Discusses common as well as uncommon minerals that are attracted to a hand magnet. Included in the discussion are answers to the following questions: (1) What causes this attraction? and (2) How many different minerals respond to a hand magnet? (ZWH)

Presents an activity that demonstrates a crude method of mapping the sea floor and helps students appreciate some basic considerations that scientists face in working with a project of this type. Demonstrates the logistics of teamwork and the effects of time and cost limitations on science projects. (JRH)

Activities in which students build their own simulations of fossils, using seashells, chicken bones, toy dinosaurs, or leaves as models and plaster of paris, sand, mud, clay, or a mixture of gravel and clay as a matrix are presented. Curriculum extensions are included. (KR)

Describes how bottle collecting can be used for serious studies. The emphasis in the activity is on systematic exploration for bottles and identifying the period when the bottles were used. Bottles, one hundred or more years old, can be found in many junk yards. (PS)

A description of a field experience to demonstrate some basic principles concerning the geologic transport of beach sands. (Author/CP)

Describes an activity for grade 7-9 students previously introduced to topographic maps and profile lines. Two profiles of equal scale are used to help students appreciate the tremendous size of mid-ocean rift valleys. Procedures and examples of completed profiles are provided. (JN)

Describes classroom science demonstrations and experiments that simulate the process of fossil formation. Lists materials, procedures and suggestions for successful activities. Includes ten student activities (coral fossils, leaf fossils, leaf scars, carbonization, etc.). Describes a fossil game in which students work in pairs. (CS)

Presents experiments with polarized light for grades 8-12 which can produce colorful effects with a minimum of equipment and can illustrate many principles of physics, chemistry, and geology. (MKR)
