Curated OER
Algae Experiments
Students describe the characteristics of algae. In this biology lesson, students perform a series of experiment to explore algae. They investigate the basic things algae need to survive.

Algae in the Aquarium
Tenth graders determine the cause of an algal bloom in a classroom aquarium. Students analyze the situation and present a solution to the problem in the given time frame after researching and conducting experiments. Solutions are...
Curated OER
Pea Soup Ponds
Students perform an experiment where they learn how water can be polluted by algal bloom. They grow algae with different concentrations of fertilizers or nutrients and analyze their results.

Eutrophication Lab
Young scholars examine the effects of detergents and fertilizers on aquatic life and describe algae. Students define the term eutrophication as the process by which a body of water, such as a pond, lake, stream, or river, has a sudden...
Curated OER
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
Phytoplankton and Ocean Color
Fifth graders identify function of phytoplankton in the biospere by conducting experiments and simulations and reading for information. They detect the presence of phytoplankton in bodies of water by examining ocean in satellite images...
Curated OER
Aquatic Foodweb
Students explore what a food web is. In this science lesson, students examine how nutrients and other pollutants enter a lake and play a food web game whereby students pretend they are either zooplankton, planktivore, piscivore, or...
Curated OER
Eutrophication Experiments
Observe two different water samples and write down observations. Write a paragraph which predicts the relative amounts of nutrients, nitrates, and phosphates in the water samples. Compare water samples under a microscope.
Curated OER
Mystery Spill
Young scholars investigate the cause of birds dying in Monterey Bay. In this scientific research lesson, students use various resources, scientific investigations, and vector analysis to solve an environmental mystery.
Curated OER
Secret Agents of Dissolved Oxygen
Students determine the changes in different types of water in a sealed container over time. They investigate how to measure dissolved oxygen, temperature, and carbon dioxide with calculator or computer probe-ware. Students determine the...
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.

BIOASSESSMENT OF STREAMS
Pupils work as a team to gather organisms from a stream to evaluate if the water quality is excellent, good, or fair to poor.
