He is working with a puppy named Arty for one year. His job is to socialize Arty and teach him to follow commands. At the end of the year, Brett has to bring Arty back for more training so he will be ready to work with a person who has a visual imparity. Brett knows his work is for a very good cause. When it’s time to give up the puppy, he isn’t too disappointed.
In this video from PBSLearningMedia, students learn Presidents Day is an opportunity for the country to acknowledge the leaders of its government. See how it evolved from a birthday party for George Washington to observance for all of the Presidents.
In this lesson from iCivics, students take a look at two political thinkers that spent a lot of time trying to answer the question, "Why Government?" - Thomas Hobbes and John Locke. This lesson combines our Influence Library entries on these men and adds activities that ask students to compare and contrast Hobbes and Locke and to think about how these philosophers influenced those that followed in their footsteps.
In this lesson from iCivics, students learn about the different forms of government that exist, including democracy, autocracy, oligarchy, and others. They compare and contrast these forms, and they look at real-life examples in the world today.
In this lesson from iCivics, students learn what keeps the government from having too much power. The lesson outlines five basic limits on government. Students analyze the true story of former Peruvian president Alberto Fujimori, in which many of those limits disappeared, and they evaluate fictional cases of governments with limits missing. The concepts in this lesson prepare students to understand why the U.S. Constitution is structured the way it is.
In this lesson from iCivics, Students learn about the rule of law and how it protects individual rights and freedoms. By performing short, scripted skits that illustrate what life might be like without the rule of law, students identify six factors that make up the rule of law and analyze how each factor affects daily life. Students then make connections between the rule of law and America’s founding documents and think about the relationship between the rule of law factors.
This episode of Crash Course Chemistry 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.
Life is chaos and the universe tends toward disorder. But why? If you think about it, there are only a few ways for things to be arranged in an organized manner, but there are nearly infinite other ways for those same things to be arranged. Simple rules of probability dictate that it's much more likely for stuff to be in one of the many disorganized states than in one of the few organized states. This tendency is so unavoidable that it's known as the 2nd Law of Thermodynamics. Obviously, disorder is a pretty big deal in the universe and that makes it a pretty big deal in chemistry. It's such a big deal that scientists have a special name for it: entropy. In chemistry, entropy is the measure of molecular randomness, or disorder. For the next thirteen minutes, Hank hopes you will embrace the chaos as he teaches you about entropy.
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.
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 good at fostering life on Earth.
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.
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.
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 information on things like London dispersion forces, hydrogen bonds, cohesion, adhesion, viscosity, capillary action, surface tension, and why liquids are just weird.
In this episode, Hank illustrates the ideas of solutions and discusses molarity, molality, and mass percent. He also discusses why polar solvents dissolve polar solutes, and nonpolar solvents dissolve nonpolar solutes.
In this episode of Crash Course Chemistry, Hank goes over the ideas of keeping your life balance, 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.
In this video, 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 and conditions of reactions and use RICE tables all with some very easy, not-so-scary math.

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.
In this video, Hank discusses 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.
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 where you will learn about solid networks, diamond and graphite network structures, and sheet and 3D networks. It's not making diamonds from scratch, but it's still pretty cool.
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.
