Living Organisms as Indicators of Pollutants in Fresh Water Ecosystems
Students observe the effects of pollution on living organisms. In this pollution lesson plan, students observe fresh water Hydra and look at their structures and movement. They place samples of pond and lake water on the Hydra and...

Microorganisms in Pond Water
That is living in the water? Groups of two to three view pond water with microscopes in order to find microorganisms. They draw pictures of the ones they find in their slides. The groups compare their drawings to pictures of common pond...

Effects of Water Pollution on Aquatic Organisms
Young scholars investigate water pollution. They develop an understanding of the behavior of organisms, of the structure and properties of matter, and of natural and human induced hazards by conducting lab tests. They present their data...
Curated OER
Aquatic Ecosystem Exploration
Students visit a local stream, pond, creek, or river and collect macroinvertebrates. They sort macroinvertebrates and identify each species using a dichotomous key. Students decide on trophic levels and construct a possible food web for...
Curated OER
Lentic Ecosystem or Lotic Ecosystem
Students explore the differences between lentic and lotic ecosystems. In this ecology instructional activity students study the water systems in Pennsylvania.
Curated OER
Dibble Pond Ecosystem
Students collect specimen and analyze it. In this biology lesson plan, students analyze and evaluate the diversity found in specific environment. They use the correct terminology as they do their write up for the experiment.

Does the Introduction of Pesticides and Fertilizers Alter an Aquatic Ecosystem?
Students conduct an experiment using a small sample from a local water source. They introduce fertilizers and pesticides, separately, and carefully examine the results in their simulated aquatic ecosystem.
Curated OER
The Effect of Medications on Daphnia
Students explore how human beings affect the world's ecosystem by examining the affects of medication on daphnia, a small freshwater organism very sensitive to pollution. Students use a computer model to repeat the experiment and analyze...

Determination of Overall Water Quality Using a Quantitative Macroinvertebrate Survey
Students examine water samples from a local stream. They identify various types of macroinvertebrates found in that water ecosystem and perform a quantitative macroinvertebrate survey to determine the stream's water quality.
