Discusses ways for teachers to help students understand how to ask questions appropriate for scientific inquiry. (WRM)

Presents a series of experiments that can be used to demonstrate how aspirin can be synthesized and characterized, how the hydrolysis of aspirin can be used as an introduction to kinetics, and how coordination chemistry (chelation) can be introduced by preparing and characterizing the copper complexes of aspirin and salicylic acid. (Contains over…

Presents instructions for carrying out polymerase chain reactions with a bit of inexpensive equipment. (WRM)

Describes some experiments that can be performed at home to illustrate what makes popcorn "pop". (WRM)

A biotechnologist-turned-teacher introduces a series of laboratory modules incorporating concepts from microbiology, cellular biology, molecular biology, biochemistry, and evolution. The Amylase Project aims to distill the biotechnology process into a few short steps using amylase, the easiest enzyme to detect of those commonly produced by…

Offers free software for timing experiments, instructions for making a timing interface and a variety of switch sensors for any IBM-compatible computer, and suggestions for experiments. (AIM)

Describes how computer simulations can enhance students' learning of physiology. Discusses how computer models enhance experimentation; using computer modeling in high school science; three steps in students' writing of a simulation; and the value of simulations. Lists six software vendors who offer packages on the PC or Macintosh platforms. (AEF)

Discusses BioProjects, a new technique for helping students understand the scientific method, in which students formulate a hypothesis, test it, and present the project to the class. States that through biological, quantitative investigations conducted outside of the classroom, BioProjects helps students develop investigative as well as oral and…

Emphasizes the importance of using examples from the student's environment to aid in teaching science process skills. The author uses diagrams to aid in discussing the various uses of goldenrod (Solidago sp) galls in the classroom. (ZWH)

Describes the "Teachers + Occidental = Partnerships in Science" (TOPS) program whose goal is to improve high school biology and chemistry students' laboratory instruction by enhancing their teachers' knowledge and classroom application of modern instruments, technology, and experiments. Includes 13 classroom-tested experiments that employ a…

Addresses the difficulty that teaching assistants and new faculty members may experience in finding a convenient outline of the task of preparing an experiment for undergraduates. Explains all phases of developing a laboratory exercise and includes a list of things to consider for each phase. (DDR)

Describes a computerized English-auction experiment that helps students to understand marginal cost and its interrelationships with supply and the efficiency of competitive markets. Explains that the English auction is in a market where there are many sellers (students) and one buyer (computer). States that this exercise offers a good introduction…

Tests a multifaceted curriculum for use in introductory earth science classes from the secondary school to the introductory undergraduate level. Simulates the greenhouse effect with two fish tanks, heat lamps, and thermometers. Uses a hands-on science approach to develop a deeper understanding of the climate system among students. (Contains 28…

Describes unexpected experiences with student laboratory activities. Makes recommendations for addressing two types of lab disasters: (1) when lab preparations fail prior to the beginning of lab; and (2) when students produce unexpected results with the proper use of materials. (Contains 11 references.) (WRM)

Describes a method for measuring the earth's magnetic field using an empty toilet paper tube, copper wire, clear tape, a battery, a linear variable resistor, a small compass, cardboard, a protractor, and an ammeter. (WRM)
