We decided that because of Chicago's VAST amount of impermeable surfaces, limited groundwater documented on the USGS maps, along with the fact that we don't see lots of well caps around the city, we probably don't get our water from groundwater. However, this got us thinking about where we actually do get our clean water from, and we spent time developing some initial models. Here are some examples of student work:
We've got lots of ideas that we summarized into the following as a class:
Since we don't have a lot of agreement and there's lots of ideas floating around, we decided to think of investigations we could do to determine the two parts of our question:
1. Investigations to figure out where our clean water comes from.
2. Investigations to determine if the water we get from our faucets is the same or different from the water at the source.
By the looks of it, it looks like Mrs. Brinza has some intense HW tonight to figure out how to make these investigations happen!
