The one minute quiz seems to stimulate interest and attention during the lecture. The student is alerted to recognize the quiz material as it is used in the lecture. 1 t encourages review of algebra, geometry, and trigonometry, the simpler integrals and differentials, and the use of c.g.8. units. Most gratifying has been the interest in better understanding the periodic table and its prediction of various physical and chemical properties. The quiz has led to many informal discussions during the weekly laboratory period and has encouraged many students to survey the periodic table to invent possible questions. Some sample questions are: What are c.g.s. units of force (or energy, or pressure)? Work equals JPdV; does work also equal J V d P ? List the man-made elements with atomic number less than 92. Which has the higher crystal lattice energy: argon or xenon?
