The Prime Minister's Committee on Natural Science in Education in Great Britain reported in 1918 that "...in many schools more time is spent in laboratory work than the results obtained can justify." Seventy years later this conclusion can often still be drawn. This is particularly a problem in open distance education where laboratory practicals,…

Explores the selection, source, funding, time constraints, and community support involved in developing carefully planned and executed science projects. Lists 21 kinetics experiments noting the instrumentation needed and the original references. (MVL)

Discusses the development of concentration and organizational skills, patience, self-discipline, attention to detail, and appreciation for error analysis through an expanded titration project. Describes the various activities in the extended project and the materials and instructional support needed. Stresses the advantage to students in their…

An experiment is described in which undergraduate students can optimize the relative yield of sec-butylbenzene by varying molar ratio and temperature. (Author/SA)

Describes an advanced NMR project that can be done with a 60-MHz continuous-wave proton spectrometer. Points out the main purposes are to give students experience in second-order NMR analysis, the simplification of spectra by raising the frequency, and the effect of non-hydrogen nuclei on proton resonances. (MVL)

A proliferation of new government regulations and other events in recent years has made it more and more difficult to teach science and engage in science activities. Rapid advances in biotechnology have made it difficult for both students and teachers to stay abreast of current events. These difficulties along with others have turned some teachers…

Science projects which can be used by high school students who have minimal experience with computers or electronics are presented in this book on laboratory interfacing. These laboratory interfacing projects include either the connecting of measuring instruments directly to a computer or using a computer to control external devices. All of the 14…

Animals Alive! is designed to help teachers develop an inquiry-oriented program for studying the animal kingdom in which, whenever possible, live animals are collected locally, studied, observed, and then released completely unharmed back into their natural habitats. By careful selection and modification of the chapter questions, activities, and…

Details construction of an inexpensive electronic auditory device in which the resistance in parallel with the device is inversely proportional to the frequency of sound produced. (CP)

Methods of investigating plant root growth developed for research purposes can be adopted for student use. Investigations of the effect of water table level and of ethylene concentration are described, and techniques of measuring root growth are explained. (Author/ML)

This book provides a short course in the mysteries of seed structure, function, and development. Chapter 1, "Backgrounds, Hints, And Tips For Teachers And Parents," provides a basis for working with the mid-years student. Chapater 2, "Where Do I Start? What Do I Do?" provides procedural tips for science research. Chapter 3,…

Provides abstracts and materials requirements for 20 chromatography projects. Experiments range in complexity; some require synthesis steps, apparatus construction, or special preparation techniques. (MLH)

Success of the Murch Elementary School (Washington, DC) science fair is due to many factors which are applicable to other schools. Suggestions, ideas, and hints are given in this description of the school's program. Projects with an electrocardiogram, water weeds, and preserving ice are also discussed. (DH)

Described are 15 events that take place during a physics olympics at a Michigan high school. These events are planned with the idea of involving the older students in designing and presenting projects to ninth graders, and involving the latter in a day of outdoor participation. (SA)

Describes six different plants which will respond to various artificial stimuli. (SL)
