The purpose of the present study was to explore how often teachers of young children teach science concepts in kindergarten and examine the factors that influence the frequency of science teaching in early years. A theoretical model of the determinants of the frequency of science teaching in kindergarten was developed and tested using a…

Describes a laboratory exercise using relief models, aerial photographs, topographic maps, and cone studies to determine depth and thickness of a concealed mineralized zone. (MA)

Lists materials and procedures for constructing a model that demonstrates certain aspects of the Coriolis effect. Materials include an electric drill motor, voltage control, toy dart gun and darts, wood blocks of varying dimensions. Includes description of an experiment illustrating relationship between speed of rotation and amount of apparent…

Describes how 30-gram balloons can be used to obtain cloud heights and determine winds aloft. Plans for constructing a workable theodolite inexpensively from common materials are also included. (HM)

Describes ways of projecting stereoscopic images of geologic environments for students with difficulty reasoning in three-dimensions. The photographic procedures needed to produce stereo slides are included. (MA)

This publication provides twelve model spacecraft construction plans for use by secondary school teachers in industrial arts classes. These models were adopted and developed from plans supplied by the National Aeronautics and Space Administration and are representative selections from the many spacecraft used in space exploration programs. Some…

Describes the five-step procedure in the construction of a landform model for the teaching of weathering and erosion on different geographical profiles. (GS)

Materials needed and instructions for constructing a model (groundwater terrarium) to examine the water cycle and its effects are provided. Suggested activities and demonstrations are also provided. (SK)

Describes a simulation drilling core activity involving the use of a physical model from which students gather data and solve a three-point problem to determine the strike and dip of a buried stratum. Includes descriptions of model making, data plots, and additional problems involving strike and dip. (DS)

Provides instructions for the construction of a paper mache classroom planetarium and suggests several student activities using this planetarium model. Lists reasons why students have difficulties in transferring classroom instruction in astronomy to the night sky. (DS)

Two programs are described for teaching earth science and introductory chemistry to secondary students with learning disabilities. Development of the two models involved curriculum revision to engage students in higher order thinking, teaching fewer topics in more depth, and design of materials to provide an integrated, problem-solving basis for…

Sedimentary patterns and hydraulic effects can be studies in model streams which are not to scale. The "Western River" is such a model which is being used effectively at Western Carolina College. Construction of the model, student exercises, and observations made when using the model are discussed. (Author/JN)

The individualized learning model, discussed in this article, uses an efficient feedback mechanism which incorporates an innovative student evaluation program and a unique system of classroom management. The design provides a model for monitoring student progress. (Author/SA)

Activities designed to teach children about solar distance and size are presented. These include a classroom-sized model, an outdoor model, a read-aloud activity, and follow-up activities. Available resource materials in print and on film are listed. (CW)
