Science is an area of study that can have far reaching implications, influencing and influenced by all aspects of society including politics, ethics, and personal opinions. Science is about more than just the facts, but the process of development and the implications of science knowledge. The main objective of this thesis project is to create…

Much of modern biology has become increasingly chemical in character. Not surprisingly, students often have trouble understanding key ideas in biology because they lack foundational chemistry ideas. AAAS and BSCS are collaborating to develop and study a curriculum unit that supports students' ability to explain a variety of biological processes…

AAAS and BSCS are collaborating to develop and study a curriculum unit that supports students' ability to explain a variety of biological processes such as growth in chemical terms. The unit provides conceptual coherence between chemical processes in nonliving and living systems through the core idea of atom rearrangement and conservation during…

An ecology unit, based upon the interrelations of matter and energy at global, regional, and local levels, was prepared for use with the present secondary school biology syllabus in Rhodesia. The unit was developed after consultation and interviews with educators in Rhodesia, London, and Paris (UNESCO). Rhodesian regions were used to illustrate…

The Australian Science Education Project is producing materials designed for use in grades 7-10 of Australian schools. This is the first trial version of a unit investigating microbial action. One of the student booklets contains instructions for the activities demonstrating food decay which all students are expected to complete. The other student…

The Australian Science Education Project is producing material designed for use in grades 7-10 of Australian schools. This is the first trial version of a unit providing instruction in microscopy. Illustrations of each step in setting up, focusing, preparation of mounts, microscopic measurement, and cleaning and packing the microscope are included…

This is one of a series of units for environmental education developed by the Highline Public Schools. The unit on air pollution is designed for secondary school students in grades 7 through 12. There are five lessons in the unit; since some of the activities can take as long as 90 days, use of the materials needs to be carefully planned. Each…

This unit is a part of a series of materials produced by a project to develop locally applicable class, lab, and field materials in ecology and social studies for Guam junior and senior high school. While the materials were designed for Guam, they can be adapted to other localities. This unit is designed to interest the student in growing plants…

This unit for students in grades 6-12 is designed to provide an introduction to the variables that cause tides. Included are teacher background materials, a possible three-day schedule, master sheets for transparencies, student activity materials, tests, and references to selected films and books. (RH)

This unit is concerned with an overview of physical oceanography - the study of currents, tides, waves, and particle movements. The activities are designed for use by junior high school age students. Included in the unit are activities related to properties of sea water, physical phenomena of the ocean, and physical features of the ocean.…

The purpose of these activities is to offer the secondary school student an opportunity to review what he/she has learned about air by moving quickly through a series of "Do-it-yourself" experiments. Emphasis is placed on the study of the composition of air and relating this information to life in aquatic and marine environments.…

Cytology is the subject that is dealt with in this autoinstructional program. The process to be understood by secondary school students who are taking biology is mitosis. The material is presented to be adequate for achievers at the middle level. Knowledge of the structure of the DNA molecule and of the parts of the cell are considered as…

This unit is part of a series of materials produced by 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, they can be adapted to other localities. This unit is designed to acquaint the students with the geology of…

This unit is part of a series of materials produced by 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 developed for Guam, they can be adapted to other localities. The unit stresses the uniqueness of natural Guam, especially the…
