We are excited to share our newest lesson plan, “Using primary sources to understand eugenics.” Students are invited to explore the origins and execution of the American eugenics movement in the early part of the 20th century by studying this collection of original documents and images. The lesson contains background reading, slides with detailed teacher notes, a classroom activity and a student assessment. It is aligned with Common Core standards. We have found students are fascinated by this topic and are often hearing about this era for the first time when we present this at the high school level. Appropriate in the biology, history, bioethics or sociology classroom, this lesson extends many of the ideas presented in our lesson, “History, eugenics and genetics.” As always, we are keen to hear feedback about any and all of our lessons from teachers and students.
