Curated OER
Water Quality and Dissolved Oxygen
Learners 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
Dissolved Oxygen Activity
Students explore why dissolved oxygen must be present for aquatic life to survive. They explain what dissolved means. Students discuss what dissolved oxygen is. They watch as the teacher lights two candles and place a jar over one of...
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.

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...
Curated OER
Salmon Scavenger Hunt
Students go on a salmon scavenger hunt to find out about threats to salmon populations. They gather information about some of the reasons wild salmon have gone from such incredible abundance to relative scarcity, and about some of the...
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...
NOAA
History's Thermometers
How is sea coral like a thermometer? Part three of a six-part series from NOAA describes how oceanographers can use coral growth to estimate water temperature over time. Life science pupils manipulate data to determine the age of corals...
Curated OER
Water Quality and Nitrates & Phosphates
Students examine the effects of nitrates and phosphates on the dissolved oxygen levels in different water sources. For this series of 3 lessons, they consider the reasons for nitrate and phosphate level increases and their effects on...

Making Connections with Water Quality
What's in your water? And, why is water quality so important? Enhance your class's level of water appreciation through a lesson that demonstrates the necessity of water quality. Environmental enthusiasts explore the EPA's Clean Water...
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
Save Your Breath
Students discuss metabolism. In this metabolism lesson, students evaluate evidence form a research report and discuss the basis for hypothetical metabolic adaptations to low-oxygen environments in the anchialine caves.
Curated OER
Solutions and Suspensions
Students explore matter by conducting an in class demonstration. In this liquid mixture activity, students identify the difference between a solution in which a solid dissolves into liquid, and a suspension where the solid doesn't...

Let's Learn About Stewardship and River Basins
What does it mean to be a good steward? Middle school environmentalists learn to care for their state's waterways through research, a guest speaker, and poster activity. Groups must locate and learn more about a river basin and the human...
Curated OER
Nature and Fitness Trail
Young scholars plan stations for a nature and fitness trail and construct an accompanying e-Book for extended descriptions at each station. Data on the human impact on the environment is gathered in this lesson.
Curated OER
Establishing a Baseline Ecology of a Creek Ecosystem
Students investigate the physical, chemical and biological parameters necessary to establish an ecological baseline. Establishing an ecological baseline not only shows the ecological characteristics of a creek but makes the possible...
Curated OER
What Are We?
Students list and describe three types of surface water pollutants. They observe the effects of various water pollutants on algae growth. Three causes of each surface water pollutant is listed.
Curated OER
Tracking Narwhals in Greenland The Ocean Unicorn
Learners study the ecology, habitats, geographic range and feeding habits of narwhals. They determine at least three reasons for the decline in the narwhal populations and complete the accompanying worksheets.
Curated OER
Frozen Out
Students investigate how climate changes affect top predators in Arctic marine ecosystems. Students complete a worksheet and write a report based on their responses to a scientific paper.
Curated OER
Leaf - It's What's for Dinner
Students discover correlations in food preferences of invertebrates, and assess stream health through use of kicknets, invertebrate keys, CBL systems and probes.
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.
Curated OER
"Pennsylvania Watersheds, Many Ways to the Sea"
Students trace a molecule of water through the water cycle including each of its three loops. They describe why evapotranspiration demands the largest portion of total precipitation falling on a forested watershed.
Curated OER
Water Chemistry
Students engage in a lesson that is concerned with the concept of water chemistry. They conduct research using a variety of resources. Students also consider an experiment to observe how water has the abiility to exist as three different...
