Remembering 9-11

While I encourage my students and parents to read the background of the 9/11 attack at worldbookonline.com or wikipedia.org, there are a couple of facts that I'd like to emphasize.

Osama bin Laden and most of the assassins were natives of Saudi Arabia. The average American probably thinks they were Afghani because many members of al Qaeda were trained in Afghanistan.

"Then why didn't we attack Saudi Arabia?"

We have an uneasy relationship with Saudi Arabia. The overriding fact is that we need their oil. The fact that al Qaeda got most of its money and philosophical support from Saudi Arabians was an inconvenient truth in the post-9/11 war on terrorism.

"Then why did we attack Iraq?" In my opinion, there's no satisfactory answer to that one aside from faulty intelligence and questionable judgement.

Homework in geography class?

The basic and quotidian assignment is not one that my students are accustomed to:
Read the class web site.

Each day I post notes and assignments. It's like a constantly evolving personal textbook. If you keep up with the flow of material it all makes sense. If you print it out and try to read it once a week it can seem incomprehensible.

Reading your class notes on a web site is a skill for now and for the future. More and more teachers will be posting their class marterial on similar sites.


Fri, Sept 12 brings a different sort of homework: a typed essay. Many of my students checked their drafts with me today. Yay. That's the mark of an outstanding worker.

The Caribs: among the first to be enslaved, tortured and genocidally murdered in the New World


carib diorama
Originally uploaded by wesh
Carib, Island Carib or Kalinago people, after whom the Caribbean Sea was named, live in the Lesser Antilles islands, says Wikipedia.

They were among the first people to be enslaved, tortured and genocidally murdered by the Spanish in the New World.

The Caribs were skilled boatbuilders and sailors, and seem to have owed their dominance in the Caribbean basin to their mastery of the arts of war.

The Caribs were themselves displaced by the Europeans, and most were eventually exterminated or assimilated during the colonial period by the Spanish.

Even after Columbus was presented with evidence that the cannibalism of the indigenous people was a myth, the myth was perpetuated because in 1503, Queen Isabella ruled that only people who were better off under slavery (including cannibals) could legally be taken as slaves. This provided Spaniards an incentive and legalistic pretext for identifying various Amerindian groups as cannibals in order to enslave them and take their lands away from them.

Archipelago: a chain of islands, such as the West Indies or Hawaii

Studying the West Indies (Columbus wanted everyone to believe he'd discovered India so he called it the West Indies) means we're studying an a r c h i p e l a g o.

In the Caribbean archipelago, there is an island that comprises two nations, Haiti and the Dominican Republic. Finding the name of that island is not easy. It is known as Hispaniola.

What is the implication carried by the name Hispaniola? The indication is it's connected to Spain or something Hispanic. That's correct. It was named by Columbus for his beloved nation of Spain, or Espana.

Caribs: the native people of Hispaniola and the West Indies

The word "hurricane" derives from the Carib god of evil, Hurican. It is used for severe storms in the North Atlantic and the North Pacific east of the international dateline.

The art of editing the material you read

Editing is a higher thinking skill.

In a class activity involving a series of review questions, the business of editing - compressing - the questions is probably a higher skill activity than the finding of the answer.

It entails:
- Deciding quickly which words are the essence of the question.
- Which words to omit.
- Use of abbreviations.
- A possible re-ordering of the words to shorten the statement.

Exploring the options in regards protection of New Orleans from future hurricane-borne floods


Antoine's Restaurant
Originally uploaded by Alicia-Lee-07
Notes from an article published in 07 called "The Threatening Storm,"
By Michael Grunwald.

* Corps officials have also committed to restoring the surge-softening marshes, cypress swamps and barrier islands that are disappearing at a rate of a football field nearly every half-hour. They say they now understand that the survival of New Orleans depends on a sustainable coast.

* traditional engineering: huge structures designed to control rather than preserve nature. And its latest plan seeks to extend those structures along the entire coast, calling for such massive levees across so much of the state that scientists call it the Great Wall of Louisiana. The Corps says it's just an idea, but Congress is about to authorize the first stretch of the wall--a $900 million, 72-mile (116 km) levee.

* "Fix the Coast, or We Are Toast!"

*
NEW ORLEANS WASN'T ALWAYS A CITY IN A bowl. The French founded it in 1718 on high ground along the Mississippi, a "natural levee" of sediment deposited by the river. That's why tourists in the French Quarter stayed dry during Katrina. And that's how all of south Louisiana was built--by the Mississippi River mutinying its banks and rambling around its floodplain like an unruly teenager, dropping mud around its delta and creating roughly 4.5 million acres of wetlands between New Orleans and the Gulf.

