This curriculum module is designed to open an introductory high school chemistry course. The first activity uses samples of the chemical elements, magnets, and conductivity testers for students to develop skills in drawing conclusions--and in evaluating the usefulness of such conclusions. In the second activity, paralleling Mendeleev's assembly of a periodic table, students create their own classification scheme of elements using "element cards" (their real identities are disguised). This is an excellent opportunity to discuss the landmark historical development and the many ways to represent the periodic table. In the third, more open-ended activity, students learn introductory laboratory techniques and a specific format for recording observations -- reflecting the decades of work on elements that led to the discovery of periodicity.
