HERE’S HOW
1. Read the temperature from the
thermometer. To do this, find the top of
the colored bar and determine what
number on the scale it lines up with.
What is the “room temperature?”
2. Hold the bulb of the thermometer in
your fist tightly. Wait two minutes and
then read the temperature.
What is the temperature in your fist?
3. Fill a ceramic mug with the hottest
water you can get from your kitchen tap.
Gently place the thermometer in the cup
and watch the colored bar.

The colored liquid inside the thermometer
is alcohol with a dye in it. When alcohol
gets warmer, it expands. Because the
alcohol is sealed up inside a narrow tube,
when it expands it has nowhere to go but
up the tube. Because it always expands to
the same volume at a given temperature,
the thermometer manufacturer was able
to place a scale of numbers along the
tube, indicating the corresponding
temperature at each point.
