We're starting to see all these ideas come together and we're so proud of what we've figured out. An elephant can't fit through a hole that's too small for it to step through. The larger objects we put in our water to make it dirty that didn't dissolve got caught in our strainers. Mrs. Brinza's "toy" model showed us how empty space/gaps allow some things to get caught and others to pass through--just like the holes or empty spaces in filters. We're thinking the ground is a filter, too!
We also circled back to our Twitter post from Oklahoma. She mentioned that the groundwater had to get refilled when they used all the water. We're curious how this happens so we agreed we needed to figure out more about wells. When we found a well diagram, we were surprised at how different it looks like the "Jack and Jill" nursery rhyme picture many of us envisioned to be a well! And of course there was so much to notice and wonder about this well system!

While actually going to a well would have been an incredible field trip, we're limited by a couple things. One, everyone in the city uses water from Lake Michigan, so we couldn't really ask anyone here about wells. And we're still in the middle of a pandemic, so field trips are kind of out of the question. But we did find a great video resource helping us figure out more about wells, how they're built, and how they get refilled!
