Field notes

LeverScope teaches stocks, flows, and links through examples ranging from a bathtub to traffic and predator-prey relationships. Its homepage presents a live bathtub model and says visitors can open, change, and run library models. Learning material is aimed at roughly age 10 and up; the site also describes scenario comparison and robustness testing for engineers and managers, though those capabilities are not verified by the extracted page.
