Why Lesson Planet?
Students use ice cubes to demonstrate how the polar ice caps are melting and how it effects the polar bears. In this polar bear lesson plan, the teacher explains how polar bears live on the north pole and how they are having trouble due to global warming. Then each student gets an ice cube and observes how it melts in their hand. After the observation of the ice cube, the students discuss what they could do to save energy and help the polar bears.
