Energy Crunch

Iowa Science Teachers Journal

Chop up some spinach, throw in some fat, add water, sunlight and a few other chemicals, and you may end up with a recipe for easing the energy crunch. At the Michigan State University laboratory of biophysicist Dr. H. Ti Tien , these ingredients are used to make a device for generating electricity directly from sunlight.

Films, Fractions, Ratios And Reels, David Duncan, Bonnie Litwiller

Iowa Science Teachers Journal

Many teachers show films in their classes to supplement scientific concepts. In addition to learning from the content of the film, significant mathematical ideas may be found by observing the motions of the projector itself.

The 1982 Outstanding Service Award, Carolyn Brockway

Iowa Science Teachers Journal

The Iowa Science Teachers Section of the Iowa Academy of Science annually presents a deserving member with the "Outstanding Service Award." This year, Dr. Joe Moore, the science and environmental education consultant of Keystone AEA in Elkader, Iowa was chosen to receive the award. The award was presented at the annual Fall Conference in Marshalltown on November 11.

A Multiple Evaporator For General Chemistry, H. I. Feinstein

Iowa Science Teachers Journal

Many experiments require a hood clue to the evolution of hazardous fumes. One such experiment involves the use of nitric acid in the determination of combining ratios of certain metals, e.g., tin and oxygen. Where large classes are the rule, as in general chemistry, and the number of fume hoods is limited, the progress of the class is slowed considerably if individual set-ups are used.

Wood Won't Work, James Hungerford

Analysis Of The Problems In Science Education And Recommendations For Resolution, George Burnet

Iowa Science Teachers Journal

The quality of precollege mathematics and science education in our schools and the implications for all sectors of American society have been articulated in the Commission on Precollege Education in Mathematics, Science, and Technology's report, Today's Problems, Tomorrow's Crises (1982) and in numerous other reports, articles, publications and public fora. Since July 1982 the Commission has been collecting information and suggested solutions from a broad base of institutions, organizations, and expert observers.

Governor's Task Force Report On High Technology In Iowa: Results And Applications To The Crisis In Science Education, David H. Swanson

Iowa Science Teachers Journal

Governor Robert Ray, on May 18, 1982, directed a High Technology Task Force to examine the feasibility of the development of high technology industries in Iowa. This task force after 5½ months of study, made its report to the governor. The report found that 75 percent of the new U.S. manufacturing jobs created during the past 25 years were in seven basic industry groups. These industries were generally described as high technology. The report also concluded that in the future manufacturing employment increases were most likely to occur in high technology industries. Considered major among the locational factors of high …

The Search For Excellence In Science Education, John E. Penick

Iowa Science Teachers Journal

In 1976 several NSF funded studies revealed the current state of science education in the United States. In 1978, a synthesis of the more than 2,000 pages of information from those three NSF reports and the NAEP data was begun by twenty-three science educators throughout the U.S. The synthesis researchers worked independently in small teams, each focusing on one aspect of science education: elementary science, biology, physical science, science/technology/society, or inquiry. A critical part of the synthesis analysis was developing a description of an ideal or desired state for a focus area and then comparing the actual to the desired …

A Look At Earth Science Teacher Needs, Peter A. Rubba

Iowa Science Teachers Journal

In preparation for designing a number of inservice activities for science teachers, the author completed a needs assessment on a random, stratified sample of the grade six through twelve science teachers in Illinois. The survey was carried out using the Moore Assessment Profile (MAP), an instrument which had been developed specifically to identify the needs of inservice science teachers.

A Refined Plan For Elimination Of Unwanted/Dangerous Chemicals, Jack Gerlovich, Ron Kolpa, Frank Kilpatrick

Iowa Science Teachers Journal

Through the cooperative efforts of numerous state agencies, the state of Iowa has refined its plan for safe, expeditious and effective identification and redistribution and/or disposal of hazardous chemicals from school science storerooms. Following assessment of high school and community college storerooms, review of Environmental Protection Agency (EPA) guidelines for handling and disposal of hazardous substances, review of related chemical literature, and testing at the University of Iowa, a list of 100 "chemicals considered more hazardous than their education value" was synthesized.

The Basics Of Dieting, Erwin W. Richter

Iowa Science Teachers Journal

Much has been written and much more will be written concerning dieting and weight loss. There are fad diets, carbohydrate free diets, fat free diets, liquid protein diets, and others too numerous to mention.

Perceptions Of Science Of Third, Seventh, And Eleventh Grade Students Enrolled In Cedar Rapids (Iowa) Schools, Stuart O. Yager, Robert E. Yager

Iowa Science Teachers Journal

As a part of the Third Assessment of Science for the National Assessment of Educational Progress (National Assessment, Note 1.), an extensive battery of items dealing with the affective domain were included for the first time. Information for the National Assessment of Educational Progress is gathered from a stratified sample drawn from the entire United States. All questions are reviewed by education specialists (including science educators, measurement experts, and lay persons). The questions are administered to 2,500 persons selected to represent varying age levels. For NAEP studies, four samples are used, namely 9, 13 and 17-year-olds and a young-adult sample.

The Identification Of Unknown Bacteria, Steve Ziser

Iowa Science Teachers Journal

A major activity of most college level introductory microbiology courses is the identification of one or more unknown bacterial species. The ways suggested in many lab manuals for identifying bacteria are often unorganized and difficult to follow. In addition, the huge volume of information often required to make a diagnosis may overwhelm beginning microbiology students who are largely incapable of weighing the importance of many of the tests in trying to decide how to best proceed with the identification. Microbiology manuals too often overlook the fact that identification is an orderly process of moving from general characteristics to more specific …

Element-Ary Puns, Rita K. Voltmer, Jody M. Hines, James L. Kelly

Iowa Science Teachers Journal

The periodic table offers a lot of information, most of which is usually not used by high school students. However, it is important for students of chemistry, biology and physics to have some background related to the elements that make up the periodic table. Several students were working with a periodic table and realized they could make studying the elements more enjoyable by making up some statements that led to the actual naming of the element. For example: If you want to catch wild horses, europium.

The Atoms Family - Or - Ionic Man, James Novotony

Iowa Science Teachers Journal

Since concepts involving invisible, intangible particles are especially difficult for junior high students to understand, how does a student know that atoms, molecules, electrons, and ions really exist? Are these particles just the figment of someone's imagination?

I decided some years ago that students needed more than an explanation of a concept involving atomic particles. Pictures are helpful to serve as an extension of a verbal teaching method.

Osmosis: A Different Approach, Dennis Sievers

Iowa Science Teachers Journal

Traditional experiments on osmosis usually include a study of the glucose-water experiment but lack a connection to a living system. This is a fine experiment but fails to give students a true picture of what is occurring in a living system. The following experiments describe a method of examining osmosis and some factors that can have an effect on it in a living blood cell.
