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...

Emerging ecologists need a full understanding of life, from the inner workings of a cell to the complex relationships among organisms. This examination is meant to assess high schoolers after an entire year of courses on the living...

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...

Is it a producer, carnivore, omnivore, scavenger, or decomposer? Different relationships among organisms are explored here. It is a simple, multiple choice assignment. Use it as a quick warm-up or quiz.

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...

The living environment, from the interior of a cell to the complex relationships among populations, is queried in this final examination. Learners examine air pollution maps, cell diagrams, population graphs, and drawings of cells. They...

In this evolution worksheet, students will determine the evolutionary relationships among organisms using cladograms and phylogenetic diagrams. This worksheet has 13 short answer questions and 3 multiple choice questions.

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...

Birds help other birds find food? Scholars are placed into one of five groups of different birds. Each group then "feeds" on letters of paper in a field and gather five pieces per person. As each group plays, more food is exposed,...

In this living things worksheet, students review terms and concepts about the different relationships between living things. This worksheet has 7 true or false and 5 short answer questions.

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...

It's a jungle out there! Young biologists journey to Darien, Panama to examine the intricate relationships between the organisms that inhabit the jungle. Groups begin by demonstrating an understanding of energy flow in ecosystems, then...
