| May 16, 2012 at 3:42 | comment | added | senderle | When I was in the third grade, I saw a documentary on television about stars, which discussed plasma. I knew enough about the structure of atoms to understand its description of plasma as a fourth state of matter. When my teacher gave us a test that asked us to list the states of matter, I listed four: solid, liquid, gas, plasma. When he marked my answer wrong, I objected, and my teacher explained that when you think about it, plasma is really just an especially thick liquid. The cognitive dissonance that ensued made me who I am today, and I am thankful for it. | |

Made my first paragraph more polite.

| May 13, 2012 at 16:22 | comment | added | Ellie K | @J.M. mentioned that children should know that adults can sometimes be wrong, too. I agree with J.M. but it is very context-dependent, and usually with different sorts of subject matter than math, or much more blatant "wrong-ness* in a math answer. | |
