Description:

Create hydrograph and explore changes in physical parameters on form of hydrograph. Set up is easy: water is sprinkled into a model watershed (sand in pop bottle) and allowed to dribble onto cheap digital scale. Students record weight of water over time, convert to volume, and then create hydrograph. More complicated pop-bottle watersheds can model effect of urbanization, antecedent moisture, changes in precipitation, changes in "soil" porosity/permeability, etc. SEE TEACHING MATERIALS AND TIPS FOR DETAILS!
