## Project Slip-'N-Slide

Galileo is well known for having used experimentation to test what he saw around him and for using mathematics to describe his world. One of his most famous experiments resulted in one of his most famous mathematical formulas; in his inclined plane experiment, Galileo found that objects sliding down an incline accelerate, and in fact, he found the formula to describe the acceleration of an object on an inclined plane:

You and your teammates are charged with reproducing Galileo's inclined plane experiment.

You and your teammates will build an inclined plane out of objects you find. You may build the inclined plane any way you want and out of anything you want, but you must not purchase anything with which to build the plane, and you must not purchase the object which will move down the plane. In addition, the inclined plane must be at least 5 feet in length, and the angle between the inclined plane and horizontal cannot be greater than 50 degrees.

See the resources on this page for help, and feel free to do your own independent research.

In one week, you and your teammates will construct your inclined plane in class, and we will take video of your object moving down the inclined plane. We will analyze the video to find the winning team. The winning team will have the smallest result from the following formula:

*a = g*sin(theta).*You and your teammates are charged with reproducing Galileo's inclined plane experiment.
