Matter is often grouped by its properties, and these properties come in two categories: physical and chemical properties. This experiment is actually a series of mini-experiments that will examine several physical and chemical properties of matter. Additionally, these mini-experiments will help students understand and identify both the physical and chemical changes that matter can undergo. Taken together, these experiments represent a complete lesson on the topic of chemical and physical change.

When you completely submerge the cup, upside down, you may be shocked to see that the paper towel stays totally dry!

By combining the two reactants in different ratios you can explore how there is an ideal reactant ratio to get a maximum amount of carbon dioxide. This introduces the chemical concept of limiting reagents and stoichiometry. This experiment has multiple levels to it, meaning it can be a good experiment for any level from 3rd grade to college freshmen.
