It's Rubbing Off

John and I are in the midst of magnetism experiments with Jet's class an in a lull, John asked the kids what they thought the smallest magnet might be. The kids said that iron shavings seemed to work, and on that order for a while when Jet popped up and said, "Two atoms."

John said, "Pretty close... one atom works, too."

But it was just really surprisingly cool that Jet intuitively went to the atomic level rather than just the visible level.

Science, Spinning, and Postcards

Had a pretty jam-packed science setup today, with an experiment where the kids got to figure out the setup and they got to figure out what prediction really means with some data to start with. It was really fun to introduce the concepts of why standard approaches are necessary and what kinds of things make them good.
