Belief that peoples personalities could be described by the bumps on their heads (REALLY!) • Superstition- Belief that things or rituals bring good (or bad) luck

  9. What is Chemistry? • Chemistry is a science that has changed over time as new discoveries and experiments occur. • The discoveries are tested over and over to be sure the information is reliable • Chemistry is the study of the composition (make-up) and structure of materials (matter) and the changes they undergo.
