Designed to promote the use of safe, controlled investigations in science classrooms in Texas, this publication describes procedures to help teachers ensure the safety of all students in class and on field trips. Safety in the elementary science classroom and in secondary school science courses is discussed. Included are first-aid procedures,…

This document provides a laboratory manual for use by secondary level students in performing consumer-oriented laboratory experiments. Each experiment includes an introductory question outlining the purpose of the investigation, a detailed discussion, detailed procedures, questions to be answered upon completing the experiment, and information for…

This booklet presents 18 experiments in the chemistry of food, suitable for elementary and secondary school science classes. Experiments deal with an analysis of milk, determinations of the amounts of sulfur dioxide, iron, and fat in foods, and the concentration of vitamin C in fruit juice and iodine in salt. Tests are provided for fats,…

Included are the teacher's manual and the student's manual for the unit "Forces and Motion," one of a series of units for non-academic students developed by the 1970 Senior High School Science Workshop Committee. This unit is designed to give students an understanding of forces and motion. It is designed for students to learn how to: recognize…

The first trial edition of the Australian Science Education Project unit introducing the concepts of electrical charge consists of a student workbook, question booklet and a response sheet, and a booklet containing answers to the questions in the workbook and question booklet. The teacher's guide outlines the unit, lists suggested teaching…

Laboratory experiments are presented in these first three manuals of a six-volume series for use at the 12- to 16-year-old, or British CSE, level. On the subject of food tests, 17 exercises are prepared in connection with Biuret reactions, starch and emulsion tests, Millon's and Benedict's reagents, reagent sensitivity, and calorific values and…

Nuffield Combined Science is a set of tested instructional materials prepared in an "attempt to recapture the unity of outlook and consistency of method which belong to the whole of science and which enable us to make reasoned statements about the world we live in." The student-centered activity-based materials integrate the traditional…

This second trial edition is a revision of ED 049 929. The core portion of the unit, which is intended for students in grades seven or eight of Australian secondary schools, provides suggestions for activities designed to lead to an understanding of the structure, composition (biotic and abiotic), and origin of soils. Keys are provided for the…

This revised trial version of ED 061 083 is a unit of the Australian Science Education Project materials for grades seven through ten in Australian secondary schools. It is intended for students in the concrete operations stage of intellectual development. It provides activities to give students a broad introduction to the concept of energy, which…

Presents a table cross-referencing 12 physics laboratory manuals by topics. Topic areas include measurement and techniques, mechanics, molecular physics, waves and optics, electricity and magnetism, and quantum physics. (JN)

Ten experiments and 27 activities are presented in this handbook. The experiments are related to collisions, energy conservation, speed measurements, thermometry, calorimetry, gas properties, wave motions, and acoustic problems. The activities are concerned with stroboscopic photographs in collision, elastic impact, mass conservation, exchange of…

This revised and expanded version of a similar manual first published in 1969 is designed to acquaint students at both junior and senior levels with some of the problems and effects of air pollution and the practical means of overcoming them. The 38 experiments comprise a group of exercises which can be selected according to the interests of the…

Mental and physical models are treated in the Australian Science Education Project trial unit prepared for students in a transitional stage between concrete and abstract reasoning. Students are introduced to the particle model of matter through a series of core activities, including a combination game using nuts and bolts, culminating in a…

This unit, providing information about human nutrition and energy use, has been prepared for students whose level of thinking is transitional between concrete and formal stages. The unit is based upon an analogy between combustion and respiration and upon the molecular structure of food components. The core portion of the unit presents activities…

Reviews and compares results of content analysis studies of selected high school science laboratory handbooks using the Laboratory Structure and Task Analysis Inventory (LAI). Findings from two biology, two chemistry, and two physics handbooks indicate highly structured investigations where students perform manipulative and observational…
