Quick take on the wide, wide world of geometry
As the social studies, art, and music classes in the middle school widen students horizons, some of your students may become fascinated with the art, costumes, and customs of other peoples in this and other times. The NCTM Principles and Standards calls for middle school students to be able to recognize and apply geometric ideas and relationships in areas outside the mathematics classroom, such as art, science, and everyday life.

Quick take on safety in the science classroom
With the increasing emphasis on hands-on instruction, it becomes more important than ever before for science teachers to be knowledgeable about laboratory safety issues. The National Science Education Standards say that students should have frequent opportunities to use a wide range of equipment, materials, supplies, and other resources for experimentation and direct investigation of phenomena. The National Science Teachers Association recommends that a minimum of 80 percent of science instructi

Grapher : number and operations (grades 6-8)
Using this online manipulative, students can graph one to three functions in the same window, trace the function paths to see coordinates, and zoom in on a region of the graph. Function parameters can be varied as can the domain and range of the display. Tabs allow the student to incorporate fractions, powers, and roots into their functions. Instructions for using the manipulative and a link to the National Council of Teachers of Mathematics (NCTM) standard for number and operations are included

History of flight to reality, advanced text
This website is an on-line textbook on the principles of aeronautics. The major focus is to examine the history of flight to current events and trends in aeronautics. Initially the reader will be introduced to principles of lift, thrust, and control. Further topics of discussion will cover the first jumpers, the first balloonists, the historical people and study of gliders, powered flight based on the Wright brother's experience, the age of flight, early space flight, the U.S. space program, the

Star life cycle
This instructional tutorial, part of an interactive laboratory series for grades 8-12, introduces students to the life cycle of stars. The tutorial's introduction compares human life stages with those of stars, and it describes the makeup of space. In the following sections, students investigate protostars, the equilibrium process of stars, what constitutes a star, and what happens in the late life of a star when the helium and carbon present in it start to be consumed.

Observe solar eclipses
This Earth science animation helps students compare three types of solar eclipses: total, partial, and annular. The introduction explains how the type of eclipse is determined by variations in distance and alignment between the Earth, sun, and moon. The animation follows the events of all three eclipses concurrently. Movie controls allow students to repeat, pause, or step through the animation, which can give students more time to compare the eclipse sequences. Copyright 2005 Eisenhower National

Cold Clouds and Water in Space
This article from Astrobiology Magazine reports on the discovery of water in cold regions of space. Using data from the European Space Agencys Infrared Space Observatory, astronomers have determined that water is abundant in these cold, or quiescent regions of space where there are no stars, and that the majority of it occurs as ice with a small amount of water vapor. It is thought that these cold regions of space might be the future birthplaces of low-mass stars like our own sun. Links to other

New York Times Daily Lesson Plan: Mathematics
These lesson ideas from the New York Times offer suggestions for ways to draw on real world issues and statistics to develop lessons in mathematics. For example, in one lesson students convert statistics about gun injuries into visual presentations, then use these as the basis for a poster campaign to teach children about the dangers of guns in home while another lesson idea involves designing brochures that are intended to explain specific mathematical concepts to a popular audience. Each lesso

What's That Stuff?
What's That Stuff? Well, the Web site provided by Chemical and Engineering News answers this question on many of those everyday items that are just a bit curious. For example, Silly Putty is a dilatant compound, which means it has an inverse thixotropy--that is, as a viscous suspension or gel, it becomes solid under the influence of pressure. The site explains the history and characteristics of this and over twenty other substances such as sunscreen, cheese whiz, baseballs, fluoride, new car sme

Ecological Footprint: Only One Planet
This two-minute sound segment discusses the concept of your ecological footprint. This is the amount of nature it takes to support your lifestyle. The speaker explains that if we divide up the total ecologically productive space on the planet by the number of people, what we get is five acres per person. In the United States, on average, we use about twenty-five to thirty acres per person to provide all of our services. This site is from an archive of a daily radio program called Pulse of the Pl
