Happy Square Root Day!
These days don't come along very often. The holiday dates back to (any guesses?) Sept. 9, 1981 and was started by a high school teacher in Redwood City, Calif. We'll have to wait until April 4, 2016 for the next one. I hope you are doing something special today to celebrate the occasion. That is unless you are saving your energies for March 14 -- international Pi day, of course.
Have any of you teachers marked either occasion in your classroom?
Last Oct. 23, some chemistry students decorated Fairfax High School's hallways to commemorate Mole day. Mole day celebrates a basic measuring unit in chemistry (6.02 X 10^23) known as Avogadro's Number. Dozens of web sites offer suggestions for how to celebrate the day and -- by extension, science -- by eating molasses cookies and telling mole-related jokes.
Q: What did Avogadro teach his students in math class?
