Clay-Loam-Sand

Following our settling cups observations today, kids noticed that the particle size of the clay had greatly reduced.  We talked about uses for clay, and how water would be needed.  Storm Lake used to have a brick factory, using clay from our lake to make the bricks.  Joshua gave it a try!
