Curated OER
Wetland/Estuary Structure and Functions
Learners plant wetland plants in aquatic soil and regular soil. They test the effect fertilizers have on each and record the chemicals found in run-off water collected from each soil sample.

Nitrogen in Pollutants
Responsible farming is important for maintaining natural resources. Eager scientists complete a WebQuest to explore what happens to nitrogen when it enters the soil. They learn about the chemical makeup of nitrogen-based molecules and...
Curated OER
Necessary Nitrogen
Students view a video that presents the biogeochemical cycle of nitrogen. They compare types of soils and consider how different fertilizers affect soil composition.
Curated OER
Outdoor Survivors
Fifth graders complete a survey to decide what are most popular plants among the class. They test the water quality in a nearby pond. Studnts test the quality of soil samples taken from their homes. Different plants are moistened with...
Curated OER
Soil Microbiology- Nitrogen cycle
Students take a virtual trip to a Catfish Aquaculture Pond and analyze soil bacteria to determine how many nitrogen cycle bacteria are present. They graph the number of colonies present and use data to determine ammonium levels in the soil.

What's in This Water?
Pupils investigate the biological and chemical characteristics of water to determine where purple loosestrife occurs. They create data sheets to record water quality tests in several locations and work in groups to conduct the water...
Curated OER
Bog Science
Students study bogs. They tour, collect physical, chemical, and biological data and analyze a pristine bog community. Using the data, they draw a map and a cross section of the bog.
Curated OER
Testing Your Water
Students perform several water quality tests on groundwater from their area. They use test strips to determine the pH, hardness, alkalinity, nitrates, iron and chloride levels.
Curated OER
Acid Rain Research
High schoolers collect samples of rainfall, cloud condensation, and water that trickles through the soil. These samples are tested for pH, conductivity, and the presence of sulfates, nitrates, calcium, and magnesium.
Curated OER
Technology as a Tool of Science
Students monitor streams, take stream surveys, collect chemical and macro-invertebrate and stream discharge data. Using a digital camera, students observe the percentage of various types of vegetation on the flood plan, riparian area and...

The Biogeochemical Cycles
The majority of this presentation is a collection of diagrams and graphs that back your lecture on biogeochemical cycles. The last few slides define ecosystems and the Gaia hypothesis. You may find these slides valuable, but will...
