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...
Curated OER
Finding the Deep Water Masses of the Atlantic Ocean
Students describe the role of density in driving deep ocean currents and the density layers of the ocean. They determine that the ocean is one continuous body of water with global currents that interact, with water surrounding all...
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
Is the Hudson River Too Salty to Drink?
Students 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
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
Sea Water Freeze
Middle schoolers 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
Curated OER
Lesson tow
Learners study the ocean and its characteristics. In this oceans lesson students complete a lab activity and are able to predict temperature of certain depths.
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
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
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
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...
Curated OER
Biocomplexity Lab Activity: Density and Buoyancy of
Students investigate how the density of water changes the buoyancy of
water. Students create a hypothesis about what will happen when placing the
egg into the water.Students can research online different bodies of water (The Red Sea, The...
Curated OER
Water Currents
Students demonstrate how ocean currents are influenced by changes in density. They discover that temperature and salintiy affect density as well. They participate in a short experiment to end the instructional activity.
Curated OER
The Weight of Water
Students examine how salt water is more dense than fresh water. They discuss how manatees need to float and sink, conduct a sink or float experiment, and conduct an experiment with eggs and salt and fresh water.
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
Elements of Chemistry: Solids, Liquids and Gases
Young scholars predict if icebergs melting has an effect on the sea level rising. In this global warming lesson students complete an experiment to see the effects of melting icebergs and write a conclusion on their data collected.
Curated OER
Biocomplexity Lab Activity: Creating Salt Water
The activity 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 water....
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.
