The Galileo Thermometer is a thermometer based on an idea by the famous scientist Galileo Galilei (1564-1642). was a Italian physicist, mathematician, astronomer, and philosopher who played a major role in the scientific revolution. He has often been called the father of modern physics, and the father of modern science! His ideas served as the basis for many lessons taught in modern science classes today—in fact, his belief that the earth orbited around the Sun was so controversial he ended up being subject to house arrest in the later years of his life!! Searching for a way to measure exact temperatures, Galileo discovered a fascinating method of determining temperature. He placed several exactly weighted balls in a cylinder filled with a certain liquid. He found that the balls rose or fell according to the current temperature. By this method, he was able to determine the correct temperature. The scientific principle discovered by Galileo is that the density of a liquid changes as the temperature varies. Each of the glass balls is exactly weighted by partially filling the spheres with liquid. When the temperature rises, the liquid in the glass cylinder becomes less dense, and the heavier balls sink slowly to the bottom. Encased in a beautiful cherry wood base, this Galileo thermometer will totally get everyone’s attention!! Includes instructions on how to accurately read the temperature as well. This would make a great desk toy for anyone in your family interested in science!! Or get it for your favorite teacher!!
