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 …

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 …

The Tiger Salamander, Michael J. Lannoo

Iowa Science Teachers Journal

Tiger salamanders are harmless members of the Class Amphibia which easily lend themselves to observation and experimentation. As the name amphibian implies, these salamanders have two life forms, an aquatic larval stage and a terrestrial adult stage. Both forms are common and widespread throughout Iowa, yet adults, being terrestrial and less seasonal, are encountered more frequently than the larvae.

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.

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 …

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 …
