Class 6 Science Chapter 7, Temperature and its Measurement, begins in Shillong as Phiban checks her brother Lambok’s fever with a thermometer. Inspired by Indian meteorologist Anna Mani (‘Wrong measurements are worse than no measurements at all’), it covers clinical, laboratory and air thermometers and temperature scales.
What Class 6 Science Chapter 7 Covers
7.1–7.3 Hot or Cold & Measuring Temperature shows why touch cannot reliably judge temperature (Activity 7.1) and compares clinical thermometers (digital and mercury-free, measuring body temperature in °C and °F around 37.0 °C / 98.6 °F) with laboratory thermometers (typically –10 °C to 110 °C).
Correct Reading, Least Count & Air Temperature demonstrates finding the smallest division (least count) of a laboratory thermometer, keeping the bulb immersed vertically without touching the beaker walls, reading at eye level, comparing Celsius, Fahrenheit and Kelvin (SI unit of temperature) scales, and tracking maximum/minimum air temperatures.

FAQ
Why can a clinical thermometer not be used to measure boiling water?
A clinical thermometer has a small temperature range (around 35 °C to 42 °C) suited only for human body temperature and would get damaged or burst at 100 °C.
What are the Celsius, Fahrenheit, and SI units of temperature?
Normal human body temperature is 37.0 °C on the Celsius scale and 98.6 °F on the Fahrenheit scale; the SI unit of temperature is kelvin (K).
