Algae Blooms
Your microbiologists explore a changing algae population and build an exponential function modeling algae concentration from the description given of the relationship between concentrations in cells/ml and days of rapid growth.

What are Some Substances That Will Cause Algae To Grow?
Students discover algae. In this science lesson plan, students examine what green algae is and where it grows. Students determine the effects of oil, detergent, copper crystals sulfate and lawn fertilizer have on the growth of algae.

Measuring Exponential Growth
Students reinforce math skills while learning about best practices
for protection of water quality in the management of animal feeding
operations. They make a table to show results of their calculations and compare and justify findings...

Testing Growth of Algae
Students participate in an experiment in which they test the growing rate of algae. They test the algae in different elements recording their observations. They share their results with the class and discuss.
Curated OER
What Are We?
Students list and describe three types of surface water pollutants. They observe the effects of various water pollutants on algae growth. Three causes of each surface water pollutant is listed.
Curated OER
Biomanipulation
Students explore the effects of aquatic trophic relationships on water transparency. They observe and explain the effects of reducing nutrient inputs on agal density on water transparency.
Curated OER
Mud in the Water
Sixth graders investigate erosion. In this erosion lesson, 6th graders explore how farming changes the environment. Students construct an erosion model and research ways to protect the soil from excess mud generated by farming.
Curated OER
Fertilizer Frenzy
Young scholars design and conduct an experiment testing the effect of fertilizers/soaps on algal growth. They estimate and predict, identify the variables, formulate a hypothesis, and record and analyze the data, presenting their...
Curated OER
Observing Brine Shrimp
Students observe brine shrimp eggs, create an appropriate environment for their survival, and observe their growth.
Curated OER
Pond-water Populations
Pupils design and conduct and experiment on algae, for a two week period, to answer the question "In your investigation, how does changing one factor affect the growth of organisms?"
Curated OER
What Are We?
Students describe different types of water pollutants. They complete experiments in which they observe the affects of water pollution on algae. They also brainstorm and list three causes of each water pollutant.
Curated OER
Fertilizer Frenzy
Ninth graders design and conduct an experiment. They evaluate other's experiments. Students describe relationships between biological systems and the environmental contaminants. They work as a team to solve a problem.
Curated OER
Should Populations in an Ecosystem be Restricted?
Fourth graders experiment to determine how overpopulation effects ecosystems specifically plants. In this ecosystem lesson, 4th graders conduct an ecosystems experiment after listening to Claire Daniel's, Ecosystems. They watch a video,...
Curated OER
Pollution Solutions
Students visit a local park to test the quality of the aquatic environments. They search for sources of pollution and examples of pollution control. Based on their obeservations and experiments, they rate their local environment.
Curated OER
Nutrients In Chesapeake Bay
Students perform pH and turbidity test to determine water quality. In this environmental science lesson plan, students analyze NASA database on chlorophyll-a in the bay. They explain how a small river area affects Chesapeake Bay.
Curated OER
Where's My Bot?
Students estimate geographic position based on speed and air travel. In GPS lesson students use GPS to estimate the set and drift of currents.
Curated OER
Water Quality Monitoring
Students comprehend the four parameters of water quality. They perform tests for salinity, dissolved oxygen, pH and clarity or turbidity. Students comprehend why scientists and environmental managers monitor water uality and aquatic...
