Describes scientific research on an Earthwatch expedition to study Arenal, one of the world's most active volcanoes, in north central Costa Rica. The purpose of the two-week project was to monitor and understand the past and ongoing development of a small, geologically young, highly active stratovolcano in a tropical, high-rainfall environment.…

Demonstrates the magnitude of an extinction event by using a simulation to illustrate the massive nature of the loss of a family and the number of species that perish to achieve that result. (RT)

Provides a format for the identification of fossils when introducing geologic time in the laboratory. Presents an organization of fossils into three major groups based on radial, bilateral, and no apparent symmetry. States that this method reinforces student learning and provides for an orderly approach to fossils. (RT)

Describes activities for secondary earth science and biology classes in collecting, preparing, mounting, and manipulating microfossils. (SL)

Newton's Apple is a PBS family science program that explores basic science through high-energy, hands-on demonstrations. This volume is a collection of the teacher's guides from four seasons of Newton's Apple which were originally broadcast from 1991 through 1994. Each of the four seasons in the volume contains 26 lessons and a combination of…

This folio of test items, contributed by a number of colleges and universities from their course, placement, entrance, or other institutional examinations, was compiled to aid teachers in constructing tests. Only those science courses offered in the first two years of college are represented by the scope of the items. The test items may also serve…
