Due To Technical Difficulties Jan 1981

Due To Technical Difficulties

Iowa Science Teachers Journal

The worst thing about a burning issue is that no one can smell it until there's a fire. We all spend our days deeply engrossed in ourselves, noses pressed to the grindstone. Who can see anything in that position? Then, something ignites a spark - and, suddenly, everyone calls "Fire!"

First Amendment Rights protect freedom of religious choice. Americans are free to practice any religion they choose, or may decide to have no religion. The Federal Government may not establish an official religion and the State may not pass laws that endorse any particular religious concept.


Chemistry Curricula: Past, Present, And Future, Robert W. Hanson Jan 1981

Chemistry Curricula: Past, Present, And Future, Robert W. Hanson

Iowa Science Teachers Journal

At the University of Northern Iowa we have four so-called "Current Curricula" courses - one each in junior high science, biology, chemistry, and physics. Each is preceded in the teaching degree programs by a course called "Orientation to Science Teaching." Most students who take these Current Curricula courses are juniors or seniors and have had at least part of their professional sequence in the College of Education.

Some Ethical Considerations Concerning The Use Of Live Animals In Biology Experiments, David F. Treagust Jan 1981

Some Ethical Considerations Concerning The Use Of Live Animals In Biology Experiments, David F. Treagust

Iowa Science Teachers Journal

As biology teachers we are continually faced with decisions regarding the use of experiments in order to identify, investigate, clarify or illustrate a particular concept or concepts. If an experiment is to be performed we frequently have to decide whether to use live animals, preserved animal specimens, preserved animal organs, fresh animal organs (from, say, the butcher), tissue cultures, audio-visual simulations or even class members as the subjects. Many students, and indeed many teachers, have been reticent about their acceptance of experimenting with live, or freshly killed animals; frequently the issue is settled by reference to such work being in …


Statement Of The Position Of The Iowa Academy Of Science On The Status Of Creationism As A Scientific Explanation Of Natural Phenomena Jan 1981

Statement Of The Position Of The Iowa Academy Of Science On The Status Of Creationism As A Scientific Explanation Of Natural Phenomena

Iowa Science Teachers Journal

Current attempts to introduce 'scientific creationism' into the science classroom are strongly opposed by the Iowa Academy of Science on the grounds that creationism when called 'scientific' is a religious doctrine posed as science. It is contrary to the nature of science to propose supernatural explanations of natural events or their origins. With its appeal to the supernatural, creationism is outside the realm of science.


A Tool For Assessing, Implementing, And Evaluating Science Curriculum (K-12) For Iowa Schools, Jack Gerlovich, Gary Downs, George Magrane Jan 1981

A Tool For Assessing, Implementing, And Evaluating Science Curriculum (K-12) For Iowa Schools, Jack Gerlovich, Gary Downs, George Magrane

Iowa Science Teachers Journal

In the fall of 1977 the Iowa Department of Public Instruction (DPI) began to receive many requests for assistance in developing coordinated science programs. Local schools faced with aging science materials, economic constraints, increasing pressure from publishing companies, and decreasing student reading and computing skills needed guidelines for assessing, implementing and evaluating their science curriculum. The purpose of this tool is to provide such assistance.

Iowa Science Teachers Journal

If the energy in sound waves could be converted into electrical power, it would take the combined output of 1017 mosquito buzzes to provide enough energy to light a reading lamp.


A Method Of Evaluating Computer Programs For High School Physics, David Broadwater Jan 1981

A Method Of Evaluating Computer Programs For High School Physics, David Broadwater

Iowa Science Teachers Journal

Many high schools have access to computer terminals. Such terminals are of limited value if the computer library is not stocked with programs that are integrated into the educational program of the school. There is a need for the evaluation of computer programs with respect to their applicability to various levels of instruction. In this paper, a method of evaluating computer programs for high school physics is outlined.

Thomas Edison was taken out of school because it was thought that he couldn't learn at all. His spelling and grammar were very poor.


The Paradox, James Hungerford Jan 1981

The Paradox, James Hungerford

Iowa Science Teachers Journal

Recent surveys indicate that many young adults blame science and technology for most of society's problems. On the other hand, an even larger number trust that science and technology will solve these same problems. Their expectations are for spectacular achievements from science and technology. Such expectations often stem from an unawareness of the fundamental nature and limitations of scientific inquiry.

The Natural Forest Communities Of Iowa: A Resource In Trouble, Gary Hightshoe Jan 1981

The Natural Forest Communities Of Iowa: A Resource In Trouble, Gary Hightshoe

Iowa Science Teachers Journal

Based on the original United States Land Office survey, it has been estimated that 18 percent of the total state land area was once covered by forest. Today, less than 4 percent of the Iowa landscape remains in forest. In essence, Iowa's forest lands have a value underrated and misunderstood by most of its citizens. Threatened with exhaustion of our natural forest heritage, it is imperative that the citizens of this state awaken at last to the necessity of protecting what is left. The appreciation, conservation, restoration and wise management of our remaining forest resource must play a critical role …

There are several views regarding origins and changes that have occurred on the earth over time. Six day creation, gap creation, progressive creation, theistic evolution, creationism, evolution, and planetary seeding are terms used to describe some of these views. The contrasts among these ideas, especially between creationism and evolution, have been discussed publicly.


Science Anxiety: How Can We Reduce It?, George Davis Jan 1981

Science Anxiety: How Can We Reduce It?, George Davis

Iowa Science Teachers Journal

Science anxiety is a new name for a phenomenon that all science teachers, regardless of experience, are familiar with. Science anxiety is a fear that many bright and capable students have of scientific studies. This fear carries with it a conviction that they cannot, regardless of effort, understand science. Science anxiety is a very effective sieve that keeps many talented people from careers in science. Those science anxious students who enter teaching act as carriers of the anxiety, thereby infecting their students. Finally, science anxious students become members of our community and contribute to the growing climate of antiscience attitudes …

Potential New Iowa Multi-Use Crops For Oils And Hydrocarbons, Russell A. Buchanan Jan 1981

Potential New Iowa Multi-Use Crops For Oils And Hydrocarbons, Russell A. Buchanan

Iowa Science Teachers Journal

Many green plants contain, on a dry weight basis, more than 5 percent oil plus hydrocarbon that is not concentrated in storage organs. In these plants, oils and hydrocarbons (botanochemicals) are distributed throughout major plant tissues often as the major component of a latex. Although there has been little past interest in processing whole plants for botanochemicals, there is now great interest in these new and renewable sources of raw materials and energy. Various plant species are being regarded as potential "gasoline trees", as possible domestic sources of natural rubber and plastic, as new sources of industrial feedstocks or even …
