Harsh Continent

Suggested Activities

1. In recent decades, scientists have begun to assess the impact of human actions on the environment. One of the areas that has been most studied is the Ozone Layer. In 1985, scientists made some startling discoveries about disappearing ozone in the Antarctic stratosphere. Challenge your students to learn more about the research surrounding the Ozone Layer and Ozone Hole. Have students work in groups to collect information and report their findings. Why is the condition of the Ozone Layer of any significance to life on Earth? What are scientists currently saying about the status of the Ozone Hole? Discuss.

2.Your students may be interested to know that no one country governs Antarctica. This is one stipulation of the Antarctic Treaty. The Antarctic Treaty has been one of the most successful international agreements ever made. It took effect in 1961 with signatures from twelve countries and it deals with issues regarding the future of Antarctica and its exploration. Direct students to online copies of the treaty (See Resources) to read. Ask students if they would add anything to, or delete anything from the agreement. Have students speculate as to why the treaty has been so successful, and to what other places and circumstances such a treaty could be applied.

3. Ice and snow cover 98% of Antarctica, yet some species of plants and animals thrive there. Challenge students to find out how these species survive in such a harsh environment. Divide the class into small groups. Direct each group to choose one plant or animal species native to Antarctica or its surrounding waters and research the biological adaptations that enable it to live in that environment. Have each group prepare a report, video presentation, or Web site that presents its information.
