Day 163: Tinkerers Wanted
Not satisfied with the paper strip "conveyer belt" I suggested students use, one group wanted to make a real conveyer belt for yesterday's investigation. (They actually built this a few days before when I showed the "I Love Lucy" candy factory clip.)
It took them about a half-hour. They were testing, failing, adjusting, repeating. And when it finally worked, the look on their faces was glorious.
I wish others would tinker, too.
