The History of Corn – A TED-Ed Lesson

Pictures of corn like the one in this blog post have become symbols of fall harvest and Thanksgiving. Corn and many products made with it are a staple of the diets of many of us today. How did corn become a staple of our diets? What has enabled it to become one of the most cultivated crops in the world? And what are the consequences of cultivating so much corn? Those questions and many others are addressed in a new TED-Ed lesson titled How Corn Conquered the World.

Applications for Education

This TED-Ed lesson could be the jumping-off point for more or deeper lessons about how agriculture affects many parts of our lives whether we realize it or not. For example the graphs at toward the end of the lesson illustrate how increased corn production contributed to increased meat production and both of those things create environmental impacts. The increase in cheap corn production also increases the amount of cheap junk food which in turn can lead to obesity.
