Presents lists of materials needed and procedures to build a collection of dinosaurs using different sized boxes, build life-sized dinosaur bones using paper-mache and chicken wire, make paper dinosaur stickers, and make dinosaur pop-up cards. These arts/crafts activities can be used to complement activities in science and other subjects. (JN)

Teachers (N=146) using Science Curriculum Improvement Study were surveyed for their views on teaching disabled students in regular science programs. Results show that teachers feel positively about teaching disabled students (but also feel inadequate with this responsibility). Advantages and disadvantages of mainstreaming in elementary science are…

Discusses development and use of an aquatic studies conceptual scheme which has been used in the Project COAST (Coastal, Oceanic and Aquatic Studies) at the University of Delaware. Sample concepts and results from field testing of the curriculum are included. (DH)

Investigated effects of varied wait-time durations and cognitive questioning levels on student achievement. Analyses of achievement results (using 30 preservice elementary teachers and 129 students) indicated significant differences attributable to teacher wait-time and cognitive questioning level. (JN)

This study describes strategies fifth- and sixth-grade children used to solve the problem of determining how to control a "vehicle" they "drove" by pressing particular keys on a computer. The problem involves identifying or discovering a set of cause-effect relationships. (Author/JN)

Presents an overview of a long-term unit centering on observations of biological change. Explains the purpose, procedures, and activities of long-term projects as: watching a plot of land; seeing how a baby grows, and witnessing kitten birth and growth. Suggests additional activities which address the concept of continuity. (ML)

Provides background information on the earthworm. Reviews basic anatomical, behavioral, and reproductive facts. Offers suggestions for procuring, maintaining, and breeding colonies for classroom use. (ML)

Discusses strategies and activities used to introduce chemistry topics to kindergarten children. These topics include atoms, acids and bases, and molecules and gases. (JN)

Discusses the behavior, housing, care, diet, and feeding of painted turtles. Also suggests several classroom activities and provides guidelines related to long-term captivity and human disease prevention. (DH)

Discusses types of solar eclipses and the frequency of their occurrence. Emphasis is placed on the May 30, 1984 solar eclipse. Ideas for building a pinhole camera to view the eclipse, to determine if the sun is changing size, and to report scientific findings are provided. (BC)
