One More Aquifer Model

Paul and my husband,  Rob, built an aquifer model this afternoon.  They used a copy of the Scholastic Model, part of How Water Works, and The Awesome Aquifer Slideshow to make the model.  The project took roughly an hour; I had made up a kit with the gravel, sand, straws, pump, charcoal, rubber bands, etc. before they started.  Paul was more enthusiastic about the edible aquifer than this model.  I should have promised the edible aquifer after he built the model aquifer.  Still, I think he has the concept.  I posted the photos to Classroom and deleted them after.  They didn’t load!  Aaarrrrrrggghhhh!  Paul just told me he isn’t doing the model again.
