Students view an image of an early cotton gin and brainstorm what might be its purpose. Then they learn about the rise of cotton plantations in the southern colonies and how they contributed to the spread of slavery. Next they examine the Lowell Mills and the cause-and effect relationship between the cotton gin and slavery. Finally, they learn about the lives of the slaves on the plantations and react to an actual ad from 1800 offering a reward for the return of a runaway slave.
Students read background information about Jamestown, early tobacco plantations, and the development of slavery in the southern colonies, along with the lesson objectives. They examine a photograph of an early cotton gin, then respond to a word cloud prompt about what the invention might be and a collaborative wall prompt about what it might have been used for.
Teacher MovesIntroduce the experience, review the objectives, and connect the topic to students’ prior knowledge about colonization and slavery. Facilitate discussion of student responses about the image, then explain that the invention is the cotton gin, describe how it worked and how much faster it cleaned cotton than manual labor, and preview that students will learn how this invention transformed the southern economy.
Students view an image of African Americans working in a cotton field and read explanatory text about the southern economy, including the shift from tobacco to cotton, the impact of fertile soil and climate, and the rise of large plantations dependent on slave labor. They read additional information about plantation owners, plantation villages, and small family farms that sometimes used a few enslaved workers. Students then answer multiple-choice questions about why farmers switched to cotton and why large plantations depended on slave labor.
Teacher MovesReview the concepts of supply and demand in the context of the shift from tobacco to cotton and how the cotton gin increased demand for cotton. Clarify that cotton became the main crop in the southern colonies and that cotton plantations relied on African slave labor. Check for understanding using the questions and address any misconceptions about crops, profitability, and labor needs.
Students examine an illustration of enslaved African Americans using an early cotton gin and read about the development of the Lowell Mills and how northern textile factories increased demand for southern cotton. They read about the Lowell Girls, their working conditions, and how mill work created limited opportunities for education and later careers. Students then read about how the cotton gin and northern demand for cotton reshaped the southern economy and led to a rapid increase in the enslaved population. They respond on a class wall explaining the cause-and-effect relationship between the cotton gin and the growth of slavery.
Teacher MovesHighlight key points about industrialization in the North, the success of the Lowell Mills, and how factory demand for raw cotton intensified southern cotton production and reliance on slavery. Share and discuss strong student explanations from the wall, guiding students to articulate the cause-and-effect chain from invention to economic change to increased enslavement. Optionally, show the video How inventions change history (for better and for worse) to deepen understanding of the unintended consequences of the cotton gin and introduce the idea of sectionalism between an industrializing, increasingly anti-slavery North and an agricultural, slave-based South.
Students view an image of an enslaved family and read about the broader history of slavery in the colonies and United States, including the shift of slavery to the South, restrictions on education and movement, harsh punishments, family separation, and the development of enslaved communities and religious culture. They learn about forms of resistance, including sabotage, self-injury to avoid work, and escape attempts. Students then examine a historical runaway slave advertisement from the Wilmington Gazette (1800), reading the text of the ad. They write a letter from the perspective of Will, the enslaved man described in the ad, explaining to his wife why he has decided to run away, and then review and respond to classmates’ letters with questions or positive comments.
Teacher MovesRead the runaway ad aloud with students, clarifying unfamiliar vocabulary and ensuring comprehension of its meaning and implications. Lead a discussion using questions about why Will might have run away, the risks he faced, why the owner offered a reward, and why enslaved people were denied education and rights. Support students as they write from Will’s perspective, encouraging empathy, historical accuracy, and thoughtful reflection, and guide respectful peer feedback on classmates’ letters.
Students complete the exit quiz by answering all the questions.
Teacher MovesFacilitate the assessment and use student data to evaluate understanding, address misconceptions, and identify areas for growth.
