THERMOMETER GALILEO 7 BALL
Product Code : EL-PLE-15166
Eduscope India is a leading THERMOMETER GALILEO 7 BALL
Quick Answer: The Galileo Thermometer (7 Ball) is a striking demonstration instrument based on Galileo's discovery that a liquid's buoyancy decreases as its temperature rises, a popular piece of physics lab equipment India schools display as part of a wider laboratory equipment school India density and buoyancy demonstration collection.
Construction and Specifications
Built around a sealed glass cylinder holding a series of weighted glass balls, it turns a classic physical principle into a working classroom display, helping students visualise how a change in temperature affects density in a clear and memorable way. The instrument features a clear weighted glass construction housing a multicoloured set of 7 glass balls suspended in liquid. As the temperature of the water in the cylinder changes, its density changes too - the liquid expands or contracts, becoming less or more dense depending on conditions. At any given density, some of the glass bubbles float and others sink, and the lowest floating bubble indicates the current air temperature, marked in Celsius. This makes the thermometer an engaging, functional demonstration of density and buoyancy principles rather than a precision measuring instrument - ideal for illustrating thermal expansion concepts without requiring calibrated lab-grade accuracy. Standing 43 cm tall, it is recommended for adult use due to its glass construction, and makes an effective demonstration piece for lessons on temperature, density, and buoyancy, as well as an attractive display item for a laboratory or classroom shelf.
