Earth Science
Soil, Porosity & Groundwater
Pour water through gravel, sand, and soil. Which holds more, which drains faster, and where does a leak spread?
Environmental
Watersheds, Runoff & Land Use
Rain on a landscape model. Clear it, plow it, terrace it, pave it, and rain again. Where does the water go?
Environmental
Water Quality & Eutrophication
Add fertilizer or farm waste to a pond model. Follow the algae bloom to the fish kill, and test for coliforms.
Environmental
Toxicology: Dose–Response & Biomagnification
Find the LC50 of brine shrimp in a 24-hour dilution series, then dose model animals in mg/kg to find an LD50. Why are they different numbers? Then follow a pesticide up a food chain.
Environmental
Design a Water Treatment Plant
Chain screening and settling, aeration, a tertiary step (chemical phosphorus removal or a constructed wetland), and disinfection. Can your plant meet the discharge limits for solids, BOD, phosphorus, and coliforms?
