Why does February have 28 days when all the other months get 30 or 31? The answer is part superstition, part politics, and parts astronomy. (Basically, it's the Romans' fault)

Educational video for children that talks about what landslides are. A landslide is a displacement of a large mass of earth or rocks that slides from a higher elevation to a lower one. Landslides can be caused by different factors, such as heavy rains, earthquakes, volcanoes or simply by instability in a particular area of land. As with other natural disasters, human action can intensify the severity of landslides. Deforestation is one of the triggers: when there are no roots to help keep the soil together, the soil becomes wet due to rainfall and landslides occur.

This video is a very useful and interesting resource for children. It is perfect for teaching about landslides. It is an excellent video for preschool and elementary school.

This chemistry video tutorial provides a basic introduction into the half reaction method which is useful for balancing redox reactions in basic solution and in acidic solution. This video shows all the steps needed to balance the oxidation reduction reaction. First, separate the reaction into two half reactions. Balance the number of atoms and the charge on both sides. In acidic solution, you can add H+ and H2O to balance the particles. In Basic solution, you can use OH- and H2O to do so. Add electrons to the side with the highest charge to balance the total charge on both sides of the chemical equation. Make sure the number of electrons are the same on both half reactions before adding the two to get the net reaction and that's it.

Continuing with last week's calculus introduction, Shini leads us through how integrals can help us figure out things like distance when we have several other essential bits of information. Say, for instance, you wanted to know how far your window was off the ground. You can figure that out by using integrals, a tennis ball, and a stopwatch! It's all here in this episode of Crash Course Physics!

Slave codes were a method of protecting the investment of white enslavers in the Colonies by restricting the lives of enslaved people in almost every imaginable way. The codes restricted enslaved people’s ability to move around, or engage in commerce that could make them financially independent - they restricted the opportunities that would allow them to live with even relative freedom. Today, we'll learn how Colonies put laws in place to restrict the movement and freedoms of enslaved people and free Black people.

We follow up last week's tour of the central nervous system with a look at your peripheral nervous system, its afferent and efferent divisions, how it processes information, the reflex arc, and what your brain has to say about pain.

Pssst... we made flashcards to help you review the content in this episode! Find them on the free Crash Course App!
