Product Details

Give students a firsthand look at ocean circulation patterns! Easy-to-use activity model demonstrates the effects of temperature and salinity on the circulation of water. First, observe the striking effect that water temperature has on ocean currents by placing cold blue water on one side of the model and hot red water on the other side. Then set up a saltwater concentration gradient to investigate ocean currents that arise when cold, dense saltwater sinks. Includes complete instructions and detailed teacher notes.

Concepts: Ocean currents, water temperature, density, salinity.
Time Required: 25 minutes
Materials Provided: Blue and red food dye, sodium chloride, acrylic tubes, drilled bottles, clay, petroleum jelly.
