Science Notes - Natural History Potpourri Workshops

Iowa Science Teachers Journal

27. natural

Natural History workshops are scheduled at the Conservation Education Center (Springbrook) for the weeks of June 14-19 and 21-26, 1992. The potpourri of topics includes: birds, trees, rocks, prairie plants and pond life. The week-long sessions will include field trips, lecture/discussions, slide talks and participation in activities which link the content topics to classroom activities. Highlights of previous programs have included canoeing the slough for observations of yellow-headed blackbirds, making T-shirt designs with Cherokee leaf pounding, a trip through a virgin prairie and the "Potpourri Picnic."

The Wasberg Effect, Thomas H. Vertrees

Iowa Science Teachers Journal

Working on demonstrations that were considered useful and graphic teaching tools received considerable energy from the participants at the North West Workshop for Teachers of Chemistry (NWW) under the direction of Dr. Glenn Crosby at Washington State University in 1987. Some new demonstrations were developed, but most of the effort was spent dealing with traditional and published successful teaching aids to make the directions uniform and clear, even to teachers without extensive chemistry training, and to perfect directions that would work every time.

Paper Airplanes: A Critical Thinking Model, William Bluhm, Martha M. Kronholm

Iowa Science Teachers Journal

What upper elementary school teacher during his or her career hasn't had to deal with the occasional illicit flight of a paper airplane? Children show an interest in airplanes--from the paper variety to model planes to the real thing. From an educational standpoint, it would seem beneficial to make use of this interest. One possibility within the arena of the science class would be to use the paper airplane as a vehicle (no pun intended) for hands-on activities utilizing such sophisticated critical thinking skills as controlling variables, hypothesizing and experimenting.

Science Notes - New Hands-On Elementary Science Program

Iowa Science Teachers Journal

The National Science Resources Center has introduced the first three units of its new hands-on elementary science program. "Plant Growth and Development," "Electric Circuits" and "Microworlds" were demonstrated at a March 6 news conference in Washington, DC. The units are part of NSRC's elementary science curriculum project, "Science and Technology for Children" (STC). The project is based on the principle that children learn science by doing science.

Science Notes - Review: Simearth, Software For Planet Management, James J. Hungerford

Iowa Science Teachers Journal

Recently, I had the opportunity to review a computer program produced by MAXIS called "SimEarth." The program simulates many different aspects of a planet, including climate, evolution, atmospheric composition and civilization. The user designs, modifies, manages and nurtures a planet from creation through the formation of oceans, appearance of life, evolution and development of intelligence and a level of technology that can look beyond the planet to space. Inspired by James Lovelock's GAIA hypothesis, Sim Earth simulates the Earth as a living organism.

Two Simple Exponential Decay Experiments, John W. Zwart, Carl Fictorie, Michael Hubers

Iowa Science Teachers Journal

When trying to teach a wide variety of experimental analysis techniques on a tight budget, teachers often have difficulty finding hands-on experiments which illustrate exponential decay and provide for the teaching of semi-log plotting skills. The authors have developed the following inexpensive and easy-to-implement experiments to meet that need.

The Iowa Aea Middle School Science Project - Sleds, Dean Hartman, Rollin Bannow

Iowa Science Teachers Journal

A resource of over 300 science activities is now available to Iowa science teachers from the Iowa AEA Middle School Science Project electronic bulletin board. It is the result of a report from a 1984 task force commissioned by the Iowa Department of Education to assess the needs of science education in Iowa. The task force identified the grades four through nine as those with the greatest need. Specifically identified was a need for user-friendly teaching materials that emphasized a "hands-on/minds-on" approach to science. Too large a portion of the science taught in these grades was based primarily on a …

Temperature Trends In Iowa, Laurent Hodges

Iowa Science Teachers Journal

With all the discussion about possible global warming, many people have wondered: What is the historical trend in Iowa's temperatures? This can be answered reasonably well for the past century. Temperature records since 1873 have been compiled by the State Climatological Office and its predecessors (National Climatic Center, 1990). For many years the State Climatologist published the average annual temperatures for the state as a whole, but that practice ceased in the early 1950s. Consequently, I have gone back over the records of the last 11 decades (from 1880 to 1989) and computed an average annual temperature for each year …
