Describes how to construct a simple device that students can use to estimate how high their kites are flying, as well as the heights of other objects. (TW)

Contains 10 teaching tips about such topics/ideas as low-impact nature trails, sand, overhead transparency use, the cause of "trash," rainbows, the solar system, controlling variables, time keeping, science discovery centers, and animal characteristics. (TW)

Describes some art activities for early childhood that also teach about science. Expresses concern that young children operating in a three-dimensional world are often expected to translate their world onto a flat sheet of paper. (TW)

Presents several strategies to teach the reactivity of metal elements. Stresses the safety aspects of these demonstrations using an overhead projector and a plexiglass safety shield. Lists some of the essential learnings desired in these activities. Includes a chart of the activity series of metals. (CW)

Describes a classroom experiment designed to teach students the fundamentals underlying the normal coordinate analysis procedure of a polyatomic molecule. Uses a reverse procedure from traditional experiments of this type by providing the values for the force field and working backwards. (TW)

Describes some of the characteristics of various reptiles. Contains teaching activities including making reptile number books and identification keys, flip-ups about cobras, puzzles involving graphing, and group presentations. Includes reproducible handouts to be used with some of the activities. (TW)

Describes how a ladybug can be used to teach entomology, natural selection, comparative anatomy, food chains and symbiotic relationships. Focuses on a picturebook entitled "The Grouchy Ladybug" (Eric Carle). Discusses enrichment activities in science, language, social studies, art, and music. (CW)

Contains four articles about various aspects of science education. Addresses a graded assessment scheme in Great Britain, factors affecting school science achievement in Nigeria, the need to address differentiation in science curricula, and the encouragement of developing science hypothesis in elementary schools. (TW)

Describes an experiment involving data acquisition by a computer, digital signal transmission from the computer to a digital logic circuit and signal interpretation by this circuit. The system is being used at the Illinois Institute of Technology. Discusses the fundamental concepts involved. Demonstrates the alarm experiment as it is used in…

Describes a successful two-week summer program for children in grades four through six of above average ability. Discusses the purposes and syllabus for the program. Provides a summary of a typical daily agenda and discusses events that occurred during the two-week period. (CW)

Describes a laboratory experiment to determine the rate law for a substitution reaction of a transition metal. Derives the corresponding rate law from the accepted mechanism for the reaction using the steady state approximation and determines the conditions under which the two agree. (CW)

Illustrates the scope of experimental investigations for biochemistry education in high school biology and chemistry courses. Gives a brief overview of biochemistry experiments with proteins, enzymes, carbohydrates, lipids, nucleic acids, vitamins, metabolism, electron transport, and photosynthesis including materials, procedures, and outcomes.…

Presents descriptive information about carnivores, including a definition and the characteristics. Contains instructions for teaching activities along with reproducible worksheets and handouts. (TW)

Presents information on some of the unusual mammal groups, such as platypuses, kangaroos, anteaters, and armadillos. Characteristics of these animals are given and teaching activities are described, including "Oddball Options,""Pocket Pals," and "Fact and Fancy." A reproducible handout for "Oddball Options" is included. (TW)

Explains how computer and game port interfacing reduces the time required for data collection and organization and also stimulates student interest in science laboratory exercises. Illustrates this approach through a description of a population-variation lab. Includes diagrams for the construction of the interface box. (ML)
