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

Students see that spiders catch and eat their prey and are also caught and eaten by their enemies. They sort the pictures into animals that spiders eat, those they do not eat, and those that are spiders.

Students research about the importance of sea ice to world climate and sea organisms. In this earth science instructional activity, students create a model of present and future Arctic sea ice communities. They discuss how ice melting...

Seventh graders examine the factors that affect the number and types of organisms that an ecosystem can support.  In this ecosystem lesson students study the barn owl and where it is on the food chain, then dissect an owl pellet.

Second graders observe, discuss, and record the requirements of a healthy environment for both arthropods and people by designing and maintaining an artificial habitat for an arthropod, and considering the requirements for a healthy body...

Students understand what physical adaptations are and how they help an animal to survive. In this adaptations lesson, students research four animals and then make an original animal that has adaptations to make them survive.

Students maintain a field journal as they follow penguin parents raising their chicks during the breeding season. They formulate testable questions. Students reflect on animal behavior in the field related to survival and chick rearing.

Students explore biology by creating a report for the class. In this oceanography lesson, students research and identify the survival characteristics of a list of freshwater animals by utilizing the Internet and library. Students...

Sixth graders continue their examination of the state of Connecticut. After taking a field trip, they identify the types of birds, plants, invertebrates and vertebrates who make their home in the salt marshes. In groups, they identify...

Students use field research and traditional research to identify migrating species of birds as well as their migratory patterns. Students generate a list of questions regarding migration and a plan to research the questions. A field...

Students create a collage. In this animal classification lesson, students discuss why and how scientists classify animals. Students view pictures of different animals and decide which class each animal belongs to. Students compare...

Third graders explore the interdependence among the plants and animals in natural communities.

Pupils research where in the world coral reefs are located. In this ecology activity, students create food chains and food web. They simulate growing coral reefs to understand their characteristics better.

An ecosystem is really just the flow of energy through many different living organisms. A study of Rudyard Kipling's The Jungle Book leads to an environmental science activity in which learners study how various factors can affect...

Students use various web sites to access information about the rain forest. They use the Tropical Rainforest Interactive CD to make their own rain forest pictures and stories and learn facts about the rain forest. They use various books...

First graders research ocean animals and plants on the web.  In this ocean habitat instructional activity, 1st graders prepare a multimedia presentation.  Students will work on their presentations in pairs and every group...

Students investigate the worm and the cockroach. In this organisms lesson, students visit suggested websites to identify the characteristics of worms and cockroaches.  Students dissect a worm and observe a live cockroach. Students...

Students watch an episode of "Nature" about the "Big Red Roos." They create food chains and webs based on the information they've researched on the red kangaroos. They write an editorial on the topic of the killing of kangaroos in the...

Students participate in an online whale watching game. They identify the reasons for migration and describe the route. They make predictions on what would happen if the ways did not migrate.

Sixth graders complete a five-week unit investigating the eight major biomes of South America. They conduct Internet research, collect short-term and long-term climate data, and create a HyperStudio slideshow stack about a selected biome...

Learners research phytoplankton and zooplankton. In this food chain lesson, students read This is the Sea That Feeds Us and discuss plankton, food chains, and webs. Learners define phytoplankton and compare them to land plants....

Students examine how animals protect themselves from predators and camouflage themselves. They participate in a simulation in which they locate red and green yarn "caterpillars," organize their data, and generate a bar graph using...

Students examine why certain animals live in only specific places throughout the world. Using animals, they classify them based on their characteristics and identify their basic needs. They also observe and compare the life cycles of...
