P09: Galileo's Thermometer

 

Purpose: To demonstrate temperature and its effect on density.

Description:

 

This classic thermometer ingeniously uses the expansion of liquids and floating spheroids to measure temperature. The density of each spheroid has been adjusted to correspond exactly with the density of the supporting liquid at the designated temperature. The six spheroids float at low temperatures and sink at temperatures ranging from 65° to 90° F in increments of 5°. Warm the thermometer up before class and let the spheres drop as the water cools to room temperature.
