Nuclear Fission Reactor
Operate a Pressurized Water Reactor (PWR). Control the fission chain reaction using control rods and monitor core temperatures to prevent a nuclear meltdown.
Plate Tectonic Boundaries
Examine tectonic plate interactions. Select Divergent, Convergent, or Transform boundaries to visualize mantle convection driving lithospheric drift.
El Niño & La Niña (ENSO)
Analyze the El Niño-Southern Oscillation (ENSO). Toggle between Normal, El Niño, and La Niña phases to observe shifting trade winds, ocean temperatures, and upwelling.
Atmospheric Circulation
Observe global wind patterns across the Earth's cross-section. Toggle the Coriolis effect to see how the Earth's rotation deflects the Trade Winds and Westerlies within the Hadley, Ferrel, and Polar cells.
Wastewater Treatment
Examine the physical, biological, and chemical stages of sewage treatment. Understand the role of aeration and activated sludge in reducing biological oxygen demand (BOD).
Soil Texture Triangle
Determine soil classification using the USDA Soil Texture Triangle. Adjust Sand, Silt, and Clay percentages to find the precise intersection point.
Drinking Water Treatment
Step through the municipal drinking water purification process. Observe coagulation, flocculation, sedimentation, filtration, and disinfection.
Biomagnification Simulator
Introduce a trace amount of a persistent toxin like DDT into an aquatic ecosystem and watch as the concentration multiplies exponentially up the food chain to the apex predator.
Island Biogeography Model
Simulate the Theory of Island Biogeography by adjusting island size and distance from the mainland. Observe how immigration and extinction rates determine the equilibrium number of species.
LD50 Toxicity Curve
Analyze dose-response sigmoidal curves to determine the Lethal Dose 50% (LD50) of various chemical toxins. Understand acute toxicity and threshold levels.
Survivorship Curves
Compare Type I, Type II, and Type III survivorship curves. Understand the distinction between K-selected and r-selected reproductive strategies across the animal kingdom.
Demographic Transition Model
Greenhouse Effect & Global Warming
Solar & Wind Energy Comparison
Food Web & Energy Flow
Ozone Layer & UV Radiation
Carbon Cycle Visualizer
Eutrophication & Hypoxia System
Trigger an ecological collapse. Release nitrogen and phosphorus Agricultural Runoff to force an Algal Bloom, then watch the horrific spike in Biological Oxygen Demand (BOD) that strips Dissolved Oxygen (DO) and causes an aquatic Dead Zone.
Aquifer Drawdown & Saltwater Intrusion
Examine groundwater dynamics under agricultural duress. Over-pump the well to witness the Cone of Depression collapse the water table, eventually drawing up toxic saltwater from the deep aquifer and ruining the well.
El Niño Southern Oscillation (ENSO)
Visualize the Pacific Ocean trade winds, thermocline shift, and upwelling mechanisms that govern El Niño and La Niña climate phases.
Trophic Energy Pyramid
Observe the 10% Rule in action: Energy flows in one direction and 90% is lost at each step, explaining why ecosystems rarely support chains longer than 5 levels.
