Tonight, as I understand it, “After Armadeddon” will air at 8 PM on the History Channel. It does present interesting opportunities for science teachers to talk about student ideas and feelings related to future and past disasterous conditions on Earth. It is part of a week of disasters at the History Channel. Here is a description of the show:

After Armageddon: – 08:00-10:00 PM

What have past acts of destruction taught us about what will happen to mankind after the apocalypse? Is it inevitable that disaster will someday strike America on an unprecedented level? How has history prepared us? History’s most dramatic events–Hiroshima, 9/11, Hurricane Katrina and others–are examined and analyzed with hard data gathered from their massive aftereffects. The disappearance of water and food supplies, the effects of deteriorated sanitation and health care on the remaining population, and the increased use of violence as a means of survival–all illustrate how societies have responded and survived.

I have an especially keen interest in this show as my son, Hy Rillero, spent just over two-weeks filming his segment, with many long days of work. I am hoping that much of his vignette survives the editing process for this two-hour special. No matter what happens it was a great experience for Hy to work with Director Stephen Kemp (Raw-TV). In Hy’s section, a respiratory virus has wiped out 80% of the US population and he chronicles his family’s quest to survive.  The photo is of Hy and his film mom and dad.

Wordle is a tool for displaying words as a graphic image that has implications for science education. The size of the words is a relative indicator of their frequency of use. At the Wordle website I entered the URL for this blog, and received a JAVA-produced image. This image is presented above.

Wordle was developed by Jonathan Feinberg who has produced other science education tools including physics applets and the Secret Lives of Numbers.

Software applications seem to be a creative playground for Feinberg in that he produces what he is interested in and let’s others play with them depending upon their interest. I think Wordle is the most promising classroom tool he has created. But of course, he leaves it to us science educators to explore how to use the tool.

I have just completed 11 days of electricity explorations with a middle school class. I put the text for all my lesson plans into Wordle’s create page and it produced an interesting word art graphic. Teachers will have to take a screen shot of the image to share it with students. (Macintosh: command-shift-4 produces cross-hairs to capture the image, which then appears on your desktop.)

It was interesting to see words such as day, one, and two appear prominently. In checking the word count (see image to left), I realized how often I used the term “one” (apparently it is found in terms such as “someone” as well as pure uses) as I had it over 40 times. These words are not related to electricity, so in MS Word, I deleted (through find and replace) these terms and redid the Wordle image. It is presented below. I will share the image with my students for their review and reaction. It does present an interesting way to view key vocabulary in science. 

I am excited by the potential of Wordle as I stand along the shore. Teachers can make their own “Word Art” or borrow creations of others. There is an ocean of potential waiting to be explored by creative science educators.
