A Computer Assisted Environmental Education Resource Program, Sara K. Smerud, Gary Thomas, Tim Keenan, Dale Nimrod
Iowa Science Teachers Journal
Northeast Iowa is an exceptionally beautiful and unique region. Environmental education in the schools and communities of this area is a vital factor in enabling citizens to take a reasoned approach to the conservation and management of this region. Two observations precipitated the action which resulted in the project described in this paper. The first was that the local resources were vulnerable to being utilized in a potentially harmful manner and secondly, teachers did not seem to be taking full advantage of their local resources in their classroom instruction.

Exotic Food From Fermented Milk, Robert C. Goss
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.

The Christmas Experiment, Glen Loveridge
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
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, …

Assessing Laboratory Instruction In Biology, Melton E. Golmon
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 …

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
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
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 Academy Of Science Celebrates Centennial Anniversary Of Founding, Robert W. Hanson
Iowa Academy Of Science Celebrates Centennial Anniversary Of Founding, Robert W. Hanson
Iowa Science Teachers Journal
April 17-19, 1975, marks the observance of an important historical event in Iowa, for it was in 1875 that Charles E. Bessey and a handful of scientists and medical men conceived the original Iowa Academy of Science. One hundred years have produced fantastic changes in life in Iowa, and the Academy of today has almost forgotten its heritage. It has grown from a small fellowship of men dedicated to furthering scientific work in Iowa to 1,400 members-a sizable cross section of the entire scientific community representing pure and applied research, conservation activity, engineering, economics and all levels of education and …
On The Feasibility Of Coal-Driven Power Stations, O. R. Frisch
On The Feasibility Of Coal-Driven Power Stations, O. R. Frisch
Iowa Science Teachers Journal
The recent discovery of coal (black, fossilized plant remains) in a number of places offers an interesting alternative to the production of power from fission. Some of the places where coal has been found show indeed signs of previous exploitation by prehistoric men, who, however, probably used it for jewels and to blacken their faces at religious ceremonies. The power potentials depend on the fact that coal can be readily oxidized, with the production of a high temperature and an energy of about 0.0000001 megawatt days per gram. That is, of course, very little, but large amounts of coal (perhaps …

Notes On Science Teaching - 1, Sherman Lundy
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
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 …
