Biocomplexity Lab Activity: Creating Salt Water
The lesson plan seeks to intorduce to students the properties of salt water and how to create salt water. Teacher gives backgound information about salt water to students. From that point, students dscuss what elements are in salt...
Curated OER
Hot, Cold, Fresh and Salty
Students observe the effects of layering water and what is more or less saline than normal. In this geoscience lesson students create saline solutions, layer them and observe how the water becomes different temperatures in different layers.
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...
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
Underwater Picture of the Hudson River Estuary
Students 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
Effects of the Southern Pacific Railroad Causeway
Fifth graders describe the appearance of a substance before and after a physical change. They re-create the Southern Pacific Railroad Causeway across the Great Salt Lake. They determine for themselves how the water is exchanged...

Outcomes Science 4
In this outcome science 4 worksheet, students apply scientific knowledge to answer and calculate a variety of questions. Students research the answer to several questions using the websites suggested.
NOAA
Ocean Layers II
Now that you know the ocean has layers, let's name them. The seventh installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program covers terminology associated with ocean layers, such as thermocline and...
NOAA
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
Disposable Diaper Comparison and Mystery Powder Identification
Students investigate which diaper is the most absorbent. In this chemistry lesson, students calculate how much water is absorbed by diapers. They identify an unknown powder based on physical and chemical properties.
Curated OER
The Effects of Storms
An excellent way to review a chapter or unit on storms, this worksheet features vocabulary review (gust, evacuation, storm surge, salinity), concept review (effects and details about hurricanes), skills/process review (normal high tide...

Desalination: Creating a Solar Still
To better understand how solar power can aid in creating desalinated drinking water, the class creates a model still. They will build a model of a solar still, make observations, and discuss how the process works. While the idea behind...
Curated OER
Estuaries, Estuarine Habitats, and Adaptations
Middle schoolers conduct research on estuaries. They design and construct an estuary, describe the physical characteristics of an estuary, and create a diagram illustrating an estuarine food web.
Curated OER
Technology of the Deep: Experiments with Buoyant Forces
Students conduct a series of experiments to study the effects of temperature and salinity on the buoyancy of an object in water. They devise ways to make floating and sinking objects neutrally buoyant.
Curated OER
Exploring Great Salt Lake
Fourth graders go on a field trip to make observations about plants in the Great Salt Lake area. They make observations about the environment and record the types of pants that are living there. The lesson is to introduce the concepts of...
Discovery Education
Sonar & Echolocation
A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...
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
Adventures With Super-Absorbers and Substance Solubility
Students understand the concepts of absorption, swellability and solubility and recognize that science is all around us in our everyday lives and is fun to explore.
Curated OER
Testing for Conductivity
Students test the conductivity of selected liquids and solids. They test the circuit by touching the two free ends of the wires together and add salt little by little recording the data after each addition. Finally, students predict...
NASA
Nasa: Exploration: Then and Now: Follow the Water Lesson
The objective of this lesson is for students to learn the location of water and the importance of water to life. Students will learn about osmosis, soil samples, salinity, and more.
Science Buddies
Science Buddies: Can Water Float on Water?
Of course it can, you say: ice is water and ice floats. And you're right. But we're talking about water in the liquid phase Can liquid water float on water? The goal of this project is to investigate what happens to layers of water with...

Noaa: More Than Salt in Salt Water [Pdf]
Realize that there is more in ocean water than just salt. Find out about the salinity of water and how changes in salinity may affect organisms living in the water.
University of California
University of California: Seawater Density & Salinity [Pdf]
Describes the properties of seawater and the variations depending on its location, e.g., near a shoreline, in an estuary, or as sea ice. Discusses the instruments scientists use to measure the density of water and explains other...
NOAA
Noaa: Ocean Explorer: Hot, Cold, Fresh and Salty
Students simulate ocean water characteristics in order to recognize that the effects of salinity and temperature are the drivers of thermohaline circulation.
