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)

Discusses archaeoastronomy, a young science that has become a bridge between the humanities and the physical sciences. Includes a diagram of the multicultural nature of ancient astronomy. (MKR)

Earth's surface is always changing. Much of that change happens because of air, wind, water, and temperature differences. If you have ever observed mud and rocks being carried along by a stream of water after a heavy rain, you have observed the Earth being changed. This month's Science Shorts will investigate how the Earth changes through a…

From 2005-2007, 86 pre-service science teachers surveyed 2,535 middle and high school students in 27 rural, suburban and urban school districts in Northern Illinois on their attitudes about science. The survey consisted of ten questions on a ten-point Likert scale covering interest in science, attitudes about scientists and student confidence in,…
