Weather Changes And Crop Yields

Iowa Science Teachers Journal

Some scientists, believing that the earth is getting colder, are now predicting the future of world crop production, based on projected temperature changes.

Coal? What's That?

Iowa Science Teachers Journal

In any analysis of the energy resources now available to the United States of America, coal occupies a dominant if not a preeminent position. The very fact that, within the borders of the U.S., there is more energy in the form of coal (more than three trillion tons) than in all of the other combined resources of fossil fuel-petroleum, natural gas, oil shale, and bituminous sandstone-makes coal loom as our most important source of energy for the remaining years of this century, and perhaps for centuries to come.

Notes On Science Teaching - 1, Sherman Lundy

Iowa Science Teachers Journal

Many teachers seem to operate from a partial teaching model that does not adequately relate the various parts to the whole of science education. The current state of affairs is much like that of the six blind men describing an elephant. Each teacher sees in part and formulates a description of science education from that point of view. As a result, teachers often become torn between subject matter; student needs; teaching techniques; administrative, community, and governmental influences; and other concerns, all tending to fragment the approach to science education.

On Appreciating Science

Iowa Science Teachers Journal

The scientific attitudes which should be developed are: An intense curiosity about the world in which we live; A firm understanding that every effect has a cause, and every cause is the effect of a prior cause; A firm belief in truth; Making careful and accurate observations; Weighing all the evidence before drawing a conclusion; Appreciating the debt owed to scientists of the past.

Scientific Instrumentation: It's Older Than You Think

Iowa Science Teachers Journal

If you accidentally walked into the wrong room at a university and found yourself surrounded by balances, glass tubing, Bunsen burners, flasks, beakers and the like, you could safely assume that you had entered a chemistry laboratory. Had the room been filled with timers, force tables, pulleys, oscilloscopes and the like, it might be a physics lab. The tools and instruments a scientist uses betray not only his profession but often his current line of research and the questions he is asking. In the space below a major scientific instrument is described. Read the list slowly and try to identify …

Earth Incorporated, Robert Rienow, Leona Train Rienow

Iowa Science Teachers Journal

"Earth" is a proper name. Do we speak of "the mars," or of "the jupiter," or of "the venus"? Then why "the earth"? It is a degradation of both our thinking and our very special planet.

Science, Schooling, And Society: Toward An Integrated Curriculum, Peter B. Dow

Iowa Science Teachers Journal

Those of us who have participated in the curriculum movement over the past decade have seen a profound change in the orientation of curriculum makers during this period. In the wave of science-based curriculum projects that followed the launching of Sputnik in 1957 there was little explicit attention given to the social purposes of instruction. The emphasis in those years was on the transmission of knowledge in the most economical form through the identification of central ideas, and on the invention of pedagogical techniques that supported and reinforced the child's natural curiosity and desire to learn. One of the most …

A Pound Of Prevention: Teacher's Guide To Behavior Problems, James L. Hymes Jr.

Iowa Science Teachers Journal

They come to school with one big urge: to be liked by the other children, to find a place they can fit in. It is not a question of being in or out; IN they have to be. Children have only one choice: to be in on something good or to be in on something bad. No child can stand to be ignored. It feels better to be noticed for swearing, or for mistakes, or for forgetting, or for silliness, than not to be noticed at all.

Length Of Life: A Study In Demography, James J. Hungerford

Iowa Science Teachers Journal

Your local cemetery may be an excellent field trip site. For example, I use wooded Timber Creek Cemetery for the following study. Each student collects data from nine different headstones and also plots the location of the same grave markers on a map. The student records the name and sex of the deceased, epitaph and/ or heritage, cause of death if recorded, the condition of the headstone, the kind of rock it is, and anything unique about it.

Do We Misuse Animals In School Science Projects?, John A. Hoyt

Iowa Science Teachers Journal

A 17-year-old Iowa girl won a trip to the 1974 International Science and Engineering Fair by grafting skin onto 12 mice in the basement of her home after only talking with a veterinarian. One mouse died, one sloughed off the graft, and the others were killed by the student with an overdose of ether. A 15-year-old Kentucky boy won a trip to the same fair by trapping three squirrels in a park, confining them to cages in his basement, and giving them electric shocks over a period of several months to learn if they would respond to visual tests. This …

Trends In Secondary Science Enrollments In Iowa, Gary Downs

Iowa Science Teachers Journal

Enrollment data were collected from the district administration for the five reported years starting with the 1968-69 school year. The data for the 1973-74 school year were collected at the school level. Collection at the school level should provide a more representative data bank for the academic programs. All the science offerings were grouped into the following seven categories: biology, chemistry, earth science, enrichment science, general science, physical science, and physics. It is interesting to note that in the 1968-69 data collection only 19 different courses were reported. In the succeeding years, 25, 56, 71, 74, and 96 were reported …

Student Philosophy In Science Class, Owen Primavera

Iowa Science Teachers Journal

As a science teacher I know that facts are vital parts of teaching chemistry or biology, and that the better students understand chemical and biological systems the better they will understand how organisms function. But more than facts seems to be needed to teach ecology.

The Need For Nitrogen, Ralph Hardy

Iowa Science Teachers Journal

Exacting a toll of death and suffering, the world's food supply trails population growth. To help bridge this gap, scientists are probing a uniquely-talented group of bacteria. This is Stuart Finley for Men and Molecules, presented by the American Chemical Society. Today, a report on the progress and promise of nitrogen fixation.
