A Philosophical Approach To The Meaning Of Science, James Slock
A Philosophical Approach To The Meaning Of Science, James Slock
Iowa Science Teachers Journal
It would seem to be a rat her simple matter to define what science is and how it operates. After all, a good portion of our high school and college careers have been spent in science classrooms and laboratories. Possible answers might be that science is an organized body of knowledge and that it operates by discovering the truth about nature through the use of scientific method. It seems equally simple to visualize science as a massive pile of bricks with each scientist adding a new brick each time he discovers a new fact or invents a new theory. Further, …
Practical Application Of Basic Research In Hydrogen Bonding, Paul E. Rider
Practical Application Of Basic Research In Hydrogen Bonding, Paul E. Rider
Iowa Science Teachers Journal
It has become common in recent years for non-scientists to react rather disdainfully toward research projects that ad dress what appear to them to be highly specialized areas of interest and which, from their titles, offer little good for mankind. Those of us who spend great portions of our waking hours engrossed in these studies tend to over-react in the other direction by holding our endeavors in an exaggerated esteem that tends to preclude an appropriate assessment of their essential merit. As is usually the case, the proper perspective lies somewhere in between.

Ice - The Common, Yet Strange Substance, Dennis Barnaal
Ice - The Common, Yet Strange Substance, Dennis Barnaal
Iowa Science Teachers Journal
Ice has been the focus of studies by physicists, chemists, geologists and even biologists for many years. Ice represents a basic example of the hydrogen bond which is present in many important organic molecules. In some parts of the world, ice or permafrost is an important constituent of construction. The movement of glaciers and formation of hailstones represent aspects of ice physics. Cell water in living cells appears to be ice-like. However, ice is still not fully understood. An international conference on the physics and chemistry of ice is held approximately every four years.
The Heat Of Fusion Of Ice, Walter J. Gohman
The Heat Of Fusion Of Ice, Walter J. Gohman
Iowa Science Teachers Journal
Students have learned that when heat energy is added to any substance the temperature of this substance increases and, conversely, when heat energy escapes from the substance the temperature decreases. Based upon this concept, the idea of the heat of fusion of ice does not make sense. The idea that each gram of ice a 0° C can absorb 80 calories of heat energy and become a gram of water with the temperature still 0°C does not seem logical. The student may accept the “if you say so" approach, but some meaningful laboratory data will be more convincing. The usual …
New Botany Text
Iowa Science Teachers Journal
Dr. John D. Dodd, Professor of Botany and Plant Pathology at Iowa State University, has just published a new botany text suit able for a one term course in general botany. Course Book in General Botany, published by the Iowa State University Press, emphasizes descriptive rather than the physiological aspects of plants.

Snow (Part I), Janet Morley
Iowa Science Teachers Journal
When most of us think of snow, we think of snowmobiling, skiing, shoveling or poor driving, but there is much more to snow than this. Have you ever really looked at snow?

"Fore" Physics, Rick Zehr
"Fore" Physics, Rick Zehr
Iowa Science Teachers Journal
I have developed an activity which I would like to share, in the hope that it might prove educational as well as enjoyable. In Chapter 1 of the Project Physics there is a brief history of photography, which in itself is quite interesting, but one picture specifically lends itself to additional study. The photograph of the golfer provides the basis for this activity. The students are asked to work in small groups to determine the speed of the ball.

From The Editor's Desk
Iowa Science Teachers Journal
The lead article in this issue suggests that, in the near future, computer outlets may be available in many more schools in Iowa. The utilization of computers in science classrooms has been well documented. The different ways that computers can be used in science classrooms are limited only by the creative imagination of science teachers. Computers are even being used to make out examinations.

Iowa Plan For The Statewide Use Of The Computer For Education, Dean D. Crocker
Iowa Science Teachers Journal
The timely information now available in the application of high speed computer techniques to education may benefit students, school administrators, supervisors and other decision makers alike. Science teachers and students may find assistance through the use of instructional and career guidance applications. Education administrators, supervisors, teachers and other community and state planners can benefit by using the available data in projecting alternative solutions for critical planning issues.
