The stated purpose of this resource guide is to entice teachers to explore ecological aspects of coastal awareness. Discussions describe different characteristics of the coast such as: (1) waves, currents, and tides; (2) sandy beaches; (3) rocky shores; (4) estuaries; and (5) marshes. These discussions present some of the physical processes that…

THE PURPOSE OF THIS NATURAL AND PHYSICAL SCIENCE COURSE IS TO INSTILL IN THE PUPILS AN UNDERSTANDING OF THE PURPOSES AND METHODS OF SCIENCE RATHER THAN TO IMPART A CERTAIN BODY OF FACTS. EMPHASIS IS PLACED UPON CLASSROOM DEMONSTRATION AND EXPERIMENTATION SO THAT THE PUPIL WILL LEARN TO THINK CRITICALLY AND TO DEVELOP A QUESTIONING MIND. CONTINUITY…

THE AREAS OF STUDY ARE--LIVING THINGS, OUR GROWING BODIES, AIR, WATER, AND WEATHER, THE EARTH AND ITS COMPOSITION, THE SOLAR SYSTEM AND BEYOND, AND MATTER AND ENERGY. THOUGH THESE ARE DIVISIONS FOR PURPOSES OF CLARITY, THE TEACHER SHOULD CONTINUALLY POINT OUT HOW THEY OVERLAP. EACH SECTION HAS A SIMILAR FORMAT CONSISTING OF--AN EXPLANATION OF THE…

This guide is designed to assist teachers in involving students in individual or small group laboratory investigative experiences in the life sciences. Each of the 22 experiments contains a prelab and postlab section for teachers and a detailed procedures section for students. (Author/CO)

This unit attempts to interrelate the traditional biological science studies such as food webs, population changes and ecological succession to form a coherent picture of our world today, the factors that created it and the forces that continue to change it. Designed for use in the secondary schools, it is built around nine films and has seven…

This newsletter reviews declines in achievement test scores. American College Testing (ACT) program, Scholastic Aptitude Test (SAT), and National Assessment results are reviewed by geographic regions, age groups, sex, race, community type, and order of birth. Results in subject matter areas for 1965-66 and 1975-76 are also reviewed. Conclusions…

This unit is a part of a series of materials produced in a project to develop locally applicable class, lab, and field materials in ecology and social studies for Guam junior and senior high schools. While the materials were designed for Guam, many of the activities can be adapted to other localities. This unit covers ecological factors involving…

Included are diagrams of 12 common plants with descriptions of their seed distribution mechanisms. (SL)

This curriculum supplement aims to bring cutting-edge medical science and basic research discoveries from the laboratories of the National Institutes of Health (NIH) into classrooms. The supplement was designed to complement existing life science curricula at both the state and local levels and to be consistent with the National Science Education…
