Curated OER
Down By the River
Students examine how watersheds work and determine the difference between point and nonpoint source pollution. They research management practices to reduce pollution and investigate how everyone can participate in reducing water pollution.
Curated OER
Water Quality and Dissolved Oxygen
Students investigate the relationship between dissolved oxygen and organic materials and aquatic organisms. This is a 3-lesson series in which students explore dissolved oxygen and then design an experiment testing the effects of changes.
Curated OER
The Water Detectives
Students collect water samples from designated sampling stations, and discuss water pollution. They analyze the water samples, record the data on a spreadsheet, and present the environmental water quality data to the class.
Curated OER
Clean Water vs. Dirty Water
Students study the importance of clean water to the survival of organisms and what activiities and material pollute water. They measure the temperature of water samples and create a class graph.
Curated OER
BIOASSESSMENT OF STREAMS
Young scholars work as a team to gather organisms from a stream to evaluate if the water quality is excellent, good, or fair to poor.

Hands On Biodiversity: Networking Students and Their Biomes
Students telecommunicate and use the US Mail to network students from five biomes in the United States in order to monitor water quality in each area. They have e-mail pals and exchange materials representative of themselves and their...
Curated OER
The Dirt on Soil
Students classify different soil types. For this earth science lesson, students explain the factors that affect groundwater quality. They design and build a water treatment plant.
Curated OER
World-Water Hero
Learners explore why clean water is essential. For this environmental lesson, students identify the "powers" we need to improve the quality of water. Learners share their descriptions of world-water superheroes.
Curated OER
Assessing Water Quality in a Local Creek by Sampling Aquatic Macroinvertabrets
Students experiment collecting macroinvertebrates from a stream and identify the specimens collected and then log in the information into a data table. From the data, they make qualitative and quantitative interpretations of water quality.
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...
Curated OER
The Importance of Water
Students explore the importance of water. They discuss why water is important and students design an experiment that evaluates the water quality and methods of improving water quality. Students perform testing and report their findings.
Curated OER
Underwater Picture of the Hudson River Estuary
Pupils identify important aspects of water quality such as slainity and turbidity. They test two of the water quality parameters and determine the quality of the water. In addition, they construct two sets of graphs based on data...
Curated OER
Fish Kills!
Students investigate a fish kill occurrence, the Lake Iluka simulation. They examine what would happen if a fish kill happened today in their watershed area? what type of problems it might cause? They also discuss in groups any specific...
Curated OER
Water Pollution Graphing Activity
Students describe and identify the link between land use activities within a watershed and water quality. They evaluate the quality of a "water sample" ( a bag of skittles), graph their results, and form a hypothesis about the land use...
Curated OER
Water Quality Sampling
Learners explore the water qualities in Texas. They evaluate the water quality of six different samples by observing and smelling them. They present a list of the cups that contained good water quality based on their observations. They...
Curated OER
Water Quality
Learners are presented with a hypothetical situation to investigate the water quality of the James River. They are given data to analyze and put into the graphic organizer that is included to help solve the problem. The lesson includes...
Curated OER
Investigating Earth's Materials
First graders compare and contrast water from different sources. After collecting water from various sources, 1st graders create a list of observable properties of the water. Students then pour the water into a filter and observe the...
Curated OER
Water Pollution
First graders investigate what causes water pollution and conduct a water pollution experiment. They listen to the story "What Polluted the Potomac?," and during the story pour small containers of dirty water into a large container at...
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
How Clean is that Water?
Middle schoolers conduct a water quality experiment on a local stream using benthic organisms as a water quality indicator. Based on the results from the experiment, students determine how engineers use this background information to...
Curated OER
Testing the Waters
Students study the quality of water by running chemical tests on the water. First, they measure pH, temperature, phospates, and nitrates in tap (drinking) water and an outdoor water sample. Then they post and evaluate the results of...
Curated OER
Water Quality
Students examine the YSI and the water properties that it measures. They identify the different properties of water pH, DO, temperature, turbidity, and salinity and determine why it is important for them to test these parameters.
Curated OER
Human Impact on Water Quality
Learners identify at least three common repercussions of developing water front property on water quality. They describe three sources of water pollution. They research the organism striped bass and observe it if striped bass is available.
Curated OER
The Water Dilemma
Students read about and discuss the importance of easily available, clean drinking water. They participate in a role play scenario in which only one drinking fountain in the school has potable water.
