Hertz, donut

1- the pictures are of the 2009 baltimore kinetic sculpture race that about 15 of my students and i were a part of this year. i plan on being in this race every year for the rest of my life. 15 miles. mud pits, floating in the dirty harbor, boas and fun socks and more costumes than you could shake a goggle at. SO MUCH FUN.

2-our new unit is on waves and sound. today we were talking about what frequency is, a period is, all that fun stuff. i asked what frequency was measured in, to which the students responded "Hertz." i then asked if they had ever had a Hertz donut. they said no. poor unsuspecting bastards. i walked up to a select member of each class (jabrea, nigel, soren) and asked if they wanted a Hertz donut. they each said yes, and i slugged them in the arm and said "hurts, don't it?" yeah... they had never heard that before. and now i'm assuming there are 8th graders all over the city with huge Hertz donut bruises on their arms.

we also discussed what a "period" is (the amount of time it takes one wavelength to pass a given point). when i asked for students to define it, i made sure to tell them first that no, it was not when a girl becomes a woman. they gave me the right definition. i then asked them what it was measured in.... "is it teaspoons? no... periods are measured in seconds." apparently i'm that gross science teacher. SO many groans and disgusted faces. right on.
