13.  Partner up with another group or work with your partner and use your gum drop atoms to create a molecule.  Your gum drops now represent elements… Which ones? You decide! Make each color a different element.  Try to create a Water molecule first, draw what you see, label what each is then write the molecular structure. Next try the ones on the data table or try to make your own.  You may use your periodic table for help.
