Modeling Dissolving and the Dirty Water Post-Filtering!

10/15/2017

 
Before we finalize our thinking about this dirty water that we tried REALLY hard to clean, we've determined that the water has stuff in it that's too small to see.  Stuff is there...and it's dissolved.  It's making us think about this water that leaves the wastewater treatment facility.

Students were asked to expand their thinking into modeling salt dissolving.  Here's what some students were thinking...

Modeling Salt Dissolving

Modeling the Dirty Water (with vinegar and the dissolved solids)

And while we've become more knowledgeable about modeling and everything made of "pieces," we're STILL thinking about that water that's been cleaned ​ at the wastewater treatment facility. What exactly is in it that we can't see?  Where does it go if there is still stuff in it they can't get out!?!?!?!

    There's nothing like a nice cold glass of water on a warm day.  I kind of take advantage of that clean water quite often...
