Describes an approach to teaching population genetics and evolution and some of the ways models can be used to enhance understanding of the processes being studied. Discusses the instructional plan, and the use of models including utility programs and analysis with models. Provided are a basic program and sample program outputs. (CW)

Discusses why creation science could be discussed in a high school biology class. Examines the debate that exists between scientific creationists, biblical literalists, and traditional scientists regarding the teaching of creation science in schools. Describes how discussion of this debate could help students understand the nature of science. (CW)

Describes a field trip activity to measure changes in elevation across the dunes of a barrier beach, measure wind velocity along the transect line, and observe the distribution of ground cover in the study area. Discusses equipment, materials, procedures and follow-up activities for each study. (CW)

Describes the development of a topics course offered jointly by the chemistry and biology departments at Macalester College (Minnesota). Outlines the syllabus for the course. Discusses teaching and laboratory methods used. (CW)

Describes the flour beetle, "Tribolium confusum," and its life cycle, habitat, culturing requirements, and some possible uses of this beetle as a classroom animal. Discusses what children could learn from flour beetles. Explains how to get rid of beetles found in foods at home. (CW)

Presents a model, organizational procedures and evaluative findings of a science curriculum development program. Inservice teachers co-operatively developed modular science courses for underachievers, lists of science skills and attitudes, and materials for environmental science, physical science and biological science courses. (ML)

This activity book is part of a series designed to take a concept or idea from the existing school curriculum and develop it in the context of the Great Lakes using teaching approaches and materials appropriate for students in middle and high school. The theme of this book is life in the Great Lakes. Students learn about shorebird adaptations,…

This document presents the revised Arkansas Science Curriculum Framework (1999), which replaces the Science Curriculum Framework of 1994. Three strands--physical science systems, life science systems, and Earth science/space science systems--were identified using an integrated approach to provide guidance in the science curriculum. A glossary and…

This document explains the Arkansas science benchmarks for grades 5-8 which were developed to provide guidance to science teachers. The content standards for three strands--physical science systems, life science systems, and Earth science/space science systems--were identified based on grade levels. (YDS)
