Roots, Richard F. Trump Jan 1980

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

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.

Trailing The Trilobite, Joseph H. Brown Jan 1980

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, …


Educational Handicaps In Chemistry Students, Charles Douglass Jr. Jan 1980

Educational Handicaps In Chemistry Students, Charles Douglass Jr.

Iowa Science Teachers Journal

Research has been carried out to determine which characteristics and abilities are the best predictors of success in a college level chemistry course. Much of the work has centered on achievement measures such as high school chemistry performance, SAT or ACT scores, and the like. Factors other than demonstrated aptitude and ability are also important to success. Some research has looked at the effect of cognitive styles and motivational factors in attempting to predict success. Recent studies in our department indicate that most students who do not perform well may be thought of as suffering from an educational handicap, where …

Ethics As A Science: Going From "Is" To "Ought", Warren Shibles Jan 1980

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 …
