What is Temperature?
When we describe what a place is like, temperature is one of the first things we notice. Is it hot, cool, cold; comfortable or only just bearable? Most of us know what temperatures suit us best, but people become used to the range of temperatures in the country where they live.

Why is it Important?
We measure temperature in degrees Celsius, or degrees Fahrenheit. Generally, for humans, temperatures below 18 degrees C (64 degrees F) are a little cool for just sitting around. Those above 30 degrees C (86 degrees F) are a little too hot for strenuous exercise. Temperatures are measured in the shade generally, so that the heat of the Sun does not affect the measurement by actually heating up the instrument being used. In the Sun, temperatures can be as much as 10-15 degrees C (18-27 degrees) higher in calm weather, but much less in windy conditions. The same temperatures will not necessarily produce the same feeling of heat or cold indoors as distinct from outdoors, where wind, sun and humidity also play a part.
