Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

Young scholars gain an understanding of the concept of Diaspora relating to Greeks. They use guided discovery to apply the geographic inquiry model to an examination of the reasons for Greek Diaspora.

Third graders examine how an ecosystem is a distinct community of interactive living and non-living things.

Learners examine the connection between the habitat needs of endemic species to the habitat needs of humans.  In this habitat lesson young scholars research the habitat requirements of a given family then develop an idea to improve...

Read an exciting science mystery about killer bees online, evaluate a list of clues, and try to answer the questions correctly. The story responds to the reader's choices and presents research material for the next step. Though the...

Students create a sustainable, self-contained ecosystem in a ten-gallon aquarium.

Twelfth graders explain relationships and interactions between species, the difference between a fundamental niche and a realized niche. They explore the various species interactions from their classmates through the jigsaw activity.

Students are able to answer basic questions about the region and the use of natural resources, sketch a mental map of the story's setting, and find their way through the thematic maze/map.

Students pick an ecosystem (forest, desert, coral reef, open ocean, grassland, mountain, savanna, etc.) and design an interaction web for their chosen ecosystem. Each group shares their ecosystem's web of life with the class.

Eighth graders design posters of working ecosystems using pictures from magazines. They label autotrophic, heterotropic, or saprotrophic energy sources, and identify predators and prey.

Third graders recognize and examine ecosystems. They observe and describe habitats within ecosystems and observe and identify organisms with similar needs that compete for resources.

Students investigate the environment by participating in a class trip. In this pond ecosystem lesson, students define a list of vocabulary terms associated with ponds such as invertebrate and metamorphosis. Students attend a field trip...

Young scholars study the flow of water in the environment.  In this water cycle instructional activity students evaluate the consequences of changes in the water cycle using data. 

Learners explore environmental awareness by completing a construction project. In this biomes instructional activity, students identify the different elements for life to thrive in an ecosystem. Learners utilize a cardboard or wood box...

Students hike a local mountain and examine its life zones. They measure various components at each zone and collect leaf litter at the sites. At the mountain top, students make descriptive observations and complete a handout about the...

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 investigate the physical, chemical and biological parameters necessary to establish an ecological baseline. Establishing an ecological baseline not only shows the ecological characteristics of a creek but makes the possible...

Seventh graders engage in hands-on experiments and activities dealing with rivers and greenways. They also observe lectures and demonstrations by experts in water and river restoration. Students and teachers participate in canoe trips...

Participate in a life science unit that examines the relationships of living organisms to each other and to their environment as well as the student's role in the cycle of life. Through hands-on activities, research, and scientific...

Students examine the evidence that scientists have used to support the existence of global warming and the greenhouse effect. How the concepts have been developed and evaluated form the focus of this lesson.

Eighth graders define what an ecosystem is, what its make up is and how pollution effects it.  In this air pollution lesson students identify the cause and effects of pollution on an ecosystem and trace a food chain. 

Ninth graders complete a unit of lessons on ecosystems, organism interactions, and energy flow. They create a key for known species of fish, diagram the movement of energy through an ecosystem, and create and present food chains and food...

Fourth graders are introduced to the concept of ecosystem; specifically, the interrelationships among plants and animals within an ecosystem, and their relationships to the environment in which they live and interact.

Sixth graders examine the factors that influence the stability of ecosystems. They construct a miniature ecosystem in a jar that includes plants, small fish, and snails, record the population changes over a period of four weeks, and...
