Module 9: Analysis Of Physics Concepts, Francis P. Collea, Robert Fuller, Robert Karplus, Lester G. Paldy, John W. Renner

Physics Teaching and the Development of Reasoning: Workshop Materials

Most physics teachers think about their courses in terms of topics covered, concepts explained, and principles applied. Our effort in this workshop has been to call your attention to another impartant dimension of physics teaching: your students' patterns of reasoning. By this time, you have probably concluded that most physics courses are addressed primarily to students who can use formal reasoning patterns with ease, and we would agree with that. Yet there are also the students who use formal reasoning patterns only with difficulty and in limited areas. To help you analyze course content and present it in a way …

Exotic Food From Fermented Milk, Robert C. Goss

Iowa Science Teachers Journal

Whether prepared or bought at the market, yogurt is a dairy product made from milk -- cow, mare, sow, goat, buffalo, etc. Bacteria cultures of Streptococcus thermophilus and Lactobacillus bulgaricus are added to the milk with the result that the milk sugar is split into lactic acid. The casein, lactalbumin and milk proteins are broken down into peptones and amino acids. Finished yogurt has about 200,000,000 bacteria per ml and is rich in the vitamin B complex. Yogurt making is a manifestation of microbial ecology.

Dirty Books

Iowa Science Teachers Journal

School books are notorious carriers of potentially dangerous bacteria. Books that are handed on to children in one class to their successors in the next year pose a considerable health hazard, according to the Institute for Educational Media, Frankfurt, Germany.

Mit To Study Nonconventional Protein Sources

The Christmas Experiment, Glen Loveridge

Iowa Science Teachers Journal

What will you be doing with your class the last periods before the Christmas break? If you have a strong digestive system, try this production of foamy peanut brittle. It was first suggested in the Journal of Chemical Education, August 1972, by Richard C. Adams of Pleasant Hill High School, Pleasant Hill, Oregon 97401. However, the outline given was for a 90-minute lab, and I have modified it for a 40-minute lab. I have found that with my modifications, all of my students - good or poor - can do this lab.

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, …

Coming Astronomical Events, Darrel Hoff

Iowa Science Teachers Journal

This fall skies will be dominated by the planet Jupiter. During October and November Jupiter will be rising near sunset and will be visible nearly all night. An interesting activity for beginning students of astronomy is to identify Jupiter's four brightest moons.

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 …
