Evaluation Of Affective Behaviors Of High School Science Students, Gary E. Downs
Evaluation Of Affective Behaviors Of High School Science Students, Gary E. Downs
Iowa Science Teachers Journal
American education has been in a constant state of change during the last half-century. Some of the changes in science education are being questioned by the critics. Some of the criticism has come about because of the emphasis on subject matter content and very little emphasis, if any at all, on values. Science education must be part of the movement to a more humanistic education for young people. One method that teachers can use to help determine the direction of science education is to try and teach for and measure the affective behavior of their students. This paper is a …

Roots, Richard F. Trump
Roots, Richard F. Trump
Iowa Science Teachers Journal
When I found a way of giving my students a better view of what goes on underground, they started asking better questions, and they found better ways of answering those questions. That was the most exciting aspect of some work I was doing for the Agricultural Research Service (ARS). My assignment was to find ways of using, in the classroom, some of the techniques developed by Dr. Howard Taylor and his associates at Iowa State University involving investigations into root growth.
Outdoor Education At Knoxville, Curt Froyen
Outdoor Education At Knoxville, Curt Froyen
Iowa Science Teachers Journal
Many of the outdoor science activities at Knoxville wouldn't be possible if it weren't for the unusual arrangement of science classes. Students in the environmental science class, which meets during the fall semester, and the field biology class, which meets in the spring, attend class twice a week for two hours straight and once on Friday for one hour. All students are required to either take one of the field classes or general chemistry, as well as a semester in human biology.

Winter Birdfeeding
Iowa Science Teachers Journal
Winter's freezing winds and snow should remind us that many birds maintain permanent residency instead of migrating to warmer climates. Besides finding adequate shelter, their most important task is obtaining a sufficient and steady supply of food.

Trailing The Trilobite, Joseph H. Brown
Trailing The Trilobite, Joseph H. Brown
Iowa Science Teachers Journal
Rocky ledges jutting forth to form stony outcrops along -Iowa's streams, roadcuts and hillsides provide evidence of ancient environments entirely different from the rolling prairies of today. These rocky ledges were laid down in the bottoms of vast shallow seas which covered most of Iowa in its past history. Over great lengths of time, the waters swept back and forth, rising and subsiding, leaving a record in the layers of the earth's materials deposited in their depths. As the seas rose and fell, the deposits buried one another and became layers of conglomerate, sandstone, shale and gypsum. Minerals of calcite, …
The Meter Redefined
Iowa Science Teachers Journal
The current definition of the meter, based on the measurement of the wavelength of a line in the 86Kr spectrum, is 104 times less accurate than the definition of time by the cesium "atomic clock."
Ethics As A Science: Going From "Is" To "Ought", Warren Shibles
Ethics As A Science: Going From "Is" To "Ought", Warren Shibles
Iowa Science Teachers Journal
Two beliefs which serve to prevent teaching, defining, or progress in ethics and morality are: 1. That we cannot derive an "ought" from an "is." We supposedly cannot derive value statements from factual statements. 2. That we cannot define ethical terms in terms of non-ethical terms (naturalistic fallacy). But can we derive an "ought" from an "is?" Does it ever make sense to do so? Let's take a case as it may arise. It is cold outside. I know that a chill may bring on a cold and I wish to avoid catching cold. I then conclude "I ought to …

A Look At Copper, Erwin Richter
A Look At Copper, Erwin Richter
Iowa Science Teachers Journal
The study of copper and its compounds is among the more aesthetically pleasing aspects of chemistry. Copper compounds range in color from white to black, and include virtually all colors of the visible spectrum. The following exercise is designed to explore some of the chemical properties of copper and copper compounds.

A Non-Polluting Method Of Silver Reclamation, Craig A. Perman
Iowa Science Teachers Journal
Pure silver is a brilliant, lustrous, white transition metal occupying the copper subgroup of the periodic table. This metal has been known since antiquity, having been mentioned in Genesis and in pre-dynastic Egypt where it was originally used for coinage and decorative purposes.
Beyond The Metre (Part Ii), Richard S. Thompkins, Vincent N. Lunetta
Beyond The Metre (Part Ii), Richard S. Thompkins, Vincent N. Lunetta
Iowa Science Teachers Journal
This article is the second in a series discussing the wide spectrum of metric units. The first article dealt with some general aspects of the International System of Units (SI) and then went on to consider the metre, square metre, cubic metre and second. This article describes the SI unit of mass, and how units for velocity and acceleration are built using physical laws.

Science-Related Social Issues Survey, Timothy M. Cooney, Jeffrey Blaga
Science-Related Social Issues Survey, Timothy M. Cooney, Jeffrey Blaga
Iowa Science Teachers Journal
During the past several years, many science-related social issues have been of concern to the people of Iowa. Abortion has been an issue. Protests have been made against the Duane Arnold Energy Center nuclear generating plant. Evolution and creationism were debated in the state legislature. In addition, arsenic and nitrates have been found in some municipal water supplies. Other technological issues, such as soil conservation and gasohol, have been making headlines. These societal concerns are often of interest to students in our schools. Important and, as of yet, unanswered questions have been posed about how educators will deal with these …

The Maligned And Misunderstood North American Badger, Richard Lampe
The Maligned And Misunderstood North American Badger, Richard Lampe
Iowa Science Teachers Journal
The common though highly elusive North American badger is seldom seen and often misunderstood. When badgers are encountered by man, the experience is frequently startling to both parties. Impressions based on such limited and stress-filled information are biased. For example, it is widely believed that this member of the family Mustelidae (which also includes skunks, otters and weasels) is vicious, mean and aggressive. However, personal experience with badgers gained from studies over the past 10 years indicates that, although quite capable of defending themselves, badgers are shy, secretive and good bluffers.
