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
Current Interactions
High schoolers design an experiment to see how wind, temperature, and salinity work together to influence ocean currents and present it in a report format. They explain to their classmates how experiment findings relate to ocean currents.
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.

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.

A plethora of information about the blue crabs of Chesapeake Bay will amaze and delight your marine biologists. They learn, through direct instruction, about the characteristics and life cycle of this fascinating arthropod. A highlight...
Curated OER
Density Dynamics
Students set up working models demonstrating lake turnover and the formation of deep water masses in the oceans.
Curated OER
Properties of Fresh and Sea Water
Students work with three stations to demonstrate the properties of water. They explore water's boiling point, freezing point, and its ability to store heat.
Curated OER
Arkansas State Rock
Here is a lesson which shows the value of a mineral called bauxite to Arkansas during the early 1900's. Learners relate the five themes of geography to the history of bauxite and aluminum production in Arkansas. For teachers of...
