Discusses six educational and economic reasons for using demonstrations in a high school chemistry classroom. Also discusses reasons for doing lecture demonstrations as an integral part of college chemistry instruction. (JN)

Active engagement in the classroom is one of the best tools available for overcoming conceptual difficulties. Science educators agree that students of all ages learn more by participating actively in the interpretation of scientific phenomena (NAS 2003; NSF 1998). In this article, the authors describe demonstrations in class using paper wads as an…

Describes the philosophy of a high school chemistry teacher, providing examples through classroom experiences, with emphasis on the use of demonstrations as instructional aids. Specific stoichiometry and conductometric titration demonstrations are discussed. (CS)

Described are different chemistry curricula that use lecture-experiments. Different components are discussed within the lecture-experiment format, such as determinism, memory, note taking, descriptive chemistry, and holistic chemistry. Also discussed are different personalities in chemistry education. (DS)

Presented are some techniques aimed at motivating more high school students to take elective courses in chemistry and physics. Discussed are teacher attitudes about who should study chemistry and physics, preassessment of new topics, and the importance of communication between science teachers. (KR)
