"You go talk to kindergartners or first-grade kids, you find a class full of #science enthusiasts. They ask deep questions. They ask, "What is a #dream, why do we have #toes, why is the #moon round, what is the birthday of the #world, why is #grass#green?"These are profound, important #questions. They just #bubble right out of them.You go talk to 12th graders and there's none of that. They've become #incurious.Something terrible has happened between kindergarten and 12th grade." #CarlSagan
