Water Density Boundaries
Students create observable layers in water that represent a separation based upon density differences. They model density boundaries using differences in temperature and salinity. They, in groups, perform a meaningful experiment...
Curated OER
Aquatic Communities
Students watch a video about aquatic communities. They conduct an experiment that shows how movement of rivers change the landscape. They compare fresh and salt water communities and its wildlife.
Curated OER
Snow vs. Water
Students fill three cups with snow. They record the height of snow in each cup, and allow the snow to melt. Students measure the height of the water in each glass or cup, and record their results on the worksheet. They answer questions...
Curated OER
The Floating Golf Ball
Fourth graders discuss density. In this floating golf ball lesson students complete a lab activity on density while working in groups.
Curated OER
Water Density and Stability Lab
Students observe how different water densities and salinity control the depth at which different water masses occur. Submarines are used as a case study. This is a well-designed with an excellent worksheet.
Curated OER
Sink or Float?
Students predict and explore to discover which objects sink or float in fresh and salt water, predict how salt affect objects, write predictions on T chart, discuss difference between man-made and natural waters, and graph results.
Curated OER
Finding the Salt Front
Students discuss definitions of estuary, salinity, and the salt front. They listen as the teacher explains the Hudson River Miles and ways the upriver and downriver sections relate to the north and south. Students graph the salt front...
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
Salmon Life Cycle
In this life cycle worksheet, students fill in the blanks with words about the life cycle of a salmon. Students complete 20 words about the life cycle.
Curated OER
The Romans: Public Health and Water
In this Ancient Rome worksheet, students read about the public health system of Ancient Rome: aqueducts, public baths and sewers.
Curated OER
Exploring Marine Objects
Students identify the sources of water on Earth. In this life science lesson, students list the different plants and animals that live in the ocean. They explore marine objects in the lab and draw them.
Curated OER
Rivers for the Common Good
Students explore what effects improper waste disposal and water pollution have on the water cycle. They explore how philanthropic acts can help protect the water cycle and keep our water and planet clean.
Curated OER
Does a change in pH affect the growth and survival rate of aquatic plants?
Students determine if changes in pH affect the growth and survival rates of aquatic plants. They evaluate the optimal pH levels for the growth of aquatic plants.
Curated OER
Drop in the Bucket
Students study the sources for the water they use. They determine their town's major water supply and how many gallons per day does the population use.
Curated OER
Salmon Run
High schoolers examine the life cycle of the Pacific salmon and the impact of humans on salmon migration. They watch a Powerpoint presentation, trace migration routes on satellite imagery, and complete mock calculations of salmon energy...
Curated OER
Water, Water Everywhere
Students estimate the amount of water that can be found in its various forms including oceans, lakes, glaciers, rivers, etc. They view a demonstration about water distribution and discuss flash flooding safety precautions.
Curated OER
Learning Lesson: Salt 'n Lighter
Young scholars participate in a demonstration showing that as salinity increases density increases as well. They also examine the different densities of air. They discuss the amount of water displaced by large ships.
Curated OER
Sink or Float Experiment
Learners participate in an experiment to determine which objects float or sink. They use different amounts of salt for the objects and discover as the salt content increases, objects will float. They record their predictions and what...
Curated OER
Using A Winogradsky Column to Analyze Microbial Communities
Students use easily obtained materials to study ecological succession in a microbiological community. They collect water samples from outdoor sources in plastic bottles to observe and record changes.
Curated OER
Relating Number of Insect Species to Water Quality
Students are asked to respond to questions such as:" Have there been surveys of the area to inventory the species?" (For example, for a wetland area, do they know what amphibians live there and how abundant they are?) Are there any...