So while the French built an earthen levee 1 mile long and 3 ft. high to block the river's annual tantrums, they didn't bother trying to block the occasional hurricanes that swept up the Gulf. "They didn't need hurricane levees," says Kerry St. Pe, a marine biologist whose ancestors arrived in 1760. "They had wetlands to protect them." New Orleans wasn't on the coast, and hurricanes wilt over land.

* After the vast Flood of 1927, the Corps of Engineers built dams, floodways, revetments and pumped-up levees throughout the Mississippi basin, caging the river in its channel, safeguarding riverfront cities, creating a reliable web of liquid highways.

But by walling off the river, trapping its sediments behind giant dams and armoring its erosive banks with concrete, the Corps inadvertently choked off the land-building process. The straitjacketed river now carries less than half its original sediment load down to Louisiana. So there's little new land-building material to offset the natural erosion of the coast, much less the unnatural rising of the sea fueled by global warming.

* The result is that New Orleans is sinking, and about 30% of the coast's wetlands have slipped into the Gulf, jutting Louisiana's chin even further into the path of Mother Nature's fist, endangering the U.S.'s largest offshore oil and gas fields, a lucrative seafood industry, a busy network of ports and about 2 million people.

* "Basically, we found that none of the levees that failed were protected by wetlands or trees," Mashriqui says. Oil and gas canals have accelerated the land losses. But so have Corps navigation canals, especially the notorious Mississippi River Gulf Outlet, a shipping shortcut to the Port of New Orleans that was a larger dirt-moving project than the Panama Canal when it opened in 1965. The canal never carried many ships, but it has carried plenty of saltwater into freshwater marshes and cypress forests, killing nearly 100 sq. mi. (259 sq km) of wetlands.

* The U.S. has no water-resources policy, just a ready-to-build water-resources agency whose agenda is dictated by an annual funding free-for-all among its 535 bosses - the US House of Reps. It's a classic example of Washington's iron triangle: commercial interests lobby the Corps and their Congressmen for projects that supply the Corps with work and political cover and help the Congressmen steer jobs and money to constituents and contributors.

* Scientists believe they know how to save it. They want the Corps to let go of the river in strategic areas so it can get back to work building land, even if that requires rearranging navigation at the mouth of the Mississippi. They want to fill in oil and gas canals, constrict the Gulf Outlet and start pumping sediment back into ridges and barrier islands. The Corps developed $14 billion worth of Louisiana restoration plans before Katrina, but Bush scaled them back to $2 billion. Now the scientists want to think even bigger about the entire ecosystem, even the sediments trapped behind dams 1,000 miles upstream (about 1,600 km).

New Orleans asks: Will the rebuilt levees hold?


road on the levee
Originally uploaded by Ale*
Students asked about this issue last week in class.

NEW ORLEANS (AP) — Just three years after Hurricane Katrina, New Orleans confronts a new threat from Gustav and a stark question: Will the partially rebuilt levees hold?

levee and drain pipes
Despite $2 billion in improvements, including 220 miles of repaired, raised and replaced floodwalls, 17 new pump stations and more flood-resistant pump stations, nobody can say for sure the city won't be swamped again. And if it is, could it ever recover?

"It's scary, man," said Robert Russell, a 63-year-old plumber whose house in Gentilly Woods is close to floodwalls on the Industrial Canal that are so suspect the Army Corps of Engineers is buffering them with large baskets filled with sand.

"They say it's not up to code," he said. "We'll have to wait and see."

Levee experts and the Army Corps insist New Orleans is safer than before Katrina flooded more than 80 percent of the city on Aug. 29, 2005.

Yet the system still has severe shortcomings: Flood barriers meant only to withstand medium-strength storms, hidden layers of weak soil and navigation channels that inadvertently funnel storm surge into the city, to name a few.

"The positive thing about having any storm hit you, it will reveal any kind of frailty in the system," said J. David Rogers, an engineer at Missouri University of Science and Technology, who's tracked the construction closely. "And we shouldn't be surprised if there is frailty."

Experts estimate the system is only a third of the way to where the corps wants it by 2011 — strong enough to protect against what scientists call a 100-year-storm. That type of hurricane has a 1 percent chance of occurring each year.

By comparison, the corps says Katrina was a 396-year storm, a rare catastrophic hurricane. The agency has not classified Gustav, which was crossing Jamaica Thursday.

"We're not close to 100-year-level protection yet," said Robert Turner, the regional director of the Southeast Louisiana Flood Protection Authority-East. "It's not worth putting your life at risk if you have the means to get out."

