Seeing Egypt in Ankh-Morpork

Anti-government protesters guard their barricade at the Kasr al-Nil bridge entrance into the square. They erected a complicated defense wall, strung a heavy electrical cable around 10 meters in front of the wall, and scattered lines of debris another 10 meters ahead of that to break up any attacks.

Following the ongoing convulsions in the Egyptian streets, I’m becoming more and more impressed by the research and thought that Terry Pratchett must have put into his novel Night Watch.

In typical Pratchett fashion, Night Watch has an amalgamation of influences, from fictional sources like Les Miserables, to historical events, like the Peterloo Massacre of 1819; however, the book follows a character immersed in the events that are remarkably parallel to what’s going on Egypt right now, especially with the Army trying to sit out events and things becoming somewhat medieval.

This is the first time I’ve been able to follow a revolution so closely, and it’s largely thanks to the volumes of raw reports streaming across the twitterverse, blogosphere and media websites. Pratchett gives us the wonderful characters that highlight the inherent conflict in the revolution: the police with their conflicting allegiances; the secret police that have to be dealt with; the idealists whose high hopes are bound to be dashed on the rocky shoals of human nature; and even down to the men selling food to the protesters behind the barricades.

Night Watch

I think I’m going to have to add this book to our reading list for next year.

At the end of Night Watch, the protesters win, and barricades come down when the old dictator is deposed. However, he’s replaced by a new dictator, who turns out to be just as bad as his predecessor. To paraphrase Pratchett, they’re called revolutions because they go round and round.

Words you shouldn’t say

Age-appropriate is quite the interesting phrase, particularly when it comes to adolescents. They are making the big transition to adulthood, but their maturity can vary widely even within the same age group.

Michael Chabon has a fascinating post on his, partially successful, attempts to read Huckleberry Finn to his pre-adolescents without the racial slurs. There is even going to be a edition of the book put out that replaces all the n-words with “slave”. I can see their point, but I’m not sure I’d go for it, even in the middle school.

The internet poses its own set of conundrums. One of my students mentioned a certain website on their blog that they, “do NOT recommend it for kids under 12 due to foul language”. The recommended site is quite fascinating and entertaining (I got sucked into it for quite a while), if a bit harsh to the denizens of the website, etsy, but the writing can be quite adult. I’m not quite sure how to address this. I really appreciate how forthright the student was with the (convenient?) age recommendation, but I’d probably make the cutoff a bit older myself.

Differentiating what’s age-appropriate and what’s not is so terribly subjective. I guess the key difference between the website and Huck Finn is in its purpose and relevance within the text. Twain’s harsh language to makes a specific point about race relations that’s relevant to middle-schoolers. The website takes uses a more adult language to relate to an older audience.

Jurassic Park: Web of Issues

Web of issues for the movie Jurassic Park.

Well we watched Jurassic Park last night and concluded it with a discussion about the issues underlying the movie, the same way we’ve been studying analyzing the issues underlying texts. Discrimination based on race and obesity came up first (the fat guy and the black people “always” die), but I was able to coax a bit of discussion about the role and responsibility of science and scientists. Our discussion is summarized in the graphic organizer above, but there are many more subtexts to the story that we did not have time to explore.

Jurassic Park by Michael Crichton (the book).

I like both the movie and the book because, like most good science fiction, they explore some interesting issues that relate quite nicely to the curriculum. Jurassic Park has a nice little introduction to DNA and gene sequencing that is tied to some the history of life on Earth. As works of art in their respective fields, however, I prefer the movie. The novel has a lot of wonderful detail, and the scientist in me loves the detail, but the characters are not as well drawn and the story seldom strays from its main thesis, scientific hubris. What it has to say about that issue is well expressed and well researched so it does capture the interest of the reader. (The follow-up book, “The Lost World”, sails adrift of the science, is logically incoherent and has a proportionate deterioration in the quality of the writing.) I do however recommend the original Jurassic Park book to my students as a personal novel.

Steven Spielberg makes a great movie, extracting empathetic performances from the actors. Since the book’s author, Michael Crichton, also wrote the screenplay, the movie stays true to the core issues in the text. I think its a great example of a successful, dare I say synergistic, collaboration.

Tomorrow, instead of retelling around the issues in writing, my students are going to try to do so in a skit. This could get interesting.

