Mural

Artist Mary Cour throwing herself into the mural.

We’ve been really lucky to have the artist Mary Cour help us out with our classroom mural. She came up with the idea about two cohorts of students ago to paint students’ outlines on the wall and let the students fill them in with words and images that were meaningful to them. Early adolescence is a time of self-discovery and exploration, so this type of project is a wonderful way to encourage self reflection. I let students work on their silhouettes during personal reflection time, and they’re always eager; it’s easy to see why Facebook is so popular with this group.

The mural became quite the marker for the students and for the school, so now, every two years, we add the new group of students to the wall. The new outlines are superimposed over the older ones so you can still see previous generations of students, a tangible reminder of their legacy in the classroom.

Shades of grey

We’re focusing on the biological sciences in the natural world this year. I’m a great admirer of the sketches and illustrations in the notebooks of the great naturalists so that’s how I plan to integrate art. Our art teacher is a great help, and she started us up with sketching in pencil and our first exercise was to get a feel for the different soft pencils. The little panel we shaded in with B, 2B, 4B and 6B pencils is a nice metaphor for what we’re working on in middle school.

There was a bit of giggling though. Last year one of the poems presented was:

Said Hamlet to Ophelia,
I’ll draw a sketch of thee,
What kind of pencil shall I use?
2B or not 2B?
Spike Milligan

This was just before we saw Hamlet in St. Louis. Though I don’t know if the poem make the famous line more comprehensible.

Sarajevo roses

Mortar shells landing on concrete create a pattern almost like a floral arrangement. In Sarajevo, after the Bosnian War, the mortar scars in the sidewalks were filled in with red resin. The results are called Sarajevo Roses.

Flickr has a nice map that links to Rose pictures in downtown Sarajevo.

I found out about these from reading a recent set of View From Your Window Contest entries on Andrew Sullivan’s blog.

Glassworks

Molten glass, upwards of 2000 degrees, cools slowly, quickly, slow enough to pull, twist, fast enough to feel the brittleness between metal tweezers in seconds. Runny to viscous as it cools. Change of state — freezing — feel it in the glass.

Tweezers and jacks keep hot glass at a distance. Third class levers require balance and firmness to control their mechanical advantage.

Glass, silica, SiO2. Quartz crystals, ordered array of molecules. Glass, no organization, amorphous.

Furnaces blast hot, you can see the yellow-orange color, you can feel the hard infra-red light, thermal energy. IR – long wave – less energetic. When extra heat is needed, the blue/ultra-violet flame of propane (mixed with oxygen). UV – short wave – high energy – hard on the eyes though you can’t see it.

Combustion needs three things, heat, fuel and oxygen. Propane, C3H8, not methane, CH4 – the greater energy density. Propane, C3H8, not butane, C4H10 – is a gas not a liquid. To burn real hot needs extra oxygen.

Propane torch.

Conservation is a challenge. Furnaces –> heat –> lots of energy –> bad. Natural light, big doors, lots of windows. Recycle glass (at least the clear glass). No need for heat in the winter. Drink lots of water in the summer.

3rd Degree Glass Factory, make your own paperweights. About 12 minutes per person. Excellent way to spend a morning. Really cool faucets and water basins in the bathroom.

Vietnam in pictures

A slew of ideas and conflicts swirl around the Vietnam War: democracy, communism, dictatorship, freedom, colonialism, domino theory, chemical warfare, technology …. We’re supposed to look at wars through the lens of the “Characteristics of War”, but what do offense and defense mean in a war like Vietnam? A close examination of any of these words in the face of Vietnam leaves more questions than answers. The Boston Globe has a heartbreaking collection of images from the Vietnam War that give a remarkably multifaceted view of the conflict and its consequences. The photos are iconic and some are graphic.

The photographs in the Boston Globe were mostly taken by western photographers (some were from the U.S. military), whose journalistic culture inspired them to try to capture all aspects of the war, to tell the whole story, independent of their own allegiance. There were fewer North Vietnamese photographers and their job was to capture images that would promote their side of the war. Even so, some of their photographs are also amazing and offer another perspective.

National Geographic collected some of these photos in Another Vietnam: Pictures of the War from the Other Side. More photos are available from SnugMug.com, and National Geographic has a documentary on North Vietnamese photographers called, Vietnam – The Unseen War (a 5 minute preview is available on VEOH).

These images help tell the story of how powerful the media can be, particularly in a democracy. What’s also interesting is the youth of many of the combatants on both sides.

Best nature photos

The Guardian newspaper put together an excellent collection nature photographs for auction for an Earth Day charity. I particularly like the pictures from the Franklin River, south-west Tasmania, Australia and Stone Canyon, Arizona/Utah, U.S.A.. Apart from the wonderful composition and spectacular lighting, I like the effort and meaning behind these images.

Slickrock Formation, Paria Canyon (from Thundafunda). As beautiful as it is, this is not the Stone Canyon photo in the list.

According to the Guardian, the Franklin River image was instrumental in preventing the flooding of the river for an hydroelectric dam. The Stone Canyon picture was used to try to have the area declared a national monument. I particularly appreciate the effort of Jack Dykinga, who took the Stone Canyon photo. He hiked up the slot canyon at 3:30 am in order to get the photograph at dawn; with their softer light and reddish tints, sunrise and sunset are the best times for photography.
