Sixth graders examine the fresh water ecosystems. In this environmental lesson, 6th graders work in groups to collect information about a fresh water ecosystem and report their findings to the class in the form of a brochure.

Students compare and contrast fresh and salt water coastal environments. After describing how sea animals adapt to their habitats, they design a variety of sea creatures and explain how the adaptations aid in the animals' survival. ...

Learners study a variety of global wetland habitats, their similarities and differences. They examine the variety of life that such wetlands support and determine that many animals and plants are adapted to life in wetlands, that...

Third graders identify sources of salt water and fresh water that enter the Chesapeake Bay. They build a model watershed and describe how runoff enters the Bay.

Fourth and fifth graders explore soil by taking a simulated field trip under the earth. They go to an Internet site that runs a simulation which charges them with finding a source of pollution that could destroy all of Earth's soil, and...

Students create a pond habitat inside and outside their classroom. In this pond lesson plan, students create a habitat with animals, water, and plants in order to create a proper pond habitat.

Fifth graders investigate biomes of the earth. In this biomes lesson, 5th graders explore eight different biomes which include the tropical rain forest, deciduous forest, grasslands, and taiga. They design an artistic scrapbook that...

Middle schoolers demonstrate how water flows by building a human watershed using themselves. In this ecology lesson, students compare and contrast point-source and non-point source pollution. They write what they have learned from this...

Third graders examine the difference between a food web and food chain. They also examine the importance of the sun in a food web and food chain. Students understand what happens when you remove parts of the chain.

Students create a simulated self-sustaining ecosystem. In this biology lesson, students examine the different food chain and ecosystems in their model. They recommend some improvements and changes to an existing ecosystem.
