So after attempting to clean the dirty water we made, and coming to consensus, we hands down agreed that the groundwater is cleaned by the earth materials it travels through! We even wanted to do our own models on a larger scale (but didn't get much luck since it's still just WAY too small compared to the earth's ground!).
Our next steps were to figure out more about our own water...and this prompted for new investigation ideas:
Through research and Google Maps, we found out the following:
Through research and Google Maps, we found out the following:
1. Our source of water here in Chicago is Lake Michigan.
2. Water is removed from Lake Michigan by a water crib!
3. There's a building near Lake Michigan's shores called a Purification Plant!
Many students had also wanted to test water as a way to figure out more about it...
So we tested water both in class...and outside of class! Mrs. Brinza went all the way to the Lake for students! Click HERE to see the videos and see the comparison results!

Now we're really wondering what's going on at this Purification Plant since some of the substances we measured in the water decreased and others increased! This means we're thinking that not only are things removed from Lake Michigan's water, but some things are added!
