Observing a Thermometer and Measuring Body Temperature

Aim of the activity

To record body temperature in degrees Celsius (ºC) and Fahrenheit (ºF)

Materials used in the activity

   1. Clinical thermometer  

    2. Cloth

Procedure

We take a clinical thermometer and observe the measuring scale on it. Then, we clean the thermometer and place it under our tongue for 1 to 2 minutes.

Now we remove the thermometer and note the temperature in both Celsius and Fahrenheit.

Note: You can take assistance from parents or a doctor.

Observation

S.N.	Measurement type	Value
1	Temperature in ºC	37.0 ºC
2	Temperature in ºF	98.6 ºF

 

Explanation

The clinical thermometer has two scales – Celsius and Fahrenheit.

Our normal body temperature is generally 37 ºC or 98.6 ºF. The clinical thermometer contains mercury inside.

Conclusion

Through this activity, we have learned how to use a clinical thermometer and two types of temperature measurement units – Celsius and Fahrenheit.

 

Frequently Asked Questions

   1.  What are the two temperature scales on a clinical thermometer?

Answer – The two common scales are Celsius and Fahrenheit.

   2.  What is normal body temperature?

Answer – Normal body temperature is around 37 ºC or 98.6 ºF.

   3. Which element is used in a clinical thermometer?

Answer - Mercury

 

   4. How can a doctor say you have a fever?

Answer – When the thermometer shows a value above normal body temperature, then the doctor says we have fever.
