Golden rectangle (grades 6-8)
This virtual manipulative can help students visualize the golden rectangle. It shows how a set of golden rectangles is generated by using the golden ratio (the ratio of the longer side to the shorter side of a golden rectangle) to create smaller golden rectangles within an initial rectangle. The size of the initial rectangle can be varied, and the center of the spiral generated by the applet can be seen. Instructions for using this online manipulative are included on the site, as is a link to th

Observe images of advection fog
This Earth science resource presents six photographs depicting examples of advection fog along various coastal areas in the United States. The introduction explains how advection fogs form and provides a brief explanation of how they differ from radiation fogs. Students are instructed to click on each labeled image to see an enlarged version of it. Each enlarged version includes a caption that describes the location of the fog relative to local landmarks in the picture. Copyright 2005 Eisenhower

How can you go eighty miles per hour on a bicycle?
Is it possible for a human to ride a bicycle at the speed of 80 miles per hour? This riddle asks students how such a feat could be accomplished. On a clue page, students read about and view a brief video clip of two boys experimenting to see if a certain combination of gears can help them bike faster. When students select the correct answer from the riddle's three answer choices, a video clip plays about a unique kind of aerodynamic bicycle. A cyclist talks about the special design features--the

Measuring What Counts: A Conceptual Guide for Mathematics Assessment
To achieve national goals for education, we must measure the things that really count. Measuring What Counts establishes crucial research-based connections between standards and assessment. Arguing for a better balance between educational and measurement concerns in the development and use of mathematics assessment, this book sets forth three principles--related to content, learning, and equity--that can form the basis for new assessments that support emerging national standards in mathematics e

Energy-mass conversion
How do physicists make new particles? In this page of a particle physics tutorial, students are introduced to the concept of converting kinetic energy to mass. Students read that low-mass particles placed into an accelerator can be smashed together to produce more massive particles through the conversion of energy to mass. They see an example in which two pieces of fruit are accelerated and smashed, and additional types of fruit are produced. Copyright 2005 Eisenhower National Clearinghouse
