Presents a series of tried and tested ideas for making the college and high school biology laboratory a place where students can become active investigators. Focuses on infusing investigative laboratories into existing courses, laboratory equipment, student capabilities, instructor time, and student and instructor attitudes toward laboratory…

Outlines a variety of laboratory procedures, classroom materials, and demonstrations including a demonstration of the Markownikoff rule; blue bottle reaction and photosynthesis; a cheaper version of Fehling's solution; chemical formulas for younger students; chemical bonding and periodicity cards; optical activity demonstrations; and six others.…

Outlines a classroom science activity suitable for elementary through adult levels demonstrating that coldwater submergence may cause some people to appear dead when they are not. Includes a description of several activities which exhibit the signs of coldwater camouflage, materials needed, and discussion topics. (DS)

Describes a partnership that linked ninth-grade earth science students with local government agencies and businesses. It facilitated accessing, manipulating, and analyzing digital imagery from satellites and ground-based data-receiving systems. Highlights three projects that involve middle-level students in real-world geological problem solving.…

To support science inquiry in preschools, the Education Development Center in Newton, Massachusetts, developed three teacher's guides to help teachers identify science-rich questions embedded in children's play and use those questions to engage the children in age-appropriate science inquiry. This article follows three Head Start teacher teams as…

Presented are six activities that help to promote critical and creative student thinking. Activities include discrepant events and questioning, divergent thinking, dilemma discussions, and drawing objects from symbols. Activities can be adapted to any science discipline. (KR)

Reviewed are two computer software packages the "Scientific Routines Diskette: Laboratory Automation Using the IBM PC" and "SEQS 3.0 Student Version Simultaneous Equation Solver" for IBM and compatible personal computers. Discussed are hardware, components, level, cost, functions, strengths, and weaknesses. (CW)

Three activities--"Earth's Orbit and the Four Seasons,""Observing Rabbits," and "Solutes, Solvents, and Solutions"--are described. Included in each are background information, a list of materials, key questions, teacher preparation, teacher introduction, procedure, and follow-up activities. (CW)

The use of electronic mail in the science classroom is discussed. Several applications of the use of this technology in the science classroom are described. Optional activities on computer networks are suggested. (CW)

Describes a problem-solving activity integrating a laboratory investigation with a database activity using Appleworks. Presents typical displays of the databases. The objective of the laboratory was to determine the identity of a pure substance by measuring physical properties and searching the database. (Author/YP)

Presented is a science activity designed to help students monitor the pH of rainfall. Materials, procedures and follow-up activities are listed. A list of domestic and foreign sources of information is provided. Topics which relate to acid precipitation are outlined. (CW)

Described are two methods which use microcomputers to illustrate the use of the electrocardiogram and the function of the heart. Included are a simulation and a method of collecting live electrocardiograms. Hardware, software, and the use of these systems are discussed. (CW)

Described is a project in which information about the moral issues surrounding tissue transplants was obtained and videotaped for classroom use. Moral positions and possible educational strategies are discussed. Examples of student statements are presented. (CW)

Discusses some of the contributing factors and chemical reactions involved in the production of acid rain, its effects, and political issues pertaining to who should pay for the clean up. Supplies questions for consideration and discussion. (RT)

Described are three chemistry demonstrations: (1) a simple qualitative technique for taste pattern recognition in structure-activity relationships; (2) a microscale study of gaseous diffusion using bleach, HCl, ammonia, and phenolphthalein; and (3) the rotation of polarized light by stereoisomers of limonene.
