Bring the Earth sciences to life and satisfy National Science Standards (NSS) with one of these versatile density flow models. Teacher developed, these educational demonstration models are the most complete and useful tools for simulating the realistic flow of fluids in nature (i.e., weather systems, ocean circulation, mountain building, and plate tectonics).

• Density flow models are available in two sizes: Regular and Junior
• Complement Earth science, physical science, general science, and integrated science curricula
• For grades 6 to 12+
• Fascinating demonstrations to observe for multiple science units
• Accompanying manuals include setup instructions, student activity masters, and answer keys
• Recently updated in 2024 with new isostasy demonstrations and activities

With the full-size kit, 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, isostasy, sea-floor spreading, air masses, fronts, air pressure, winds, ocean currents, thermoclines, haloclines, upwelling, El Nino, and more.

At half the size and about half the cost of the standard unit, the junior model is also illuminated and includes nearly all the same demonstrations (except sea floor spreading, isostasy, and upwelling).

Engage students in small groups with dramatic simulations of the Earth’s dynamic natural processes. Accompanying activities encourage students to ask: 'What if…?' and watch as a teacher tests their hypotheses.
