Footage of a male teacher engaging his students with humor and questions of geography. 

He is using an overhead projector to show his students a map of the United States. He poses the question to his students: How does one get by ship from New York to San Francisco?

A black female student says that a ship may get from NY to SF by travelling around South America.

The teacher shows a joke on the overhead projector, making a double entendre with the word “stroke.” He then asks the class where canals could be built to potentially shorten a ship’s travel route from NY to SF. One student points out four possible areas in Central America where canals could be built.
