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
Analyze the Results
Pupils conduct water tests and sample macroinvertebrates from a nearby source to make a general determination about the overall quality of water. They use worksheets and analyze data as part of a larger unit.
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
All Messed Up
Pupils begin the experiment by mapping and calculating their school parking lot. They calculate the volume of water falling on the lot and map the route the water runoff takes. They discuss the roles that humans play in affecting water...
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
Turbidy and Water
Students use observation skills in assessing the water quality of water samples in this activity and learn that the tastes and preferences of others can be different.
Curated OER
Pollution Solutions
Learners visit a local park to test the quality of the aquatic environments. They search for sources of pollution and examples of pollution control. Based on their obeservations and experiments, they rate their local environment.
Curated OER
Biomanipulation
Young scholars explore the effects of aquatic trophic relationships on water transparency. They observe and explain the effects of reducing nutrient inputs on agal density on water transparency.
Curated OER
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
Stream Chemistry Monitoring
Learners 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
Eutrophication Experiments
Observe two different water samples and write down observations. Write a paragraph which predicts the relative amounts of nutrients, nitrates, and phosphates in the water samples. Compare water samples under a microscope.
Curated OER
Health of Aquatic Life a Real Problem
Learners explore the health of aquatic life in this science instructional activity They measure and track the oxygen level in the water to determine the health of the aquatic life. They collect this data using the TI explorer to graph...
Curated OER
Nutrients In Chesapeake Bay
Students perform pH and turbidity test to determine water quality. In this environmental science lesson plan, students analyze NASA database on chlorophyll-a in the bay. They explain how a small river area affects Chesapeake Bay.
Curated OER
Water Quality and Temperature
Students are led through three activities to explore the effect of temperature fluctuations on the growth and survival of aquatic plants, clams, and shrimp eggs.
Curated OER
Science Excursion: Cover Mapping Land
Young scholars study remotely sensed images and topographic maps to classify land cover types in their watershed area. They take samples in the watershed area to interpret the images.
Curated OER
Playing in mud puddles
Students examine the effects of rainfall on different surfaces and discuss water pollution. They review the water cycle and the uses of water in daily lifestyles. Students discuss the effects of soil run off in streams and rivers.
Curated OER
Getting the "Yuck" Out
Students examine various types of household materials for their usefulness as filters. They work together in teams to design a filtration system that produces the cleanest water in the shortest time.
Curated OER
Settling Rates of Different Size Particles
High schoolers discover how and why the settling rate of particles differs with the size of the particles. Using different soil samples, they calculate the amount of time it takes for a sample to settle in water for up to forty minutes....
Curated OER
Gonna Take a Sedimentary Journey
Students collect water samples from a local source, test it, filter it and identify the materials suspended in it. Students disucss the possible sources of sediment in their watershed.
Curated OER
Sediment Tubes
Students observe how different density soils and rocks behave in wind and in water. They make predictions and careful observations as they explore sediment transport and sediment rates in streams and rivers.
Curated OER
Density Currents
Students study how fluids of differing densities interact with one another, how densities of fluids can be changed, and how density currents transport and deposit tremendous amounts of sediment in lakes and in the ocean.
NOAA
Currents
A deep ocean current circles the globe at a force that is greater than 16 times all the world's rivers combined. Groups analyze the effects of submarine topography on deep ocean current speed. They then determine how this speed affects...

A Quest for Anomalies
Sometimes scientists learn more from unexpected findings than from routine analysis! Junior oceanographers dive deep to explore hydrothermal vent communities in the fourth lesson in a series of five. Scholars examine data and look for...
Curated OER
Dissolved Oxygen and Photosynthesis: 1
High schoolers are taught that plants produce oxygen underwater, and they design an experiment that test this question. They discuss whether plants give off oxygen, and how to measure this. Students measure the increase in dissolved...
