Why Lesson Planet?
A great way to learn about molecular structures is to make a model. Gumdrops and toothpicks are used to construct crystal models. The models are based on theories of crystal shapes that occur because of positive and or negatively charged ions and the three rules of mineral structure: geometric stability, electrostatic stability, and polarizability. Chemical equations and guidelines are provided to make this a very good, not to mention tasty, lesson.
