This booklet introduces high school and junior high school students to the major groups of aquatic insects and to population sampling techniques. Chapter 1 consists of a short field guide which can be used to identify five separate orders of aquatic insects: odonata (dragonflies and damselflies); ephemeroptera (mayflies); diptera (true flies);…

This curriculum guide to the physical sciences was prepared for use in high schools in Duval County, Jacksonville, Florida. Courses covered for grades 10-12 are chemistry, advanced chemistry, physical science, physics, advanced physics, science survey/physical, and science research. For each course, the following elements are included: notes to…

Activities in the life and physical sciences are provided (in separate sections) for preschool and elementary school students. Life science activities include those related to plants, soil, habitats, fossils, animals, life cycles, food chains, nutrition, and other biologically-oriented topics. Physical science activities include those related to…

Slope Stability is one in a series of single-topic problem modules intended for use in undergraduate and earth science courses. The module, also appropriate for use in undergraduate civil engineering and engineering geology courses, is a self-standing introduction to studies of slope stability. It has been designed to supplement standard…

This guide, the third in a series of three, provides the intermediate science student and teacher an opportunity to review selected science concepts and processes through activities which emphasize the applicability of scientific knowledge in the professional world. The three components in this guide deal with (1) the scientific principles of…

Four classroom activities are included in this 8-10 period unit suitable for high school chemistry and physics classes. The first activity is a reading (12th-grade readability level determined by the Fry procedure) which explains electricity conversion, transportation, and efficiency ratings. The second and third activities are electrical energy…

Some research in social psychology has examined the effect of social influence on group processes. To examine the conditions under which individuals cooperate to function as a group and the effects of this group formation on the cohesiveness, communication, and morale of group members, two experiments were conducted. A group of three male subjects…

Investigations in Natural Science is a program in secondary school biology, chemistry, and physics based upon the description of science as a quest for knowledge, not the knowledge itself. This teaching guide is designed for use with the 18 biology investigations found in the student manual. These investigations focus on concepts related to:…

Background information, lists of materials needed and procedures used are provided for 16 simple experiments on electricity and magnetism. These experiments are organized into sections dealing with: (1) Edison's carbon experiments (building a galvanometer, investigating the variable conductivity of carbon, and examining the carbon transmitter…

There is little or no uniformity to be found in the skills and knowledge of doctoral students planning to do research in English and reading. (JH)

Explains a study designed to consider the influence of positive and negative affect induced by cognitive mediation on behaviors thought to reflect depression. Concludes that results show fairly strong support for Velten's (1968) methodology and suggest that affect can be manipulated in the laboratory. (Author/EJT)

Presents a laboratory experiment specifically designed for allied health students. The students construct molecular models of amino acids, extract amino acids from their skin with hot water, and chromatographically analyze the skin extract and hydrolyzed insulin. (MLH)

An educational performance contracting project illustrates difficulties of satisfactory implementation as intended when examining climate for the experiment, its design and results, and problems of carrying out the project. (Author/ND)
