Crash Course is a small YouTube channel featuring a couple of short, fast-paced video lessons about World History. The two history videos on the channel right now are Indus Valley Civilization and The Agricultural Revolution. Both videos move very quickly, almost frantically at times, making them more like entertaining overviews of these topics than serious lessons. There are a couple of innuendos thrown into both videos, so watch them and use your discretion before showing them in your classroom.
