Presented are activities for students in grades 3-6 which use assorted breads and spreads to represent layers of the earth's crust. It is suggested that in addition to providing good nutrition, this method has helped the children use the processes of science to deduce some basic principles of geology. (KC)

Presents results of research designed to assess and predict the storm-related hazards of living on the coast. Findings suggest that certain sections of coastline are more vulnerable than others to storm damage. (WB)

Briefly discusses recent developments in worldwide production of industrial chemicals. (MLH)

Reports statistics on the type and amount of geologic mapping in the U.S. during 1976. (MLH)

Discusses discoveries made during 1976 in various areas of invertebrate paleontology. (MLH)

Describes discoveries made in 1976 in areas of vertebrate paleontology, including research indicating that dinosaurs were warm-blooded. (MLH)

Describes common aspects of caves, their development, geology, animals that live in caves, and evidence of human culture left on the walls. (YDS)

Presents a dramatization of a fictitious debate about the age of the earth that takes place at the Royal Institution, London, England, in the year 1872 among Sir William Thomson, T.H. Huxley, Sir Charles Lyell, and Hermann von Helmholtz. (Contains 17 references.) (Author/YDS)

Describes how the Hubble Space Telescope works and how scientists repaired the spherical aberration that caused a reduction in image quality. (ZWH)

An introduction to the science of speleology is presented. Discussed is why people explore caves--for the physical challenge, the thrill of discovery, and the joy of viewing their beauty. Cave conservation, cave biology, caving safety, and caving equipment are topics of discussion. A reading list on caves is included. (KR)

A novel theory about Earth's ancient history is presented. It is proposed that North America and Antarctica once lay side by side for perhaps as long as a billion years. The importance of these continental connections to geology and other disciplines is discussed. (KR)

Presents information on the planet Mercury and points out how little is known about this planet which is much closer than Pluto. Features a list of visible planets and moon phases. (YDS)
