Bring the Earth Sciences to life and satisfy National Science Standards with one of these Density Flow Models. These demonstration models are useful for simulating the realistic flow of fluids in nature such as weather systems, ocean circulation, and plate tectonics. Kits come with all supplies, set-up instructions, student activity masters, and answer keys.

ORIGINAL Model Challenge students to use scientific inquiry techniques to explore geology, meteorology, freshwater, and saltwater systems. Using colored fluids, students can visualize abstract concepts related to plate tectonics, sea-floor spreading, air masses, fronts, air pressure, winds, oceans currents, thermoclines, haloclines, upwelling, and more.

JUNIOR Model Engage students with dramatic siumlations of the earth's dynamic natural processes. Accompanying activities encourage students to ask: "What if...?" and watch as a teacher tests their hypotheses. Illuminated and includes nearly all the same demonstrations as the ORIGINAL model except sea floor spreading and upwelling.
