Demonstrate important density concepts to an entire classroom. Challenge students to use scientific inquiry techniques to explore geology, meteorology, freshwater and saltwater systems.
Using the illuminated flow of colored fluids, students can visualize abstract concepts related to plate tectonics, sea-floor spreading, air masses, fronts, air pressure, winds, ocean currents, thermoclines, haloclines, upwelling, El Nino and more.
