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.

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.

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.

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.

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.

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.
