Fourth graders, practicing scientific method, identify specific attributes to various oyster shells.

Students visit a wetland ecosystem. While they are there, students explore how to read topography maps of Rose Bay.

Students visit a local park to test the quality of the aquatic environments. They search for sources of pollution and examples of pollution control. Based on their obeservations and experiments, they rate their local environment.

Students share their prior knowledge of the elements of the environment. In groups, they are introduced to the concepts of biotic and abiotic factors in a specific environment. They discover their effects on organisms living in the...

Pupils begin the lesson by researching the history of City Point, Connecticut. Using a map, they color areas they were asked to find and discuss why the areas are important to the community. As a class, they are shown recent slides of...

Students recognize interdependence in a food web by using yarn and notecards to create a food web and discussing what would happen if one of the organisms from a certain trophic level is removed.

Students create a plant or animal that would be well adapted to a habitat they selected. They first learn about Mangroves and their specific adaptations that help them survive in their habitat.
