Student-designed laboratory exercises have become an important part of the physics classes at Piedmont Virginia Community College. Rather than filling in the blanks of a laboratory workbook, students are required to design and carry out weekly experiments which relate to the physics concepts being studied. Using computers, standard laboratory…

This article outlines the development of an urban elementary school gardening project where children learn science and responsibility for the environment. Charts provide a gardening timeline, planting plan for each grade level, instructions for building a grow cart, and indoor experiments that test environmental factors for each grade level. (LZ)

Twelve desk-top experiments and demonstrations which illustrate properties of and facts about gas are presented. Each experiment includes: purpose, materials needed, instructions, and a list of facts and properties that have been observed. Several of the activities also include questions for students and items for discussion. The topics of the…

This article describes a science learning experience in which intermediate grade students launched balloons with attached postcards to study wind currents. More than 200 (of over 900 balloons) were returned, and their analysis supported the students' hypothesis about the direction of wind currents. (DB)

Gives four science lessons for third graders concerning combustion, density, static electricity, and air pressure and surface tension. (RH)

Presents three problems that can be used in classroom to motivate chemical engineering students at the college level. (HM)

Describes a factorial experiment that is used as a laboratory exercise in a research methods course. Uses a Howard-Dolman depth perception apparatus, combining the factors of viewing condition and rod orientation to illustrate the nature of an interaction and the necessity of an additional analysis of simple main effects. (Author/LS)

Describes a computer game used in an introductory experimental psychology class which simulates in a few months the activities of years of effort in a research laboratory. Ideas on developing new computer based simulation games are included. (Author/JJD)

Summarizes the use of field experiments designed to investigate personal space invasion. States that the experiments were designed and conducted by introductory psychology students and complemented by classroom lectures. Reports that the experiments provided an understanding of personal space, personal space invasion, and the implications…

Described is an activity designed to make the concepts of experimentation, independent variables, and dependent variables easy to understand by using observable characteristics of several rods to illustrate these concepts. (DS)

Presents classroom learning activities to help elementary teachers and students learn about and experiment with the sense of taste. One involves tasting an apple while smelling an onion; another involves locating areas of the tongue that respond to salt, sweet, bitter, and sour. (SM)

Gives instructions for simple meteorological instruments that students can make and then use to monitor temperature, humidity, dew point, rainfall, and wind speed. (SJL)

Described is an in-class demonstration of mass reaction time which measures the speed of nerve impulses and the duration of various cognitive processes. A simpler version of the experiment for at-home use is described. (Author/DB)

Presents an idea for insect study with live organisms. The life cycle of the common housefly and the behavior of the adult and larvae are discussed. Activities for young students are given along with information for the teacher on the fly's life history. (SA)

This article reports the adoption of new policies to restrict experiments on animals in the elementary or secondary school classroom. The controversy involving animal welfare groups is discussed as it relates to animal abuse by students. (SA)
