Lesson Two: Objectives
By the end of this lesson, students should be able to:
    • Describe how various organisms have adapted to their habitats.
    • Compare and contrast traits of organisms from different environments.
    • Explain how Arctic species respond to environmental changes
    • Explain how humans adapt for survival in an Arctic environment

Engage: Activate Prior Knowledge; Generate Interest

Activate Prior Knowledge

Begin the session by asking students to name some basic needs of living things. Students should explain that organisms need to take in food and energy and get rid of wastes. If necessary, remind students that organisms must live in an environment that meets their needs. Use this discussion to judge what students already know about how living things survive.

Then show students the video segment How Plants Adapt (0:00 to 1:12).
Point out that the artic poppy, like other plants, needs sunlight to make food. Ask the class, “What trait helps the arctic poppy get sunlight? Why is this trait important in the arctic environment?” (You might need to briefly discuss what the term “trait” means and use it in describing features or behaviors of the students themselves.) Explain that the movement of the plant to face the sun is an example of an adaptation. This adaptation helps the plant live in a place with limited sunlight.

Hands-On Activity

Conduct the first part of the hands-on activity, Hiding in Plain Sight in which they search for hidden fish around the room. Have students record their findings in their notebook. During the Explore stage, have them conduct the student part of the activity.

Explore: Allowing Students to Experience Content

As the second part of the Hands-On Activity, Hiding in Plain Sight, you can have students create their own fish either as a whole group or center activity.

Have students complete the Exploration Adaptation in small groups. Students should consider how the traits of each organism in the activity increase or decrease its chances of survival. Then ask students to predict what would happen to the polar bear if its environment became warmer. How might it adapt? What would happen if it couldn’t adapt? Use this discussion to emphasize that adaptation is essential for a species’ survival.

Have the students read the two articles on Discoverykids.com regarding Polar Bears. Students should use the graphic organizer to collect information about adaptations of polar bears.
