Single Cell Protein: The Future Food, D. O. Hitzman Jan 1982

Single Cell Protein: The Future Food, D. O. Hitzman

Iowa Science Teachers Journal

The population of the world is now over 4 billion, with approximately two-thirds of this population being in regions characterized as being underdeveloped. Today there are 200,000 more people than there were yesterday, with about 10,000 persons estimated as dying each week from lack of food. By the year 2000, it is estimated that 6 to 7 billion persons will live in the world. Current global surveys measuring food supply per person indicate severe undernutrition (too few calories) and an unbalanced diet (too little protein). The most critical single shortage in the world food supply is protein, vital to the …

Communication By Writing: A Basic Part Of Science Education, Donald L. Schmidt, Robert S. Tapply Jan 1982

Communication By Writing: A Basic Part Of Science Education, Donald L. Schmidt, Robert S. Tapply

Iowa Science Teachers Journal

No responsible educator would deny that an educated person should have the ability to express himself in writing. One must not lose sight of this basic idea when teaching science. Far too often, science students communicate through definitions, symbols and technical terminology without making the attempt to combine a series of meaningful phrases which communicate an individual's understanding of science in a comprehensible way. The responsibility for teaching communication by writing in science rests clearly with the science teacher, who must develop strategies within the framework of the discipline to involve students in the process of writing.

Demonstrating Density Jan 1982

Demonstrating Density

Iowa Science Teachers Journal

The concept of density is difficult for the average seventh or eighth grade student to understand. Most of the current physical science textbooks, however, include it as one of the characteristic properties used to distinguish between various materials. The following demonstration has proven useful in promoting inquiry discussions when the concept of density is introduced.

Octane Jan 1982

Octane

Iowa Science Teachers Journal

The octane rating of a gasoline is an indication of how a gas burns. Straight-chain hydrocarbon molecules are unsuitable for use in automobiles because they burn too rapidly causing the engine to knock and ping.

Notes On Creationism

Iowa Science Teachers Journal

In a landmark decision, federal judge Overton struck down a creation science law in Arkansas. Judge Overton concluded that creation science is "simply not science" and that no group may use the organs of government to force its religious beliefs on others.


A New Age For The Universe?, Darrel Hoff Jan 1982

A New Age For The Universe?, Darrel Hoff

Iowa Science Teachers Journal

The question of the age of the earth, the solar system, stars galaxies and the whole universe have intrigued man for a long time. The story of Bishop Ussher's use of biblical chronology in the early 1600s to date the creation at 4004 B. C. is the story of the earliest attempt to arrive at an answer to this question. The work of geologists, and physicists during the 1800s called this date into serious question. Investigations based on stratigraphy, salination of the oceans, and heat flow from a cooling earth put the age much greater than Ussher's estimate. Although these …

Women In Science: A Developing Country, Doris Simonis Jan 1982

Women In Science: A Developing Country, Doris Simonis

Iowa Science Teachers Journal

Because teenaged girls generally avoid classes in physical sciences and advanced mathematics, they reduce their career options. Even highly talented young women do not pursue science in numbers proportionate to their share of the college student population.

One way of examining this problem of underrepresentation is to recognize that women have been effectively isolated from the kinds of encouragement, feedback and experiences that their brothers have had in family, educational, social and occupational situations. Independence in thought and action rarely wins praise for a girl, and mechanical as well as intellectual attainments are likely to get approval only if they …


Let Me Out, Cherin Lee Jan 1982

Let Me Out, Cherin Lee

Iowa Science Teachers Journal

Why are walls, floors, and ceilings so inviting? What is the lure of a classroom when compared to the lure of being outside? It's quite surprising that more science students and teachers aren't clamoring "Let me Out!"

Science educators are frequently looking for activities to take them out of classroom settings. Such an activity evolved during a seminar at UNI called Innovative Biology Teaching. The challenge was to develop a teaching technique for a single concept using the outdoors at the particular time of the assignment. This was late October and early November, not a favorite time for many teachers …

The Role Of The Laboratory In High School Physics, Hank Biere Jan 1982

The Role Of The Laboratory In High School Physics, Hank Biere

Iowa Science Teachers Journal

I'm sure many articles have been written on the role or use of the laboratory in high school physics. So many, in fact, that I'm not sure I can add much of anything that is really new and unique. In spite of the fact that during the last 10 to 12 years we've become very much aware of writing objectives (behavioral type), we've probably not given much thought to objectives of the lab. In some cases we come to a certain place in the book and it's time to do a lab; so we do it without much thought as …


Wisconsin Academy Stir Report: A Vascular Flora Of Snake Creek Corridor, Wisconsin, Thomas L. Eddy Jan 1982

Wisconsin Academy Stir Report: A Vascular Flora Of Snake Creek Corridor, Wisconsin, Thomas L. Eddy

Iowa Science Teachers Journal

In November, 1978 my advanced biology class received a research grant through the Wisconsin Junior Academy's (WJA) Student-Teacher Integrated Research (STIR) Program. Funding for the program was provided by the Wisconsin Academy of Science, Arts, and Letters-Youth Program and by the American Association for the Advancement of Science. The basic purpose of STIR is to promote quality high school science and social science research by sponsoring grants which can be used to purchase equipment and supplies.


Is School Science An Endangered Species?, Jack Gerlovich, Thomas Budnik Jan 1982

Is School Science An Endangered Species?, Jack Gerlovich, Thomas Budnik

Iowa Science Teachers Journal

2. Is school science

A recent National Science Foundation report warns that the United States faces immediate shortages of engineers and computer professionals; it also sees a trend "toward virtual scientific and technological illiteracy in the population at large."(12)

Science News reported that the nation's commitment to excellence and international primacy in science and mathematics has waned markedly over the past 15 years. Not only the scientific community, but the nation as a whole, will suffer if drastic changes aren't made quickly. In an age when scientific and technical literacy is becoming increasingly necessary to function in our society, increasing …
