Science Notes - Book News : Geology Of Iowa: Over Two Billion Years Of Change

Iowa Science Teachers Journal

In Geology of Iowa: Over Two Billion Years of Change, author Wayne I. Anderson presents a chronological account of the rock formations that underlie the farmland and cities of Iowa. Recently published by the Iowa State University Press, Geology of Iowa begins with a description of the geologic setting of the state in the Stable Interior; a region of generally flat-lying sedimentary rocks that show little deformation. Anderson comments, "At any one location in Iowa, the rocks typically appear to be horizontal - as flat as a pancake."

Letter To The Editor - More Support For Saturday Classes, Edward M. Vaughan

Iowa Science Teachers Journal

The letter from Richard Wilson in the Winter '83- 84 ISTJ not only gives me an opportunity to endorse the scheduling of science/math classes on Saturdays and during the evenings with part-time teachers but also as another ex-math/science teacher, to voice opinions in several other aspects of teaching. In the '50's at St. Ambrose College we initiated Saturday Science Seminars for secondary school students which were highly successful.

Writing And Elementary Science: A Winning Combination, Bonnie Knutson

Iowa Science Teachers Journal

Most educators today believe that writing has a significant place in the curriculum. More importantly; many teachers agree that writing instruction should be a school-wide effort. In one study; 80 percent of the English teachers, 60 percent of the social studies teachers and 60 percent of the science teachers agreed that it was a responsibility that should be shared by both English and content area teachers (Tighe and Koziol, 1982).

The Word Processor: A Tool Towards Improving Every High School Research Project, George E. O'Brien

Iowa Science Teachers Journal

Two important education phenomena are happening concurrently across the state of Iowa. First, it should be no surprise that the number of computers and computer science course offerings in high school is steadily increasing while the number of microcomputers in students' homes is also becoming greater. These factors have led to an overall increase in the number of high school students interacting with computers across the state. Second, feedback received from a variety of sources including state and regional science teachers' meetings, talented and gifted conferences (TAG), student science fair and symposia competitions and high school in-service visitations by Area …

Rock And Mineral Collecting In Iowa, Joseph H. Brown

Iowa Science Teachers Journal

The enthusiastic collector of rocks and minerals enjoys and practices a most interesting hobby. Nature has provided a free source of materials in many different localities, and the Midwest is no exception to this bounty. Success in finding a rare rock or mineral is limited only by the skill and perseverance of the collector. The natural beauty of many mineral, rock, and fossil specimens makes finding them a stirring experience. The value and rarity of these examples of nature's wealth makes the search for them a stimulating and profitable adventure.

A Primary View Of Science Education, Marjorie A. Switz

Iowa Science Teachers Journal

The primary teacher has a fundamental task in science education. The responsibility today is greater than ever to perform the science education task carefully, with specific curriculum goals clearly and sequentially mapped out. Primary teachers work with very impressionable material - young students. They lay the foundation of formal learning. No structure is sound or lasting if it has a weak or unsound foundation. The same is true of the education of young students and their introduction to organized science processes and knowledge. The foundation must be laid with care and strength of purpose. Primary teachers have the fascinating task …

A Biological Light Meter, Dennis Sievers

Iowa Science Teachers Journal

High school experimentation during the study of botany generally includes observing photobiological processes. These might include photosynthesis, phototrophism and photoperiodism. Experiments with these processes often involve exposing a plant or plant tissue to a light source covered with a piece of colored cellophane or plastic. Measurement of the light intensity at a specific wave length is often necessary.

The Feeding Behavior Of The Giant Waterbug, Stephen W. Ziser

Iowa Science Teachers Journal

Ethology, the study of animal behavior; is a branch of biology too often overlooked in beginning biology courses. This is unfortunate since studying the behavior of living animals not only captures the interest and imagination of students more easily than other kinds of laboratory exercises but can also help to develop the skills of observation and description so fundamental to the art of science.

Demonstration Model Of An Organic Catalyst, Dennis Sievers

Iowa Science Teachers Journal

Introductory high school biology courses generally include a discussion of enzymes. Enzymes, commonly defined as biological catalysts, speed up biochemical reactions and are involved in nearly every biochemical process that occurs in a living organism. Many texts currently being used provide diagrams of enzyme action and a discussion of the "lock and key fit" of enzyme and substrate. Laboratory manuals accompanying these texts frequently indicate the usefulness of the chewed cracker experiment to demonstrate the presence and ·action of salivary amylase. Though this experiment uses an enzyme, it does not always accomplish the desired result - to enable the students …
