Busy As a Beaver . A video will be used to reinforce their observations and to show interesting uses of air, such as sailing, raising a roof, and parachuting. Students will use the science process skills of observing, hypothesizing, experimenting, measuring, and recording data. The lesson will take approximately two hours and can be broken up into shorter segments. The beaver is a North American animal that protects itself by being a builder.
Beavers build dams that create ponds.
The water of the pond surrounds the beaver lodge and this is protection from predators for the beaver. In this video lesson, students will learn about the physical characteristics of beavers and will see how they construct their dams and lodges. They will learn that a beaver dam can raise the water level of a pond by a meter or more. The lesson should take about 45 minutes. In preparation for this lesson, the teacher should make a lesson outline chart that will be taped to the top of the television screen and hang in front.
