The Abo's Of Blood Types, Willard F. Hollander, Wilmer J. Miller

Iowa Science Teachers Journal

For high school age students the blood types can be a useful introduction to heredity. It has been shown, for example, that if both parents are type O, their children must all be type O: it is recessive to A and to B.

Thanks, I Needed That!, Stanley D. Whelchel

Iowa Science Teachers Journal

Each year, when high school students register for their next year's schedule of classes, the guidance counselors and teachers of science and mathematics hear the statement, "I don't need science or mathematics for what I plan to do after I graduate." It seems almost impossible to change their minds. One usually says, "You will need it when you get to college or to technical school." But this statement usually falls upon deaf ears because students have made up their minds that in the fields of work to which they aspire they will not need any additional mathematics or science. Besides, …

Mobile Career Exploration, Steve Halstead

Iowa Science Teachers Journal

In 1970, the Des Moines Area Community College (DMACC) began a program on its Ankeny campus known as Career Exploration. The idea was to allow people to explore a career by performing representative work samples. For example, a person exploring Medical Laboratory work would have the opportunity to do blood typing, prepare slides, do urinalysis, and prepare smear cultures. These experiences coupled with information about training requirements, job prospects, and salaries, provided a background on which a career decision could be based.

A Checklist In Science Education For Evaluating Student Teaching, James J. Hungerford

Iowa Science Teachers Journal

Have you noticed how little some cooperating teachers let their student teachers do? If "learning is by doing," a lot of student teachers aren't learning very much. I've seen student teachers teach only one or two weeks out of nine. Student teachers and supervisors should have a common checklist of activities that they can include as part of the student teaching experience. This may help the teacher who lectures frequently to do something besides talk. The aim would_ be mutual improvement and increased competence.

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.

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.

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 …

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 …

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 …

The Integration Of Self-Descriptions And Descriptions By Outside References In The Evaluation Of Job Applicants, Jeanette M. Dolezal, Irwin P. Levin

Proceedings of the Iowa Academy of Science

A study was conducted to determine how different types of information are combined to arrive at evaluations of hypothetical job applicants. Sixty subjects were asked to evaluate nine applicants for the position of elementary school principal. The information describing each applicant included a letter of self-description and from one to three letters from outside references. Results can be summarized as follows: (1) evaluative ratings of job applicants were directly related to the value (level of favorability) of the information contained in the outside letters of reference and the value of the information contained in the self-description; (2) the greater the …

Assessing Laboratory Instruction In Biology, Melton E. Golmon

Iowa Science Teachers Journal

Biology curriculum developments of the last decade have emphasized the importance of laboratory instruction in the learning environment. Not only do most students enjoy laboratory work but it provides them with an opportunity to make first hand observations, manipulate equipment, collect data, organize data, and draw their own conclusions concerning this information. One teaching strategy for laboratory instruction developed by the Biological Sciences Curriculum Study (BSCS) creates a setting in which a question can be formulated that may be answered as a result of laboratory work. Special instruction is given for specific laboratory techniques and skills when necessary but major …

Team Orientation In The Chemistry Laboratory, David N. West

Iowa Science Teachers Journal

The importance of laboratory experience for students is widely accepted by chemistry educators and usually includes the following behavioral objectives: 1. Training in the scientific method. 2. Developing skills with laboratory apparatus. 3. Learning and applying chemical theory. 4. Communicating laboratory results. It is the opinion of this writer that through a team orientation approach to instruction other behavioral objectives can be attained in laboratory situations that are also useful to students pursuing professional careers in chemistry.

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.

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.

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.

Earth Incorporated, Robert Rienow, Leona Train Rienow
