Decapods Of Iowa (Part I), Gary Phillips
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 …

The Metric "Indy", Janice Brandt, Daniel Yates
Iowa Science Teachers Journal
The following is a game designed to provide practice with basic metric units of linear measurement. Students turn up cards to advance their "race cars" along a centimeter track. The race cars can be made of white cuisenaire rods, centicubes or similar objects. This game is suitable for grades 3-8.
Entry Into Elementary Science Through Live Animals, Stanley L. Weinberg
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.
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 …

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

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

Float, Sink, Think!, Timothy Cooney

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.

A Philosophical Approach To The Meaning Of Science, James Slock
A Philosophical Approach To The Meaning Of Science, James Slock
Iowa Science Teachers Journal
It would seem to be a rat her simple matter to define what science is and how it operates. After all, a good portion of our high school and college careers have been spent in science classrooms and laboratories. Possible answers might be that science is an organized body of knowledge and that it operates by discovering the truth about nature through the use of scientific method. It seems equally simple to visualize science as a massive pile of bricks with each scientist adding a new brick each time he discovers a new fact or invents a new theory. Further, …
