Middle and High School … from a Montessori Point of View
The Opte Project has produced a number of excellent maps of the internet. There is a profound beauty in the immensity of the interconnections that’s reminiscent of the suffusion of stars that can be seen in Milky Way on a dark night on an isolated beach. Unfortunately, their website seems to have not been updated since 2005.
The Guardian website has some very interesting glimpses into the mind of the artist, with a series of videos where Paul Trevillion describes his thought process as he draws different players for his You are the Ref strip.
Every week, artist Paul Trevillon poses, in text and cartoon form, some truly idiosyncratic situations that might come up in a soccer match in his You are the Ref strip on the Guardian website. Readers get a week to propose their solutions and then referee Keith Hackett give his official answers.
It’s a fascinating series, the subtext of which is that, while there is a lot of minutiae to remember – the actual diameter of a soccer ball is important for one question – the game official is really out there to enforce the spirit of the laws, enabling fair and fluid play to the best of their ability. This is a useful lesson for adolescents who tend toward being extremely literal, and have to work on their abstract thinking skills, especially when they relate to questions of justice. For this reason, I find that when refereeing their games it’s useful to take the time during the game, and afterward in our post-match discussions, to talk about the more controversial calls.
Some people knit bacteria, our students create models of plant and animal cells as an assignment, and Luke Jerram blows viruses in glass.
Interestingly, he does not use colors, just clear, transparent glass, because while almost all pictures you see of viruses, from scanning electron microscopic images to text-book diagrams, have color, the color is added for scientific visualization. So, he believes, his glass replicas are more realistic. This is described in this interview.
About the works:
The pieces, each about 1,000,000 times the size of the actual pathogen, were designed with help from virologists from the University of Bristol using a combination of scientific photographs and models.

The video below shows how it’s done.
There is a lot more information on the art and the science at the Glass Microbiology website.
After the joy of playing around with microscopy and staining last fall, it’s no surprise that someone has taken the science of staining and specimen preservation and turned it into art.
Iori Tomita has done an amazing job at making visible the internal organs of the specimens.
Using a method that dissolves an animals natural proteins, Tomita is able to preserve these deceased animals with striking detail–highlighting the finest and most delicate skeleton structures.
To further enhance the visual appeal of these ornate skeletons, Tomita selectively injects different colored dies into hard bones and soft bones to create a 3-d effect. Without the addition of the dye, the animals remain translucent.

Tomita’s website has some excellent photographs, and there appear to be two books available from Amazon.com.jp. More pictures can be found online here and here. Lisa Stinson at Wired has more pictures and details on the method.
In seeking their identity, adolescents try out a wide variety of different personas. These are often closely associated with changing appearance and style. What I find interesting is how the different styles increasingly cross cultures and other traditional divides (like race). This is evident in Ari Versluis and Ellie Uyttenbroek’s photographic series Exactitudes.
There’s something sad about the loss of local cultural uniqueness to globalization; it’s a bit similar to the feeling you get when you hear about another interesting species becoming extinct. Curiously, however, when Versluis and Uyttenbroek tile together photographs of different people from the same subculture striking identical poses, they not only highlight the similarities between very different people, but also the minute variations that individuals employs to make the subgroup’s “uniform” their own.
All 128 pictures sets are thought provoking and worth a look. I think they would make useful subjects for students to reflect on (though, warning, there is a little nudity in one of the sets).

The Glue Society has a most interesting set of satellite images modified to look like major biblical scenes. CreativeReview has more pictures and details, including of the crucifixion and Noah’s Ark.
“We like to disorientate audiences a little with all our work. And with this piece we felt technology now allows events which may or may not have happened to be visualized and made to appear dramatically real,” say The Glue Society’s James Dive. “As a method of representation satellite photography is so trusted, it has been interesting to mess with that trust.”

I think this topic came up when we were talking about atmospheric circulation. The question was about if the winds generated descending, diverging air could have parted the Red Sea. The answer was no, because the general atmospheric circulation system is a thing of climate — averages of the weather — while any winds strong enough to part the red sea would be actual weather, like the storms we seem to have been seeing every day for the last few weeks.
Oddly enough, just last year researchers from the University Corporation for Atmospheric Research (UCAR) did a computer model that showed that hurricane force winds from the northwest could have uncovered an underwater reef to allow Moses his passage (the article is Drews and Han, 2010).
However, the scientists found:
[The] reef would have had to be entirely flat for the water to drain off in 12 hours. A more realistic reef with lower and deeper sections would have retained channels that would have been difficult to wade through. In addition, Drews and Han were skeptical that refugees could have crossed during nearly hurricane-force winds.

NPR’s article on the topic is worth a listen.
I’ve been helping my wife model the fluid flow through her apparatus, and she has some really neat results from some experiments where two chemicals react and block off the regular, symmetrical flow.
The streamlines look a bit like butterfly wings to me, so I modified the image a little. The original flow paths through the circular apparatus are below. I’m not sure which image I like better.
P.S. The other thing I learned from this little exercise is how to write Scalable Vector Graphics (svg) files (W3C has an excellent reference). With svg’s, like other vector graphics formats, no matter how big you blow them up you never loose resolution like you would do with a regular, rasterized image. Unfortunately, I still have to figure out how to include the svg files on this blog, so these png images will have to do for now.
