Presented is a science activities in energy package which includes 12 activities relating to solar energy. Activities are simple, concrete experiments for fourth, fifth, and sixth grades, which illustrate principles and problems relating to energy. Each activity is outlined on a single card which is introduced by a question. A teacher's supplement…

This paper describes five experimental studies which explored the influence of fathers' home caregiving and interactional characteristics on their infant's laboratory behavior. Approximately 300 families with children ranging in age from 6 to 24 months were studied. Each infant's reactions were observed as a function of the manipulation of the…

Length of pauses between quizzes and laboratory assignments in a self-paced psychology-of-adjustment course were examined. Students (n=31) were required to take quizzes from proctors, 15 of which were unit quizzes and five of which were unit review quizzes, and to present five laboratory assignments to the instructor during the course in a…

The goal of this research study was to develop laboratory materials which would present concepts about plants and selected processes of science to undergraduate elementary education students. Three laboratory exercises, each covering a number of concepts dealing with an identified topic, were used. Behavioral objectives were used to combine major…

This compilation of resource units concerns the latest developments in space biology. Some of the topics included are oxygen consumption, temperature, radiation, rhythms, weightlessness, acceleration and vibration stress, toxicity, and sensory and perceptual problems. Many of the topics are interdisciplinary and relate biology, physiology,…

The problems involved when radiation-producing devices of our contemporary technology are used in the teaching of science at the high school and undergraduate college level are discussed. Information is provided on the hazards involved in the use of radiation-producing equipment or radioactive materials in science demonstrations and experiments…

Contents of this symposium include the following papers: "Effect of Maternal Protein Malnutrition on Neonatal Lung Development and Mitochondrial Function," E. J. Hawrylewicz, J. Q. Kissane, W. H. Blair and C. A. Heppner; "Effect of the Level of Nutrition on Rates of Cell Proliferation and of RNA and Protein Syntheses in the Rat," L. M. Roeder;…

A time-sharing FORTRAN program is described. It was created to allow a student to design and perform classical thermodynamic experiments on three models of a working substance. One goal was to develop a simulation which gave the student maximum freedom and responsibility in the design of the experiment and provided only the primary experimental…

THIS RESEARCH CONCERNING CONCEPTUAL BEHAVIOR INVESTIGATED BOTH THE DEVELOPMENTAL ASPECTS OF CONCEPTUAL BEHAVIOR IN A CONTROLLED LABORATORY SITUATION AND THE RELATIONSHIP OF CONCEPT LEARNING IN THIS LABORATORY SETTING TO ACHIEVEMENT IN CURRICULAR AREAS OF JUNIOR HIGH SCHOOL. THE GENERAL PLAN FOR THIS STUDY INVOLVED STRATIFIED RANDOM SELECTION AND…

This vocational physics individualized student instructional module on jacks (simple machines used to lift heavy objects) contains student prerequisites and objectives, an introduction, and sections on the ratchet bumper jack, the hydraulic jack, the screw jack, and load limitations. Designed with a laboratory orientation, each section consists of…

Presents task analysis of the laboratory inquiries of the BSCS Yellow Version. Three important deficiencies are identified: (1) Students do not identify and formulate problems; (2) Students get little chance to conduct investigations; and (3) Post-laboratory discussions are not indicated. (MA)

Presents an analytical or inorganic chemistry laboratory experiment in preparing nickel macrocyclic complex. (SL)

Discussion of laboratory experiment simulation in science and engineering education focuses on the need for authoring systems that can be used to create simulations. An editor for a simulator model containing variables and mathematical equations is presented, and screen displays and data analysis are discussed. (LRW)

Presents investigations to explore the substrate specificity, pH, concentration, and temperature relations of an enzyme with only inexpensive commercial rennet and basic laboratory equipment. Describes how the activities were carried out with a group of 15-year-old students. (CW)

Describes a laboratory experiment to determine the rate law for a substitution reaction of a transition metal. Derives the corresponding rate law from the accepted mechanism for the reaction using the steady state approximation and determines the conditions under which the two agree. (CW)
