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 …

Consumer Science: A Viewpoint, Donald J. Schmidt Jan 1978

Consumer Science: A Viewpoint, Donald J. Schmidt

Iowa Science Teachers Journal

As a member of the Iowa Academy of Science and a former Iowa teacher, I know that science teachers in Iowa are constantly striving to make their classes more interesting and meaningful to students. I would like to share with you some ideas generated by a group of twenty-three secondary school science teachers at Fitchburg State College in a summer workshop dealing with consumer science education.

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 …

The Cecropia: An Incredible Eating Machine, Linda B. Hoffman Jan 1978

The Cecropia: An Incredible Eating Machine, Linda B. Hoffman

Iowa Science Teachers Journal

One of Iowa's most dramatic, native insects is the cecropia moth, Hyalophora cecropia. The larvae of this large, woodland moth feed on the leaves of native trees such as birch, maple, ash, willow, elm, apple and wild cherry (Swan and Papp, 1972). The adults are most prevalent in Iowa in late spring and early summer. In late summer the most prevalent stage is represented by large, distinctive caterpillars. In late fall, the dominant stage is the spindle-shaped, pupal cocoons found attached to the twigs of deciduous trees or in litter at base of trees.

Human Physiology And Anatomy: For All Students At The Same Time, Irene M. Edgar Jan 1978

Human Physiology And Anatomy: For All Students At The Same Time, Irene M. Edgar

Iowa Science Teachers Journal

How should a specialized science course in high school be taught? Should it be treated as a career education course or as a general survey course? Should it follow traditional methods or should it be individualized? These questions were explored in teaching a two semester course in Human Physiology and Anatomy at Dubuque Senior High School. This course attracts students who plan a post-high school career in health oriented fields, as well as students interested in additional exploratory study that goes beyond general biology. In addition, others enroll for needed science credits. As a result, the course must service a …

Facilitating Inductive Reasoning In The Elementary Classroom: A Novel Approach, Gregory Stefanich Jan 1978

Facilitating Inductive Reasoning In The Elementary Classroom: A Novel Approach, Gregory Stefanich

Iowa Science Teachers Journal

Educational experiences often tend to leave children with the feeling that there is only one pathway to success. At an early age children are taught to perceive in a way consistent with an adult viewpoint. This is accomplished through repetitive conditioning during which children are taught that an adult, who possesses authority, perceives correctly. As a result, children begin to think in "acceptable" traditional modes and base their behavior on the standards and expectations of others.

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 …

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.

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

Iowa Science Teachers Journal

Rock and Mineral Clubs (Part I) provided ideas for the initial organization of rock and mineral clubs. In order for club members to develop this avocation to its fullest, a number of basic skills have to be mastered and some equipment must be acquired. The basic skills include rock, mineral and fossil identification and collection, as well as skills in lapidary such as tumbling, cutting, shaping and mounting gemstones.

Decapods Of Iowa (Part I), Gary Phillips Jan 1978

Decapods Of Iowa (Part I), Gary Phillips

Iowa Science Teachers Journal

Decapods are a fascinating group of animals which inhabit most aquatic environments in Iowa. As they are secretive, their habits are not well known. However, they play an important role in Iowa's aquatic communities and are worthy of more attention by biology teachers and their students. Decapods are members of the class Crustacea, a group of arthropods with gills and heavy, crust-like exoskeletons. Crustaceans include such diverse forms as the microscopic water fleas and copepods, the larger sowbugs and amphipods and the more familiar decapods such as crayfish and river shrimp. All decapods have ten walking legs. In Iowa, decapods …

Iowa's Diatoms: Part I (Collection), James Hungerford Jan 1978

Iowa's Diatoms: Part I (Collection), James Hungerford

Iowa Science Teachers Journal

The three dominant groups of algae found in Iowa are Chlorophyta (green algae), Cyanophyta (blue-green algae), and Chrysophyta (golden-brown algae). The golden-brown algae is composed of a variety of species called diatoms. This is the first in a series of articles on Iowa diatoms. Unlike most other plant species which have cell walls of cellulose, diatoms have siliceous cell walls constructed of two overlapping valves which fit together like the lids of Petri dishes. These walls are ornamented with fine ridges, lines and pores that are characteristic for each species. Although the contents of the cells decompose readily the cell …

The Endangered And Uncommon Amphibians And Reptiles Of Iowa - Turtles, James L. Christiansen, Russell R. Burken Jan 1978

The Endangered And Uncommon Amphibians And Reptiles Of Iowa - Turtles, James L. Christiansen, Russell R. Burken

Iowa Science Teachers Journal

Iowa has 23 amphibian and reptilian species whose known populations or ranges within the state are so small as to justify their inclusion in the state's endangered or threatened list (Roosa, 1977). This paper is intended to inform the Iowa scientific teaching community of the plight of these species and to recruit help in gathering information relative to their distribution. Most of the information presented here has been accumulated by Christiansen and Bailey (manuscripts in preparation or in press) in their work on the amphibians and reptiles of Iowa.
