The Columbian Exchange
Driving Question: What were the causes of the Columbian Exchange, and what impacts did it have on the Eastern and Western Hemispheres?
There were complex networks of exchange long before Columbus reached the so-called New World. These networks were, of course, not old to the millions of Indigenous Americans who lived there. But the new connections between Afro-Eurasia and the Americas created a truly global network that would forever alter the world’s people, plants, and animals.
Learning Objectives
- Explain the causes of the Columbian Exchange and its effects on the Eastern and Western Hemispheres.
- Use the historical reasoning process of sourcing to evaluate the Spanish conquest of the Aztec Empire from two different perspectives.
- Assess the environmental and cultural effects of the Columbian Exchange on Afro-Eurasia and the Americas.
Vocab Terms:
- cash crop
- demographic
- enslave
- epidemic
- indigenous
- plantation system
- staple crop
This opener requires some classroom prep, but it’s worth it! Be sure to download and print the Narratives in the activity ahead of time. You’ll also need a large ball of yarn and large sheets of paper to indicate continents and countries/regions. To see how other teachers set up their rooms, and for a handy slide deck to accompany this activity, check out this Community Forum post.
The world changed radically after 1450—but how? And why?
The arrival of Columbus in the New World changed everything, from the way people ate to the diseases they carried.

While you read
Look for answers to these questions:
- What were Indigenous communities in the Americas like before the Columbian Exchange?
- Why were Indigenous Americans so vulnerable to diseases?
- How did epidemic diseases affect the environment and the economy?
- What animals were domesticated by humans in the Americas, before and after the Columbian Exchange?
After you read
Respond to the following questions:
- To what extent does this article explain the causes of the Columbian Exchange and its effects on the Eastern and Western Hemispheres?
- The author of this article argues that the “Columbian Exchange completely changed the face of the world.” Based on the evidence in this article, do you agree with this assessment? Why or why not?
This activity is particularly important. It helps set a serious tone, framing the lesson as an entry into the human experience of enslavement while also preparing students to read survivor testimony with care and seriousness.
The horror people endured in the transatlantic slave trade is beyond imagining. Reading the words written by those who survived can help you begin to understand.
Did you know: In eighteenth-century Britain, pineapples were huge status symbols. They couldn’t be grown locally and were incredibly expensive. If someone wanted to show off but couldn’t afford to eat a pineapple, they could rent one for the evening to display on their dining table. Just don’t eat it!
Humans have always moved plants and animals around with us. But after 1500, a biological exchange between the Old World and the New changed populations, trade networks, cultures, and environments around the globe forever.

While you read
Look for answers to these questions:
- What’s the difference between a staple crop and a cash crop? What different economic effects did they have?
- How did European plantation owners maximize their profits?
- In what ways did European colonists impact exchange networks and the global production and distribution of goods?
- How did European use of crops and animals affect the environment in the Americas?
- What effect did the introduction of the potato have on European populations? How did this change over time?
After you read
Respond to the following questions:
- What evidence does this article provide to explain the causes of the Columbian Exchange and its effects on the Eastern and Western Hemispheres?
- In the article, the author cites Crosby’s argument that the most important change brought about by the European conquests was not political but biological. With the information you currently have, do you find the author’s argument convincing? Why or why not?
This topic’s content—and instruction on it—is particularly heavy. Students might need support understanding disease, forced migration, racial categorization, and plantation labor as part of one larger system. If you need additional help, check out the OER Project guide about teaching sensitive topics.
Parts of the world benefitted by increased global networks. But the Atlantic slaving system as well as the sharp decline in indigenous populations in certain regions were among the devastating effects of this period.

While you read
Look for answers to these questions:
- Why is it difficult for historians to determine the scale of the Great Dying?
- What groups of people migrated to the Americas involuntarily?
- What do the categories “mestizo” and “mulatto” mean? Who came up with these categories?
- How did the population of sub-Saharan Africa change as a result of the Columbian Exchange?
- What was the plantation complex? Whom did it benefit?
After you read
Respond to the following question:
- The author claims that “demographic changes in both the Americas and Africa were mostly disastrous for indigenous peoples. European economies and communities were the ones that mostly benefitted from their arrival in the Americas and from the Atlantic slave trade network.” Using this article and other articles and videos in this lesson, find evidence that supports, extends, or challenges this claim.
Now that you’ve learned more about the transatlantic slave trade, reflect on what you’ve learned and how it informs your life today.
This sourcing activity can be especially valuable because it shifts the focus from the injustices that took place and onto the words of the people who explained and justified it.
You can also have students view a two-minute video from historian Camilla Townshend on the importance of Aztec sources. Find the link and more in this community post.
It may not be surprising to learn that there are differing perspectives when it comes to the Spanish conquest of the Aztec Empire. Analyze the words of an Aztec poem to that of Spanish conquistador Hernán Cortés to come to a deeper understanding of this event.
Colonial society in the Americas had a reputation for being strictly hierarchical, with race playing a big role in who held power, while rigid gender roles limited opportunities for women. The story of Sor Juana Inés de la Cruz suggests things were sometimes a bit more complex.

Preview the questions below, and then skim the comic, paying attention to things like prominent colors, shapes, and types of text and fonts. How do you know where to start and in which direction to read? What’s in the gutters (the space between panels)? Who or what is the focus of the comic?
While you read
Look for answers to these questions:
- When and where was Sor Juana Inés de la Cruz born?
- When Juana was a young girl, what did she first learn?
- Where was Juana working and living when she was seventeen years old? What controversial writing did she complete at this time?
- What decision did Juana make so that she could continue studying? How did this decision cause problems for her later?
- How does the artwork help us to understand the unique circumstances that shaped Juana’s life, particularly her dual heritage?
After you read
Respond to the following questions:
- Using evidence from this graphic biography, explain how Sor Juana’s story supports, extends, or challenges the social categories and roles you’ve learned about in this era.
- What evidence does Sor Juana’s biography provide about how people lived in the colonial Americas in this period? How does this evidence support, extend, or challenge what you have learned about the impact of the Columbian Exchange in this region?
Human vs. AI Research Battle: The Significance of Foods
- Have students list foods that spread during the Columbian Exchange, and then prompt AI to expand it.
- Next, have students ask AI which one food had the greatest historical impact.
- Finally, challenge students to do some of their own research to evaluate and critique the AI response.
What makes this effective? Students get to learn about historical significance using AI as a research partner. But rather than simply accepting the AI results, they use their own research to challenge or confirm its responses using evidence they gather, providing a valuable exercise in information literacy.
