Elementary Physics Applied To Automobile Fuel Economy, Franklin D. Trumpy
Elementary Physics Applied To Automobile Fuel Economy, Franklin D. Trumpy
Iowa Science Teachers Journal
Science educators, especially physics teachers, are frequently confronted with stories about devices and carburetors that permit ordinary cars to get spectacular fuel economy. The claims often exceed 46 kilometers per liter (110 mpg). By applying basic physics as taught at the high school or college freshman level, one can measure the average power output of an automobile at any speed and calculate the maximum possible fuel economy that can be expected.
Consultation
Iowa Science Teachers Journal
The Iowa Academy of Science has set up a Panel of scientists charged with helping communities, parent groups, school boards, administrators, supervisors, and teachers deal with issues arising from science-related controversies, including creation-evolution.

Energy Education Begins With Teacher Education, Mike Geil, Daniel S. Sheldon
Energy Education Begins With Teacher Education, Mike Geil, Daniel S. Sheldon
Iowa Science Teachers Journal
Since 1973 the price of imported crude oil has escalated from $3.00 a barrel (42 gallons) to an average of over $35 a barrel in 1981. Our national bill for imported oil in 1970 was $3 billion, whereas our current expenditure for imported oil exceeds $81 billion. Within this same time period U.S. crude oil imports more than doubled, while import costs increased twenty-seven fold. This astronomic increase in crude oil prices has helped to reduce the value of American dollars abroad and has served to exacerbate recession and inflation at home.
Aaas Resolution On Forced Teaching Of Creationist Beliefs In Public Science Education
Aaas Resolution On Forced Teaching Of Creationist Beliefs In Public Science Education
Iowa Science Teachers Journal
Be it further resolved that the AAAS urges citizens, educational authorities, and legislators to oppose the compulsory inclusion in science education curricula of beliefs that are not amenable to the process of scrutiny, testing, and revision that is indispensable to science.
That All Powerful Textbook In Science Teaching, Robert E. Yager
That All Powerful Textbook In Science Teaching, Robert E. Yager
Iowa Science Teachers Journal
NSF Status Studies emphasize the domination of the textbook in K-12 science classrooms in the U.S. Many lament about the power of the text and seek ways of "getting publishers to produce better ones." Are publishers really the bad guys??
Nsta Report, Robert L. Fisher
Nsta Report, Robert L. Fisher
Iowa Science Teachers Journal
I recently participated in the Board of Directors' meeting of NSTA. I did not see despair, no throwing up of hands to say we have met our match. On the contrary, I saw highly optimistic individuals intent on making lemonade. You will read about these activities in future issues of your journals, but let me take a few minutes to highlight some of the meeting for you.
Games
Iowa Science Teachers Journal
Many science games are created by innovative teachers to spark interest in a science lesson and may later be returned to classrooms as smartly packaged products.
The Newest Goal For Science Education, Robert E. Yager
The Newest Goal For Science Education, Robert E. Yager
Iowa Science Teachers Journal
Four years ago Helgeson and his co-workers at the ERIC/SMEAC center at Ohio State reported that the goals in science education were in a period of major transition (Helgeson, et al., 1977). Three years ago NSTA published a working paper entitled, Science Education: Accomplishments and Needs, in which new goals for the discipline were identified (NSTA, 1978). Recently the NSTA Research Committee completed a research project - one facet of which determined the degree of agreement about such major changes in goals as well as an indication of the nature of new goals (Yager, 1980).

Notes On Creationism
Iowa Science Teachers Journal
In a landmark decision, federal judge Overton struck down a creation science law in Arkansas. Judge Overton concluded that creation science is "simply not science" and that no group may use the organs of government to force its religious beliefs on others.
Position Statement On The Creation/Evolution Controversy From The Iowa Council Of Science Supervisors
Iowa Science Teachers Journal
Because of the insistence that special creation be taught in Iowa science classes as an alternative concept to evolution, we, the Iowa Council of Science Supervisors, as representatives of the science educators in Iowa, make the following statement.
A New Age For The Universe?, Darrel Hoff
A New Age For The Universe?, Darrel Hoff
Iowa Science Teachers Journal
The question of the age of the earth, the solar system, stars galaxies and the whole universe have intrigued man for a long time. The story of Bishop Ussher's use of biblical chronology in the early 1600s to date the creation at 4004 B. C. is the story of the earliest attempt to arrive at an answer to this question. The work of geologists, and physicists during the 1800s called this date into serious question. Investigations based on stratigraphy, salination of the oceans, and heat flow from a cooling earth put the age much greater than Ussher's estimate. Although these …
Comets

What science teacher from grades 5-9 hasn't wanted to show students that the study of science has many career opportunities for both boys and girls?
A Fable For Everyone
Iowa Science Teachers Journal
This story is about four people: Everybody, Somebody, Anybody, and Nobody. There was an important job to be done and Everybody was asked to do it.
How Would You Prove The Earth Is Round?, Darrell D. Young
How Would You Prove The Earth Is Round?, Darrell D. Young
Iowa Science Teachers Journal
In this day of the Space Age, everyone knows that the earth is round. One merely has to look at a photograph taken from either the moon or an orbiting space satellite to prove the point. But suppose that you do not have a photograph handy or suppose that your viewer refuses to believe that the photo is real. Of course it is rather unlikely that the latter event would occur, but without such a visual aid how would you prove that the earth is round?
Flame Tests
Iowa Science Teachers Journal
Problems associated with flame tests include, (1) sodium contamination producing an overwhelming yellow flame, (2) the transient nature of the flame and (3) the hazard of concentrated HCl. The following techniques improve flame tests.

The Role Of The Laboratory In High School Physics, Hank Biere
The Role Of The Laboratory In High School Physics, Hank Biere
Iowa Science Teachers Journal
I'm sure many articles have been written on the role or use of the laboratory in high school physics. So many, in fact, that I'm not sure I can add much of anything that is really new and unique. In spite of the fact that during the last 10 to 12 years we've become very much aware of writing objectives (behavioral type), we've probably not given much thought to objectives of the lab. In some cases we come to a certain place in the book and it's time to do a lab; so we do it without much thought as …

The Tiger Salamander, Michael J. Lannoo
The Tiger Salamander, Michael J. Lannoo
Iowa Science Teachers Journal
Tiger salamanders are harmless members of the Class Amphibia which easily lend themselves to observation and experimentation. As the name amphibian implies, these salamanders have two life forms, an aquatic larval stage and a terrestrial adult stage. Both forms are common and widespread throughout Iowa, yet adults, being terrestrial and less seasonal, are encountered more frequently than the larvae.
