You are part of your school’s environmental team. While picking up litter on the shoreline of a nearby lake, you and your team notice that there are dead fish floating in the lake. You learned from an informational tour that there used to be a large trout population thriving in the lake.


How can you bring the lake back to a healthy state? In this virtual lab, you will gather data and use a computer simulation to identify the best solution to make the lake healthy again.

Now you know how the three solutions affect the pH of the lake and the fish population.


Next, use your student guide to analyze the cost of each solution. Then, you will choose the best solution based on the information you obtained from the computer simulation and cost analysis.
