Offers suggestions for teaching some aspects of water economy in plants. These include diffusion/osmosis, water transport, the part played by turgor in structural support, and its implications for plant organs or whole plants. Several practical demonstrations/experiments are also described. (JN)

In a poster session, students explain an experiment with the help of a poster that outlines the experimental procedures followed. Suggestions for preparing posters and conducting poster sessions are provided. A sample poster on the strength of electromagnets is also provided. (JN)

Describes a field trip designed to give students opportunities to experience relevant data leading to concepts in biogeography. Suggests that teachers (including college instructors) adapt the areas studied and procedures used to their own locations. Includes a suggested field trip handout. (JN)

An apparatus simulating residential thermostat control was developed to test claim that lowering house thermostats saves energy and to give students a better understanding of how thermostats work. The apparatus (includes diagram of same) and student activity are described. (JN)

Materials needed and instructions for constructing a model (groundwater terrarium) to examine the water cycle and its effects are provided. Suggested activities and demonstrations are also provided. (SK)

Suggested activities for data collection and manipulation in the middle/junior high school are provided. The activities also help students to learn other process skills such as constructing graphs, describing relationships between variables, and analyzing their investigations. (JN)

Suggestions are provided for teaching a unit on bees to first-grade students. In addition to science content, students learn valuable citizenship and academic skills while engaged in such activities as honey-tasting, visiting an apiary (bee farm), and writing poetry. (Author/JN)

Describes an oceanography learning center for elementary/middle school students, focusing on use of games (review jeopardy), instructional tapes, flash cards, activity felt boards, picture puzzles, reading materials, science displays, and experiment stations. (JN)

Suggests thinking of "tracks" as clues and using them as the focus of outdoor activities in the urban environment. Provides 24 examples of possible track activities, including: seeds on the ground (track of a nearby tree), litter (track of a litterbug), and peeling paint (track of weathering forces). (JN)

Describes classroom use of a computer program originally published in Creative Computing magazine. "The Nuclear Power Plant" (runs on Apple II with 48K memory) simulates the operating of a nuclear generating station, requiring students to make decisions as they assume the task of managing the plant. (JN)

Operationalizes a psychological theory of productivity with data from a large sample of 13-year-old students administered eight items concerning voluntary science activities in the National Assessment of Educational Progress (NAEP). Discusses validity of model of the productivity theory and usefulness of secondary analyses of NAEP data. (Author/JN)

Several activities related to color are discussed. These include placing different colors on a disk which, while spinning, appears to be white. Also discusses complementary and primary colors. (JN)

Describes problem-solving activities in the Unified Sciences and Mathematics for Elementary Schools (USMES) and Elementary Science Study (ESS) programs. Indicates that these curricula serve as excellent sources of activities to develop and improve their students' problem-solving skills. (Author/JN)

Suggests using African-clawed frogs (Xenopus laevis) for conditioning (behavior) experiments. Other experiments using these easy-to-care-for frogs are outlined. (JN)

Provides suggestions for conducting field trips at the local school site. Points of interest might include building materials, evidence of chemical/physical weathering, variations in soil type, changes in elevation on school ground, and others. Three simple field trips are described. (JN)
