The Thermal Layers of Oceans
How much does the sun heat up a lake or ocean? Scholars use a cup and a strong lamp to investigate the heat transfer and thermal layers in the ocean to come up with the answer. They collect data and graph it in order to better understand...

Modeling Estuaries
Students create a model estuary. In this modeling estuaries lesson plan, students identify characteristics and mix water of varying densities. Students form a hypothesis, conduct an experiment, and analyze the results.
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.

Investigating Density: Heavy Ice
Students end up learning the formula for density and calculate the densities of various materials, and predict if they sink or float.
Curated OER
Liquids: Floating and Sinking
Third graders conduct an experiment. In this floating and sinking liquids lesson, 3rd graders discuss density and investigate it using syrup, vegetable oil and colored water. Students observe the results and complete a worksheet.
Curated OER
Electrolysis
Students conduct a series of experiments on water electrolysis. In this chemistry lesson plan, students explain what happens to the molecules during the process. They cite real world applications of electrolysis.

Day Two: Generating New Questions
Pupils investigate buoyancy by participating in a lab experiment. In this density lesson, students utilize vinegar and alcohol in beakers and attempt to float different items in them. Pupils analyze which items float and do not while...

Make An Egg Float!
Students analyze density. In this density lesson, students experiment with floating an egg. Students discover that salt added to water changes the density of the water allowing an egg to float.

Exploring Buoyancy
Young scholars use materials found at a resource table to design simple devices that will house instruments to take water samples from a tub of water. They design 3 instruments, each varying in density so that one will float, one will...

Addition Polymerization: Preparation of Polystyrene Using Two Types of Initiators
Advanced chemistry classes compare the polymerization of styrene using two different initators: benzoyl peroxide and aluminum chloride. Once they synthesize polystyrene, they compare the two producet for melting point and density. There...

Condensation Polymerization: Preparation of Nylon 6/6
Students participate in a lab activity in which they synthesize nylon 6/6, calculate the percent yield by mass, identify the polymer as thermoplastic or thermoset, and determine the melting point, density and end-product use of the polymer.
Polar Trec
Do You See What Icy?
Here is a lesson that kicks off with a question. "How does ice floating on the ocean act as it melts?" As learners investigate this natural phenomenon, they'll discover that it has a lot to do with temperature, salinity, and the effect...
