Class 6 Science - MP
Temperature and its Measurement
In the chapter 'Temperature and its Measurement', Class 6 students explore the concept of hotness and coldness, moving beyond just touch to accurate scientific measurement. Students learn about the construction and working of clinical and laboratory thermometers, the units of temperature including Celsius and Fahrenheit, and precautions needed while handling them. This chapter is fundamental for the MP Board science curriculum as it builds basic observational and measurement skills. It frequently features in exams through conceptual questions, diagram labeling, and numerical conversions, carrying around 4 to 6 marks in the final examinations.

Temperature
A reliable measure of the hotness or coldness of an object, measured using a device called a thermometer.
Clinical Thermometer
A specialized thermometer used to measure human body temperature, typically ranging from 35°C to 42°C.
Laboratory Thermometer
A thermometer used to measure the temperature of water and other substances in a science lab, usually having a wider range from -10°C to 110°C.
Celsius Scale
The standard metric scale for measuring temperature, where water freezes at 0°C and boils at 100°C.
Transfer of Heat
The natural flow of heat energy from a body at a higher temperature to a body at a lower temperature.

Board Exam Info
In the MP Board Class 6 Science exam, this chapter typically carries about 4 to 6 marks. Common question types include short answer questions about precautions while using a clinical thermometer, differences between clinical and laboratory thermometers, and filling in the blanks regarding normal body temperature.
Frequently Asked Questions
Why can't we use a laboratory thermometer to measure human body temperature?
A laboratory thermometer does not have a kink (constriction) like a clinical thermometer. As soon as you take it out of the mouth, the mercury level starts falling quickly, giving an incorrect reading.
What is the normal temperature of a human body?
The normal temperature of a healthy human body is 37°C (Celsius) or 98.6°F (Fahrenheit).
Why is mercury used in thermometers?
Mercury is used because it remains in liquid state over a wide range of temperatures, does not stick to the glass, and is shiny and easily visible.
