Hello,
Free Ride has this exciting partnership with City High School in Pittsburgh in which we teach bicycle repair in a "How Things Work" Physics class. 
We had some lessons with tire pneumatics and Boyle's law and also a gear ratio lesson.
I was wondering if people had other science related curricula planned? If so can you e-mail me or put it on the wiki?
Also, I don't know if people know already but the Youth Bicycled Education Network has some useful curricula posted-- http://www.yben.org/category/resource-guide/curricula-and-lesson-plans/

Thanks,
Andalusia

P.S. I'm not sure if people know what Ghost bikes are- but they are pretty powerful memorials for cyclists who have died.  There was a memorial ride in NYC last week to honor the 23+ cyclists who died last year and I did a radio report about it and wrote an article for those interested
