Students apply the ecological pyramids of numbers and biomass with an activity using topographic maps. In this trophic level lesson, students work in groups using a topographic map to determine the number of organisms that can live in an...

Environmental science enthusiasts show what they know at the end of the year by taking this full-fledged final exam. They answer multiple-choice, graph interpretation, and essay-analysis questions, 73 of them in all. Topics range from...

The bulk of this instructional activity involves the construction of both an aquatic and a terrestrial ecosystem in which to observe trophic relationships. Detailed directions are provided, as well as discussion questions, and assessment...

Some organisms spend their entire lives in leaf litter. The third in a series of six is a great lesson exploring the community of leaf litter. Groups gather and then spread leaf litter over white paper and remove leaves/twigs while...

The reintroduction of a species to an area doesn't always go as expected. Scholars learn about the reintroduction of wolves into Yellowstone National Park with a video, reading, and discussion questions. They complete a hands-on activity...

A lab activity is a great way to incite thoughtful questioning and scientific processes. Pupils will collect organisms with a Petri dish, make observations, sketch the organism, ask questions, then attempt to identify the specimen...

Students discuss the concept of a food chain in the California ecosystem. in this food chain lesson, students look at different cards and sort them into herbivores, carnivores, decomposers, and omnivores. Then they use these cards to...

Students learn about demographic population pyramids. They then design and fictitious nation and draw its population pyramid.

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...

In this food chains worksheet, students complete a crossword puzzle by placing 16 terms into the puzzle that match the clues given. Students review food webs, biomass pyramids, and the water cycle.

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

Students study population distribution and survivorship curves by collecting data regarding age of death of humans from either tombstones, newspapers, or other community resources. Students analyze data by creating graphs and population...

Students compare and contrast abiotic and biotic factors. They discuss how these factors effect ecosystems. They answer questions to complete the lesson.

Students identify the main concepts and ideas of the nitrogen cycle. They review key concepts covered up to this point in ecology including food chains, food webs, energy pyramids, and bio-geochemical cycles.

In this ecoregions of Texas worksheet, students complete a summary of a particular ecoregion in Texas. They find the producers and consumers of the region, they draw a food chain, the draw a food web, and they complete an energy pyramid...

Students explore the interrelatedness of predators and prey in four different activities. They simulate an aquatic insect, fish, and osprey food chain during a poker chip game, play an M&M game to simulate the relationship between...

Students compile data on population distribution and develop survivorship curves using information from cemetery tombstones and obituaries. They develop inferences on the changes in population age distribution in their area over time.

Students recognize interdependence in a food web by using yarn and notecards to create a food web and discussing what would happen if one of the organisms from a certain trophic level is removed.

Students create visual representations of ecosystems. In this ecology lesson, students discuss the interdependence of plants and animals in various ecosystems. Students cut pictures from magazines and glue them on sturdy blocks. Using...

Students understand ecological systems. They provide experiences to assist citizens to increase their sensitivity and stewardship for the environment.

Learners explore the ecological foundation of India's and ways to save the forests, water and the India tiger. After a lecture on identifying a healthy forest and the importance of the animals, students participate in activities to...
