Did you know that humidity is the amount of water vapor in the air?  Humidity can help predict if there will be rain or snow, dew, or fog.  Low humidity makes it feel cooler, while high humidity makes it feel warmer than the actual air temperature.   The instrument used to measure humidity is called a hygrometer.  Some hygrometers are made with human or animal hair.  The length of a piece of hair changes with humidity, which can be used to move a dial to show the current humidity level.

We hope that you have a fantastic day at school.  Remember to think kind thoughts, use kind words, and do kind things.  We Love You.

Bonus Fact:  There are different ‘kinds’ of humidity: absolute humidity, relative humidity, and specific humidity.  Weather reports often use  ‘relative humidity’.
