Understanding GMOs and Hybrid Species: A Classroom Activity

In this lesson, students will engage in a hands-on activity exploring the differences between hybrid species and genetically modified organisms (GMOs). The session begins with gathering materials and assigning homework, followed by a discussion on the implications of GMOs in nature. Students will create their own GMOs through a foldable project, answering key questions about their designed organisms. This interactive session aims to foster critical thinking about biotechnology, species hybridization, and environmental impact.

  2. HYBRID vs GMO DO NOW: 1. What is a hybrid species? Explain and give an example. 2. What is a GMO? Explain and give an example.

  3. Hybrid Species: A Cross of Two Similar Species (can occur naturally)

  4. Zebroid

  5. Grolar Bears

  6. GMOs: Organisms with Manipulated DNA (may have pieces from one or more other species – could never breed in nature)

  7. People are concerned about GMOs hybridizing with already existing species!

  8. Read Aloud: GMOs hybridizing with native species • If genetically modified organisms cross with native species, they will create a new hybrid species that will have some genetically modified genes. • These hybrids might spread and out-compete, or “take over” in place of the native species. • The hybrids will have no natural predators. If Glofish were to escape and cross with natural species, sharks would not recognize these bright fish as a food source. • These new hybrid species might be unsafe! They might be aggressive, or dangerous to eat.

  9. Answer Discussion Question: 5 minutes

  10. Create your own GMO (Foldable) Left Section (small): What would your GMO be able to do? Why is it helpful or cool? Middle Section (big): What would it look like? Draw a picture (in color!) Right Section (small): Where would its genes come from? (other species, specially designed?)
