1. Build background about the 2010 Gulf of Mexico oil spill.
Distribute the handout Oil Spills in Marine Environments for independent or small-group reading. Answer any questions students may have about the information.
2. Discuss biodiversity and habitats in the Gulf of Mexico.
Download and show students the Layers of Life diagram that accompanies the map, Gulf of Mexico: A Geography of Offshore Oil, from the October 2010 issue of National Geographic magazine. Explain that the Gulf of Mexico is home to many species of plants and animals and that many organisms found within Gulf of Mexico ecosystems were adversely affected by the oil spill. Ask: What are the different types of ecosystems found within the Gulf of Mexico that may have been affected by the spill? What animal and plant life was affected by the spill? Tell students that cleanup crews worked to rescue, rehabilitate, and occasionally relocate affected wildlife.
3. Watch a video about sea turtle relocation.
Have students watch the National Geographic video about sea turtles and the oil spill: “Gulf Turtle Eggs Relocated.” As they watch, ask them to record the names of specific locations they hear mentioned in the video, and jot notes on what happened at these locations. Then have students use the map Gulf of Mexico: A Geography of Offshore Oil to find some of those locations. For example, students should be able to find the place where loggerhead turtle eggs were relocated from and the place the kemps ridley sea turtles were relocated to and released from. If students have difficulty, tell them that Gulf Shores, Alabama, is located by Bon Secour National Wildlife Refuge, and point out the Canaveral National Seashore. Ask: What reasons were given to justify why it was an appropriate strategy to relocate turtles to the Atlantic coast? What is the likely outcome for young turtles that were not relocated from the Gulf coast to the Atlantic coast around this time?
4. Read about oiled birds.
Have students read the National Geographic News article “Oil-Coated Gulf Birds Better Off Dead?” Answer any questions they may have about the reading.
5. Have a class discussion about care for impacted wildlife.
Have a group discussion or debate about the pros and cons of rescuing, rehabilitating, and relocating wildlife. Use the following questions to prompt students to synthesize what they have learned, and also to discuss their opinions:
- Do you think it is humane to try to rehabilitate these animals? Why or why not?
- Do you think it is our responsibility to try to help wildlife when humans are the source of the problem? Why or why not?
Ask each student to use the discussion points to write a persuasive essay that answers the guiding question: After oil spills, should humans rescue, rehabilitate, and/or relocate wildlife? Students should support their argument with facts they learned over the course of the activity.
Assess students’ persuasive essays based on organization, content, and voice.
Extending the Learning
Have students track migrating sea turtles that are radio tagged on the Sea Turtle Conservancy website to see turtle migration in action.
Subjects & Disciplines

Ocean Literacy Essential Principles and Fundamental Concepts
- Principle 6e: Humans affect the ocean in a variety of ways. Laws, regulations and resource management affect what is taken out and put into the ocean. Human development and activity leads to pollution (such as point source, non-point source, and noise pollution) and physical modifications (such as changes to beaches, shores and rivers). In addition, humans have removed most of the large vertebrates from the ocean.

Our increasing reliance on oil and petroleum products has resulted in multiple marine oil spills at offshore drilling sites and from transport vessels. Oil spills are detrimental to the health of marine environments and marine organisms. After environmental disasters like the Deepwater Horizon oil spill, scientists and volunteers rescue, rehabilitate, release, and sometimes relocate affected wildlife. Sea turtles and oiled birds are two of the most common animals that are rescued. Scientists relocate organisms to prevent future contamination of individuals and to help preserve a species.
