They learn about home construction and construct a house puzzle. They also read a story about Peter McGuire and the origin of Labor Day, later constructing a Labor Day parade featuring events in labor history. Unit 3 focuses on sheet metal work. Students read about Billy, who lives in a very hot house until air conditioning is installed. They go on a scavenger hunt through the school in search of sheet metal work.
Students construct duct work, a down spout, and an ornamental sheet metal piece.
They also read about Mother Jones and her actions to eliminate child labor. Finally, they write letters to Mother Jones describing their school activities that build their work skills for future participation in the labor force. This curriculum delivers education in human capital development, the construction trades, and the historical efforts of organized labor to bring about safe working environments.