Calvin and Hobbes search engine

The Complete Calvin and Hobbes is a wonderful resource.

Calvin and Hobbes is one of the most deeply interesting and intellectually hilarious comics. It ran from 1985 to 1995 when Bill Watterson decided it was time to stop, so it retained a persistent quality throughout its run. Watterson was very serious about the newspaper comic form and did a lot of experimenting with C&H. His thoughts are nicely documented in the paper collections.

Though I have the books, it’s nice to have archives of the entire series online. Even better, Michael Yingling recently created a Calvin & Hobbes Search Engine that can find key words in the dialogue, so now you can quickly find that more obscure script to brighten up your day.

I really hope that Yingling has finessed the copyright issues because this is a great resource for teachers looking for that little something to spark the imagination. The strips often go into issues at such depth that some of the series make great examples for literature discussions. I find the issues resulting from the transmogrifier/duplicator to have a powerful, though more light hearted, equivalency to the novel Frankenstien. I also am partial to the philosophical world-view of Calvin’s father.

Teach.Genetics: Family trees

Handy Family Tree exercise from Teach.Genetics.

Dealing with genetic traits and family trees can be kind of tricky sometimes, particularly with early adolescents who are still learning about personal boundaries and have the potential for sharing too much information. One alternative to delving too deeply into personal family histories is to stress the less invasive traits. Anna Clark has had some success (and the students liked it) using the Handy Family Tree, from the University of Utah’s Teach.Genetics website.

John Wyndham's The Crysalids. (via Powell's Books).

I also discuss some of the thornier issues when we do the John Wyndham book, The Chrysalids. It can be an uncomfortable book, but has the emotional separation of fiction.

Teach.Genetics is a great resource. They have a number of “Teach and Go” exercises like this one, and some interesting interactive applications. I’ll post more as I browse more through their website.

Making pectin

Extracting pectin for making jelly does not seem to be that hard. Sam Thayer has a nice little article on how to get pectin from apples. The blog Spain in Iowa, has some nice pictures and video of how they extracted pectin from apples and what the result should look like when you test it by putting a teaspoon of pectin into a teaspoon of rubbing alcohol. Almost immediately (but leave it in for a minute), the pectin should jell in the rubbing alcohol and you should be able to pull it out using a fork.

Basically, all you do is chop up the apples, cook them for a long time over low heat till they’re broken down, and then strain out the liquid produced. Since I have access to a lot of green apples that won’t be used for anything else, I tried the process myself. Using a pot full of apples I produced a lot of liquid; way more than I could ever use, but the process seems to work fairly well.

One 8 quart pot of apples produced 8.75 cups of liquid. I’d planned to use the home-made pectin in my currant jam, but testing the currant juice showed that it had just as much, if not more pectin than my boiled apple residue. I guess I’ll save the apple pectin for future use.

Ideally, Student Run Businesses should sell goods or services that are worth the value paid. While I appreciate that there is some value to the sympathy of friends and family, it is nice when customers believe they’re getting a good deal even without that. One direction I try to direct the students is toward making things from scratch, because it adds so much to the experience. Then they can have the extra value of using natural, perhaps even organic, ingredients and satisfying Michael Pollan’s rules for good eating.

In Defence of Food by Michael Pollan

My students have not yet tried jam or jelly-making, but if they do natural pectin would be great.

Origin of life lab

ENSI has a set of great labs that can be used all the way from the middle school to the university level. They deal with the nature of science, the origin of life, evolution and genetics/DNA. (Thanks again Anna Clarke for the link.)

Amoeba (image from Wikipedia). This image is part of a neat video of amoeba movement.

I’m thinking that the Creating Coacervates lab, the only one on the origin of life section, might fit into my orientation cycle plans. Coacervates are small, microscopic blobs of fat (lipids) that look like, and have many of the same properties as cells, amoebas in particular. They can be produced with simple chemicals. One of the key things I’d like to start the year with, is the idea that:

complex life-like cell-like structures can be produced naturally from simple materials with simple changes. Flammer, 1999.

These abiotic blobs can be compared to the protozoans in a water droplet sample while we learn how to use the microscopes. It also ties into the Miller–Urey experiments that produced amino acids using electricity and simple compounds: water, methane, ammonia and hydrogen gas. The Miller-Urey experiments will pop up later when we read Frankenstein.
