Sky Station
While satellites are the current backbone of telecommunications and wireless infrastructure, the company that maintains this Web site envisions a completely new technology. The Stratospheric Telecommunications Service (STS) relies on "lighter-than-air platforms which are held in a geo-stationary position in the stratosphere (approximately 21Km) over a major metropolitan area." The Sky Station company documents much of the STS theory online, as well as maintaining news and information articles ab

Observe one place at many scales
Developed for high school students, this Earth science resource utilizes a set of six enlargeable images to illustrate the meaning of map scale. Introductory text explains that because of the incremental changes in scale, the details in each image appear ten times larger than in the prior image. The first image in the set was taken at a scale that shows the globe, and the final image shows a city block in Atlanta, Georgia. There is an animation below the images that begins with the global view a

Floor tiles
This Java applet enables students to develop tessellations, which are patterns on a plane that do not overlap. The student is given a square that can be distorted into quadrilateral shapes by dragging its corners. Users can select colors for the alternating quadrilateral pattern, and a button displays information about the quadrilateral in a second window. The window lists the coordinates of the vertices, angle measurements, side lengths, area, and perimeter of the quadrilateral. From the applet

Observe an animation showing evidence of the carbon cycle
In this visual resource about the carbon cycle, students are presented with an animation and accompanying text that focus on carbon and plants. The text addresses how plants fit into the larger carbon cycle, including how carbon enters and leaves the biosphere, and it explains what students are viewing in the animation. The animation shows false color images on a flat map of the world. When the viewer clicks on the image (or the play button), the animation plays, and color patterns reveal change

Helping Children Learn Mathematics
Results from national and international assessments indicate that school children in the United States are not learning mathematics well enough. Many students cannot correctly apply computational algorithms to solve problems. Their understanding and use of decimals and fractions are especially weak. Indeed, helping all children succeed in mathematics is an imperative national goal. However, for our youth to succeed, we need to change how were teaching this discipline. Helping Children Learn Math

The future of energy, issues
There are many issues surrounding the use of energy today. This section of a series about the future of energy introduces students to four different issues: consumption, efficiency, infrastructure, and environment. Descriptions of the issues investigate such topics as environmental considerations, clean air, dependence on foreign fuels, environmental impacts, an aging energy grid, and appliance efficiency, among others. In the descriptions, students can access glossary definitions of highlighted

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

Meeting in the middle
With this hands-on activity, students apply measurement and communication skills to describe the location of the end of a tunnel they plan to construct. The goal is for a student to form a precise location description so that a second student planning to construct from the other side can determine the location of the tunnel end. Students work in pairs one person standing on each side of an upright piece of corrugated cardboard or foam core board. Both students mark a tunnel entrance on their sid

1.7 Homologies
This unit is concerned with macroevolution – the patterns and processes of evolution above the species level. A crucial consideration in macroevolutionary studies is that of the evolutionary relationships (phylogeny) of the organisms in question. The unit begins with an introduction to the scope of macroevolutionary studies and illustrates methods of reconstructing phylogeny, from both morphological and molecular data.

Who Can Make the Best Coordinate System?
Students will learn about coordinate systems in general by considering questions concerning what it is that the systems should do, and who decided they would look the way that they look. They will attempt to try and make their own coordinate system using a common area across all groups and compete to see who can make the best one. Students then analyze why it is that some systems work better than others and consider what those observations mean for evaluating and choosing geographic coordinate s

Not So Simple
Students expand upon their understanding of simple machines with an introduction to compound machines. A compound machine — a combination of two or more simple machines — can affect work more than its individual components. Engineers who design compound machines aim to benefit society by lessening the amount of work that people exert for even common household tasks. This lesson encourages students to critically think about machine inventions and their role in our lives.
