Water Quality Monitoring
Pupils comprehend the four parameters of water quality. They perform tests for salinity, dissolved oxygen, pH and clarity or turbidity. Students comprehend why scientists and environmental managers monitor water uality and aquatic...
Curated OER
Water Currents
Middle schoolers 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 lesson.
Curated OER
Driving Currents
Students conduct a variety of investigations to see how water, heat, and salinity affect the flow of the world's ocean currents,as well as, explore many factors that affect the flow of the world's ocean currents. They also describe in...

Why Could the Hindenburg Float?
Tenth graders experiment with floating and sinking objects and heavy and light liquids, using correct terms, like density, to explain what happens. In this Hindenburg activity, 10th graders watch a demonstration called the invisible...
Curated OER
Ocean Currents
Learners discover the geography of Earth by analyzing water currents. In this oceanography lesson, students create visual references on a map of the globe where and why major ocean currents are moving water. Learners conduct a water...
Curated OER
Estuarine Currents
Students experiment observing a demonstration on models of density-driven currents which are typically found in an estuarine system of water flow. They compare/contrast water temperature and salinity to the formations of estuarine currents.
Curated OER
How Much Water in Snow?
Students determine the volume of water in a given amount of snow. They calculate a ratio for water volume per snow volume.
Curated OER
Sewer Lice
Students observe demonstrations that show adhesion, cohesion, equilibrium density, pressure of gases and solubility. In this gases lesson plan, students observe a demonstration of raisins, spaghetti, and popcorn moving up and down in...
Curated OER
The Heat of Fusion of Ice
Students measure the heat of fusion of ice. In this heat of fusion lesson plan, students use a calorimeter or Styrofoam cup and thermometer to measure the change in temperature of the water in their calorimeter. This allows students to...
NorthEast Ohio Geoscience Education Outreach
Investigation of Plate Boundaries
Demonstrate the movement of lithospheric plates due to convection in Earth's mantle. Learners then model the movements that occur along plate boundaries using colored clay.
Curated OER
Atmospheric Processes -- Convection
Students work together to discover how temperature changes can affect the density of water and air. They make predictions on what they believe is going to occur. They answer questions to complete the lesson.
Curated OER
Ships 2: What Floats Your Boat?
Students design, build, and test the specifications (water displacement and load line) for a model boat. The lesson focuses especially on integrating design principles with inquiry-based experimental skills.
Curated OER
Not a Drop to Drink
Students design an experiment to determine which liquid is water. In this chemistry lesson, students perform the experiment as outlined in their design. They record observation and formulate conclusion.
Curated OER
Rain Drops
Pupils examine drops of water on several materials used on the outside of buildings. They make selective observations on and compare plastic, wood, brick, metal, roof tiles and glass.
Curated OER
Boy, Is That Buoyant!
Fourth graders see that salt increases the density of water and creates a condition wherein objects are more buoyant than would be expected under normal conditions. They describe the relationship between heat energy, evaporation and...
Curated OER
Estuarine Currents
Students explore an estuarine system to gather data on density driven currents. This type of current is contrasted with temperature and wind driven currents.
Curated OER
Investigating Convection Currents
Students examine how differences in the temperature and salinity of the water help create ocean currents. They perform an experiment which shows how temperature affects the circulation of ocean water.
Curated OER
Get to know H2O!
Pupils investigate scientific concepts and inquire about physical states of matter. The transition of water is considered and is easy to facilitate because of its abundance and often observed physical changes.
Curated OER
Paper Chromatography
Learners use this design the illustrate how ink can be separated into its component chemicals using paper chromatography. They use five unknown samples of ink on pre-labeled chromatography strips are provided to students. Learners use...
Curated OER
WHY DO SOME THINGS FLOAT WHILE OTHERS SINK
Young scholars explore how density can cause things to sink or float by experimenting with a jar, oil and corn syrup.
Curated OER
Pipeline to the Coral Reefs
High schoolers discuss the relationship of density to stratification. In this marine science lesson plan, students create a model of upwelling events using cold and warm water. They discuss how water phenomena affect coral reefs.
NOAA
El Niño
El Nino, La Nina ... and the Santa Maria? The 11th installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program explains the mechanism of El Nino/Southern Oscillation. Pupils use previous data to determine...
