Beyond The Metre (Part I), Richard S. Tompkins, Vincent N. Lunetta Jan 1979

Beyond The Metre (Part I), Richard S. Tompkins, Vincent N. Lunetta

Iowa Science Teachers Journal

This article is the first in a series discussing the wide spectrum of metric units. Metric education programs typically avoid measuring force, energy, and other physical quantities. Specialized units like the joule and pascal, however, will be appearing more and more frequently. How many Americans can confidently interpret a label rating a light bulb in lumens? This series of articles for the general reader will review the history of the metric units, the rationales behind their definitions and the fine points of their usage. Examples and exercises will relate the special units to every day experiences. This initial article will …

Public school energy costs have soared nationally 150 percent since 1972-73. According to Educational Facilities Laboratories (EFL), that represented a $50 expenditure per student during the 1977-78 academic year (1). "School energy costs have doubled in the past 5 years .... Districts surveyed reported hikes ranging from 35 percent to over 400 percent, the average being 110 percent."

Utilization Of Wave Energy, Walter R. Schmitt Jan 1979

Utilization Of Wave Energy, Walter R. Schmitt

Iowa Science Teachers Journal

When looking upon an aroused sea, many wonder how this seemingly large energy resource could be used. Inventive minds have gone to work on devices of all kinds - pumps and bellows, buoys, barges, and ramps, surface and subsurface siting, using alloys and plastics, etc. -generally based on mechanical or hydraulic principles. They would probably all work (if somebody would build them), but none thus far have been shown to do so profitably.

Building Rapport And Changing Attitudes, Owen Primavera Jan 1979

Building Rapport And Changing Attitudes, Owen Primavera

Iowa Science Teachers Journal

During the past few years there seems to be a growing apathy on the part of high school students towards education. It seems that many are weaker in the basic skills of reading, writing and mathematics and could care less about their progress. Why do students feel this way about education and what can educators do to improve the situation?

Tetrahymena: Cell For All Seasons, Eugene C. Bovee Jan 1979

Tetrahymena: Cell For All Seasons, Eugene C. Bovee

Iowa Science Teachers Journal

Certain protozoa have often been the cellular animals of choice for research and teaching in the past 100 years. In 1926, Asa Schaeffer (20) placed "the amoeba" at the pinnacle for animals that serve as primary research tools, along with the dog and the frog. Paramecium (one or more of its species) and Euglena (one or more of its species) are other protozoa (the latter, also an alga) well-known and oft-employed in both teaching and research. In the past 40 years, however, another protozoan has gained prominence in research, equalling - even superseding - the three mentioned above. Its generic …

The Earth's Gravity Field, Robert S. Carmichael Jan 1979

The Earth's Gravity Field, Robert S. Carmichael

Iowa Science Teachers Journal

Curiously, books in Iowa have more "gravity" effect in them than even TIME suspected. In fact, due to gravity effects in the State, a) the same book would weigh less in Des Moines than it would in the town of Anita, 50 miles (80 km) to the west. b) a quick way to lose weight is to travel from the north-central Iowa town of Blairsburg to the nearby town of Wellsburg.

Corn To Alcohol, A. C. Haman Jan 1979

Corn To Alcohol, A. C. Haman

Iowa Science Teachers Journal

The combination of critical fuel shortages and zooming oil prices have led to the possibility of converting corn to an alcohol fuel, a process that has been known for some time. The benefits offered by an alcohol-fuel industry are substantial, among a few are: the fuel source is renewable each year; domestic alcohol fuel reduces dependence on oil imports; and fuel alcohol burns clean reducing pollution. The economic impact to the state economy is obvious.
