Curated OER
Great Salt Lake
Fourth graders make an ecosystem that brine shrimp can live in and take data as to what level of salinity the water is, how cold it is, and other data that students may think is important. They also hypothesize and predict the outcomes...
Curated OER
Ocean Layers
Students investigate how temperature and salinity causes ocean layering. In this ecology lesson, students observe and sketch their experimental result. They report their findings in class.
Curated OER
Sink or Float?
Students analyze the relationship between density, buoyancy, and salinity. In this chemical properties lesson, students read a background activity for the lesson and experiments to the topics. Students discuss the questions and complete...

Urban Ecosystems 2: Why are There Cities? A Historical Perspective
Second in a series of five lessons, this lesson encourages preteens to consider cities as urban ecosystems. First, they keep a food diary for a few days. They visit the Natrional Agricultural Statistics Service website for current data...
Curated OER
Understanding Salinity
Students discuss why the ocean is salty. They discuss what salinity is. Students are told that is they want to know how much salt is in a body or water, they would use a special scientific tool. They complete an Estuarine Layers science...
Curated OER
Salinity Of Soil
Fourth graders investigate the contents of various types of soil to determine the differences in salinity levels. They conduct an experiment of observing the plants in the different soils. Students then determine survival rates by...
Curated OER
Teacher's Guide For: Water Temperature and Salinity Experiment
Learners experiment with water density, temperature and salinity. For this water lesson, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.
Curated OER
Where Are The Dinosaurs?
Students examine the concept of extinction in relationship to the dinosaurs. In this elementary science lesson students become familiar with dinosaurs and that they are extinct. Students differentiate between different types of dinosaurs.
Curated OER
Weather, Sea Level Rise and Climate Change Course
Students explain the impact of glacial melting to global climate change. In this environmental science lesson, students design an experiment to investigate the effect of salinity change to melting glaciers. They share their results to...
Curated OER
Fish Farm: an open ended, student centered laboratory activity
Young scholars are contacted by a fictitious company which raises tropical fish to do basic research for them so that they might keep their production costs down. They need to know the optimum salinity in which to hatch the brine shrimp...
Curated OER
Estuarine Currents
Students experiment observing a demonstration on models of density-driven currents which are typically found in an estuarine system of water flow. They compare/contrast water temperature and salinity to the formations of estuarine currents.
Curated OER
Soil pH & Plants
High schoolers investigate the pH of the soil in which different plants grow. They design and carry out an experiment to determine the factors that affect the growth of a population of plants, identifying and controlling major variables...
Curated OER
Water Layering and Circulation
Young scholars examine relationships and interactions between different types of water. They experiment with colored water of different temperature and salinity and discuss how the results relate to real ocean currents.
Curated OER
The Future of Arctic Sea Ice
Learners research about the importance of sea ice to world climate and sea organisms. In this earth science lesson, students create a model of present and future Arctic sea ice communities. They discuss how ice melting affects...
Curated OER
Water Will, Water Way
Young scholars test tap water for hardness and mineral content. For this environmental science lesson, students identify the different stages of the water cycle. They classify plant and animals according to the rules of taxonomy.
Curated OER
Saltwater Science
Students conduct an experiment that shows them how salt water allows things to float. In this salt water lesson plan, students mix ingredients together to create salt water and observe how it makes the oceans dense. They then interpret...
Curated OER
Active Transport in Malpighian Tubules
Students examine the energy dependence of active transport as well as te properties of specificity, competition, saturation, and inhibition. They anesthetize an insect and inject saline into the abdomen.
Curated OER
Blood Tonic
Young scholars investigate the process of osmosis using fresh potato cuttings in saline solution. In this biology lesson, students explain the difference between hypertonic, hypotonic, and isotonic solutions. They collect data from the...
Curated OER
One World Ocean
Students compare and contrast the properties of salt water in the oceans/seas and freshwater elsewhere on the planet. They also analyze mixing caused by currents in the ocean, including the effects of warm and cold water as well as with...
Curated OER
Water Quality Monitoring
Pupils 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
Water Density Boundaries
Young scholars 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...
Alabama Learning Exchange
The Composition of Seawater
Students explore the concept of finding the composition of seawater. For this finding the composition of seawater instructional activity, students make a saturated salt water solution. Students discuss why there is variation in ocean...
Curated OER
Environmental Differences
Students observe and conduct an experiment to see whether differences in salinity (the environment) have an affect on the hatching rate and survival of brine shrimp.
Curated OER
Learning Lesson: That Sinking Feeling
Students discover the origin of the Great Ocean Conveyor. They participate in a demonstration showing how salinity and temperature affect water density. They also examine the new sea ice that forms every winter.
