Cory Doctorow wrote an entertaining novel for this age group in which students were given ID cards like these after a terrorist attack. They found many interesting ways to mess with the system pretty quickly. The book is called Little Brother.

Please don't place such a condescending stereotype on conservatives. I believe myself to be quite conservative, but I've read Ender's Game and Ender's Shadow (I will finish the rest as I have the opportunity). A colleague of mine at a small midwestern middle school assigned Ender's Game to his students and they read it together in class. He also taught Sunday School at a small conservative church. He received no backlash from parents.
    And to say that conservative literature and ideas are embraced by those who are "less intelligent" is intolerant and hateful. (See what I did there? Those are "Liberal" attack words.)
    Even though I am a conservative parent and teacher, I can't wait until my children and students are capable of thinking for themselves. As a teacher, I don't see success in test scores, I see it in students' abilities to synthesize information, to discern good information from crap, and to be able to reason through new and challenging situations on their own. But I do occasionally encounter parents who fear a child who can out-think them, or succeed where they failed. It is unfortunate, but it isn't restricted to conservatives. There are people with very liberal ideologies who fail to see the benefits of proper education.

I thought those were the REQUIREMENTS for a YouTube post! Is that what I've been doing wrong?

Most of the doors to secure areas where I work have the same combination. Real secure! Every time I enter a door I think of that line. People wonder why I smile at work.

billions. 8.1 annually if I remember right

There's also the problem of ounces (weight) and ounces (volume) . That concept isn't reinforced in enough classrooms. Then you have to have dry measuring cups, liquid measuring cups, and spoons and it gets to be a confusing mess. My wife likes to use a scale, until I met her, I never knew anyone with a scale in the kitchen. Now I don't understand why it isn't more commonplace.

I keep refreshing, but there are no comments. How am I supposed to learn anything about this subject if there are not comments?

That would be the absolute coolest thing in the world. I've been a long time fan of the darksucker theory, to have an actual darksucker would be extremely fun. Lots of applications in a physics classroom.

Here. They can make paper out of kangaroo poo, just take it the next step. Take the initiative and your name can be here in an article on Slashdot as the inventor of poop based accelerometers. http://www.treehugger.com/files/2005/12/roo_poo_is_stat.php

If she's pretty enough, there are plenty of guys here that will believe anything else she wants to tell us!

This could have worked the other way. If she had been in a crowded bus when receiving the text, and ended up heading to an area that wasn't as crowded as she had hoped, it could have been the opposite, and no one would have been wiser. Random texts or half rings would irritate more than save lives. You can never be sure that the bomber isn't in a preschool dropping off her kids before going to blow up somewhere else.

Or, just patch it through to an external loudspeaker...

Hey, my girlfriend once stopped over at one of our lan parties. She stayed a whole 3 minutes too! So there.
