Need For Greater Concern For Nutrition In Science Programs, Robert E. Yager

Iowa Science Teachers Journal

Effective teaching of basic nutrition is a major deficiency in the schools of our nation. Although nutrition is one of approximately a dozen central themes generally recognized as comprising biology, it is an area which tended to be de-emphasized during the 1960's and early 70's. Nutrition was usually too applied in nature to be a major focus within the NSF curricula which were organized around the conceptual themes which characterize and unify the various disciplines of science. One of the first changes in the development of the so-called "new courses" of the 1960's was the elimination of any applications of …

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.

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 …

Teaching Creation And Evolution In Iowa Schools, Jack Gerlovich

Iowa Science Teachers Journal

In February, 1977 a bill (H.F. 154) was introduced in the Iowa House of Representatives that read as follows: "If a public school district offers courses which teach pupils about the origin of humankind and which include scientific theories relating to origin, instruction shall include consideration of the creation theory as supported by modern sciences."' In May 1977 the Urbandale School District made a written appeal to the Iowa Department of Public Instruction to consult with experts in the science community to determine if the evidence used to support the creationist theory was credible and should be made available to …
