Today in our Powerhouse science lesson we learned about something very important here in Texas...
air conditioning!
We are learning all about how to use the heat of evaporation for cooling and how to install an air conditioner and refrigerator in our Powerhouse. All air-conditioning systems need some sort of fan so we built one from our kit and tested it out.
After making observations about how the fan works it was time to install our AC and fridge in the Powerhouse. The kids installed the fan first. Next they installed a wooden skewer across the room with a wet paper towel hanging from it in front of the fan. On to the refrigerator, a simple glass baby food jar pushed through a hole in the side of the house into the AC room.
Here is a photo of the complete system with labels.
On Thursday we will be building a hygrometer to measure the level of humidity in our Powerhouse.
