L-THIA: long-term hydrological impact assessment A completely on-line model produced by the EPA and Purdue Univ. Under "inputs" one can enter the land use type, soil type and amount of land, and it will tell the annual runoff for the certain land use types. Ideal as a Classroom based model in Physical Hydrology.
A site where one can enter a variety of specifications and determine the altitude that a model rocket will hit. It also gives a few good links to sites that describe the process of this type of model.
Software and Demographic Models offered by NIDI (netherlands interdisciplinary demographic institute). A number of nice models and software programs; some are free.
One of the models found on teh above page. It's a nice Java Model which allows the user to set different parameters and draws really nice graphs and demographic pyramid.
