Making a Foam Gnome!

on December 14, 2015

4th Graders have been exploring the differences between mixtures and compounds in science.  Students observed a chemical reaction when they added an acid poly A to a base poly B.  The product created was polyurethane foam.  When they mixed the two liquids they created a new compound after observing air bubbles, heat, a change in state, and a change in color.  Students loved decorating their foam gnomes in the maker space at the end of class.
