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 …

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).

Science Notes - Book News : "Science And Creation: Geological, Theological And Educational Perspectives", Robert W. Hanson

Iowa Science Teachers Journal

During the past few years the scientific community at large and the education community in particular have awakened to the public's concern about restoring traditional values in American society. The theory of evolution is seen by many Fundamentalists as responsible for the destruction of these values. Thus, in an attempt to restore this value system, a substantial part of the public has supported the movement to teach "creation science," which purports to show that a literal interpretation of the Genesis account of origins, including the notion that the universe is only a few thousand years old, can be supported scientifically.

Mathematics And Science Education Pays Off, Jack A. Gerlovich

Iowa Science Teachers Journal

2. mathematics

Many states have implemented legislation in an effort to improve science and mathematics education in our nation's schools. Last year; the Iowa General Assembly enacted House File #532. The bill established several innovative state programs designed to encourage greater emphasis in the study of mathematics and science. Three of these programs were to be administered by the Iowa College Aid Commission, and had direct influence on K-12 science courses, teachers, and prospective teachers.

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.

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.
