Lesson Two: Objectives
By the end of this lesson, students should be able to:

    • Recognize environmental concerns that threaten Arctic ice.
    • Identify how species may become threatened or endangered, specifically Polar Bears
    • Explain how fewer resources are used when, reusing, or conserving.
    • Explain how people can preserve the environment.

Show children on a map or a globe the North Pole. Explain that the
North Pole is always frozen with ice, but as5605.gif because of something called
“carbon emissions,” temperatures around the world are getting warmer, which is causing the polar ice cap to melt. Give each person an ice cube to hold in his/her or hands, and let them see what happens when it gets warmer. Explain that as the ice is melting it turns into water. When the
ice at the North Pole melts, the water goes into the sea, and it is
starting to raise the level of the sea.

polar-bear-on-melting-iceberg.jpgTo demonstrate what happens when the ice melts, have children pretend to be polar bears. Explain that polar bears live on the ice. When they hunt for food (seals), they travel across the ice floes. They swim from ice floe to ice floe. Polar bears are facing a big problem. Because the ice floes are melting, the bears must swim further distances to get from ice floe to another, which is very exhausting. The bears tire out easily before they can find food for themselves and their cubs. Use pages of newspaper or construction paper to represent ice floes. Play some music and have children move around, jumping from one ice floe to another. Stop the music periodically. Each time remove one ice floe— explain that the “ice” is disappearing because the temperature is getting warmer. As you remove the “ice floes,” it will get harder and harder to find somewhere to stand. Players are out if they cannot get on a piece of ice. Explain to children that polar bears are experiencing the same problem.

Show the class a video about Endangered Species. Note
that students may need to view this segment more than one time in order to fully grasp the concept. Say: In this video, we will see some animals that are in danger of no longer existing. Watch the video to find out
why these animals are in trouble.


Have students think about what they learned from the video. Provide students with the graphic organizer below. Have students record their answers in the "My Answer" column. Then have them share their answers with a partner. Have them write their partner's answer in the "Your Answer" column.

Ask students to think about some ways the environment around their house can be harmed. Remind students that environmental problems like pollution, using too many resources and wasting energy can occur right around their homes. Ask students: What activities do you do that could cause these environmental problems around your home? What do you any your family do to help protect the environment? Ask students what other questions they have about protecting the environment. Write a list of student- and teacher-generated questions on a board or chart paper for reference throughout the lesson.
