Describes the procedures used to demonstrate transpiration with the common sunflower. Discusses the results expected from such an activity. Provided is a sample data sheet. (CW)

SCIENS is a Middlebury College (Vermont) program designed to excite minority student interest in the natural sciences and to provide students with training and research experiences. The program, encompassing three summers, involves core instruction for high-potential 11th-grade students, summer research in college laboratories, and internships in…

Explains gyroscopic motions to college freshman or high school seniors who have learned about centripetal acceleration and the transformations of a couple. Contains several figures showing the direction of forces and motion. (YP)

Demonstrates several objects rolling down a slope to explain the energy transition among potential energy, translational kinetic energy, and rotational kinetic energy. Contains a problem from Galileo's rolling ball experiment. (YP)

Describes a laboratory experiment designed for use in a freshman chemistry course. Considers the use of a set of known "training reactions" with a "training set" of solutions. (CW)

Explains how peer writing tutors not only help their fellow students, but can also learn a great deal themselves about grammar and mechanics, information processing, marking papers, audience awareness, and problem-solving strategies. (ARH)

Describes a simple redox reaction that occurs between potassium permanganate and oxalic acid that can be used to prepare an interesting disappearing ink for demonstrating kinetics for introductory chemistry. Discusses laboratory procedures and factors that influence disappearance times. (CW)

This description of microcomputer-based laboratories (MBL) for science focuses on experiments with a motion detector by non-science majors at Tufts University. Exercises had been used previously with sixth grade middle school students, indicting the effectiveness of MBL for students with a wide range of abilities. (Author/LRW)

Addresses the history and philosophy of accident prevention in chemistry laboratories. Presents the results of a statewide survey done in Colorado designed to investigate the etiology of academic chemistry laboratory accidents in institutions of higher education. Patterns of accident characteristics identified by the student are discussed. (TW)

Describes an experiment designed to introduce biochemistry students to the specificity of an analytical method which uses an enzyme to quantitate its substrate. Includes the use of toxicity charts together with the concept of the biological half-life of a drug. (TW)

Describes applications of speech processing equipment that can communicate clearly with students about the patterns of sound and can teach students to monitor their own progress in second language acquisition. Discusses equipment being used at West Chester University (Pennsylvania) for learning pronunciation and stress in several different…

Librarians should adopt a teaching role to instruct users in microcomputer literacy, as microcomputer laboratories and software collections are increasingly a part of academic libraries. University of Wisconsin-Parkside has provided microcomputer orientation workshops and faculty seminars in their microcomputer lab for students, faculty, and…

Describes the rationale for using computer-assisted videodisc lessons to enhance introductory chemistry courses at University of Illinois, and presents sample lessons to illustrate what students see and do as they proceed through the lessons. Lesson construction and use are reviewed. (MBR)

Describes several laboratory experiments that are adaptations of clinical tests for certain genetic diseases in babies. Information and procedures are provided for tests for phenylketonuria (PKU), galactosemia, tyrosinemia, cystinuria, and mucopolysaccharidosis. Discusses the effects of each disease on the infants' development. (TW)

Describes an experiment developed at Brooklyn College (New York) in which the preparation and ammonia analysis of an amminenickel(II) chloride is extended to include a spectrophotometric analysis for nickel. Discusses the materials needed and the procedure for the experiment which takes nine hours of laboratory work. (TW)
