Ants

This is a paragraph from a section of a novel called Anthill, by entomology professor/naturalist Edward O. Wilson. This excerpt from the novel was published in The New Yorker, to which I subscribe, and when I flipped to it my first thought was to just keep flipping, because who wants to read a story about ants? But then I read the first paragraph, and then the second, and by then I was so engrossed that I couldn't put it down, and I read the whole story and wished for more. Anyway, this paragraph is about an ant traveling to a rival antbed to gauge their strength:

As the elite scout left on her journey, she remembered the route more or less precisely. She had been to the Trailhead territory before, and she carried a compass in her head, using the sun as a lodestar. This reliance on the sun could have been the source of a huge error for an ant, because the sun travels across the sky, its angle constantly changing. However, each ant also has a biological clock, set to the twenty-four-hour cycle and run with a precision far beyond the capacity of an unaided human brain. Using her clock, the scout was able to adjust her trajectory and stay on track.

Fascinating. I also learned that a queen ant can live for twenty years or more. Twenty years! An ant! Also, anthills contain "burial chambers" where ants dispose of all kinds of debris, including the corpses of their fellow ants, which are detected by smell alone; the "corpse carrier" ants are shunned by other ants. Also, as ants get older and weaker, they are sent out to the nest periphery to forage -- the most dangerous job for an ant -- because the loss of a weak ant is less detrimental to the anthill than the loss of a strong ant. This is the major difference between our species, says the author: "Humans send their young men to war; ants send their old ladies."

So now you know something about ants. Don't you want to learn more? Or is it just me?

Just this weekend some friends and I were discussing how fascinating ants were. In particular, the fire ant. Did you know a scientist, Dr. Walter Tschinkel, actually has molten metal casts of ant colonies? Here is a link to a picture of one: http://www.animalpicturesarchive.com/Arch05/1147141348.jpg

He pours hot metal down an ant colony and then digs it up to see how it is made. Very cool.

That does sound like an interesting read.

That does sound interesting. How much better would our human world be if we sent old ladies to war?

Coolness.

New Math

This word problem was on Mallory's math homework last week:

Lesia has 32 stickers. Diana has a few stickers. Lesia adds their stickers. She has to regroup when she adds. How many stickers does Lesia have? Circle the number.
3
5
6
8

We puzzled til our puzzlers were sore, but we still couldn't figure out the answer. I wrote a note beside the problem: "Mrs. G., this problem didn't make sense to either Mallory or her parents."

The next day the paper came back with a note from Mrs. G. She circled the last line of the problem and wrote:

"Misprint! This should have said Diana."

Okay! Whew! I was relieved to know that I wasn't, in fact, dumber than a second grader.

Except then I realized that I still didn't understand how the answer could be 3, 5, 6, or 8.*

I can't wait til she gets to algebra.



*Unless what they're calling "regrouping" is what we used to call "carrying the ones." In which case the answer would be 8. I think. Maybe.

Yard Sale. YARD SALE!

Anyone who doesn’t hear Tom-Hanks-as-Woody-the-Cowboy screaming that line…hasn’t spent much time around small children. Or at least around small children who like to watch Disney movies.

We had a yard sale this weekend – we being me, Chris, his sister Amy, and his mom. Yikes, it was exhausting. There was much hauling of boxes and furniture and standing around and chasing Mallory and Phoebe about the driveway all Saturday long. I made a hundred bucks – not too shabby, I guess. Chris made about $75 selling the “dregs” of his toy collection. The main point, however, was to sell our old living room furniture because we’re getting a new sofa and chair today (it’s being delivered as we speak!). We did sell our beat-up love seat for $25, but there were no takers for the beat-up sofa sleeper or the recliner. Alas, but that’s the way it goes.

Most of what I sold was baby stuff – clothes, bouncy seats, playmats, and so forth. It was a relief to see it go. Right after Phoebe was born I had the urg…

Confederation, confederation, confederation

Mallory has a big Social Studies test today. She’s not doing well in Social Studies, this year. When I asked her why her grades were so low, she said, “I don’t like Social Studies. Besides, no one can be good at everything.” I thought this was a fair point, but let her know that it was not acceptable for her to do quite so poorly, whether she liked it or not.

We studied for hours for this test. We read the chapter twice, summarized main points, went over vocabulary words, filled in blanks and did true/false quizzes. There were moments when I despaired – as when I asked, “The villages of the Cherokee people came together to form a...” and she said, “Um...bison?” But I think she knows the material pretty well; honestly I’m not even sure what else we could have done to get her prepared. I told her we would like for her to get at least a B.

I know she’s nervous. I’m nervous for her. I slept poorly all night.

But, I also know more than I really wanted to know about the early peoples of …
