One day doesn’t cut it anymore — there’s enough fouling of our planet to require an entire month of concern. Some say that’s not enough.
Here’s EPA’s Tip of the Day for today, April 13, with information on how you can listen to EPA podcasts and subscribe to the Tip of the Day feature:
Tread lightly! Use public transportation, carpool, walk, or bike whenever possible to reduce air pollution and save on fuel costs. Leaving your car at home just two days a week will reduce greenhouse gas emissions by an average of 1,600 pounds per year. If you can work from home, you’ll reduce air pollution and traffic congestion – and save money. Play the podcast (MP3, 788KB, runtime 0:47) | Reduce your carbon footprint.

Here’s another opportunity to put real, cutting edge technology in your classroom. In fact, your kids could probably invent all sorts of new uses for it.
Have you even heard of this stuff? Can you use it, live, with the equipment you’ve got?
Blaise Aguera y Arcas of MicroSoft demonstrated augmented-reality maps using the power of Bing maps, Flickr, Worldwide Telescope, Video overlays and Photosynth, to an appreciative and wowed audience at TEDS:
My prediction: One more advance in computer technology that classrooms will not see in a timely or useful manner.
But have you figured out how to use this stuff in your geography, history, economics or government classes? Please tell us about it in comments. Give examples and links, please.
It’s not exactly family safe, so I’ll link. For a college class, I’d ask students to determine if the piece is accurate, and if not, what really happened.
Pulitzer Prize-winner Tom Toles in the Washington Post, March 19, 2010
It’s pretty embarrassing when the State Board of Education’s actions leave Texas open to jokes about whether Texans remember the Alamo. Remembering the Alamo is as much a Texas monument or icon as anything else — maybe moreso.
Tom Toles demonstrates why Texas should be embarrassed by the Texas State Board of Education’s work on social studies standards.

Clay Bennett, Chattanooga Times-Free Press, March 16, 2010
Bennett remains one of my favorite cartoonists today. His work is incisive, intelligent, and persuasive to the side of reason and light almost all of the time. Why hasn’t he won a Pulitzer yet?
Bennett is generally a powerful supporter of U.S. education; see the two other recent cartoons, below the fold.
The first one featured pure crankery, often, from Christopher Monckton and Steven Milloy, two people who have made careers out of pissing in the soup of science. The second conference pretended warming isn’t happening (the title of the conference was). The theme of the third conference is “Reconsidering the Science and the Economics,” but you’d have to be complete fool to think the Heartland Institute would allow a reconsideration of their misplaced sniping at science and bizarre claims that we cannot afford a healthy planet (we can’t afford an unhealthy planet!).
Watts’s topic will be “Is the U.S. Surface Temperature Record Reliable?” It should be a remarkable presentation.
If the surface temperature record isn’t reliable, what’s he doing using it every day in his weather forecasts? If it is reliable, what’s he doing attacking scientists for using it, and where does he propose to get better, more reliable data?
You can rely on this: There will be lots of press releases, but precious little science that has gone through any peer review process to provide reliability.
In fact, now would be a great time to brush up on Jeremy Bernstein’s methods for telling crank science from genius, and Bob Parks’s “Seven Warning Signs of Bogus Science.”
I’d love to have the concession to sell the “Bogus Science Bingo” cards at the meeting.
Chicago in May can be delightful. Cooler days do not get so cool. Spring flowers still erupt. Warmer days will invite outdoor dining downtown and at Chicago’s great neighborhood restaurants.
But these guys will stay indoors and carp about science, about imagined conspiracies to keep their words of wisdom out of publication. Most of them will have some corporate or PAC group paying their way, but a few people will pay to see this parade of voodoo science. They will be had by all.

