Measure Temperature by Thermometer
At first, take a clinical thermometer. Now try to understand how temperature can be determined by it. Usually, this thermometer is scaled by line-marks ranging from 94 to 108 degree Fahrenheit. Even some of the thermometers are simultaneously scaled by line-marks from 35 to 42 degree Celsius. You will see a mercury column inside the thermometer. It rises up with the increasing temperature. Now place the thermometer under your armpit or tongue and leave it there for one minute. Observe the thermometer after one minute. Can you see any change taking place in the height of the mercury column? A fever (high temperature) is generally considered to be 38 C (100.4 F) or over.
From this you will be able to measure your body- temperature. Normal body temperature is about 98.6 degrees Fahrenheit (°F) or 37 degrees Celsius (°C). Your temperature often varies from 1 to 2 °F or ½ to 1 °C. Your temperature is usually lower in the morning and increases during the day. It reaches its high in the late afternoon or evening.
