The Oxygen Sag Simulator

Students examine the impact of pollution on water and land ecosystems. The unit covers point and nonpoint source pollution, waste management, and the biological effects of toxins like endocrine disruptors. The Oxygen Sag Simulator turns that idea into something you can manipulate directly and watch respond.

Students examine the impact of pollution on water and land ecosystems. The unit covers point and nonpoint source pollution, waste management, and the biological effects of toxins like endocrine disruptors. It focuses on Point vs. Nonpoint Source Pollution, Eutrophication and Dead Zones, Endocrine Disruptors, Bioaccumulation and Biomagnification, Solid Waste Management and Landfills, Sewage Treatment Processes from the “Unit 8: Aquatic and Terrestrial Pollution” section.

The “Waste Load (L₀)”, “Flow Velocity”, “Reaeration (k₂)” sliders change the key inputs; you can drag elements directly on the canvas. Every change updates the visualization in real time, so you can see exactly how each variable affects the outcome.

AP Environmental Science is a college-level, interdisciplinary course that explores the scientific principles, concepts, and methodologies required to understand the interrelationships of the natural world.

You'll build intuition for Point vs. Nonpoint Source Pollution, Eutrophication and Dead Zones, Endocrine Disruptors, Bioaccumulation and Biomagnification, Solid Waste Management and Landfills, Sewage Treatment Processes — and, crucially, see how they behave when you change the inputs, which is hard to get from a textbook or lecture on AP Environmental Science alone.
