Human Skin Temperature And Biological Clocks: A Laboratory Exercise For Physiology Students, K. A. Langley, G. E. Folk Jr.

Iowa Science Teachers Journal

A simple laboratory experiment is described, consisting of taking the mean temperature between two fingers of human subjects. The results from comparing male and female students is presented. The change in skin temperature over four hours is documented, to demonstrate the importance of doing standardized experiments at the same time of day.

The Atoms Family - Or - Ionic Man, James Novotony

Iowa Science Teachers Journal

Since concepts involving invisible, intangible particles are especially difficult for junior high students to understand, how does a student know that atoms, molecules, electrons, and ions really exist? Are these particles just the figment of someone's imagination?

I decided some years ago that students needed more than an explanation of a concept involving atomic particles. Pictures are helpful to serve as an extension of a verbal teaching method.

Osmosis: A Different Approach, Dennis Sievers

Iowa Science Teachers Journal

Traditional experiments on osmosis usually include a study of the glucose-water experiment but lack a connection to a living system. This is a fine experiment but fails to give students a true picture of what is occurring in a living system. The following experiments describe a method of examining osmosis and some factors that can have an effect on it in a living blood cell.

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 …

One hundred recent high school graduates representing every state in the nation arrived at Camp Pocahontas near Bartow, West Virginia on July 7 to begin a three-week visit to West Virginia as delegates to the National Youth Science Camp (NYSC).

Diatoms (Part Iv): Identification, James Hungerford

Iowa Science Teachers Journal

Previous articles in this series (Vol. 15(3); 1978) (Vol. 16(3); 1979) (Vol. 19(1); 1982) discussed the collection and preparation of diatoms for laboratory study. This article will deal with the identification of diatoms.

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.

Relevance In The Science Curriculum, Marlow Ediger

Iowa Science Teachers Journal

Selected educators are showing considerable concern pertaining to the lack of emphasis placed upon the science curriculum in the school/class setting. Reasons given in needing to stress increased priority in teaching science include the following.

Aerospace Education Council Of Iowa, Kenneth W. Sand

Iowa Science Teachers Journal

Few people know that there is an Aerospace Education Council of Iowa, though it is entering its 25th year of existence. On December 17, 1956, almost a year before Sputnik, Iowa established an Air-Age Education Council under the auspices of the State Department of Public Instruction. This organization was to sponsor appropriate research, suggest needed curriculum change, and encourage the incorporation of air-age information in all areas of the curriculum, particularly in the social, physical and natural sciences.

Frog Population On Decline

Iowa Science Teachers Journal

The frog for many people represents a most memorable event of their high school days. But the frog soon may be a thing of the past in the high school biology class. There is a growing frog shortage.

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.

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 …

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.

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 …

Metric Poster Series Available For Testing

Iowa Science Teachers Journal

NSTA has developed a series of six posters which will be distributed as centerfolds in The Science Teacher magazine. The poster series is a product of the NSTA's International System of Units Material Development Project, which is funded by the United States Department of Education.

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 …

Chem Gems And Joules

Iowa Science Teachers Journal

About thirty years ago it was discovered that crunching on mint Lifesavers will produce green sparks and a crackling noise. Peppermint Lifesavers will produce similar results. According to Lifesavers, Inc. of New York, the mint Lifesavers contain sugar and methyl salicylate (a component of the mint flavoring). When these two compounds are crunched together, a crystalline energy is produced which stimulates the methyl salicylate to emit light. The process is known as triboluminescence.
