Use a video and a diagram to discuss beaver lodges and dams.
• Have students watch the video “Animals Can Build It!” Ask: Why do animals need homes? What benefits does a home provide? (protection from predators, sheltered places for babies to grow, a place to store food, etc.)
• Have students review the “Inside a Beaver Lodge” diagram on page 5. Explain that a beaver home is called a lodge and that beavers also build dams. Compare the functions of the lodge (to be a home for the beavers) and the dam (to slow down water flow and create a pond where beavers build their lodge).
