Consumption Of Foods With Additives And Other Chemicals: Polychemical Use Or Abuse?, Charles A. Frederick Jan 1978

Consumption Of Foods With Additives And Other Chemicals: Polychemical Use Or Abuse?, Charles A. Frederick

Iowa Science Teachers Journal

The problem of providing an adequate food supply to feed the world's hungry is and has been a major concern among many scientists, politicians and other leaders representing many sectors of American society. As a result of such concern, every conceivable avenue is now being explored to find new ways whereby new crops and foodstuffs can be raised or developed to meet the world's demand. In Geneva, Switzerland in 1975, some members of the World Health Organization (WHO) indicated that "the continuing.increases in the world population without a comparable increase in the available amount of conventional foodstuffs must stimulate further …

Science And Mainstreaming The Educable Mentally Retarded Students, Muhammad Hanif Jan 1978

Science And Mainstreaming The Educable Mentally Retarded Students, Muhammad Hanif

Iowa Science Teachers Journal

The concept of mainstreaming rein forces the belief that all children are capable of learning if education is individualized and attention is given to learning styles, rates of learning, and individual capabilities. It is now widely accepted that children with mild learning impairments should no longer remain segregated and confined to separate classroom situations during their entire day in school. Effective mainstreaming addresses the academic and social needs of all youngsters and functions in the least restrictive environment. The basic assumption that the large majority of handicapped children can be absorbed into regular classrooms with adjustments and adaptations in the …

Lab Safety

Iowa Science Teachers Journal

It has been argued that contact lenses offer a great deal of protection from damage by particles and chemicals in the science laboratory. According to NIOSH nothing could be further from the truth. An eye that has received a chemical splash should be irrigated with water until the material has been completely removed.

Entry Into Elementary Science Through Live Animals, Stanley L. Weinberg Jan 1978

Entry Into Elementary Science Through Live Animals, Stanley L. Weinberg

Iowa Science Teachers Journal

Some years ago I did a series of animal behavior film loops for the Ealing Company. The film loops sold well. Their distribution has been taken over by a subsidiary of CBS and they still sell. The series has been a commercial success. But I judge it a pedagogical failure.


Individualized Chemistry For The Gifted Student, Floyd Sturtevant, Kenneth Hartman, James Jones Jan 1978

Individualized Chemistry For The Gifted Student, Floyd Sturtevant, Kenneth Hartman, James Jones

Iowa Science Teachers Journal

Through a Teacher Incentive Award from the Iowa Department of Public Instruction, the honors chemistry course of Ames Senior High School has been converted into a packet form. The packets are flexible enough so the gifted chemistry student may be integrated into the chemistry B sections or the packets may be used for a separate honors chemistry class. The flexible sequencing allows the same topics to be studied concurrently with the chemistry B students.

The Future Of Man, The Great Disperser, Elmer Rosauer Jan 1978

The Future Of Man, The Great Disperser, Elmer Rosauer

Iowa Science Teachers Journal

We are living in a world which, depending on personal attitude, may to some degree be materialistic in its value orientation, but most certainly is materials-oriented. (Materials are defined here as substances that become useful to society after some form of processing, e.g., mining, harvesting, refining, or fabrication. This excludes foods, drugs, water, and fossil fuels). There are strong indications that the rate and degree of change in the use of materials by our children -and theirs- will reach a point beyond what we can presently envision. In fact, the current emphasis on precarious supplies of fossil fuels has tended …

Thoughts On Philosophy And Science Curriculum, Marlow Ediger Jan 1978

Thoughts On Philosophy And Science Curriculum, Marlow Ediger

Iowa Science Teachers Journal

Before making curricular decisions, science educators should study diverse schools of philosophy, explore their implications and adopt that philosophy which best meets the needs of the students and community for which the curriculum is designed. The curriculum developed should provide the understanding, skills and attitudes necessary to fulfill the philosophical goals selected. In this paper, four schools of philosophy are explored and their implications to science education are discussed. In all cases, the curriculum designed should promote the recommended principles of the psychology of teaching and learning. Each philosophy proposed assumes an active rather than passive involvement of students.

Creation, Evolution And Public Education, Jack Gerlovich

Iowa Science Teachers Journal

In Iowa and other states, "creationism" has recently been advanced as an alternative to the theory of evolution. Attempts have been made to mandate legislatively "equal time" for creationist concepts in science classrooms, materials and textbooks.


Organizing A Rock And Mineral Club (Part I), Ron Bonstetter Jan 1978

Organizing A Rock And Mineral Club (Part I), Ron Bonstetter

Iowa Science Teachers Journal

This is Part I of a collection of ideas designed to promote the formation of rock and mineral clubs. Such programs are appropriate for interested individuals from upper elementary grades through high school. A broad range of interests and skills are suggested to leave room for the creativity of prospective club advisors. Membership in clubs of this nature provides many opportunities for the development of interests, hobbies and careers. The desire to pursue rock and mineral studies is developed and encouraged by creating an informal setting where individuals can identify and fulfill their interests. A successful club allows its members …

Determining Textbook Readability, George R. Davis Jan 1978

Determining Textbook Readability, George R. Davis

Iowa Science Teachers Journal

Since student success in science is related to reading ability, the selection of a readable text is crucial to classroom instruction. The determination of reading level is probably the single most important factor in textbook selection. If textbooks are unreadable for students, few students will read them and the other reasons for selecting texts will be lost to the reading audience. What determines the reading level of a textbook and how is the reading level of a textbook evaluated? This article discusses the answers to these questions and includes a quick method for reading level determination.

A Teaching Calendar

Iowa Science Teachers Journal

"What can we do today?" is a question voiced by teachers at lesson plan time, by children on rainy days, and others with time on their hands. It used to be difficult to find new and interesting learning activities to fill this time, but with Science Fun, Every Day in Every Way, there are always answers at hand.


Don't Just Talk About The Weather: Investigate It Statistically, Bonnie H. Litwiller, David R. Duncan Jan 1978

Don't Just Talk About The Weather: Investigate It Statistically, Bonnie H. Litwiller, David R. Duncan

Iowa Science Teachers Journal

Scientists frequently wish to determine whether the means of two sets of data differ significantly. A statistical tool for investigating such a question is the "Student t-distribution" so named because its originator, W. S. Gosset, published his findings under the pseudonym "Student". The problem considered in this paper will involve paired variates, that is, the case in which the observations in the first sample of data are paired naturally with those of the second.
