So we've expanded our models are have looked specifically at groundwater. We know how it gets down deep into the earth, and we know how the different earth materials filter it. But what about places like where we live? Chicago does not certainly look like the other places that have groundwater.
So we decided to test some of these surfaces by pouring water on them. Here's a rundown of our experiments and where it took us!

Permeable vs. Impermeable
We figured out that many earth materials are permeable and water can infiltrate them!
