• 1. Build background about types of plants and animals.

    Draw a 7-column chart on the board with the following headings: Plant, Invertebrate (animals without a backbone), Fish, Bird, Reptile, Mammal, and Amphibian. Have students cut out photos, pictures, or other representations of each type of organism, and tape them in the correct columns.


    2. Compare living things in the Gulf of Mexico.

    Project the MapMaker Interactive and point out the Gulf of Mexico to students. Then download and display the Layers of Life diagram from the October 2010 issue of National Geographic magazine. Explain to students that the Gulf of Mexico is home to many species of plants and animals. Ask students to identify each type of organism on the Layers of Life diagram as one of the seven types of organisms. When students properly identify a plant or animal, point out some of the features of that organism; for example, if students identify the brown pelican as a bird, point out that birds have feathers and wings to help them fly. Then make a hash mark or write the name of the organism in the correct column on the chart.


    3. Discuss the types of living things students identified.

    After the class has sorted all of the organisms, count the number of organisms in each column. Ask: Which group has the most organisms in it? The least? Then summarize the information for students by restating that there are many different types of plants and animals living in the Gulf of Mexico. They are all part of the food web. As humans, we are also part of this food web. It is important to try to keep this ocean environment clean so that all of these plants and animals stay safe and healthy.

  • Background Information

    The Gulf of Mexico is home to a wide variety of organisms. There is a high diversity of life because of the multitude of different marine ecosystems and the temperate waters of the Gulf. Ecosystems include freshwater and saltwater marshes, mangrove forests, coral reefs, and open ocean communities. This makes the Gulf of Mexico one of the most productive marine ecosystems on Earth.
