Blue Planet: Tidal Seas
Students investigate how tides affect sea life. In this video based lesson, students view a video on how tides affect sea life. They do web-based research to find the answers to a series of questions and then play Tidal Trivia to test...
Scholastic
Study Jams! Earth's Oceans
Enjoy beautiful images and ocean facts together with the slide show, then see how much you absorbed by taking the quiz. Some of the topics covered in the presentation include water pressure, sunlight in the ocean, the names and locations...
Space Awareness
Ocean Acidification
Learn the science behind ocean acidification and its effects on ocean wildlife. Young scientists conduct a laboratory investigation that monitors the acidity level of water. While burning a candle, learners capture the carbon dioxide in...

Oceans of Fun
Here is a great hands-on activity that should lead to a greater understanding of salt water, why the ocean is salty, and how ocean waves are formed. This terrific, old-school lesson has clearly described activities, and all of the...
Curated OER
Salt Water vs. Fresh Water
Students explore why the oceans do not freeze. They explain why they think the Atlantic Ocean does not freeze. Students are given background information about what they are doing. They create a hypothesis about what they believe...
Curated OER
Why Is The Sea Salty?
Students observe how salt concentration increases in water and how salt remains after water evaporates. In this salty sea lesson plan, student use rock salt, water, containers, and strainers to observe that salt increases each time new...

The Movement of Ocean Water-Science Puzzlers, Twisters & Teasers
In this earth science worksheet, students complete 19 questions about oceans and the movement of ocean water in the form of puzzles, word scrambles, and brain teasers.
Curated OER
Knowledge Quiz
In this oceans quiz worksheet, students complete a 10 question multiple choice quiz covering a variety of concepts related to the ocean.
Curated OER
To Be Salty Sea Ice Or Not
Students explore what type of solutions freeze. They design their own experiments to compare how fresh water and salt water freezes. In addition, they write their observations in a journal and complete analysis questions.
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 activity students create saline solutions, layer them and observe how the water becomes different temperatures in different...
Curated OER
Introduction to Coral Reefs
Students identify locations of coral reefs, both in the water and around the globe, identify relative depth of corals in the ocean by observing behavior of cold and warm saltwater, and create models of coral reefs.
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
Is the Hudson River Too Salty to Drink?
Learners explore reasons for varied salinity in bodies of water. In this geographical inquiry lesson, students use a variety of visual and written information including maps, data tables, and graphs, to form a hypothesis as to why the...
Curated OER
Lesson tow
Students study the ocean and its characteristics. For this oceans lesson students complete a lab activity and are able to predict temperature of certain depths.
Curated OER
A Funny Taste
Students participate in a demonstration that illustrates the relative amounts of salt in various bodies of water including the Dead Sea, Sallt Lake, Ocean water and distilled water. They taste and compare various mixtures.
Curated OER
Sea Activities
Students explore the sea. In this biology lesson plan, student investigate sea creatures, and sea water. Students discover how to convert sea water into fresh drinking water as well.
Curated OER
Out of the Deep
Students observe, describe, and record characteristics of ocean animals (mammals and fish) and sea shells. They conduct an experiment comparing and contrasting sugar water, salt water and fresh water and create a mural of coral reef...
Curated OER
Investigating the Effect of Salinity on the Density and Stability of Water
Water with varying amounts of dissolved salt are dyed and then used to compare densities. The objective is to discover the effect of salinity, and therefore density, on ocean water on the stability of the ocean. Many branches of science...
NOAA
Please Pass the Salt
Salinity is the focus of two experimenters that work to answer the question, How does salt change the physical properties of water? Super scientists compare the freezing rate of salt and fresh water, combine the two waters to observe how...
Curated OER
Properties of the Ocean: Change
Students research and create a visual presentation on the seasonal salinity of the Earth's oceans. They apply the research in a simulation of a lab disaster in which they must relabel ocean samples.
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...
Curated OER
Water, Water Everywhere, and Nary a Drop to Drink!
Students sing the continent song and locate oceans between the continents on a map. They read "They Earth is Mostly Ocean" and copy notes into their journals. They watch a demonstration of water and saltwater evaporated to see what is...
Curated OER
Density Stratification and Ocean Circulation
Students examine how circulation currents of the ocean. They use a tub of hot and cold water to demonstrate the currents. They discover how salinity and temperature of water affect its movement.
Curated OER
Fresh or Salty?
Learners explore water bodies on the planet Earth and their various uses and qualities. They examine several ways that engineers are working to maintain and conserve water sources and think about their role in water conservation....
