More Chemistry with 2nd and 3rd Graders

We've moved with Elemental Science directions to Adventures with Atoms and Molecules, Book 1. I set the Gs to three seperate experiments on their own over the past two weeks. I was in the next room moderating the chaos, but when you consider that the materials are water and food coloring to examine molecular movements, they were just fine.  In the introduction of the book, the Gs were directed to make models of some molecules.  The picture shows their work with Easter candy, marshmellows and toothpicks.
