Science For The Educationally Uninvolved Student, Joe R. Moore

Iowa Science Teachers Journal

In looking at science in today's high schools, one can come up with the following statistics. There are approximately four million students at each grade level between grades nine to 12. In biology classes we find 1.85 million students, in chemistry about 1.25 million and in physics only .25 million students. Over half of these students are enrolled in terminal or "slow-track" science courses, where they are neglected or forgotten, taught by the beginning teacher in a non-lab-oriented classroom. Almost every high school has a science course where the so-called "slow-learners" have been placed. These courses may come under a …

What Is A.T.T.V. Biology?, Charles Frederick

Iowa Science Teachers Journal

A.T.T.V. Biology (Audio-tutorial Television Biology) is an approach to teaching a subject which is paced by closed circuit educational television. The curriculum material of the course is divided into units of work (modules). Each module consists of one week's classroom activities. For each module there are objectives and learning experiences to be completed within that week. The module suggests the minimal work expected of the student, and the student works directly from the module guide. When the student has completed the minimal learning experiences, he is free to pursue additional activities that are listed in the module. This is where …

Rebuilding A Tornado To See What Makes It Tick

Iowa Science Teachers Journal

Hurricanes can be studied from airplanes flown through them and from instruments located in their paths. But even if a meteorologist or engineer could predict the narrow path of a tornado, any instruments he might place in its path would be swept away by the force of the storm.

Nsf Awards $12 Million For Science Programs At Colleges And Universities

A Learning Activity Package Approach To Junior High School Science, Jerry Cunningham, Ross Iverson

Iowa Science Teachers Journal

Our goals were to have a low-structured student centered program that made the best use of our physical facility, equipment, and teacher power. As a result, we formulated a design which included a format, procedures, and a set of materials. We feel that our design is adaptable to many situations and may provide some ideas for you. The courses we teach are exploratory. We hope to offer the student a wide variety of new experiences while developing a continuing interest in the study of science and a systematic approach to solving problems.

A Plan For A Temporary Insect-Killing Jar, William G. Bennett

Iowa Science Teachers Journal

Science teachers, whether they are teaching elementary, high school or even college students, often include insect collecting as a unit of study. They are always confronted with what recommendation to make as a successful means of killing the specimens.

A Brief Study Of The Place Of The Computer In The Library, William Mitchell Andrews

Graduate Research Papers

When considering adapting the computer to library use, there appear to be four general areas where usage would be most practical. The first area might be labeled "library housekeeping operations," which would include the ordering and receiving of monographs and serials,
circulation control of library items and preparation of catalogs and listings of many kinds. The second area would consist of cataloging and allied content analysis operations designed to assign to each item subject identifiers, as well as call number or related classification information. The third area would be composed of storage and retrieval operations, which make it possible for …

The School Librarian And The Elementary Social Studies Curriculum, Gerald Richard Eberle

Graduate Research Papers

The social studies curriculum is in an era of transition. It is a complex, multidimensional, often confusing, but tremendously challenging subject. Because research and study in this area double and redouble in very short periods of time, educators face the problem of remaining informed of new developments.

As the school librarian participates in all areas of curriculum planning, a knowledge of theory and practical application is necessary. In the social studies curriculum a review of its evolution in American education is helpful. This includes general aims and objectives, its history in American education, present criticism of its relevance to today's …

Space Travel To The Moon And Kepler's Dream, Paul B. Selz

Proceedings of the Iowa Academy of Science

Johann Kepler advocated Copernicus's heliocentric theory in his Dream and Notes. He imagined how a moon dweller would see the solar system and the conclusions he would draw. Then by reversing the point of view to the earth, Kepler showed that the same conclusions would follow. This involved concepts of mass, inertia, gravity, acceleration, velocity, and the driving force in a trip to the moon. Twelve years before Newton's birth in 1642, Kepler published in this little known dream ideas which Newton later developed. Kepler's ideas concerning the moon's distance, motion, and conditions to be met in space are reviewed.

A Study Of Chromium (Iii) Complexes Of O-Phenylenediamine, Barbara J. Kacena

Dissertations and Theses @ UNI

Chromium(III) complexes of o-phenylenediamine were prepared by mixing hot 1-butanol solutions of transtetraaquadichlorochromium(III) chloride 2-hydrate and o-phenylenediamine. From the elemental analyses of four preparations, the empirical formula was determined to be CrCl₃C₁₂H₁₈N₄O_1.7. It was found, by the analysis of infrared spectra, that o-phenylenediamine acted as bidentate ligands and, by chloride analysis, that each molecule of the complex contained one free chloride ion. The following formula was proposed: [CrCl₂(C₆H₈N₂)₂]Cl·xH₂O.

New Conceptual Design Of The Isu Tornado-Simulation Wind Tunnel, C. T. Hsu

Proceedings of the Iowa Academy of Science

Iowa ranks fifth in the nation for the annual tornado frequency per area. Although solutions for avoiding tornado formation are rather remote, if not impossible, understanding this formation process and its mechanism of operation must be advanced first. Current theories are still unsatisfactory and inadequate. A new concept of tornado modeling, resulting from extensive tornado literature studies and swirling rocket nozzle flow research, is proposed here. Based on this concept, the Iowa State University tornado-simulation wind tunnel is designed for better simulation of tornado flow.

Cleaner Air Ahead?

Iowa Science Teachers Journal

Environmental Protection Agency Administrator Ruckelshaus has announced that a prototype engine developed by EPA and the U.S. Army has met EPA's 1976 emission standards in initial tests. EPA, the Army, Ford Motor Co. and Texaco, Inc. have been working on the project for the past two years as part of President Nixon's program to develop a virtually pollution free automobile engine.

A Study Of Physics, Chemistry And Advanced Science Enrollments In Iowa's Area Ten With Reference To Enrollment Patterns In The State Of Iowa, Richard E. Mcqueen

Iowa Science Teachers Journal

This study was initiated under the assumption that advanced science courses could be shown to detract from physics enrollments, thus establishing one possible cause of the continuously declining enrollments in physics in Iowa's Area Ten and nationwide. Initial work failing to support this relationship, a study of chemistry enrollments was added, chemistry enrollments being felt to be indicative of emphasis on science, with or without an advanced course. Information on enrollments in Area Ten was taken directly from teachers' responses to a questionnaire on such enrollments for 1969-70, received from all 43 public and seven parochial, private or special schools …
