Currently, the biological sciences' arsenal of information and knowledge is increasing at such a rate that teachers cannot expect or be expected to teach all the "facts" that are known. Instead many are suggesting that teachers should help students to develop an ability to use and apply fundamental concepts in a critical and analytical way. To…

This study guide is designed to help students learn to use science skills to solve biological problems, learn to apply knowledge about biology in their own lives, and learn to communicate with others about biology. The activities in this guide use information related to each chapter in the 1987 BSCS Green Version textbook. Students can use the…

In 1982 the Dade County Public Schools (Florida) began developing test item banks for secondary subject areas, because other testing programs have limited utility for assessing the quality of curriculum, instruction, or learning in specific content areas. In May l984, the approximately 17,000 seventh graders enrolled in Life Science and the…

This curriculum guide lists science topics and concepts, learning outcomes, and sample learning objectives (in three columns) for these secondary school science courses in Alaska: (1) general science (grades 7-12); (2) life science (grades 7-12); (3) physical science (grades 7-12); (4) earth science (grades 8-10); (5) biology (grades 10-12); (6)…

This document provides information about careers in the agricultural sciences, the biological sciences, chemistry, forestry and conservation, geology and geophysics, meteorology, and physics. The information, presented in separate sections for each of these disciplines, includes: (1) nature of the work performed by scientists in the discipline(s);…

GRADES OR AGES: Grades 6-9. SUBJECT MATTER: General science, life science, earth science, and physical science. ORGANIZATION AND PHYSICAL APPEARANCE: The guide is divided into separate sections for each grade. Each section is further subdivided into units. The major portion of each unit is laid out in four columns; column headings are concepts,…

Supplementary resource materials for use in upper level secondary school German classes are presented in this text. Teachers who are seeking new content and are willing to adapt these instructional materials on ecology in Germany will find three self-contained units on: The Plight of the Polar Bear, Polluted Swimming Pools in Germany, and Dead…

The basic elective course in introductory botany is designed for secondary students who probably will not continue study in plant science. The objectives of the course are to help the student 1) identify, compare and differentiate types of plants; 2) identify plant cell structures; 3) distinguish between helpful and harmful plants; 4) predict…

Describes a laboratory activity that is adaptable to several levels of biology students. Discusses methods for obtaining hellgrammites, performing the experiment, and analyzing the data. Includes sample charts and graphs. (CW)

Described is a study designed to introduce students to the behavior of common invertebrate animals, and to use of the chi-square statistical technique. Discusses activities with snails, pill bugs, and mealworms. Provides an abbreviated chi-square table and instructions for performing the experiments and statistical tests. (CW)

Lists and reviews 10 recently published books from Mexico and Spain that can assist Spanish-speaking students in understanding life science, sexuality, computers, and computer programming. Gives age levels and brief descriptions of each book. (CW)

Describes two computer simulation programs, "Nerve Physiology" and "Frog Heart," as practical alternatives to the use of live animals in class experiments. Discusses the potential of computer simulation as a feasible alternative to experiments with animals in the classroom laboratory. (CW)

Presents a model system designed for the electrophysiological investigation of single unit activity in intact anaesthetized animals. Illustrates how information is coded into action potential patterns by sense organs. Uses the ampullary electroreceptor of the brown bullhead catfish as an example. (Author/CW)

Describes a five year research project in plant ecology by successive teams of students. The aim was to identify environmental factors which were determining the distribution of the vegetation on a pitheap. Includes descriptions of vegetation, soil properties, and computer assisted analysis of results. (Author/CW)

Outlines an adaptive framework for the study of plants and their pollinators in which both partners in the ecological relationship are seen as maximizing fitness through efficient use of the other as a resource. Suggests experimental projects to examine the validity of these assumptions giving an evolutionary emphasis. (Author/CW)