Maps by Gerardus Mercator, mid 1500's

The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator, in 1569, says Wikipedia.

It became the standard map projection for nautical purposes because of its ability to represent lines of constant true bearing or true course, known as rhumb lines, as straight line segments.

While the direction and shapes are accurate on a Mercator projection, it distorts size, in an increasing degree away from the equator.

The nature of the Great Circle route


roof
Originally uploaded by trudeau
Great circle routes are used by ships and aircraft where currents and winds are not a significant factor. For aircraft traveling westerly between continents in the northern hemisphere these paths will extend northward near or into the Arctic region, while easterly flights will often fly a more southerly track to take advantage of the jet stream.

A great circle is a circle on the surface of a sphere that has the same circumference as the sphere, dividing the sphere into two equal hemispheres, says Wikipedia.

A great circle is the largest circle that can be drawn on a given sphere. The diameter of a great circle is same as the diameter of the sphere.

When long distance aviation or nautical routes are drawn on a flat map (for instance, the Mercator projection), they often look curved. This is because they lie on great circles. A route that would look like a straight line on the map would actually be longer.

On the Earth, the meridians are on great circles, and the equator is a great circle. Other lines of latitude are not great circles, because they are smaller than the equator; their centers are not at the center of the Earth -- they are small circles instead.

The Mississippi River[2] is the second longest river in the United States, with a length of 2,340 miles (3,770 km)[3] from its source in Lake Itasca in Minnesota to its mouth in the Gulf of Mexico, says Wikipedia. The longest river, a Mississippi tributary, is the Missouri River measuring 2,540 miles (4,090 km)[4].

The Mississippi River is part of the Jefferson-Missouri-Mississippi river system, which is the largest river system in North America and among the largest in the world: by length (3,900 miles (6,300 km)), it is the fourth longest, and by its average discharge of 572,000 cu ft/s (16,200 m³/s), it is the tenth largest river.

The name Mississippi is derived from the Ojibwe word misi-ziibi ("Great River") or gichi-ziibi ("Big River") at its headwaters.

Wikipedia reminds us that "The Atchafalaya River in Louisiana is a major distributary of the Mississippi." What does that mean?

* Reasons for the flooding
* Elevations in New Orleans
* Poverty in the Crescent City
* Map of NO
* Coastal deterioration factors
* Corps of Engineers and the Mississippi levees

Ex: compare the basic facts of Hurricane Katrina and the Galveston, Tx, hurricane of 1900.

This week in geography: how can we compare Facebook to the Mississippi valley?

Ni hau! That's Mandarin Chinese for "hello."

What city lies at 39N, 116E?
a) Seoul, S. Korea
b) Shanghai, China
c) Beijing, China
d) Denver, Co

This week: grids, coordinates and map projections.

While this is a week on the basics of geography, we will also look ahead to our unit on the US.

- The importance of the Mississippi valley network, a non-digital information and social connection system.

How is Facebook like a modern version of the Mississippi valley?

The art of comparison, a higher-thinking theme of this geography class

Typical comparison work in this class will comprise the following elements. Typically, this will be the format for independent work.

- Base your essay on no less than 3 factual items for each topic.
- Open with a colorful, descriptive sentence.
- Switch back and forth between topics, which is called integration of topics. Do not give the info in separate blocks and add a final integration.
- Cite your sources (Wikipedia.org, teacher Robert Trudeau, etc) by the phrase “according to.” Place it at the end of the first sentence of each paragraph.
- Top it with a a) smacky title and b) explanatory subtitle
- Proofread your paper for * legibility * speeling * grammar
- Name, date & hour in upper right corner!
- Proofread one more time.

Ex.: Compare the 2008 and 2004 Olympic Games in regards locations: Athens, Greece and Beijing, China.

Titling: an essential skill in social studies

On every paper you do for this class I will expect you to follow these titling guidelines:

a) Snappy title.
b) Explanatory subtitle.

- Snappy title ex: Roiling on the Red
- tweaks a phrase from pop culture
- uses alliteration

- Explanatory subtitle ex: Mapping the Course of the Red River
- longer and detailed.


Communication in a crowded, busy world is not easy; using vivid titling is a way to stand out from the crowd.

One of the more brutal Cross Sections I can imagine

Cross section maps are fun.

Some people find cross sections of human anatomy interesting, too. Maybe this is your first test in regards medical school. So you think you want to be a doctor, eh?

Map art: the reds & blues of the world ocean currents map

One of my favorite maps is the world ocean currents map. It helps explain weather, crops, climates, sailing and trading.

