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

The Endangered And Uncommon Amphibians And Reptiles Of Iowa - Introduction, 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.

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

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.

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.

Chameleons In The Classroom, David Fagle, Nancy Walden Jan 1978

Chameleons In The Classroom, David Fagle, Nancy Walden

Iowa Science Teachers Journal

What can you get at a pet shop that will change its color and your science teaching? You can get Anolis carolinensis, a unique and interesting reptile that has become a commonplace object of study in many progressive science classrooms. Anolis carolinensis, the American chameleon is not a "true" chameleon. "True" chameleons exhibit more dramatic color changes, but children are charmed and intrigued by the behavior and color changes exhibited by this American reptile.


Learning To Write Chemical Equations Is Something Else, Robert W. Hanson Jan 1978

Learning To Write Chemical Equations Is Something Else, Robert W. Hanson

Iowa Science Teachers Journal

Chemical equations are the stock-in-trade for much of what is expected of students in the first semester of college chemistry. Knowing how to read them, balance them, and interpret them in terms of molar ratios or stoichiometry is one thing; being able to write them from chemical knowledge or from experimental observations is another.

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 …

Teaching Both Brains, Roy Unruh Jan 1978

Teaching Both Brains, Roy Unruh

Iowa Science Teachers Journal

In the advanced vertebrates, including man, the two large hemispheres of the cerebrum of the brain serve as centers of perception, of voluntary motion, and of the higher mental faculties such as thought and memory. The two hemispheres are connected by several bands of nerve tissue the major tissue being the corpus callosum. The two hemispheres control the motor and sensory responses of the opposite sides of the body. Some hemispheric differences in function were reported as early as 1861 when Dr. Paul Broca observed that patients with lesions on their left cerebral hemispheres were more likely to suffer loss …
