Chromatography is a process by which mixtures can be separated or substances can be purified. Biological and chemical laboratories use many different types of chromatographic processes. For example, the pharmaceutical industry uses chromatographic techniques to purify drugs, medical labs use them to identify blood components such as cholesterol,…

This publication is a teacher participant handbook for an inservice minicourse in developing children's oral language skills, developed by the Far West Laboratory for Educational Research and Development. Four critical teachinq behaviors are stressed: (1) expand the complexity, flexibility, and preciseness of language and thought; (2) model new…

This monograph consists of a text, a guide to the experiments for students, and a guide to the experiments for instructors. The text is intended to provide continuity to relate the experiments to one another and to provide some mathematical basis for analysis of the various phenomena observed. Only the five experiments performed in the student…

This manual provides numerous experiments for college-level microbiology students illustrating the basic principles in phage, tissue culture, and animal virology. (CS)

This manual contains instructions for laboratory exercises using marine organisms. For each exercise a problem is defined, materials are listed, possible ways to solve the problem are suggested, questions are asked to guide the student in interpreting data, and further reading is suggested. The exercises deal with the measurement of oxygen…

The annotated illustrations of biological specimens useful for illustrating the "tropical" topics dealt with in African secondary school biology courses are designed to serve a two-fold purpose. The diagrams are intended to show the pupil the structures he should be looking for in his laboratory work, with the textual material being an…

The course presented in these two textbooks is an experimental integrated science course that is closely based upon the syllabus prepared by the Working Party on Secondary School Science (SE 015 432). The course, intended for all students in the first two years of Scottish secondary schools (grades eight and nine, approximately), interweaves…

Examines the treatment of errors and significant figures in physics manuals as part of an evaluation of these instructional materials. Comments on specific materials reviewed are provided. (JN)

The literature concerning laboratory notebooks is reviewed. A procedure is described for administering laboratory notebooks. Outlined is an indexing system which provides a method for retrieving information by laboratory notebook number, by name, and by general subjects. The indexing scheme is estimated to be adequate for collections up to 5,000…

This laboratory training manual on laser communications and fiber optics may be used in a general technology-communications course for ninth graders. Upon completion of this exercise, students achieve the following goals: match concepts with laser communication system parts; explain advantages of fiber optic cable over conventional copper wire;…

Provided are 45 experiments in chemistry which have been used successfully by students in secondary school chemistry classrooms. Additional investigations directed at further inquiry on the part of the student are included. The experiments are directed at the development of science process skills and many of the concepts and generalizations which…

Included are two of the eight units of the Intermediate Science Curriculum Study materials designed for grade nine students. These are "Why you're you" (genetics), and "Crusty problems" (earth science). The first unit includes basic chapters and "excursions" which extend some of the ideas developed in the basic…

Included is the first half of the chapters and excursions of the Intermediate Science Curriculum Study materials designed for grade eight students. Although I.S.C.S. is an integrated science course, most of the concepts developed in this volume relate to chemistry. Introductory notes to the student explain how the book is to be used. Each chapter…
