Temperature and its Measurement | Class 6 Science Notes

7.3.3 Air temperature

Air temperature is an important parameter in weather monitoring and is commonly measured using thermometers hung on walls in school laboratories, clinics, and hospitals. These thermometers provide an approximate idea of the room or outdoor air temperature. Weather reports often mention the maximum and minimum air temperatures of the day, which vary due to changing weather conditions. Generally, temperatures rise as summer approaches and fall during winter. Air temperature is monitored at weather stations worldwide using various techniques. The data collected, including air temperature and other parameters, are used to make weather forecasts. The section also introduces Anna Mani, an Indian scientist known as the 'Weather Woman of India,' who invented many weather measurement instruments, reducing India's dependence on other countries. She also explored wind and solar energy possibilities, contributing to India's leadership in renewable energy.
