Provides plans for simple, inexpensive teaching aids and equipment for visually impaired children. Details for building null detectors, electronic thermometers, and calorimeters are included. (DDR)

Discusses the accomplishments of a model program characterized by an intense training program, an active network among teachers, and a learning-friendly laboratory classroom. (DDR)

Describes a simple halogenation experiment that can be performed quickly in an open vessel at room temperature with visible light that is appropriate for the beginning weeks of an introductory organic chemistry course. (WRM)

Provides a protocol for examining the mechanisms of animal thermoregulation in a straightforward but more sophisticated manner than using a thermal gradient. Describes a methodology for conducting operant conditioning to examine thermal set points for ectothermic animals. Contains 20 references. (WRM)

Argues for the use of instruments in introductory level chemistry and presents multiple perspectives on the issue. Reasons for employing instrumentation include the ability of introductory classes to reach a large number of students, the need to model situations in which scientists work, and student expectations regarding the use of technology.…

Describes an ammeter that can be built for less than a dollar with commonly available parts to be used in circuits with 3-volt light bulbs. (WRM)

Describes the development, preparation, and use of a medium that can select against a wide variety of Gram-negative bacteria while still allowing growth and differentiation of a wide range of Gram-positives. (WRM)

Describes the construction and use of an inexpensive, portable photometer designed specifically for estimating population sizes in yeast cultures. Suggests activities for use with the photometer. (WRM)

The use of complex instruments for chemical analysis is becoming increasingly important. Unfortunately, because of school budgetary constraints, many students are not exposed to these methods until they reach the college level. When students do have access to sophisticated instruments, they often view them as black boxes, with little or no…

In this article, the author talks about an inquiry-based activity involving yeast, wherein students learned about cell size. The activity allows students to employ math connections and to learn experimental techniques while practicing microscope skills. The activity can be adapted for students at all levels of biology. The author presents details…

An important part of the science classroom involves teaching students how to safely use tools, techniques, and procedures. As emphasized in the National Science Education Standards, "safety is a fundamental concern in all experiential science" and teachers must "teach students how to engage safely in investigations inside and outside the…

Laboratory demonstration, as well as biochemistry lecture, has been used to complement explanation of biochemical processes. The laboratory demonstration is very useful in teaching biochemistry to students who lack background in biology. The experimental model of fibrinolysis described here presents a complex biological reaction in simplified…

A new, integrated laboratory curriculum was recently developed at the U.S. Naval Academy in response to the 1999 ACS Committee on Professional Training guidelines that required inclusion of biochemistry and a stronger emphasis on student research. To meet these ACS requirements and to introduce more student choice in the major, we embarked on a…

This monograph is one in a series of analytical reports presenting findings from the National Science Foundation's 1989-90 National Survey of Academic Research Instruments and Instrumentation Needs. It describes recent national trends in academic research equipment and equipment needs in the physical sciences. It also documents equipment trends in…
