Did You Know?
Did you know that the Coriolis force is too weak to affect which direction water spins when going down a drain? You have probably heard that because of the rotation of the earth, water goes down the drain in sinks, bathtubs or toilet bowls counterclockwise in the northern hemisphere and clockwise in the southern hemisphere. Don’t believe it! One can find both counterclockwise and clockwise flowing drains in both hemispheres. The Coriolis force is simply too weak to affect such small bodies of water.

The French engineer Gaspard Gustav de Coriolis (1792-1843) first described this force caused by the earth’s rotation. It responsible for air being pulled to the right (counterclockwise) in the Northern Hemisphere and to the left (clockwise) in the Southern Hemisphere.

The Coriolis Effect is the observed curved path of moving objects relative to the surface of the Earth. Hurricanes are good examples. They curve to the right in the northern hemisphere and to the left in the southern hemisphere. What makes the hurricanes move in this way is the Coriolis force. The Coriolis force is too weak to operate on the moving air at the equator. In fact, the Coriolis force pulls hurricanes away from the equator.

ScienceKit.com has the Coriolis Effect & Foucault Pendulum Set and the Coriolis Effect Kit to help students learn more about this extraordinary effect of the earth's rotation.
Free Examples of High School Science Fair Projects
Here is where you will find a free list of High School Science Fair Projects.  The schools, organizations and individuals listed here have posted their finished science fair projects online giving you some great ideas and examples for your own project.

Many of these science projects use materials that are available around the house, making them very cheap, or completely free!  Others require materials that are available from reputable suppliers of science products like Edmund Scientific and ScienceKit.com.
Exploring Minds - Science Fairs Section
Exploring Minds is a program created by Merck Frosst, one of Canada’s leading research-based pharmaceutical companies. The Science Fairs section of Exploring Minds has a wealth of information that is useful for your science project.

There are two sections of particular interest. The first section is titled "A Few Projects." Here you will find nine complete science fair projects. The second section is titled "1001 Ideas, Thousands of Projects!" While not complete science fair projects, there is a lot of great material here that will give you ideas to develop your own.
E-Journal of Student Research: Science
The Science area located in the E-Journal of Student Research at the NSRC (National Student Research Center) has hundreds of abstracts of student research projects from Elementary through High School levels. Although these completed projects are basically in short form and without pictures, they are fairly detailed and should serve as good examples of free science fair projects.
