# 12 Using Bottled Water as a Problem Solving Exercise in Chemical Identification
Students work in groups of two or three, groups are given four unidentified bottled waters in unmarked containers and the chemical characteristics taken from the label on the bottled waters. They devise and carry out a plan to match the...

Water Quality Survey: Monitoring the Sustainability of Pigeon Creek
Students research the History of Pigeon Creek (or any watershed in your area). For this environmental science lesson, students conduct field tests such as pH and nitrates. They collect data and compare what they collected with other groups.

The Surprise of the Blue Water
Learners become aware of factors that effect drinking water quality and how this could effect the health of their school environment. Students compose a business letter reporting their school water quality results to an appropriate...
Curated OER
Great Lakes Ecology
Young scholars 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...

What's in the Water?
Young scholars 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...
Curated OER
Controlling Nonpoint Source Pollution
Students examine factors affecting water quality. They test water in a local body of water to determine its quality. They collect data and continue monitoring the water monthly. They assess water quality in the home and on the farm.
Curated OER
Ecosystem Damage from Household Cleaners
Third graders assess the damage done to various ecosystems by cleaning products and discover how scientists test water quality. Using stream water and common household cleaning agents, they work in groups to test for pH levels. Once...

Scientific Data: It's Not as Pretty as It Looks!
The difference between accuracy and precision is fundamental for high school science learners. Using test kits for nitrate concentration in water, they compare readings with each other. They consider the accuracy, precision, and bias of...

The Effects of Water Quality on the Growth Rate of Freshwater Mussels
Students participate in a field and laboratory study to determine if local freshwater mussels are environmentally stressed.
Curated OER
Devising a Set of Experiments to Test Water for Dissolved Substances
High schoolers work together to test water samples for pollutants. They design data tables to collect and record their observations. They complete discussion questions to end the lesson.
Curated OER
Technology as a Tool of Science
Students monitor streams, take stream surveys, collect chemical and macro-invertebrate and stream discharge data. Using a digital camera, students observe the percentage of various types of vegetation on the flood plan, riparian area and...
Curated OER
Go Jump In The Lake!
Middle schoolers experiment with local lake water to determine the health of the lake waters. They explore the human impact on the lake water, hypothesize and share inferences in a scientific report.

Nutrients In Chesapeake Bay
Students perform pH and turbidity test to determine water quality. In this environmental science instructional activity, students analyze NASA database on chlorophyll-a in the bay. They explain how a small river area affects Chesapeake Bay.

Marine & Aquatic Habitats -- Journey of a Drop of Water Through a Watershed
Pupils discuss pollution and the steps in the hydrologic cycle. They follow a drop of water through a watershed simulation. They discover the components of a water cleaning system as well.
Curated OER
Outdoor Survivors
Fifth graders complete a survey to decide what are most popular plants among the class. They test the water quality in a nearby pond. Studnts test the quality of soil samples taken from their homes. Different plants are moistened with...
Curated OER
Acid Rain Research
Students collect samples of rainfall, cloud condensation, and water that trickles through the soil. These samples are tested for pH, conductivity, and the presence of sulfates, nitrates, calcium, and magnesium.

It's not as pretty as it looks!
Tenth graders investigate that measurement is often an inact science. They explore ways utilize available information to form hypotheses. Students investigate how to test hypotheses using the HACH test kits.
Curated OER
Ranking Salinity
Students explain the uses of titration in chemistry and in industry. In this chemistry lesson, students determine the concentration of an unknown solution using titration. They calculate the percent of salt in saline solutions.
