Big Astrobiology Discovery

November 30th, 2010

I’m super-excited about the oxygen find on Rhea (go, Cassini!), one of Saturn’s moons.

I’m even more excited by whatever announcement NASA will make about a discovery that will change the search for extraterrestrial life. Here’s the news blurb:

WASHINGTON — NASA will hold a news conference at 2 p.m. EST on Thursday, Dec. 2, to discuss an astrobiology finding that will impact the search for evidence of extraterrestrial life. Astrobiology is the study of the origin, evolution, distribution and future of life in the universe.

The news conference will be held at the NASA Headquarters auditorium at 300 E St. SW, in Washington. It will be broadcast live on NASA Television and streamed on the agency’s website at http://www.nasa.gov.

Participants are:
– Mary Voytek, director, Astrobiology Program, NASA Headquarters, Washington
– Felisa Wolfe-Simon, NASA astrobiology research fellow, U.S. Geological Survey, Menlo Park, Calif.
– Pamela Conrad, astrobiologist, NASA’s Goddard Space Flight Center, Greenbelt, Md.
– Steven Benner, distinguished fellow, Foundation for Applied Molecular Evolution, Gainesville, Fla.
– James Elser, professor, Arizona State University, Tempe

Those are some big names in science, especially Elser and his life stoichiometry focus (how chemicals show up and balance in living things). The news conference should show up here (around noon Arizona time).

I hope this announcement is bigger than the Beatles being on iTunes.

Sonoran Desert Resources

Here are some great sites to use for information in Ms. Kulkarni’s Sonoran Desert Ecology Project:

For images, our district recommends a Bing search.

Science Limericks

September 10th, 2009

To set up your hypothesis
Make an informative guess
For what you will try
To be like Bill Nye
And live a life of success.

Limericks have a specific structure for rhyme scheme and rhythm.

The rhyme scheme is
A – hypothesis
A – guess
B – try
B – Nye
A – success

So in the sample above, notice that hypothesis and guess rhyme, try and Nye rhyme, and then I bring the rhyme back to success, rhyming with hypothesis and guess. Limericks need to stick to the AABBA rhyme scheme to be a traditional limerick.

For the rhythm part, to keep it simple let’s just say that lines 1,2, and 5 are the longer rhythms and 3 and 4 are the quicker rhythms.

Tradition has it that limericks started out in Limerick, Ireland (sounds believable enough) and that the poems have their roots in a certain type of song.

Here’s a brain-teaser limerick from Kay DeVicci and aps.org:

The sum of 3 numbers is 4;
The product is (-2) more;
The sum of their squares,
If anyone cares,
Is just 14 less than a score.

Switch Zoo

September 8th, 2009

Photobucket
Have you seen Switch Zoo? It’s a great place for a quick writing assignment. Think about focusing on Ideas and Content from the Six Traits. You can have the students create encyclopedia entries for their created animals. It would also be a useful prompt for a diamonte poem, with one creature being the top of the poem and the other creature being the bottom.

The site has some fun games to teach science, as well. I can see students having to provide a rationale for why their animal would reside in a specific biome.

And who doesn’t like learning how to make balloon animals?

Perseids

August 11th, 2009

If you want to see some meteors, tonight the Perseids will be streaking through our sky around midnight.

Perseids being connected to the Perseus constellation…Lightning Thief, anyone?

Interview with Mike Collins, Apollo 11 Astronaut

July 22nd, 2009

Mike Collins was the guy orbiting the moon while the other two operated the landing module. There’s an interesting interview that was posted at NASA.gov to avoid lots of people sticking microphones in his face for the anniversary. Here’s a quote from him about his role:

This venture has been structured for three men, and I consider my third to be as necessary as either of the other two. I don’t mean to deny a feeling of solitude. It is there, reinforced by the fact that radio contact with the Earth abruptly cuts off at the instant I disappear behind the moon, I am alone now, truly alone, and absolutely isolated from any known life. I am it. If a count were taken, the score would be three billion plus two over on the other side of the moon, and one plus God knows what on this side.

We Choose the Moon

July 17th, 2009

It’s what Apollo 11 might have looked like if we had all of the tech to do status updates to give instant updates.

As of my writing Apollo 11 is at Stage 6, half-way between Earth and the moon. If everything stays according to plan, we should see a landing around, oh, I don’t know, July 20-ish.

At the site it not only has the countdown and the visualization, but it’s also streaming all of the dialogue between Capcom (Mission Control, not Street Fighter) and the astronauts. (Click on those links to follow them on Twitter. I set it up for text updates – so that I feel like I’m someone so important the astronauts feel the need to text me.)

In the bottom right of the site is what puts it all into context. Scrolling are fun facts about 1969, like how gas was 35 cents a gallon or how Slaughterhouse 5 was on the New York Times bestsellers list.

You definitely have to check out the video and photo galleries. After 40 years there is still media that I haven’t seen before. It’s all sponsored by the JFK presidential library. I think it’s really cool and for that I give you JFK’s moonshot speech:
