Exploring Molecules

Grade Level: 6

Objective: To better understand molecules and surface tension through a series of hands-on demonstrations

We've been studying atoms and molecules in science over the last couple weeks.  Recently we did an experiment using milk, food coloring, and dish soap.  We poured food coloring in milk then added a drop of dish soap and watched the dye swirl.  We learned how soap is bipolar, enabling it to break the surface tension on the milk.  The kids had fun drawing different kinds of molecules and watching the ways in which they behave.
