Description

This beautiful sealed glass container holds 10 colorful, carefully weighted glass balls. As the ambient temperature changes, the paraffin within the thermometer changes density affecting which baubles float and which sink, showing the temperature.

Students will long remember the dual lessons of buoyancy and fluid density of this historical thermometer replica. In addition, it is an elegant example of the glassblower's mastery! As the Galileo thermometer warms, the transparent fluid becomes less dense. The related buoyancy forces decrease* and so the enclosed glass bulbs tend to sink. Notice that the higher density bulb ( labeled '60 degF') is the first to sink. As the thermometer cools, the transparent fluid becomes more dense. The related buoyancy forces increase and so the enclosed glass bulbs tend to float. Notice that the higher density bulb ( labeled '60 degF') is the last to float. *As the temperature rises, the thermometer fluid expands and becomes less dense. On the other hand, the density of each glass bulb is fixed at its own temperature rating as determined by the manufacturer. Notice that bulbs of a higher temperature rating and lower density are the first to float and the last to sink.

These are really neat. I have owned a couple. There should, however, be a flammability warning on this. Note that the info states it is filled with paraffin. My daughter's in-laws used to keep one on their wood stove (never used) as a decoration. Then one chilly holiday they decided to fire up the stove. The resulting fireball created a lot of damage, fortunately no injuries. So, keep away from sources of heat and sparks.

NGSS

This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.

Elementary Middle School High School

K-ESS2-1

Students can use the thermometer to make observations to use and share regarding local weather conditions to describe patterns over time.

3-ESS2-1

Students can use the thermometer to collect data to add to tables and graphical displays to describe typical weather conditions expected during a particular season.

4-PS3-2

Students can use the thermometer to collect data to provide evidence that energy can be transferred from place to place with heat.

MS-PS1-6

Students can use the thermometer in the design of a project to construct, test, and modify a device that either leases or absorbs thermal energy.

MS-ESS2-6

Students can use the thermometer in an investigation to develop and use a model to describe how unequal heating and rotation of the Earth cause patterns of atmospheric and oceanic circulation that determine regional climates.

MS-ESS3-5

Students can use the thermometer to collect data to provide evidence for how changes in weather may occur.

MS-LS2-3

Students can use the thermometer to collect data in the development of a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.

MS-ETS1-3

Students can use the thermometer in the design of tests and to gather data for a design solution about climate, materials, and natural resources.

HS-PS1-4

Students can use the thermometer to develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.

HS-PS1-5

Students can use the thermometer in an investigation that applies scientific principles and evidence to provide an explanation about the effects of changing the temperature of reacting particles on the rate at which a reaction occurs,

HS-LS2-3

Students can use the thermometer to collect data in an investigation to construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions.

HS-ESS2-5

Students can use the thermometer to plan and conduct an investigation of the properties of water and its effects on Earth materials and surface processes.

HS-ETS1-1

Students can use the thermometer to collect data for use in analysis of a major global challenge. Specify qualitative and quantitative criteria and constraints for solutions that account for societal needs and wants.

Suggested Science Idea(s)

ALL LEVELS

Students can conduct investigations using the thermometer, providing evidence of release or absorption of energy.

K-ESS2-1

Students can use the thermometer to gather data in the schoolyard. This could include how temperature changes over the course of a day as the sun moves or weather conditions change.

4-PS3-2

Students can use the thermometer to collect data to provide evidence that thermal energy can be transferred from place to place.

MS-ESS2-6 and
MS-ESS3-5

Have students collect temperature readings so that they analyze and have a frame of reference to understand more complex thermal scientific principles or global temperature issues.

HS-LS2-3 and
MS-LS2-3

Students can use the thermometer to see the rise in temperature in a composting experiment where microorganisms give off heat as the cycle matter or other environments where aerobic and anaerobic conditions exist.
