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. 

Learners research a variety of local and world ecosystems. Students will create a collage to represent the biotic and abiotic factors and interactions important to their given ecosystem.Learners will understand that an ecosystem is...

Students create and conduct experiments on a "classroom river habitat." They manipulate the biotic and abiotic factors so that they are able to compare an artificially prepared river model to a naturally occurring lotic ecosystem.

High schoolers assemble a classroom river model as an example of a lotic system. They control and measure biotic and abiotic information for the in-class system and compare data with a lotic system in a natural environment.

In collaborative groups, young ecologists measure the temperature, pH, and dissolved oxygen for three different freshwater samples. They examine each sample with a microscope and record observations on the microorganisms in the pond...

Fourth graders  search the shore and find objects on the beaches of Hawaii.  In this exploring Hawaii's beaches lesson, 4th graders play "I Spy" with objected collected at the beach.  Students compare biotic and abiotic...

Students use a light microscope to observe the organisms living in a sample of ocean or fresh water. Students create a drawing of the organisms that they observe. Students then discuss the different body plans of the organisms and the...

Students investigate the chemistry of water and how its molecular structure supports life through its biochemcial, physical, and environmental roles. They investigate the quality of water as it interacts with the environment. Students...
