Measuring 
Temperature
Temperature measurement is all around us! From checking if you have a fever to 
conducting science experiments, thermometers help us understand the heat 
energy in objects and our bodies.
Clinical Thermometers
Digital thermometers used to 
measure body temperature. They 
run on batteries and show readings 
on a screen when placed in contact 
with your body.
Non-Contact 
Thermometers
Special infrared thermometers that 
became popular during COVID-19. 
They can measure temperature 
from a distance without touching 
the person!
Temperature Scales You Should Know
1
Celsius (°C)
Most common scale 
used in science. 
Normal body 
temperature is 
37 . 0° C.
2
Fahrenheit (°F)
Older scale where 
37.0°C equals 98 . 6°F. 
Less used in science 
today.
3
Kelvin (K)
The official SI unit for 
temperature used in 
advanced scientific 
research.
Fun Fact: All three temperature scales are named after the scientists who 
developed them!
Laboratory Thermometers: Your Science Lab 
Partner
Laboratory thermometers are glass tubes with a bulb containing liquid. As 
temperature changes, the liquid rises or falls, showing the temperature on the 
marked scale.
1
Check the Scale
Look at the smallest 
division marks. If 
there are 10 divisions 
between 0°C and 
10°C, each small 
division reads 1°C.
2
Position 
Correctly
Hold the thermometer 
vertically. The bulb 
shouldn't touch the 
container's bottom or 
sides.
3
Read While 
Immersed
Keep the thermometer 
in the liquid while 
reading. Your eye 
should be level with 
the liquid column.
"Did you know?" Your body temperature can vary throughout the day! It's 
influenced by your age, activity level, and even the time of day. The "normal" 
37.0°C is just an average!
35°C
Lowest Normal
Human body temperature 
rarely goes below this
37°C
Average Normal
Standard healthy body 
temperature
42°C
Highest Normal
Human body temperature 
rarely exceeds this
