Why Is a Drinking Bird Like a Dog on a Hot Day?


Ted Beyer, Educational Innovations, Inc.By:  Ted Beyer

Summertime—sun and fun!  For most of us (in the northern hemisphere at least) that means hot weather.  Heat does interesting things to the world around us, and to us as well.  On a hot day you tend to perspire.  Your body does this for a good reason:  as the moisture evaporates, it cools your skin, and thus helps to regulate your body temperature.

In contrast, dogs don’t perspire—they don’t have sweat glands!  So on a hot day you will see dogs panting—lots of rapid, shallow breaths with their tongues looking bigger than usual hanging out of their mouths.  That’s the doggie way of cooling off.  They are moving air over a wet surface—again using evaporation to lower their body temperature.

What’s the Weather? Check Your Weatherglass Barometer

by:   Ted Beyer

Predicting the weather is an age-old guessing game.

Over time, more and more sophisticated devices have been developed to aid in the guessing game.  Indeed, some of the largest computers in the world today are dedicated to modeling the weather using millions of data points collected all over the world—all in an effort to determine if going to the beach this weekend is a good idea, or if you should just stay home and binge watch Game of Thrones (again).

One of the earliest gadgets used to try and track barometric pressure was the Weather Glass, also known as the Goethe Barometer [1].   Evangelista Toricelli [2] came up with the first truly accurate barometer—the classic, mercury-filled device—sometime around 1643-44.  [Note: Educational Innovations has a mercury-free version of this Science classroom “must-have.”] Read the rest of this entry »
