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," …

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 …

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 Inexpensive And Collapsible Plant Growth Frame, Al Janulaw, Mat Keller

Iowa Science Teachers Journal

This plant growth frame was designed for use in second and fourth grade classrooms as a part of National Science Foundation Grant TEI 8751303, Materials and Assistance for Science Teaching (MAST). We needed frames that were relatively inexpensive, could be made from locally available materials and would be easy to store when not in use. The frame is made from PVC pipe. The light source is a 48-inch, two-bulb shop light, using ordinary fluorescent tubes. A plug-in timer is used to control the time of illumination. Our first models included a plywood base, but some teachers have omitted this. The …

Science Notes - Student Opportunities To Name Features On Venus

Iowa Science Teachers Journal

When astronomers and planetary geologists first see a new terrain feature on Venus, they typically assign both a descriptive term (like "crater," "corona" or "mons") as well as a particular name. Since Venus was the Roman goddess of love, scientists have decided to name its features after famous females throughout history. Most of the large features, like the Venusian land masses Aphrodite Terra and Ishtar Terra, have been named for love goddesses from other cultures. Although names for many of the craters have already been proposed, the International Astronomical Union, which is the sole authority for assigning names to celestial …

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.
