Students suggested we put a camera down INTO THE GROUND, but that wasn't really possible. But Mrs. Brinza turned to youtube and realized there was some work being down by well diggers that could help us see what happens to the water when it goes down deep into the ground, entering a well.
We had a really intense conversation about how the water that gets deep into the ground can actually get rid of anything that's in the water by trapping it in the really small spaces that are between the pieces of soil. This was MIND-BLOWING to us that "dirt" or "dirty things" could actually clean water!
We decided to put this new found knowledge into action and design our own filters to clean the dirty water we had sitting on the window ledge. Students had combinations of sand, soil, and gravel to use, and boy did their water get cleaner!
