Salinity Lab
In this salinity worksheet, students simulate conditions of salt and fresh water mixing and observe the various densities of these solutions based on their salinity.
Curated OER
The Open Ocean, What is it and How Does it Change?
Students investigate the ocean environment. In this ocean instructional activity, students discover the physical properties of the ocean. Over two days, students work in small groups investigating ocean maps and creating water currents.
Curated OER
Water Layering and Circulation
Students 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
Ocean Life
Students explore the topics of ocean water salinity, ocean life zones, marine life classification, and ocean food chains. They observe demonstrations, conduct experiments, complete quizzes and handouts, and analyze key vocabulary.
Curated OER
Liquid Rainbow
Students develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.
Curated OER
Saltwater: Nifty Aqueous Colorful Layers
A classic investigation on the density of liquids is explained for you in this lesson plan. Te begin, you prepare water samples of different salinities and then add different food coloring to keep them separated and easily identified....
Curated OER
Count Marsili & the Mediterranean Current
Students integrate history and science while discovering how salinity affects the density of water. After a lecture/demo, students work in groups to complete a lab activity that demonstrates how salinity affects the density of water.
K12 Reader
Water Water Everywhere
The protection of our water supply is the subject of an article used in this cross-curricular reading comprehension worksheet. After studying the passage, readers use information from the text to respond to a series of comprehension...
Curated OER
Building A Solar Still
Students investigate the water cycle by viewing an online video. In this drinking water lesson, students create solar stills at their campus in order to purify water that is tainted. Students view a video on their computers...
Curated OER
Density Dynamics
Students set up working models demonstrating lake turnover and the formation of deep water masses in the oceans.
Curated OER
Where in the World Is All the Water?
Students investigate the distribution of the earth's water. They conduct a demonstration of water distribution, and create a pie graph to display the results.
Curated OER
Salinity
Learners define and discuss salinity, conduct classroom experiment to determine salinity of water sample by using hydrometer, record predictions, and demonstrate understanding of how salinity influences object's ability to float in water.
Curated OER
Sea Water Freeze
Students observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water
Polar Trec
Nature's Density Column
Nature provides density columns in the polar regions that provides food for many animals. Young scientists build their own density columns with water in order to answer analysis questions. Through a slideshow presentation, scholars...
Curated OER
Properties of Fresh and Sea Water
Students work with three stations to demonstrate the properties of water. They explore water's boiling point, freezing point, and its ability to store heat.
Curated OER
Monitoring Estuarine Water Quality
Young scholars analyze water quality data from real data. In this environmental science lesson, students examine how salinity and dissolved oxygen affect the living organisms in the estuary. They interpret graphs to support or disprove a...
Curated OER
What Lives in the Open Ocean and Where Do They Live?
Young scholars explore oceanography by participating in a flash card activity. In this ocean inhabitant instructional activity, students define a list of ocean related vocabulary terms and answer ocean geography study questions. Young...
Curated OER
Ocean Layers
Students investigate how temperature and salinity causes ocean layering. For this ecology lesson, students observe and sketch their experimental result. They report their findings in class.
Curated OER
Water Density
Students identify and analyze the concept of density using the formula, density equals mass divided by volume. They review the differences in salinity levels of the ocean and note that the changes in density are caused by wind and...
