Too Big or Too Small?
This lesson features three activities to promote number sense with large numbers, fractions, and decimal operations. In the first activity, students use proportional reasoning to determine whether \$1 million in \$1 bills would fit in a suitcase and how much it would weigh. In the second activity, students use circular regions to develop their sense of the relative sizes of fractions between 0 and 1. In the third activity, students play a game that develops their sense of the effect that operation

The Mexican American War
Conflict between U.S and Mexico started when Mexico insisted that its northern border lay along Nueces River, while U.S.claimed that it was farther south along Rio Grande. President Polk sent Zachary Taylor to the troubled area, but the two sides clashed and U.S. soldiers were killed, leading to Congress' declaration of war. The Mexican War gave U.S. more land, but led to more conflicts between free/slave states. This four minute video explains this and is accompanied by text to make it easier t

Philips: What if You Could Carry Your TV Around?
Philips Research demonstrated "the world's first matrix display that keeps functioning while being bent," and it has great expectations for the technology. Although it will probably not be commercially available for some time, it is intriguing to envision being able to unroll an e-book to read. A broad introduction to flexible displays is given on this Web site. Several potential technologies that could be used to manufacture the devices are discussed, including organic light-emitting diodes and

Semiactive Damping of Cables with Sag
Vibrations in support cables can be caused by wind, rain, or other forces acting on the attached structure. This can result in premature failure of the cable or its connections, thereby reducing the cable's useful lifetime. This research paper, from the University of Southern California civil engineering department, extends the previous work of the authors on smart vibration damping techniques. Through accurate modeling of the cable and including the properties of "sag, inclination, and axial fl
