It is now understood that some chemicals have an extraordinary high potential for causing cancer in humans. Fourteen such chemicals are classified on the zero exposure tolerance list. Fourteen such chemicals are classified on the zero exposure tolerance list. The names of these fourteen chemicals are listed below.
Organizing A Rock And Mineral Club (Part Ii), Ron Bonstetter
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.

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

Chameleons In The Classroom, David Fagle, Nancy Walden
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.

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

A Philosophical Approach To The History Of Microbiology, James Slock
A Philosophical Approach To The History Of Microbiology, James Slock
Iowa Science Teachers Journal
In a previous article, science and how science operates was discussed from a philosophical point of view. In this article, the history of the Germ Theory of Disease (and hence a large part of the history of microbiology) is discussed from the philosophical perspective presented in the first article. The history presented in this article is not intended to be definitive but rather to view the history of the Germ Theory of Disease from a different perspective.
A Chemistry Tip

In the CHEMS laboratory reaction of hydrochloric acid with Mg ribbon, addition of some food coloring to the acid solution makes gas volume easier to read.
Pcb's, Erwin Richter
Pcb's, Erwin Richter
Iowa Science Teachers Journal
PCBs, or polychlorinated biphenyls, is a general name applied to compounds consisting of two benzene rings joined together, with several to all of the remaining hydrogen atoms substituted with chlorine. Because of this, formulations of PCB's vary in the percentage of chlorine with the sample taken.

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

Float, Sink, Think!, Timothy Cooney
Iowa Science Teachers Journal
The following is a typical question asked at the end of physics units dealing with buoyancy: "A barge loaded with scrap iron is in a canal lock. The captain orders his crew to dump all of the scrap iron overboard. What happens to the water level in the lock?" I have asked this type of question to both high school and college physics students. Of course, answers are given which predict an increased, a decreased , or an unchanged water level.
