2 How to Read a Thermometer

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

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

5 Temperature is measured in degrees.

6 is the symbol for degrees Degrees

7 Temperature is measured on two scales: Celsius and Fahrenheit C F

8 C is the symbol for the Celsius scale. C

9 Lets count by 2s… 2, 4, 6, 8, 10, 12…

10 The lines on most thermometers count by twos C

11 C What is the temperature on this thermometer? 98 C 98 degrees Celsius

12 C 90 Try this one. 86 o C 86 degrees Celcius

13 Normal body temperature is 98.6 o F. This means it is between 98 and 99 degrees.

14 98.6 F This is a decimal point.

15 o F The temperature is 98 point 6 degrees Fahrenheit. 96

16 o F The temperature is 99 point 8 degrees Fahrenheit. 97

17 Now lets try it with Celsius

18 What is the temperature? o C 99

19 Try this one o C

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

21 Try this one o C
