So the other day, we had a phenomenal guest speaker, Mr. Swoape. He is from the gas company---the natural gas company. I learned so much from him. He taught us that in order to start a fire, (DON"T TRY THIS AT HOME OR ANYWHERE!!!!) you need 4 things: oxygen, fuel, a catalyst, and what's the fourth?---MATH!!! I thought you only needed the first 3 things. It turns out the proportions of oxygen and fuel have to be right to start a fire.
Mr. Swoape also taught me that when I'm metal detecting, if I'm going to dig deeper than just a couple of inches, or if I'm going to plant a tree, I need to call 811 first. It's a FREE service, where the gas company will come out and make sure there are no gas lines running where I want to dig, so I don't bust a pipe and put myself and those around me in danger. Natural gas is actually harmless until there is so much of it, that it starts taking the place of the oxygen or it lights on fire! So if you smell something that smells like rotten eggs, a skunk, or a dirty diaper, it might be a leaky gas line, so GET OUT OF THE BUILDING AND TAKE ELVIS WITH YOU!!! I also learned the different colors of each utility. When you see these lines on the ground, here's what each color means:
White- Dept. of Transportation
Red- Electric
Blue- Water
Yellow- Gas
This presentation was awesome! I would love to have him present in my classroom one day. It was so exciting! I wish I had taken a picture of it..I picked the wrong day to forget my phone. For a picture and a little more info, check out Kim Geary's blog:
