We had a blast with our homeschooling friends at the Sony Wonder Technology Lab, learning about and playing with robots, photo editing, haptic devices (a heart surgery simulation), animating characters and background scenery, and I forget what all else. It was fun and free! But insanely crowded.
Afterwards, we went to a talk by experienced homeschoolers, who shared their wealth of experience about New York paperwork and how kids learn. While the moms (and a couple of dads) talked, the kids enjoyed the garden.
