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...
Curated OER
Dissolved Oxygen in an Aquatic Ecosystem
Students explain why dissolved oxygen is important in aquatic ecosystems. They evaluate the optimal dissolved oxygen levels for living organisms.
Curated OER
Dibble Pond Ecosystem
Learners collect specimen and analyze it. In this biology lesson, students analyze and evaluate the diversity found in specific environment. They use the correct terminology as they do their write up for the experiment.
Curated OER
Eutrophication
Students observe the effects of eutrophication and determine why it is harmful to aquatic ecosystems. They create mason jar ecosystems to observe the growth of algae in pond water. In addition, they observe the effect of introducing...
Curated OER
Norman Suburban Activity
Students analyze the factors affecting organisms in the pond ecosystem. In this environmental science lesson, students perform an experiment to determine pH, nutrients and temperature of different pond sites. They present their result to...
Curated OER
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
Organic Materials in an Aquatic Ecosystem
Students evaluate the relationship between oxygen levels and the amount of organic matter in an aquatic ecosystem. They explain the relationship between oxygen levels, bacteria and the breakdown of organic matter using an indicator...
Curated OER
Daphnia and Algae: A Study of Pond Dynamics
Students observe interrelationships and interdependencies of organisms which may generate stable ecosystems. They also study that living organisms have the capacity to produce infinite sized populations, but environments and resources...
Curated OER
Discovering The Oasis
Students participate in a lesson that is concerned with the ecosystem of a local pond. The teacher makes arrangements for students to take a field trip. Time is spent in class for preparation and afterward for debriefing of lab...
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...
Curated OER
How Do Plants and Animals Change the Environment Around Them?
If you have elodea and snails in your classroom aquarium, or if you have access to a pond with these organisms, your young biologists can set up a controlled experiment to determine how certain ecosystems respond in light and dark...
Curated OER
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.
Curated OER
Does a change in pH affect the growth and survival rate of aquatic plants?
Students determine if changes in pH affect the growth and survival rates of aquatic plants. They evaluate the optimal pH levels for the growth of aquatic plants.
Curated OER
How Do Populations Grow?
Students examine how populations grow and how invasive species can affect the balance of ecosystems. They simulate the growth of lily pads, analyze and record the data, and simulate the results of an invasive species on an ecosystem.
Curated OER
Does the increased use of fertilizers effect biodiversity?
Students conduct a hands-on lab activity in which they analyze a sample of water from a local stream or pond. They introduce a fertilizer solution into the sample and analyze and describe their findings.
Curated OER
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
Sustaining Life Under the Ice
Students design and conduct experiments in order to identify the components of lake water environments that are affected by winter ice cover. They use the experiment results to propose effective human management of these ecosystems.
Curated OER
The Water Cycle
Pupils develop a better understanding of the need to conserve our renewable resources. In this water cycle lesson students take notes, complete a guide sheet and illustrate the water cycle.
