Students construct flow diagrams of the carbon and nitrogen cycle processes. They identify sequences in each cycle that are affected by human impact and present their research to the class.

Young scholars discover the concept of decomposition. They examine how it makes the soil more fertile and how it helps plants. They put a compost bin in their backyard and record their observations.

Young scholars develop an understanding and appreciation of water purification techniques and their implications for health maintenance.

Second graders examine two-dimensional shapes using their characteristics. In this shapes lesson, 2nd graders identify similarities and differences by using cut out shapes, diagrams, mirrors, and graphic organizers.

Students investigate the decomposition process and the parameters which influence the rate at which it occurs. They design a "controlled" experiment by comparing decomposition rates between two compost piles. Analysis questions include...

Students design and conduct investigations that illustrate the effect bioremediation has on organic matter and determine environmental applications. They, in groups, present their findings to the class.

Students recognize that plants and soils have a close relationship. They view a photo essay on the common practice and natural process of composting. Afterwards, they observe the process of plant decay over the course of several days.

Students explore the physical characteristics, distribution and habitat of termites. The lesson focuses on the termite as a social creature contrary to most other insects.

Students participate in an experiment in which they test the growth of different types of plants. They discover how growth rates vary using inoculum. They draw pictures and are read books about plants to end the lesson.

Young scholars work together in groups to report on different topics related to decomposition. They answer questions and share their answers with the class. They discuss any topic that is unclear.

Students examine the following concepts: If water supplies contain materials which rot or decompose, oxygen is used. Decay and decomposition require vast supplies of oxygen. The use of oxygen for decay of wastes may be a life or death...

Sixth graders complete a variety of activities to explore both positive and negative effects of microorganisms. They, in groups, engage in a series of experiments which illustrate the effects of certain molds.

For this unit of lessons, students examine the role of compost columns and recycling. They create a KWL chart about garbage in Chicago. They also examine life cycles and packaging of everyday products.

Students write the electron configuration of elements using the Aufbau principle. In this chemistry lesson, students build their own key that demonstrates the principle.

In this living organisms worksheet, 6th graders choose the multiple choice answer to 10 questions. Students then read and answer 10 statements as true or false and fill in the blanks to 5 statements.

Merge chemistry with environmental science to study biodegradable materials. An engaging activity allows learners to experiment with different resin concentrations and composites. Through experimental tests, scholars test their creations...

Students go on an outing and note garbage near picnic tables. They brainstorm ways to be involved with anti-litter campaigns and write letters to local officials.

Students create environments to demonstrate how earthworms interact with their surroundings.

Students complete a food chain. For this ecosystem lesson, students learn about producers, consumers and decomposers. Students identify herbivores, carnivores and omnivores and complete two worksheets.

Fifth graders participate in activities during a visit to Central Park. In this urban life lesson, 5th graders visit Central Park where they explore pond dipping, stream chemistry, and play a native plant Bingo game.

Sixth graders discover the various habitat requirements for assorted household pests from ants to wasps. They conduct various activities including researching the life cycles moths, cockroaches, and mosquitoes

Students observe a composting box. For this soil lesson, students create a composting bin by using a bin, newspaper, worms, and food scraps. Students create a composting food web.

Young scholars study bacteria and the role it plays in the ecosystem.  In this bacteria lesson students research the roles bacteria has and submit a chart. 

Learn how scientists classify different types of organisms in an ecosystem or in a food chain by their role and function as either a producer, a consumer, or a decomposer. Then play a game that tests your understanding of these important...
