As a teacher, I don’t give grades. I’m more or less a babysitter for the teachers! We still go thru all of the fundamentals, just no grades. I run a big fundraiser each year and have been a coordinator for the American Heart Association’s Jump Rope for Heart/Kid’s Heart Challenge for 22 years.
I re-watched the National Geographic documentary on 9/11 on Friday. Heat resistant coatings were separated from the I-beams in the WTC when impacted by a 63-ton object moving at over 500mph. 2,000 degree fire will degrade the strength. Since the second impact was lower, more weight to create the fall. The towers were perfectly straight and of tremendous mass, not like me dropping a tree. It's physics, and any idea that there were folks in that building setting charges during the mayhem and while first responders were heading up is scandalous.
