Editor's Corner - Beyond Environmental Awareness, Jonna M. Higgins Jan 1991

Editor's Corner - Beyond Environmental Awareness, Jonna M. Higgins

Iowa Science Teachers Journal

By now, most educated people must be aware that we are sitting on an environmental time bomb. Being aware of these problems is like knowing that a house is on fire somewhere in our city: we feel vaguely sad for those whose home is being destroyed, but the situation doesn't urgently demand our attention. We feel sure that someone else is taking care of the problem. Unfortunately, everyone seems to view our environmental difficulties as a fire in the distance - someone else's problem.

Mystery Powders A La The Learning Cycle, William Bluhm Jan 1991

Mystery Powders A La The Learning Cycle, William Bluhm

Iowa Science Teachers Journal

Even as the 1990s seem to be ushering in a new wave of "hands - on" science, one cannot help but look back to the late 1960s when a previous wave of experiential science programs was crashing ashore. Two programs notable among those spawned during the late 1960s and early 1970s were Elementary Science Study (ESS) and the Science Curriculum Improvement Study (SCIS). ESS units, originally a group of fifty-six independent units covering topics from the physical, biological and earth sciences for K-9, incorporated an instructional strategy called "messing around." "Messing around," which took place during the early portion of …


Earthworm Day, Kenneth W. Thompson, Deborah K. Thompson Jan 1991

Earthworm Day, Kenneth W. Thompson, Deborah K. Thompson

Iowa Science Teachers Journal

Using live animals in the elementary science classroom fosters enthusiasm and encourages curiosity. The earthworms discussed in this article, commonly called night crawlers, are easy to find in Iowa in moist garden soil or around lawns. Earthworms are often used as fishing bait and, because of this, are readily available at reasonable prices from commercial bait dealers or backyard entrepreneurs. Besides their availability and low cost, earthworms are relatively hardy and easily handled by elementary students. For these reasons, and because of the very important role earthworms play in the environment, they were selected to be the focus of the …


Astronomy Resources, Thomas Hockey Jan 1991

Astronomy Resources, Thomas Hockey

Iowa Science Teachers Journal

A visual survey of all nine major planets is a standard way of beginning a series of lessons in solar-system astronomy. One of the pitfalls of such a slide program is that the different worlds of the Solar System tend to blur together in students' minds. To separate my topics, I have prepared a set of title slides. The street sign motif underscores the theme of "touring" the Solar System.


A Survey Of School/Business Partnerships, Edward Bryan Roberts Jan 1991

A Survey Of School/Business Partnerships, Edward Bryan Roberts

Iowa Science Teachers Journal

Good science teachers enrich their classes in a variety of ways with creative use of media and hands-on laboratory exercises. They also use community resources successfully to stimulate student interest (traditionally in the form of field trips and guest speakers). An extension of this idea is for educators to create an alliance or partnership with a business or other organization. The goals of the survey reported here were to discover the thoughts of people with an interest in partnerships or alliances and for the Iowa Alliance for Science to use this information to help facilitate partnerships.

State Indicators In Science And Mathematics Education: A Comparison Of Iowa And The United States, John Ramsey

Iowa Science Teachers Journal

The first state-by-state data of key indicators of the condition of science and mathematics in schools has been issued in a report from the Council of Chief State School Officers (CCSSO). This report, State Indicators of Science and Mathematics Education, is supported by a grant from the National Science Foundation. The project identified two objectives: (1) to improve the quality and usefulness of data on science and mathematics education so that state policy makers and program managers can make more informed decisions; and (2) to define and implement a set of indicators, national and state level analyses of progress in …


An Epa Water Quality Test For Middle Schools: Filterable Residue, Charles Englund Jan 1991

An Epa Water Quality Test For Middle Schools: Filterable Residue, Charles Englund

Iowa Science Teachers Journal

One part of the Clean Water Act requires monitoring the quantity of suspended particles in water. Water is tested before and after being used by industries. The quantity of suspended particles is measured by weighing the residue filtered from the water. This experiment, appropriate for use with upper elementary and junior high students, provides an opportunity to participate in a water quality test used by the Environmental Protection Agency (EPA). Minimal equipment is needed; no hazardous material is involved and the experiment gives interesting results on local water. The results are recorded in milligrams per liter, which is parts per …

Microscale Cartesian Diver Activities, John J. Mauch Jan 1991

Microscale Cartesian Diver Activities, John J. Mauch

Iowa Science Teachers Journal

Because air has weight, it exerts pressure. The air in a room can weigh as much as 100 kilograms, which is the weight of a large person. Air can also be compressed into small containers, such as those used by underwater divers. Teachers can construct several toys called Cartesian divers which will rise and fall exactly as a diving bell does. The toys are called "Cartesian" because the principle of moving diving machines by air pressure was first explained by Rene Descartes, a 16th century mathematician. This exercise is divided up into four parts: "A Cartesian Retriever," "The Cartesian Helicopter," …
