Students identify the abiotic factors that influence a river or stream and the organisms that live in it. They measure several abiotic and biotic parameters to gauge water quality. Students examine the biotic environment by identifying...

Students identify biotic and abiotic factors. In this environmental study lesson, students conduct a series of experiments to collect and record data and draw conclusions based on the results. 

Students carry out an outdoor land study in which they identify organisms living in the soil, and any other animals living within the site. Groups also examine abiotic factors. They respond to a series of questions concerning their data...

Seventh graders examine proper journaling techniques, and record observations about at tree after listening to a read aloud of "Four Worlds: The Dine Story of Creation." They study the difference between living and non-living things, and...

Students share their prior knowledge of the elements of the environment. In groups, they are introduced to the concepts of biotic and abiotic factors in a specific environment. They discover their effects on organisms living in the...

Students identify individual organism, a species, and a population within the study community. They identify biotic factors at the site and attempt to characterize the site's species diversity.

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.

Students investigate the biotic and abiotic factors that are found in an aquatic ecosystem. The emphasis is upon the investigation of present an projections of future water quality. Then students visit a local body of water to gather...

The relationships within and between ecosystems can be explored. after examining an area for living and non-living things students complete the same examination in the forest ecosystem. Students identify abiotic and biotic elements in an...

Modeling is a powerful teaching tool. The final installment in a six-part series has pupils complete an activity to model a food web and discover the interconnected relationships in an ecosystem. They then read about changes in migratory...

Students learn how to count animal populations by the Mark and Recapture method. In this counting animal populations lesson plan, students begin by predicting amounts of different candies in a jar. Students then simulate using beans, two...

Students describe safe practice when doing field and lab investigations in a estuary or wetland. They create a model of an estuary and describe their value and function. They participate in field study in which they collect and analyze...

Students study plants and what they need to thrive and survive. They make plant extracts from chosen wetland plants and test their allelopathic effects on the germination rate, radicle growth, and hypocotyl growth of test seeds of other...

Students chemically test water, observe microscopic organisms in the classroom, and screen the sample for macroinvertebrates. They design a reporting sheet that list all the items to be tested and a space to record the results.

Students continue their examination of the existence of life on Earth. In groups, they determine the role of the water cycle and other biogeochemical cycles play in keeping balance on Earth. They participate in experiments to discover...

Students explore oceanography by participating in a flash card activity. In this ocean inhabitant activity, students define a list of ocean related vocabulary terms and answer ocean geography study questions. Students utilize organism...

Seventh graders design and conduct experiments to determine what environmental factors favor decomposition by soil microbes. They use chunks of carrot for the materials to be decomposed, and their experiments are carried out in plastic...

Students study the biotic and abiotic factors of an environment.  In this exploratory activity students examine the different trophic levels and how organisms are connected. 

Students study and analyze data collected on the relationship between the snowshoe hare and lynx in Canada over a 28 year period and create a graph. Students also write a response to a proposal to reduce the lynx population.

Students observe their local forest and document the change that occurs over the school year.  For this forestry lesson, students utilize a GPS to mark a certain area of the woods as their study area for the remainder of the year....

Students study the habitats found in their schoolyard. They apply firsthand, what they have learned in the classroom to something familiar to them. Students look at biotic, abiotic habitats. Small groups will present their findings to...

Students describe the roles of controlled, manipulated and responding variables in scientific research. They also identify biotic and abiotic interactions affecting the makeup of a plant community.

Is it really that big of a deal if the global climate undergoes a little change? Young environmentalists consider this very question as they discuss in small groups the impact of different climate change scenarios on their lives,...

Students participate in a prey-predator game. After reading background information, they discover the impact from the changes global warming presents to the polar bears and ringed seals. They role play the role of either the seal or...
