How did an eighth-grader’s science fair project inspire a new way to
tackle rising levels of carbon dioxide in the atmosphere? Claire
Lackner’s father Klaus, a geophysicist at Columbia University, had a
brainstorm after he saw how Claire used an aquarium pump to capture carbon dioxide in the air. A decade later, Dr. Lackner is testing a product inspired by his daughter’s vision. This 12:46 long video tells of this story with the emphasis on what CO2 is what
Debits and Credits - Accounting
The difficulty with accounting has less to do with the math, as it does with its concepts. Now, there is no more difficult yet vital concept to understand than that of Debits and Credits. Debits and Credits are at the very heart of the 'double entry bookkeeping' that has been the foundation stone on which the financial world's accounting system has been built for well over 500 years. Now, given the length of time, is it any wonder that confusion has surrounded the concept of Debits and Credits

GPS Receiver Basics
Students familiarize themselves through trial and error with the basics of GPS receiver operation. They view a receiver's satellite visibility screen as they walk in various directions and monitor their progress on the receiver's map. Students may enter waypoints and use the GPS information to guide them back to specific locations.
Big Dipper Mobile
By building their own Big Dipper mobile, kids learn that the distance between stars is not what it appears to be in this OLogy activity. The activity directions are provided as both a Web page and a printable PDF. The activity begins with a brief overview about how the small size of stars and the close distance between them are illusions. Kids then create a replica of the Big Dipper which realistically shows the relative size and distance of the constellation's stars -- allowing kids to view the

An Analysis of Bone/Muscle Movement
By manipulating a simple kinematic model representing the leg and foot, students can get hands on information about the interaction of bones and muscles in humans. Having worked with the model, they then are able to predict and analyze the properties of bone/muscle systems in other vertebrates and understand how these systems have become modified during the course of evolution for a particular life style. By the end of the exercise, students have learned both traditional information (cellular st
Motor Exam: Anatomy: Localizing a UMN Lesion
An UMN lesion is on the opposite side of the clinical findings for a lesion above the decussation of the pyramids (where the corticospinal tracts cross) whereas it is on the same side as clinical findings if the lesion is in the spinal cord. The first principle of neurologic diagnosis is regional or anatomical localization. In order to become skillful the student must understand how structure relates to function of the nervous system. The neurologic examination permits "dissection" of the nervou
African Fires during 2002 (WMS)
This animation shows fire activity in Africa from January 1, 2002 to December 31, 2002.
