Q1.
Let us now use a digital clinical thermometer to measure body temperature. You may measure your own temperature as well as the temperature of some of your friends… Record the temperature in Table 7.1.
Answer
The steps, in order:
- Wash your hands and the tip of the digital thermometer with soap and water.
- Reset the thermometer by pressing the reset button.
- Place the thermometer under the tongue and close your mouth.
- Wait till it gives a beep or flashes a light.
- Take it out and read the temperature on the digital display.
- Record it in Table 7.1, clean and dry the tip, and repeat for the next friend.
Sample answer (your own table will have your classmates’ names and their own readings):
| S. no. | Name | Temperature (°C) |
|---|---|---|
| 1. | Ananya | 36.8 °C |
| 2. | Ravi | 37.0 °C |
| 3. | Meenakshi | 36.9 °C |
| 4. | Imran | 37.2 °C |
| 5. | Kavya | 36.6 °C |
| 6. | Tenzing | 37.1 °C |
| 7. | Suresh | 36.7 °C |
| 8. | Phiban | 37.0 °C |
| 9. | Deepa | 36.9 °C |
| 10. | Arjun | 37.3 °C |
Notice that the ten readings are not all the same, but they all lie close to 37.0 °C — between about 36.6 °C and 37.3 °C here.
Precautions (the book’s own list): read the instruction manual first; wash the tip with soap and water before and after use; while washing, keep the digital part (the display) out of the water; and never hold the thermometer by its tip.
