Curated OER
Learning Lesson: Salt 'n Lighter
Students participate in a demonstration showing that as salinity increases density increases as well. They also examine the different densities of air. They discuss the amount of water displaced by large ships.
Curated OER
Texas Estuary Project
Students practice the proper lab techniques of coring, seining, taking temperatures, and salinity. Students analyze and graph data. Students write a 3 part essay and correctly draw and label a food web of their field site.

Brine Shrimp Survival
Middle schoolers develop an understanding of how growth and survival of an organism depends on physical conditions. They design an artificial environment in which brine shrimp can thrive. Students determine the optimum salinity for...
Curated OER
Hatching Brine Shrimp
Third graders investigate the environment that is considered favorable for brine shrimp hatching. The salinity level is of particular interest in the observations because the optimum level is needed for survival. They make daily...
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
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 instructional activity is to introduce...
Curated OER
Water Quality
Students examine the YSI and the water properties that it measures. They identify the different properties of water pH, DO, temperature, turbidity, and salinity and determine why it is important for them to test these parameters.
Curated OER
Density Currents
Students experiment with currents caused by temperature variations that simulate the origins and flow of polar bottom currents. They discover water density is affected by temperature and salinity, resulting in deep water currents.

Brine Shrimp 1: Hatching Brine Shrimp
Middle schoolers develop an understanding of how the growth and survival of an organism (brine shrimp) depends on physical conditions. This is accomplished by designing an experiment to determine the optimum salinity of water needed to...
Discovery Science Center
Kindergarten Observing, Comparing and Contrasting
Although this is a science lesson, it can be adapted to help meet Common Core standards in math as well. Starting scientists describe physical properties of objects and explore three forms of water. To address the Common Core, they can...
Curated OER
It's the Law
Students explain various scientific laws used in SCUBA diving. In this theory based lesson plan, students examine and explain how temperature, density, and salinity relate to SCUBA diving using various scientific laws to engage their...

Lesson tow
Students study the ocean and its characteristics. In this oceans instructional activity students complete a lab activity and are able to predict temperature of certain depths.
Curated OER
A “Salting” Solution
Ninth graders investigate the factors affecting solubility. For this chemistry lesson, 9th graders differentiate solvent and solute. They give examples of real world application of solutions.
Curated OER
Food Forensics: A Case of Mistaken Identity
Pupils develop an experiment to test a hypothesis. They use their knowledge of antigen-antibody specificity to develop a hypothesis. Students articulate that the antibody-antigen specificity is one part of the immune system. They develop...
Curated OER
Telemetry
In this telemetry instructional activity, students will read about how telemetry works and the different ways that scientist use telemetry to gather data. Students complete 2 short answer questions based on the reading.
Curated OER
An Oceanographic Proxy
Students conduct experiments on a sample of sea water. In this oceanography lesson, students inquire how conductivity is used to approximate the salinity ocean water. Students construct their own conductivity meters and test...
Curated OER
Water Quality Testing
Student explore factors affecting ecosystems. They test local water samples for pH level. After creating a methodology for data collection, they collect data, compare results, and draw conclusions based upon results.
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
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
Bacterial growth
Students explore the exponential growth and decay of microbial populations in relation to the organism tolerance ranges in their environment, They observe the impact of changing variables which can affect microbial populations.
Curated OER
Exploring the Great Salt Lake
Third graders participate in a scavenger hunt, looking for things that are unique about the ecosystem in and around the lake. They observe and describe a variety of habitats and distinguish living and nonliving elements of...
Curated OER
