Team Orientation In The Chemistry Laboratory, David N. West Jan 1975

Team Orientation In The Chemistry Laboratory, David N. West

Iowa Science Teachers Journal

The importance of laboratory experience for students is widely accepted by chemistry educators and usually includes the following behavioral objectives: 1. Training in the scientific method. 2. Developing skills with laboratory apparatus. 3. Learning and applying chemical theory. 4. Communicating laboratory results. It is the opinion of this writer that through a team orientation approach to instruction other behavioral objectives can be attained in laboratory situations that are also useful to students pursuing professional careers in chemistry.


Coal? What's That? Jan 1975

Coal? What's That?

Iowa Science Teachers Journal

In any analysis of the energy resources now available to the United States of America, coal occupies a dominant if not a preeminent position. The very fact that, within the borders of the U.S., there is more energy in the form of coal (more than three trillion tons) than in all of the other combined resources of fossil fuel-petroleum, natural gas, oil shale, and bituminous sandstone-makes coal loom as our most important source of energy for the remaining years of this century, and perhaps for centuries to come.


A Pound Of Prevention: Teacher's Guide To Behavior Problems, James L. Hymes Jr. Jan 1975

A Pound Of Prevention: Teacher's Guide To Behavior Problems, James L. Hymes Jr.

Iowa Science Teachers Journal

They come to school with one big urge: to be liked by the other children, to find a place they can fit in. It is not a question of being in or out; IN they have to be. Children have only one choice: to be in on something good or to be in on something bad. No child can stand to be ignored. It feels better to be noticed for swearing, or for mistakes, or for forgetting, or for silliness, than not to be noticed at all.


On Appreciating Science Jan 1975

On Appreciating Science

Iowa Science Teachers Journal

The scientific attitudes which should be developed are: An intense curiosity about the world in which we live; A firm understanding that every effect has a cause, and every cause is the effect of a prior cause; A firm belief in truth; Making careful and accurate observations; Weighing all the evidence before drawing a conclusion; Appreciating the debt owed to scientists of the past.


Earth Incorporated, Robert Rienow, Leona Train Rienow Jan 1975

Earth Incorporated, Robert Rienow, Leona Train Rienow

Iowa Science Teachers Journal

"Earth" is a proper name. Do we speak of "the mars," or of "the jupiter," or of "the venus"? Then why "the earth"? It is a degradation of both our thinking and our very special planet.

Algae And Energy, James J. Hungerford Jan 1975

Algae And Energy, James J. Hungerford

Iowa Science Teachers Journal

The extent to which algae contribute to human welfare is often forgotten, ignored or unappreciated. Many types of algae serve as bases in commercially prepared foods and condiments. Algal products are used in cosmetics, textiles, pharmaceuticals and paints. In Asia, algae are often mixed and served with rice and fish to supplement the human diet. In coastal areas of the world, kelps are often chopped as food for livestock. The alga Poryphyra is cultivated in Japan to supply a 65 million pound annual market.

Trends In Secondary Science Enrollments In Iowa, Gary Downs Jan 1975

Trends In Secondary Science Enrollments In Iowa, Gary Downs

Iowa Science Teachers Journal

Enrollment data were collected from the district administration for the five reported years starting with the 1968-69 school year. The data for the 1973-74 school year were collected at the school level. Collection at the school level should provide a more representative data bank for the academic programs. All the science offerings were grouped into the following seven categories: biology, chemistry, earth science, enrichment science, general science, physical science, and physics. It is interesting to note that in the 1968-69 data collection only 19 different courses were reported. In the succeeding years, 25, 56, 71, 74, and 96 were reported …


Student Philosophy In Science Class, Owen Primavera Jan 1975

Student Philosophy In Science Class, Owen Primavera

Iowa Science Teachers Journal

As a science teacher I know that facts are vital parts of teaching chemistry or biology, and that the better students understand chemical and biological systems the better they will understand how organisms function. But more than facts seems to be needed to teach ecology.


Iowa Academy Of Science Celebrates Centennial Anniversary Of Founding, Robert W. Hanson Jan 1975

Iowa Academy Of Science Celebrates Centennial Anniversary Of Founding, Robert W. Hanson

Iowa Science Teachers Journal

April 17-19, 1975, marks the observance of an important historical event in Iowa, for it was in 1875 that Charles E. Bessey and a handful of scientists and medical men conceived the original Iowa Academy of Science. One hundred years have produced fantastic changes in life in Iowa, and the Academy of today has almost forgotten its heritage. It has grown from a small fellowship of men dedicated to furthering scientific work in Iowa to 1,400 members-a sizable cross section of the entire scientific community representing pure and applied research, conservation activity, engineering, economics and all levels of education and …


On The Feasibility Of Coal-Driven Power Stations, O. R. Frisch Jan 1975

On The Feasibility Of Coal-Driven Power Stations, O. R. Frisch

Iowa Science Teachers Journal

The recent discovery of coal (black, fossilized plant remains) in a number of places offers an interesting alternative to the production of power from fission. Some of the places where coal has been found show indeed signs of previous exploitation by prehistoric men, who, however, probably used it for jewels and to blacken their faces at religious ceremonies. The power potentials depend on the fact that coal can be readily oxidized, with the production of a high temperature and an energy of about 0.0000001 megawatt days per gram. That is, of course, very little, but large amounts of coal (perhaps …

Seeing Sound, Sondra Waltz Jan 1975

Seeing Sound, Sondra Waltz

Iowa Science Teachers Journal

Making sound visible is a useful activity in teaching students the concepts that sound is caused by vibrating objects and that different sounds are caused by different types of vibration. This particular activity makes it possible to see the sounds produced by observing a vibrating, metal plate. As the plate produces sound it vibrates violently in some areas and not at all in other regions. If a small amount of very fine sand or poppy seed is sprinkled on the plate as it vibrates, the seeds will move to areas where vibration is minimal and form distinct distributional patterns on …

A Computer Assisted Environmental Education Resource Program, Sara K. Smerud, Gary Thomas, Tim Keenan, Dale Nimrod

Iowa Science Teachers Journal

Northeast Iowa is an exceptionally beautiful and unique region. Environmental education in the schools and communities of this area is a vital factor in enabling citizens to take a reasoned approach to the conservation and management of this region. Two observations precipitated the action which resulted in the project described in this paper. The first was that the local resources were vulnerable to being utilized in a potentially harmful manner and secondly, teachers did not seem to be taking full advantage of their local resources in their classroom instruction.

Food From Newspaper Jan 1975

Food From Newspaper

Iowa Science Teachers Journal

Cellulose is the most abundant organic material which can be used as a source of food, fuel and chemicals. The net world-wide production of cellulose is estimated at one hundred billion tons per year. This is approximately 150 lbs. of cellulose per day for each and every one of the earth's 3.9 billion people. The energy to produce this vast quantity of cellulose comes from the sun and is fixed by photosynthesis.

Student Programs In Retrospect, Brian J. Awbrey Jan 1974

Student Programs In Retrospect, Brian J. Awbrey

Iowa Science Teachers Journal

Science may often be considered a discipline of absolutes and systematized knowledge, but science education in Iowa need not be so. To the young and enthusiastic Iowa student scientist there are a number of educational opportunities available that are exciting and relevant, as well as several which take place outside of the classroom. These extracurricular opportunities are designed to allow the secondary science student to realize a few of his educational aspirations while interacting directly with other professionals and student scientists from the state. Since I have been involved personally with some of the unique Iowa science educational opportunities as …
