After day 2 of cleaning the water, our water is looking MUCH cleaner than yesterday. We were able to remove quite a bit of items, but we had a lengthy conversation about what were able to actually prove was removed and what wasn't. We're not really sure about some of the stuff...so we'll be thinking about other investigations we can do to prove that some of the items are maybe there. There's been lots of conversation around the size of the holes in the tools we used, but we're not convinced that all the materials had holes.
We can't prove what happened where the salt, sugar, citric acid, vinegar, and for some groups, the oil.

We also revisited our Driving Question Board to see which questions we could answer now from our investigations in which we cleaned the water. Mrs. Brinza was also pretty motivated to save what was filtered out to send to the "landfill" and the water that was as clean as we could get it!
