Waited until the last minute to get started? No problem! Each experiment in ATOMS AND MOLECULES EXPERIMENTS USING ICE, SALT, MARBLES, AND MORE follows the scientific method, and can be completed in an hour or less. Model a chemical reaction, discover how small a molecule is, and find out what happens when atoms jump from one molecule to another. Most experiments also include ideas for science fair projects in case you have extra time.
