# How to Read a Thermometer

## Presentation on theme: "How to Read a Thermometer"— Presentation transcript:

A thermometer is an instrument that is used to measure temperature.

The temperature of something tells us how hot or cold something is.

Temperature is measured in degrees.

is the symbol for degrees.
100 “100 Degrees”

Temperature is measured on two scales: Celsius and Fahrenheit.
37 C 98.6 F

“C” is the symbol for the Celsius scale.

Let’s count by 2’s… 2, 4, 6, 8, 10, 12…

The lines on most thermometers count by two’s.
102 100 98 96 94 92 90

What is the temperature on this thermometer?
C 100 96 94 92 90 88 C “98 degrees Celsius”

Try this one. C 90 88 84 82 oC 80 78 76 “86 degrees Celcius”

Normal body temperature is 98.6 oF.
This means it is between 98 and 99 degrees.

98.6 F This is a decimal point.

The temperature is “98 point 6” degrees Fahrenheit.
96 97 98 99 98.6 oF The temperature is “98 point 6” degrees Fahrenheit.

The temperature is “99 point 8” degrees Fahrenheit.
97 98 99 100 99.8 oF The temperature is “99 point 8” degrees Fahrenheit.

Now let’s try it with Celsius

What is the temperature?
99 100 101 102 What is the temperature? 101.2 oC

Try this one. 101 102 103 100 oC

If the temperature is below freezing, it will be a negative temperature.
-8 oC Remember… Below zero, you count backwards!

Try this one... -5 oC
