“Magicicada Brood II will make its 17-year appearance when the ground 8” down is a steady 64°F,” reports Radiolab in this excellent Cicada Tracker DIY project page. And why 17 years underground? From Scientific American:
The curious phenomenon of the cicada’s periodical life cycle is the subject of much debate among scientists, who are limited to no small extent by the infrequency of the insect’s visits to the surface. Most agree, however, that climate shifts — notably the rapid warming following the end of the last ice age — have played a role.
There are seven species of periodical cicadas in North America, four bound to a 13-year cycle, three in a 17-year cycle. All are characterized by black and orange bodies, and males woo their mates with species-specific choruses that can be deafening in large numbers.
The genetic similarity of these seven species suggests a common ancestor in the last 8,000 years. And because emergence seems closely linked to soil temperature and moisture, it is likely that climate has played a role in both regulating their life cycles and cueing their appearance.
Cicadas don’t sting or bite. After a few weeks making noise up in the trees (measured at 94 decibles), eggs will be laid and will hatch. After feeding on sap, these hatchlings will drop down to burrow and live underground, next seen in the year 2030.
1. It’s Friday!!!
2. I discovered the Chinese keyboard on the iphone.
3. I really like joking around with my 6th period class. It’s a small class, so I get a lot done. They like to get off task, but only because you can tell that they are all comfortable with each other. And, one look will get them right back on track. They are still innocent, and will laugh at silly little things, and I appreciate that at this age. If I’m having a bad day, or I know I have a not so exciting lesson, I know that this group of kids will be forgiving, and make me smile at some point in the 80 minute period.
Met up with a college friend that I hadn’t spoken to in 2 years, and she gave me a tidbit of advice - to write down 3 simple things everyday that make you happy. So, here is today!
1. Met up with Erica.
2. Got my new iPhone case/screen protector in the mail.
3. Confirmed for Honeywell Space Camp for Educators in June!
Did you know, you can quit your job, you can leave university? You aren’t legally required to have a degree, it’s a social pressure and expectation, not the law, and no one is holding a gun to your head. You can sell your house, you can give up your apartment, you can even sell your vehicle, and…
