Watching someone doing it I mean. My kids just spent half an hour in the backyard watching a spider making a web in the grass. At one point, Chad came running in to tell me the spider had perched on a high point, balled up a great wad of web, and flung it to an area he wanted to go next. This from a kid who's so creeped out by bugs he won't even touch one that he knows is dead.
Isn't it great when they take the initiative to observe and learn without your coaching?
