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

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.

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

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 …

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.
Seeing Sound, Sondra Waltz
Seeing Sound, Sondra Waltz
Iowa Science Teachers Journal
Making sound visible is a useful activity in teaching students the concepts that sound is caused by vibrating objects and that different sounds are caused by different types of vibration. This particular activity makes it possible to see the sounds produced by observing a vibrating, metal plate. As the plate produces sound it vibrates violently in some areas and not at all in other regions. If a small amount of very fine sand or poppy seed is sprinkled on the plate as it vibrates, the seeds will move to areas where vibration is minimal and form distinct distributional patterns on …
Nsta Pit Stop
Iowa Science Teachers Journal
You'll be able to make a pit stop at this year's area convention in Indianapolis on October 23-25. While we hope there's no need for "major repairs" you'll be able to refuel your tank of teaching ideas as you see and hear what others are doing.

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.

Food From Newspaper
Iowa Science Teachers Journal
Cellulose is the most abundant organic material which can be used as a source of food, fuel and chemicals. The net world-wide production of cellulose is estimated at one hundred billion tons per year. This is approximately 150 lbs. of cellulose per day for each and every one of the earth's 3.9 billion people. The energy to produce this vast quantity of cellulose comes from the sun and is fixed by photosynthesis.
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.

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.

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 …
