1. How to Read a Thermometer

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

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

4. Temperature is measured in degrees.

5. is the symbol for degrees.
100
“100 Degrees”

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

7. “C” is the symbol for the Celsius scale.

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

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

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

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

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

13. 98.6 F
This is a decimal point.

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

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

16. Now let’s try it with Celsius

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

18. Try this one.
101
102
103
100 oC

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

20. Try this one...
-5 oC
