In this lesson, students will explore a fully developed Kialo discussion on the question “Could the De-Extinction of Certain Species Help the Environment?” The discussion examines how bringing extinct animals back to life could help preserve our environment, as well as the difficulties and risks that could arise from de-extinction.
Through the Kialo discussion, students will be introduced to balanced perspectives on the topic of de-extinction so that they can form their own opinions. In class, students will then take part in a “Four Corners” group activity. Within these groups, students will work together to justify and share opinions with the class.
Student learning will be assessed through an individual argumentative essay, which will build on the “Four Corners” activity.
In this lesson, students will:
- Identify the potential advantages and risks of animal de-extinction.
- Compose a series of reasons to justify their opinion on the de-extinction of a certain species.
Students should have familiarity with biodiversity, ecosystem interactions (including food webs and abiotic factors), evolutionary adaptations, cloning, and genetic engineering.
- Make 1 clone of the discussion for each class.
- If it is important for students to see each other's comments in real time, give them Writer permissions when inviting them to the discussion.
- If it is only important that you see students' comments, give students Suggester permissions when inviting them to the discussion.
The Kialo discussion “Could the De-Extinction of Certain Species Help the Environment?” (also embedded below.) This consists of:
- A brief background on de-extinction
- A fully developed Kialo discussion for students to explore. The discussion examines the potential benefits and drawbacks of animal de-extinction.

- At-home preparation: Exploring the Kialo discussion (approx. 30 minutes)
- Opener (5-10 minutes)
- Part A: Four Corners (25-30 minutes)
- Part B: Preparing to write an argumentative essay (8-15 minutes)
- Optional closer (2 minutes)
Students will write an individual argumentative essay on the prompt, "Should Scientists De-extinct the Woolly Mammoth?" (see suggested rubric).
At-home preparation: Exploring the Kialo discussion (approx. 30 minutes)
To prepare for this lesson, direct students to explore the cloned Kialo discussion "Is De-Extinction Worth the Cost?" at home. Students should spend about 30 minutes on this task and write down any questions or comments under any claims that they would like to discuss in class.
Opener (5-10 minutes)
Instruct the whole class to turn to a partner and discuss their answers to the following question: “What is your favorite extinct animal? If you could bring it back to life, would you?” Conduct a brief discussion around students’ answers.
- Go over any questions or comments about the Kialo discussion that students made at home, then lead a brief discussion around these points.
Part A: Four Corners (25-30 minutes)
- Post a sign in the four corners of the room, reading “Strongly Agree,” “Agree,” “Disagree,” and “Strongly Disagree.”
Explain that students will now do an activity called “Four Corners.” Students will go to the area that corresponds to their level of agreement with the statement “Scientists should de-extinct the woolly mammoth.” Students who strongly agree with the statement will go into the area labelled “Strongly Agree,” and so forth.
- Once students are separated into their areas, tell students to choose a group recorder to help write down the group's reasons for picking their opinion. Groups will have 10 minutes to discuss and write. After the 10 minutes are up, a group representative will then share the group’s reasons with the whole class.
Part B: Preparing to write an argumentative essay (8-15 minutes)
Explain that students will write an individual argumentative essay on the prompt “Should scientists de-extinct the woolly mammoth?” to demonstrate their new knowledge on the topic. Tell students to consider the following factors as they argue their position:
- The potential environmental impact of de-extinction.
- The technology involved in de-extinction.
- The risks of de-extincting an animal.
- The investment (money) that de-extinction requires.
Distribute and go over the assignment rubric. If time permits, direct students to begin planning their essays.
Optional closer (2 minutes)
- Remind students that species are constantly going extinct, and there have been many tragic extinctions over the last century. Share this video footage of some now-extinct animals for students to contemplate: https://www.youtube.com/watch?v=RF_RxCWxyfw
