Crash Course Chemistry


  • Lab Techniques & Safety | Crash Course Chemistry

    Hank takes a break from the desk to bring you to the lab in order to demonstrate some important points about the practical side of chemistry - experimentation in the laboratory. You'll learn what to wear in the lab, how to dispose of chemicals safely, how to avoid the most common accidents, how to pour solutions properly, what the HazMat diamond means, what an MSDS is, and how to use a fume hood. And as a reward for sticking with him through this maybe less-than-thrilling lecture, you'll see Hank subject himself to an exciting piece of safety apparatus.

  • Types of Chemical Bonds | Crash Course Chemistry

    Atoms are a lot like us - we call their relationships "bonds," and there are many different types. In this video, you will learn that chemical bonds form in order to minimize the energy difference between two atoms or ions; that those chemical bonds may be covalent if atoms share electrons, and that covalent bonds can share those electrons evenly or unevenly; that bonds can also be ionic if the electrons are transferred instead of shared: and how to calculate the energy transferred in an ionic bond using Coulomb's Law.

  • Polar & Non-Polar Molecules | Crash Course Chemistry

    In this video, you'll learn that molecules need to have both charge asymmetry and geometric asymmetry to be polar, and that charge asymmetry is caused by a difference in electronegativities. You'll also learn how to notate a dipole moment (or charge separation) of a molecule, the physical mechanism behind like dissolves like, and why water is so dang good at fostering life on Earth.

  • Bonding Models and Lewis Structures | Crash Course Chemistry

    In this episode of Crash Course Chemistry, Hank discusses why we need models in the world and how we can learn from them... even when they're almost completely wrong. Plus, learn the glory of the Lewis Dot Structure!

    Grades: 9-13+
  • Orbitals | Crash Course Chemistry

    In this episode of Crash Course Chemistry, Hank discusses what Molecules actually look like and why, some quantum-mechanical three dimensional wave functions are explored, he touches on hybridization, and delves into sigma and pi bonds.

    Grades: 9-13+
  • Liquids | Crash Course Chemistry

    Liquids are everywhere, but at the same time, they possess some incredibly unique qualities when compared to the rest of the matter in the universe. In this episode of Crash Course Chemistry, Hank gives you the low down on things like London Dispersion Forces, Hydrogen Bonds, Cohesion, Adhesion, Viscosity, Capillary Action, Surface Tension, and why liquids are just... weird!

    Grades: 9-13+
  • Solutions | Crash Course Chemistry

    In this episode, Hank illustrates the ideas of solutions and discusses molarity, molality, and mass percent. Also, why polar solvents dissolve polar solutes, and nonpolar solvents dissolve nonpolar solutes.

    Grades: 9-13+
  • Equilibrium | Crash Course Chemistry

    In this episode of Crash Course Chemistry, Hank goes over the ideas of keeping your life balance... well, your chemical life. Equilibrium is all about balance and today Hank discusses Chemical Equilibrium, Concentration, Temperature, and Pressure. Also, he'll chat about Le Chatalier's Principle and Fritz Haber.

    Grades: 9-12
  • Equilibrium Equations | Crash Course Chemistry

    In which Hank shows you that, while it may seem like the Universe is messing with us, equilibrium isn't a cosmic trick. Here, he shows you how to calculate equilibrium constant & conditions of reactions and use RICE tables all with some very easy, not-so-scary math.

    Grades: 9-13+
  • pH and pOH | Crash Course Chemistry

    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, and how to calculate pH and pOH. Oh, and litmus paper!

    Grades: 9-13+
  • Buffers, the Acid Rain Slayer | Crash Course Chemistry

    In this episode, Hank talks about how nutty our world is via Buffers! He defines buffers and their compositions, talks about carbonate buffering systems in nature, acid rain, pH of buffers, and titration. Plus, a really cool experiment using indicators to showcase just how awesome buffers are.

    Grades: 9-13+
  • Kinetics: Chemistry's Demolition Derby | Crash Course Chemistry

    In this episode, Hank talks about collisions between molecules and atoms, activation energy, writing rate laws, equilibrium expressions, reactions mechanics, and rate-determining steps. Have you ever been to a Demolition Derby? Then you have an idea of how molecular collisions happen.

    Grades: 9-13+
  • Doing Solids | Crash Course Chemistry

    In which Hank blows our minds with the different kinds of Solids out there and talks about why they're all different and have different properties. Today, you'll learn about amorphous and crystalline solids, types of crystalline solids, types of crystalline atomic solids, properties of each type of solid, and that the properties depend on the bond types.

    Grades: 9-13+
  • Network Solids and Carbon | Crash Course Chemistry

    In this episode, Hank talks about Network solids and Carbon and how you can actually create a Diamond from plain old Carbon... well, YOU probably can't unless you own a bunch of elephants. It's a long story. BUT, within you will learn about Solid Networks, Diamond and Graphite Network Structures, as well as Sheet and 3D Networks. It's not making diamonds from scratch, but it's still pretty cool!

    Grades: 9-13+
  • Silicon: The Internet's Favorite Element | Crash Course Chemistry

    In this episode, we talk about Silicon Valley's namesake and how network solids are at the heart of it all. Hank also discusses Solid-State Semiconductors, N-Type and P-Type Semiconductors, Diodes, Transistors, Computer Chips, and Binary Code. All from the same thing that makes up sand!

    Grades: 9-13+
  • Electrochemistry | Crash Course Chemistry

    Contained within, Hank discusses electrochemical reactions. The episode looks at half reactions, how batteries work, galvanic cells, voltage, standard reduction potential, cell potential, electrolysis, and electro plating and the things that go into making it possible for you to watch this episode of Crash Course Chemistry!

    Grades: 9-13+
  • The History of Atomic Chemistry | Crash Course Chemistry

    Hank takes us on a tour of the earliest pioneers in the field of atomic theory. From Leucippus to Heisenberg to you - yes, YOU - the story of Atomic Chemistry is all wibbly-wobbly... and amazing.

    Grades: 9-12
  • Nuclear Chemistry | Crash Course Chemistry
