A. Use a Thermometer to measure Temperature
Temperature is measured with a thermometer usually made of a glass tube
with colored alcohol. As the air gets hotter, the level of the liquid rises and,
as the air gets cooler, the level falls. The temperature of the air is always
changing. Air temperature is a very important part of weather measurement. It is
recommended to begin by giving each group a thermometer and let each student
practice reading the indoor temperature. Students should look straight at the
thermometer at eye level.
Make a Thermometer
Introduction: You will learn how a thermometer works by making it however
you will need a commercial thermometer to record the outside temperature.
- Rubbing Alcohol
- Cylinder shaped clear jar or bottle (bottles with a narrow neck work
- 1 straw
- Modeling clay
- Food coloring
Use a Thermometer to measure Temperature
(unfortunately the thermometer you just made will NOT be able to provide
- Go outside and wait two minutes before you take a reading. This is to allow
the thermometer to adjust to the outside air temperature.
- When recording the temperature, please keep the following in mind
- Take outdoor reading away from the building.
- Take the reading out of direct sunlight (in the shade if possible).
- Hold the thermometer close to eye level; it should never be on the ground.
- Do not allow rain or snow to fall on the thermometer.
