Describes two experimental procedures and the reactions suitable for teaching the principle that catalysts do not affect the position of equilibrium. (GS)

Proposes that teachers introduce their students to the process by which Federal and State decision-makers propose rules and regulations for implementation within society by exposing them to the "Federal Register" and their state's equivalent publication. (MLH)

Describes a science activity in which students are given an opportunity to consider the values of open space. The program includes direct involvement as communicators of feelings and facts, leading students to a position of making wise decisions for land use in the future. (EB)

Describes a science activity in which any and all elementary school students can become involved and enjoy success. Various activities centered around a student-devised mini-garden are proposed. (EB)

Describes an activity which incorporates topographic map interpretation, soils analysis, hydrogeology, and local geology in a five-week series of exercises for an introductory college earth science class. (CP)

Advocates a field seminar program in which prospective earth science teachers, as well as other student participants, may earn college credits for taking part in field experiences. (CP)

Advocates the use of elementary science materials in teaching three-dimensional geology concepts. Elementary science materials from six sources are analyzed for uses in geological considerations. (CP)

Provides an account of the way in which one small university has coped with limited funds and a small staff to provide laboratory activities for freshman physics courses. (CP)

Describes three dialog programs which have been used in introductory astronomy classes. The magnitude system, Kepler's third law, and the scientific method are the program topics. (CP)

Explains an error analysis procedure using the computer which requires no previous student experience with the computer. (CP)

Explains how to start and operate a science club for grades 4-6 and presents some suggested activities. (BB)
