Chemistry Class - molecules are made of atoms

In chapter 2 of our chemistry book, we learned that when atoms join together to make molecules, they must follow rules!  For our lab, we used marshmallows to represent the atoms and put them together into molecules using toothpicks.  At first the girls were allowed to be creative and make whatever they wanted.  We then imposed rules for the atoms to follow, and saw that that limited what we were able to do.

Of course we ate some of the molecules when we were through!
