This is one of the saddest blogs I have ever read. Sad because EVERY child in my class knew what tree acorns grew on. Our teachers had fall decorations with leaves and squirrels and acorns stapled to the seasonal decorations board. Nature was not ignored. Nature was not portrayed as evil or a nuisance as it is today.
Acorns come from oak trees. And you can eat them, too.

Great post, Dolphin. It is alarming to hear that youth, and teachers, don’t know where acorns come from! I did have a chance to taste traditionally prepared acorns in California years ago. I would guess it’s an acquired taste born of necessity, though. 🙂
