Dissolved Oxygen and Temperature
Young scholars are shown how temperature affects dissolved oxygen and they create a graph showing this relationship. They think about the adaptations of animals to live in different water temperatures. Students test four different water...
Curated OER
Dissolved Oxygen Introduction
Students are shown how dissolved oxygen enters the water. They are taught the difference between a water sample that has been exposed to the air and one that has not. Students brainstorm what organisms need to survive. They use dissolved...
Curated OER
Dissolved Oxygen and Respiration
Students are presented with the question, "Do plants that grow underwater use oxygen?" They create an experiment to test the presence of dissolved oxygen in the water using provided materials. Student experiments include a control jar as...
Curated OER
What If There's No Light?
students discuss the importance of light and the consequences of living without it. Using a plant as a demonstration, students predict and observe what happens to a plant when it does not receive enough light. In groups, they experiment...
Curated OER
Reading the River
In collaborative groups, young ecologists measure the temperature, pH, and dissolved oxygen for three different freshwater samples. They examine each sample with a microscope and record observations on the microorganisms in the pond...
Curated OER
Teaching about the Effect of pH on Aquatic Organisms
Students perform experiments to determine the PH, acidity, and buffering qualities of a lake that make them sensitive to acid deposition.
Curated OER
Diurnal Cycling Experiments
Students carry out an experiment to monitor diurnal fluctuations in dissolved oxygen, carbon dioxide, pH, and water temperature. They determine the CO2 and pH of the samples (and optionally, dissolved oxygen). Students complete their...
Alabama Learning Exchange
Is My Water Safe?
Learners discuss what makes their drinking water safe and unsafe. They locate and visit a local tributary and test the water's pH, hardness, dissolved oxygen, and total alkalinity. They compose a summary paragraph about the tests and...
Curated OER
How about a Little Give and Take?
Students design a closed system to test the relationships between plants and animals. They monitor abiotic fluctuations within this living system by using a chemical test kit. They observe how living organisms respond to fluctuations in...
Curated OER
Freshwater Fish Water Quality
Sixth graders work together to complete an experiment about the quality of freshwater. In groups, they collect fresh water samples from a variety of sources and test the pH levels. After completing a KWL chart, they test the amout of...
Curated OER
Testing the Waters
Eleventh graders examine a local body of water. In this science lesson, 11th graders collect water samples to test. Students analyze the data and make conclusions. Students create tables and graphs of the data.
Curated OER
Water Quality in the Greenhills Stream
Seventh graders conduct year long study of water quality over different seasons using variety of probes, including D.O., pH, conductivity and temperature, that are attached to portable technology. Students select three data points in...
Curated OER
Great Lakes Ecology
Students are able to use a secchi disk to measure the turbidity of water by determining the depth at which the sechi disk is no longer visible and using the data in a formula to quantify the results. They are able to use Vernier probes...
Curated OER
What's in the Water?
Students make a water sampler and use proper techniques to collect water.They write a essay explaining the inter-relationship of factors such as temperature, pH, dissolved oxygen, nitrates, and phosphates in a lake that might cause a...
Curated OER
Aquatic Field Data
Learners use laptops and sensors to measure water quality and graph their results. In this aquatics instructional activity students post their results to a website or email.
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
Shoreline Seining and Sampling
Students investigate ecological systems and the cause and effect relationship between humans and the environment by using the prey items of Ospreys.
Curated OER
To Drink or not to Drink
Seventh graders discuss water quality, water availability and water resources and how water is used in the world around them. They view a video on water quality then test for pH, temperature and dissolved oxygen to indicate water quality.
Curated OER
Creek Monitoring
Sixth graders conduct a variety of assessments at a local stream to determine if it is a suitable habitat for salmon. They measure temperature, tubidity, dissolved oxygen, pH levels, bacteria and nutrients. In this unit, 6th graders work...
Curated OER
Stream Chemistry Monitoring
Students become familiar with real-world gathering of chemical data. The experience how the science is done: the nature of analysis, data collection, interpretation, and presentation. They study a nearby body of water for their experiment.
Curated OER
What Is In The Water?
Learners investigate the biotic and abiotic factors that are found in an aquatic ecosystem. The emphasis is upon the investigation of present an projections of future water quality. Then students visit a local body of water to gather...
Curated OER
Science Investigation Using Water Quality
Eighth graders conduct an experiment that analyzes the physical and chemical characteristics of various water samples. They discuss the procedures and safety concerns for the water test, and test their water samples to determine if they...
Curated OER
Water Quality Survey: Monitoring the Sustainability of Pigeon Creek
Students research the History of Pigeon Creek (or any watershed in your area). In this environmental science instructional activity, students conduct field tests such as pH and nitrates. They collect data and compare what they collected...
Curated OER
Water Quality Testing
Student explore factors affecting ecosystems. They test local water samples for pH level. After creating a methodology for data collection, they collect data, compare results, and draw conclusions based upon results.
