Curated OER
Science Lesson #2
Fourth graders explore and experiment with objects that float to see if they float differently in salt water or fresh water. After the experiment, they write a paragraph in their science journal explaining how fresh water and ocean water...
Curated OER
Why is the Sea Salty?
Students conduct a hands-on activity to investigate salt concentrations in water and how salt remain after water evaporates. They can also do a Saltwater Painting to once again observe the evaporation. process.

New Jersey Estuaries
Young scholars experiment to discover that salt water is denser than fresh water by creating color coded solutions. They examine how heavy rainstorms and high tides develop layers of different degrees of density.
Curated OER
Understanding Salinity
Young scholars 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...

"Eggs-perimenting" Fun
Students dissolve salt into water, place an egg into a glass of salt water, observe and record observations, make a scientific hypothesis, summarize what they studied from this hands-on experiment. They share their ideas and findings...
Curated OER
Make An Egg Float!
Students analyze density. In this density lesson plan, students experiment with floating an egg. Students discover that salt added to water changes the density of the water allowing an egg to float.
Curated OER
Ice Cream
Students are shown an experiment making ice cream while discovering the freezing point depression. There are questions for students to answer after the demostration.
Curated OER
Slippery, Slippery Ice
Students investigate how salt affects ice by experimenting in class. In this water properties lesson, students utilize a penny, salt and pans of ice to examine the sliding ability of a penny across a layer of ice. Students then place...
Curated OER
The Salt Water Connection
Students investigate the various factors that influence the Pacific Ocean and Monterey Bay, California. They watch a video about Monterey Bay and take notes, and conduct research and write a report about a specific organism living in...

Teacher's Guide For: Water Temperature and Salinity Experiment
Students experiment with water density, temperature and salinity. In 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
DNA Extraction Laboratory Experiment
Students will visualize how DNA is extracted from cells by performing a simple laboratory experiment. They will then use this knowledge to further understand how scientists are using DNA extraction to try to clone human cells, and to...
Curated OER
A Salty Experiment
Students study salty and fresh waters. In this harbor estuary lesson students complete a lab activity on salinity and describe what happened.
Curated OER
Towers of the Lost City
Middle school marine scientists compare the pH change in distilled and saltwater as acetic acid is added one drop at a time. Then they compare the pH change in both when sodium hydroxide is added. This experiment demonstrates the...

Is It Safe to Go In? Water Quality of Bathing Areas in the EU
Using your senses, apprehend the effects of contaminants in water. With a global focus, young scientists conduct a safe experiment by tasting sugar and salt water with different dilutions. After reviewing threshold limits, learners write...
American Chemical Society
Why Does Water Dissolve Salt?
Individuals explore solubility by modeling how water dissolves salts. They then view a video and compare how well water and alcohol dissolve salts, relating their comparisons to the structure of each molecule.
Curated OER
Will It Grow?
Fifth graders conduct experiments involving plants. In this science activity, 5th graders design an experiment involving plants. Students use the scientific method to design their experiments.
Curated OER
Physical and Chemical Reactions - Factors Which Affect Reaction Rate
A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the...
Curated OER
Celery Lab
How do sugar and salt affect celery's mass, width, and flexibility? Using simple household ingredients, young scientists will perform a controlled experiment to find out. The lab is scaffolded through a worksheet, but there are no other...
Curated OER
Stacking Water
Learners experiment with different salinities of water using straws and different colors of water. They collect and interpret data from the experiment.
Curated OER
Oil Well That Ends Well
Focusing on the effect of oil spills on the environment, learners conduct experiments to explore this issue. First, they create an ocean environment using materials provided. Then, they make a simulated crude oil substance from vegetable...

Where's My Mummy: Preservation Techniques
To observe preservation techniques firsthand, learners dry a flower in sand and compare cucumber slices soaked in salt water for a week with slices left out to dry in the open air. Video resources (not attached) include one about mummies...
Curated OER
Note Taking And Skills And Lab Reports
Students perform simple and fun experiments to use the scientific method, take careful notes, and write a lab report. They first make and test a hypothesis about how many drops of water they can fit on the face of a penny and then test...
Curated OER
Temperature Effects on Solubility
Students determine the solubility of salt in water at three different temperatures and graph the results. They use the following skills: observing, inferring, and graphing.
Curated OER
The Salt Water Connection
High schoolers explore the hydrological cycle and oceans. They determine the factors that influence the Pacific Ocean. Students research an organism found in Monterey Bay. They describe the organism's biome and ecological factors that...
