I was schooling my daughter today when I decided to do a science review with her. We've been working on plant science for several weeks. I came to the question of what three things do plants need to grow? She blurts out "water...sun....(pause)." I waited. Daughter turns her head bit to the side and says, "Carbon dioxide?" I laughed good and hard out loud--because she was more than right. I was expecting "air" to be the final answer. That would have been the "correct" and expected response from a four year old. Heck, probably even from a six or seven year old. I know somewhere back in the content of what we've covered, carbon dioxide was mentioned once. No big emphasis on it or anything. Leave it to my girl to pull that one out of the place where all her latent learning is stored until she randomly and unexpectedly demonstrates her amazing abilities to absorb and retain somewhat trivial (but factual) information for later application.
At least she didn't credit this one to SpongeBob.
