Physical Changes and Conservation of Matter
Description
What happens when sugar is dissolved in a glass of water or when a pot of water on the stove boils away? Do things ever really disappear? In everyday life, observations that things "disappear" or "appear" seem to contradict one of the fundamental laws of nature: matter can be neither created nor destroyed. In this session, participants learn how the principles of the particle model are consistent with conservation of matter.
