Attached solar greenhouses are relatively inexpensive and easy to build; they can provide additional heat to homes all winter as well as fresh vegetables and flowers. This bulletin: (1) describes the characteristics of a solar greenhouse; (2) provides a checklist of five items to consider before building a solar greenhouse; (3) describes the four…

Presented are building activities, for elementary school children, using a variety of different materials. Weak materials, such as clay, straws and pins, paper tubes and index cards, are used as examples; structures built with these materials are displayed in photographs and discussed. Problems are suggested from which additional activities can be…

A planetarium, star projector, and projector stand all which can be built for $30 are pictured. Classroom activities involving the materials are described. (CP)

Included are instructions and diagrams for building weather instruments (wind vane, Celsius temperature scale, and anemometer) from simple tools and Tri-Wall, a triple-thick corrugated cardboard. Ordering sources for Tri-Wall are listed. Additional weather instruments that can be constructed are suggested. (CS)

A salt model was developed as a teaching tool to demonstrate the development of caverns and karst topography. Salt slabs are placed in a watertight box to represent fractured limestone. Erosion resulting from water flow can be photographed in time-lapse sequence or demonstrated in the laboratory. (Author/CP)

Describes relief model construction and compass exercises appropriate for the secondary school. (CP)

Using the basic Bagnold design, a relatively inexpensive suction-type wind tunnel can be constructed for laboratory demonstration of sand-grain movement, ripple development, and other eolian processes. Its simple design provides no workshop problems and it can be made for a total cost in materials of approximately $225. (Author/CP)

Equipment and teaching suggestions for science in the middle school are presented. (CP)

Explains the theory and laboratory construction procedures of a positive photoresist. (CP)

This book is one of four books in the Science-by-Design Series created by TERC and funded by the National Science Foundation (NSF). This series presents directed instruction on how to successfully formulate and carry out product design. Students learn and apply concepts in science and technology to design and build a pair of insulated gloves, a…

Describes the use of a faceted geodesic structure in place of the true spherical dome in the construction of an effective and modestly priced planetarium. Indicates that the construction can be undertaken as a student group project. (CC)

The objectives of this construction activity are to develop user-friendly instructional modules that apply concepts of mathematics, science, and technology to solve energy problems; develop an exchange between faculty of technology teacher education and manufacturing technology programs; and serve as a pilot for the development of future modules.…
