Today, Craig is going to dive into the history of American political parties. So throughout most of United States history our political system has been dominated by a two-party system, but the policies and the groups that support these parties have changed drastically throughout history. There have been five, arguably six, party systems since the election of John Adams in 1796 (George Washington’s presidency was an unusual case, and we’ll get to that), so we’ll look at the supporters and policies of each of the parties during these eras and look at how historical contingencies cause these policy shifts. We’ll also talk a bit about the benefit of a third party, which although rarely ever wins, helps to influence political debate. (10:48)

The instructor uses a white board for demonstration and this video is suitable for high school students. Students learn to solve a system of linear equations by graphing. The first step is to graph each of the given equations, then find the point of intersection of the two lines, which is the solution to the system of equations. If the two lines are parallel, then the solution to the system is the null set. If the two given equations represent the same line, then the solution to the system is the equation of that line.

Droughts claim more victims each year than any other natural disaster. Depending on where it occurs and how long it persists, the cost of a drought can run into the billions of dollars. Droughts cause more than economic hardship, however. As this video segment adapted from NASA's Goddard Space Flight Center demonstrates, droughts have a complex web of impacts that also affect us socially and environmentally. Closed captioning included. (01:40)
