To simulate an algal bloom in Greenlake, WA add variables of run off, groundwater, sediment and the sun to the appropriate spots on the screen. This will trigger the creation of conditions that lead to an algal bloom. To add variables put the curser where you want to add the element and push "r" for run off, "s" for sediment, "g" for ground water, and the space bar for sun. To cure the algal bloom put alum "s" into the water.
This project was created as part of an environmental chemistry unit. I am still working on creating a solution to the algal bloom problem.