Find one on p. 63 in the textbook. Or see physicalgeography.net.

- Render and label the continents and oceans.
- Sketch and color these currents:
1.California Current
2. N Equatorial Current
3. S Equatorial Current
4. Brazil Current
5. Gulf Stream / N Atlantic Current
6. Canary Current

Greenwich, England, lies upon the Prime Meridian


Greenwich England
Originally uploaded by dawgfanjeff
The Prime Meridian is the meridian (line of longitude) at which longitude is defined to be 0°, says Wikipedia.

The Prime Meridian and the opposite 180th meridian (at 180° longitude), which the International Date Line generally follows, form a great circle that divides the Earth into the Eastern and Western Hemispheres.

Unlike the parallels of latitude, which are defined by the rotational axis of the Earth (the poles being 90° and the Equator 0°), the Prime Meridian is arbitrary. By international convention, the modern Prime Meridian is one passing through Greenwich, London, United Kingdom, known as the International Meridian or Greenwich Meridian.

This is not the Prime Meridian

This may remind you of the Prime Meridian, but it is, in actuality, a cut of Prime Rib. It is a tender, flavorful cut of roast. Served au jus with a bit of horseradish and fried onion rings it is a sublime reminder of the imaginary line that runs through Greenwich, England.

One day I would truly like to consume a 12 oz. Prime Rib on the Prime Meridian. You, too?

From Amerigo Vespucci, the explorer and cartographer (about 1500). Our continents are named for him.

How did we somehow integrate mention of Leonardo DiCaprio and the Isle of Capri (on the Italian, Mediterranean coast)? The island of goats?

Why, from the Tropic of Capricorn. Basic, my dear.

America's largest crop: corn


Dead Corn
Originally uploaded by joblow
America’s largest crop is corn, says Wikipedia.

Corn is a readily available, reliable, storable and versatile commodity. In the average American supermarket, corn derived ingredients can be found in one-fourth of everything on the shelves.[2]

This includes not only food items, but also cosmetics, toiletries, cleaning products and household goods. Aside from that, corn is also used for the feeding of factory farm animals, for the production of alcohol, and can be used as a fuel source for both heat production and vehicles. On top of being a versatile commodity, corn has been genetically modified in a way that facilitates industrial-agricultural harvesting and large yields.

Between the years 1920 and 1980, US corn yields increased 333 percent and continue to improve.[3] The strains of corn used for industrial farming are engineered to grow in a uniform, perfectly upright fashion that facilitates mechanical harvesting. Corn is also modified to thrive in crowded conditions; one acre of land can accommodate around 30,000 plants and produce roughly 180 bushels of corn, with each bushel weighing in at 56 pounds.[4] Genetic modifications have made it possible for certain strains of corn to be naturally insect resistant.

Cheap and readily available chemical pesticides and synthetic fertilizers have contributed greatly to high crop yields; corn has also been engineered to tolerate chemicals and to efficiently utilize petrochemical fertilizers.[5] Increases in the productivity of corn have helped to keep food prices low. America’s number one crop has an undeniably important place in both the economy and in peoples' diets.

Note-taking skills in social studies class

Recommended practice . . .

- Leaving generous space between items.
- Learning to shorten sentences and to use abbreviations.
- Using sketches to punctuate and illustrate items.
- Using color for accent.
- Underlining key words.
- Asking questions of the teacher when in doubt.

Rain hampers the local corn harvest; what are the implications?

This morning I talked with teacher Margaret Nance about her farm in Dixie. She said the August rains - ordinarily expected in September - were stopping the harvest. The harvester machines cannot work the fields when there is too much mud. She added that the farmers are under contract to deliver their crops at a certain time.

So I asked geography students to write a brief answer to the query "Rain hampers the local corn harvest; what are the implications?"

First, students wanted to know the definition of "implication." It is something that is not stated directly but something that is suggested.

The implications? The price of corn may rise. Many students smartly pointed out that supply and demand might cause the price increase.
Other students said that supplies of Ethanol, a fuel made from corn, might be affected. A few students pointed out that prices of beef and soft drinks and even ice cream might rise because these products are based partly on corn.

All things considered, it gave students a chance to use a higher level of thinking and their background in current events.

Implication? Studious, intelligent, careful

The truth of the matter is that I don't know whether Joseph is studious and careful. He was placed in my class only today. But something about this photo of him implies those qualities.

To imply is to suggest. One must interpret to draw an implication.

Today's question was -
"Corn harvest in Caddo upset by rain. What are the implications?"
Thus we are looking for the things that will happen in the overall marketplace as a result of this slowdown in harvesting this important grain.