The daffodils are lovely — I recall when they’d bloom just about Easter in Utah, and Washington, D.C. Here in Dallas, our daffies depart before March 15, often not bothering to stick around until Easter.
But the real treat is the tree in the background. It’s just another tree early in the spring, not yet leafed out. But this one is special.
Pterocarya fraxinifolia (tree in the background) – common name, “caucasian wingnut” – in the Warley Place Nature Preserve, in Essex, England. Photo by Glyn Baker.
Its common name is “caucasian wingnut.” You can’t make this stuff up. Reality is always much more entertaining than fiction.
Another species from China, the Wheel Wingnut with similar foliage but an unusual circular wing right round the nut (instead of two wings at the sides), previously listed as Pterocarya paliurus, has now been transferred to a new genus, as Cyclocarya paliurus.
Uses
Wingnuts are very attractive, large and fast-growing trees, occasionally planted in parks and large gardens. The most common in general cultivation outside Asia is P. fraxinifolia, but the most attractive is probably P. rhoifolia. The hybrid P. x rehderiana, a cross between P. fraxinifolia and P. stenoptera, is even faster-growing and has occasionally been planted for timber production. The wood is of good quality, similar to walnut, though not quite so dense and strong.
Japanese wingnuts? Chinese wingnuts? Tonkin wingnuts (for all you Vietnam war historians out there)?
A 7.2 magnitude earthquake has hit the Mexican peninsula of Baja California, killing at least one person and causing tremors as far away as Nevada.
The quake struck at 1540 (2240 GMT), 26km (16 miles) south-west of Guadalupe Victoria in Baja California, at a depth of 32km, said the US Geological Survey.
Some people are still trapped in their homes in the city of Mexicali, where a state of emergency has been declared.
It was the worst quake to hit the region for many years, officials said.
The US Geological Survey said some 20 million people felt tremors from the largest quake to hit the area since 1992.
My students with Mexico connections tend to come from farther east, and higher in the mountains — I don’t think I have a single student who visits Baja California on breaks. But the news will prompt questions from them tomorrow.
A magnitude 7.2 earthquake occurred at 3:40:40 p.m. (local time at the epicenter) on Sunday, 4 April 2010 in Baja California, approximately 75 km south of the Mexico-USA border. The earthquake occurred at shallow depth (approximately 10 km) along the boundary zone between the North American and Pacific plates. Since earthquakes have been recorded instrumentally, only two similar sized earthquakes have been recorded in the area. The first was the 1892 earthquake estimated at magnitude 7.0-7.2 along the Laguna Salada fault just south of the USA-Mexico border. The second was the 1940 Imperial Valley magnitude 6.9 earthquake which occurred in southernmost California. Today’s event is located nearly in line with these earthquakes along the plate boundary, but is situated farther to the south. There are several active faults in the vicinity of today’s earthquake, and the particular fault that generated this quake has not yet been determined. Faulting is complex in this region, because the plate boundary is transitional between the ridge-transform system in the Gulf of California and the continental transform system in the Salton Trough. Most of the major active faults are right-lateral strike-slip faults with a northwest-southeast orientation, similar in style to the San Andreas fault to the north. Other faults in the vicinity with the same orientation include the Cerro Prieto fault and the Laguna Salada fault.

What other questions can we anticipate? Somebody will ask whether this quake is related to the Haiti and Chilean quakes (probably not closely related). Somebody will wonder about the Pacific Ring of Fire, and this quake’s relation to volcanoes and general earthquake activity around the Pacific (high relationship). Someone will want to know about quakes in your area. Is this the precursor to “the Big One?”
The USGS site is a good place to start on all of those questions.
In a discussion of the Cold War, the Space Race, and the Race to the Moon, we get to a photo about Apollo 11’s landing on the Moon.
Like clockwork, a hand goes up: “Mr. Darrell, wasn’t that landing a hoax? They didn’t really go to the Moon then, did they?”
There are a lot of ways to know that Apollo 11 landed on the Moon. Among other things, students could talk to people alive at the time who have the slightest bit of technological savvy: With lots of other people, I tracked part of the trip with my 6-inch reflecting telescope. Ham radio operators listened in on the radio broadcasts. And so on.
But I really like this chunk of evidence: How about a photograph of the landing site?
Holy cow! You can see the tracksof Neil Armstrong’s footprints to the lip of Little West crater (see arrow below).

The astronaut path to the TV camera is visible, and you may even be able to see the camera stand (arrow). You can identify two parts of the Early Apollo Science Experiments Package (EASEP) – the Lunar Ranging Retro Reflector (LRRR) and the Passive Seismic Experiment (PSE). Neil Armstrong’s tracks to Little West crater (33 m diameter) are also discernable (unlabeled arrow). His quick jaunt provided scientists with their first view into a lunar crater.

My blog, Millard Fillmore's Bathtub, is a continuing experiment to test how to use blogs to improve and speed up learning processes for students, perhaps by making some of the courses actually interesting. It is a blog for teachers, to see if we can use blogs. It is for people interested in social studies and social studies education, to see if we can learn to get it right. It's a blog for science fans, to promote good science and good science policy. It's a blog for people interested in good government and how to achieve it.
