The Dust Bowl

The Dust Bowl The Dust Bowl refers to a period of severe dust storms and soil erosion in the Great Plains during the 1930s. This region included Oklahoma, Texas, Kansas, Colorado, and smaller parts of New Mexico and Nebraska Image retrieved from http://capita.wustl.edu/namaerosol/Dust%20Bowl%20map.htm

Dust Storms Image retrieved from http://en.wikipedia.org/wiki/File:Wea01422.jpg There were more than 300 dust storms, also known as “Black Blizzards,” between 1933 & 1938. These storms often featured fast moving clouds of dust several miles wide that covered farms and homes, destroyed crops, and made people sick. One of the hardest hit areas was the Oklahoma Panhandle.

Displacement and Migration Many people left the Dust Bowl region, abandoning their homes and to look for work in Western states, such as California. However, many stayed behind.

Central Historical Question What caused the Dust Bowl? Since the 1930s people have debated what caused the Dust Bowl. Historians continue to address this question: Was the Dust Bowl a natural disaster or was it caused by people’s actions? Today we are going to analyze and compare a set of primary and secondary sources to better understand what caused the Dust Bowl.

The graphic organizer will go on your LEFT SIDE. You will put your answers to the guiding questions in your RIGHT SIDE

Documents A and B You will now read and compare accounts of the Dust Bowl from 2 people who lived through it. Think about what life was like, compare the similarities and differences of the documents, and consider how the documents help answer the Central Historical Question. In pairs, read the documents, answer the guiding questions (in your RIGHT SIDE), and fill out the correct portion of the graphic organizer (in your LEFT SIDE)

Documents A and B Document A: Henderson Document B: Svobida What type of document is this? When was it written? Why was it written? According to Henderson, what are three changes that happened in Oklahoma during the 1910s and 1920s? What is her attitude about these changes? How does the author describe life in Oklahoma in 1935? What are two examples of how people experienced the Dust Bowl? How does this document help you address the question: What caused the Dust Bowl? Who wrote this document? When was it written? Why was it written? According to Svobida, how did the dust and wind affect crops? What exactly does Svobida mean by the phrase “power farming”? What would be the difference between traditional farming and “power farming”? What, according to this Svobida, were two causes of the Dust Bowl? How is Svobida’s account similar to and different from Henderson’s letter?
