction.

Everyone feels angry sometimes, and anger is a natural way that our bodies keep us safe from danger! Jessi and Squeaks are here to tell you all about why we feel angry, and how to control it when getting in mad isn't the right choice!

New ReviewThis engaging program explains how chemical reactions can be described and written. Special emphasis is focused on how chemical reactions involve the rearrangement of atoms, but not the overall change in mass (Law of the Conservation of...

Let's make Higgins' erupting volcano a proper science project!

This vido outlines the structure of the human nervous system and describes the purpose and role of each element.

This episode is not for the faint of heart. Coyote has claimed for years that he’s immune to poison ivy—but that’s about to be put to the ultimate test. Joined by wildlife expert, Ray Tiller (who, spoiler alert, breaks out from even a...

This video provides an introduction to Newton's three laws of motion, explaining how they help us understand the movement of objects in our everyday lives. It discusses the first law of inertia, which states that an object remains still...
