All About Humidity!

Since the big connection between fog in various cities across the US seems to be humidity, we want to know more about what humidity is and how we can make the air more humid. 

We know that areas with high humidity are more likely to have fog, so maybe if we make our classroom more humid, we'll end up with fog!

We got a hold of three humidifiers and three humidity probes and did a whole bunch of investigating. 

​And we figured out that being closer to the humidifier meant a higher humidity reading, and the water level in the humidifier kept going down and down. 

We also read this really interesting article about a Chicago Bears' game in which the conditions literally changed from one half to the next.  What started out as a beautiful sunny day turned into a foggy nightmare where no one could see the game.  It turns out that the humidity increased drastically at the same time that the clouds rolled in and made it overcast.  This got us thinking that humidity might not be the only factor affecting fog, but that a temperature change (and possibly due to clouds?) may cause fog.  So we're starting to now think about not just putting a lot of humidity in our classroom, but maybe making it change temperature, too!

We're still not 100% sold on what humidity is and what it does once it's in the air (or not in the humidifier for that matter), so we'll be exploring humidity more!
