Investigates the effects of using scientific apparatus versus household objects on the accuracy of primary school children in a simple titration exercise. Indicates no significant difference between the accuracy obtained using the two types of apparatus at the beginning, but improved performance for children using scientific apparatus by the end.…

Describes a hands-on lesson in magnetism designed to be used with upper elementary grade students. Emphasizes structured experiences which involve the student in measuring, data collecting, graphing, and extrapolating information. (TW)

Describes an after-school science program, "Hands On Science," in which children from kindergarten though sixth grade discover that the application of science and technology begins with simple materials, a need, and their minds. (Author/BB)

Describes some of the characteristics of "herps" (amphibians and reptiles). Contains teaching activities dealing with ancient herps, learning stations that encourage sensory experiences with herps, and games, puzzles, and a dramatic play about herps. Includes reproducible handouts designed to be used with the activities, as well as a quiz. (TW)

Describes a program in the Bellevue (Washington) public schools in which elementary and middle school teachers and students raise coho and Chinook salmon in the classroom and later release them into a nearby stream. (TW)

Offers perspectives on how conceptual changes actually take place in students. Proposes that elements of Kuhn's concept of scientific paradigms and Wittgenstein's concept of the "language-game" be considered in an analysis of conceptual change. Explains how components of these models relate to science learning. (ML)

Discusses a study which explored the possible value of the history of science to understanding student misconceptions. Focused on photosynthesis and examined relationships between students' conceptual difficulties and the transformation of concepts through time. Student responses suggest that the history of science can be used to anticipate…

Advocates and defines a contextual science approach which emphasizes holistic investigations of phenomena. In the approach, small groups of teachers (each with an area of expertise) would be in charge of instruction. An example of the approach (with suggested roles for each specialist) related to the world food supplies is given. (DH)

Discusses development, goals, and phases of the Resources Management Education Program. The program, designed to create a basic awareness of conservation and natural resources management issues for primary schools in Latin America, is taught in conjunction with the life and physical sciences. (DH)

Examines the influence of courses in the sciences and in science teaching methods on the attitudes of preservice elementary teachers. Data collected over a three-year period indicated that the preservice teachers had positive changes in attitudes toward science and science teaching while taking science and science methods courses.
