Provides: (1) background information on features of the night sky and on how to observe them; (2) five activities; and (3) three ready-to-copy student materials. Activities include objectives(s), recommended age level(s), subject area(s), list of materials needed, and procedures. (JN)

Provides primary grade level science activities that focus on insects, tracks and trails, water, and flight. For each topic, six major ideas plus related activities and suggestions about resources are given. (RH)

Describes a laboratory study in which students evaluate, in ecological terms, different landscapes representing ecosystems under varying degrees of human domination. Also discusses the context within which the study is arranged. (JN)

Describes the natural history of the leopard frog and factors which make it appropriate for short-term study in the classroom. Information on the frog's habits, life cycle, housing, care, and health is included. (DH)

Six secondary school teachers describe their most successful earth science investigations. They include various outdoor field activities, road-map reading skills, student-prepared and conducted investigations, and use of several materials for studying volcanoes. (JN)

Five activities on the concept of evaporation as a cooling process is presented. Activities include discovering which hand, the wet one or dry one, is cooler; reviving a wilted plant; measuring surface area of leaves; collecting water vapor from leaves; and finding out the cooling effect of trees. (ERB)

Presents a class exercise designed to find out how well students understand the nature and consequences of the mass action law and Le Chatelier's principle as applied to chemical equilibria. The exercise relates to a practical situation and provides simple relations for maximizing equilibrium quantities not found in standard textbooks. (JN)

A simple device that aids in plotting poles to planes on structural equal-area diagrams (pi diagrams) is described. It is used in conjunction with a standard equal area Schmidt net to assist students in understanding principles of plotting pi diagrams and for rapid plotting of large amounts of data. (BC)

Erwin Raisz's Landform Map of the United States, a popular teaching aid in geology and geography courses, is available as a jigsaw puzzle. Indicates that puzzle assembly represents a unique way to expose students to the physiographic features of the map without the need for written exercise material. (BC)

In most astronomy courses, descriptions of stars and constellations reveal the western European origins of the astronomers who named them. However, it is suggested that a study of non-western views be incorporated into astronomy curricula. Descriptions of various stars and constellations from different cultures and instructional strategies are…

Describes an approach to the study of entomology directed at people with no special knowledge of insects. The aim of this approach is to reveal some biological principles by studying insects from an ecological point of view. (GS)

Describes experiments involving variations on the electroscope, an electrostatic toy, a stationary wave machine, a spark counter, a carbon microphone, curvilinear expansion, soap films, a barber's pole, and a simple pendulum. (GS)

This book presents science activities developed by teachers for children ages 3-6 years old. The activities aim to develop science skills including communication, observation, estimation, measurement, cause and effect, investigation, and evaluation in children by using their curiosity as a staring point. Activities include age suggestions, address…

This special edition of the National Oceanic and Atmospheric Administration's (NOAA) State of the Coast Project is an interactive educational CD-ROM designed for the general public. Some of the uses, functions, and ways of protecting our coastal and marine environments are explored. High schools will find it a useful complement to natural sciences…

This family activity book features information on the background and filming of five stories. "Pharaoh's Obelisk" questions how ancient Egyptians transported and raised stone obelisks. "Roman Bath" studies how Romans built bathhouses and attempts to build a working Roman bath. "China Bridge" investigates the structure…
