An increase in global water temperatures of only 2°F could raise the ocean level by two feet; melting ice caps could creating extreme flooding and changing the face of the landscape the world over…Low-lying cities, such as New York and New Orleans, would be the first to be affected. It has been estimated that if sea levels rose no more than 26 feet, senators of the future would travel from the Capitol by boat to visit the White House!

In this experiment we were able to calculate both the force and coefficient of static and kinetic friction using horizontal and inclined planes. Using force meters which were attached to computer equipment, the force of friction was easily measured and displayed in graphical form. In the following lab report our methods and conclusions are detailed.

Intriguingly, a similar mass extinction has ushered in the reign of the dinosaurs. Indeed, over the last 600 million years of life on earth, there seems to have been a cataclysmic change roughly every 60 to 70 million years, and smaller changes roughly every 30 million.
