Tenth graders conduct various activities utilizing the scientific method to formulate a hypothesis, conduct a controlled experiment, collect and analyze the data and communicate their results through a poster. They also identify...

Learners examine the structure of ecosystems. In this ecology lesson, students listen to a lecture on relationships among organisms and biomes. Learners use the information to create ecosystem organization pyramids.

Junior biologists compare the amino acid sequences from fragments of five different globin molecules. They count the letter differences between each species pair. They construct a graphic representation of the evolutionary relationships...

A pool of brine in the deep sea can be up to four times as salty as the surrounding sea water. The deep sea ecosystem relies on chemosynthesis and the organisms that live there are often strange to us. The instructional activity focuses...

Students identify the different organisms in the food web. In this biology lesson, students create food chains using the information on cards. They explain what happens if an organism is removed or added in the web.

Students seek scientific and technological solutions to envrionmental problems. They record class activities in a journal. They identify relationships among living things and their environments.

Fourth graders explore relationships among organisms involved in ocean food chains to investigate interdependence of the organisms.

Searching for an activity that allows emerging biologists to explore symbiosis up close and personal? Pupils collect samples and view lichens through a microscope and conclude with a discussion about the relationship they have...

Third graders role-play various organisms from a food chain to illustrate how a food chain works. In relay style, 3rd graders fill their cups (stomachs) and, in turn, fill a larger organism's cup (stomach) to visualize the importance of...

Learners of many ages discuss how all organisms rely on other organisms for their survival. They construct a food web and energy pyramids, and write an informative essay about the food web that they have designed.

How can you encourage pupils to demonstrate creativity while still meeting the objective of applying technical knowledge? This activity is your answer! Scientists will create an imaginary creature and prepare a graphic organizer with...

Students examine the rich array of marine wildlife that lives in waters surrounding the Indian subcontinent. They explore the relationships among organisms in coral reefs. They explore environmental dangers to coral reefs and research...

Students describe major features of cold seep communities, and list at least five organisms typical of these communities. They infer probable trophic relationships among organisms typical of cold-seep communities.

Young scholars role play predators and prey, classify organisms as predator or prey, and describe factors that affect population growth and size.

Seventh graders research types of symbiotic relationships on the Internet and explain what the effects would be in one of the species disappears.  In this investigative lesson students use the Internet to do research then...

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

Students explore pond ecosystems. In this living environment lesson, students observe the local pond and identify the living things they find by drawing pictures. Students observe organisms that were found in the pond by using a...

Students explore the different habitats in the Balkan peninsula. In this ecology lesson plan, students research about a species and create a 3D diorama of its environment. They present project in class and share their research findings.

Students consider that under certain conditions in nature tend to remain the same or move toward a balance. They observe populations and determine the functions (e.g., de-composers, producers, consumers) they serve in an ecosystem. They...

Producers, herbivores, carnivores, omnivores, decomposers. To begin a study of the forest ecosystem, learners examine the connections among the members of ecological communities.

Students discuss how organisms relate to one another. They work together to research a specific organism and how it relates to other organisms. They present their findings to the class.

Students examine the relationship between humans and grizzly bears. In this biology lesson, students research about the bear's habits and living environment. They write a letter to the US Fish and Wildlife Service petitioning them to...

Do your pupils have the misconception that environmental predators are "bad" and harm smaller creatures? The simulation explains, in detail, the important role predators play in maintaining a stable ecosystem. Through web-based research,...

Biology aces analyze restriction maps to determine the relationships among different primate species and then complete a cladogram. Preface this lesson with an explanation of how restriction enzymes are used to create the DNA maps....
