My kids apparently do.
At dinner tonight:
Harry: Do you know what element has the atomic number 92?
Me: Um, no. Not really.
Harry: It's Uranium
The conversation went on from there. As Harry and Pippi discussed different elements and which ones were their favorites.
Me: You have favorite elements?
Harry and Pippi: Of course.
Now, Pippi is in sixth grade and is doing a unit on chemistry, but Harry is in third grade. They are not studying chemistry. So I asked "How do you know these things? And why?"
Harry: It's what I do in my spare time.
Okay then. (Turns out his binder has a science divider with the periodic table of the elements on it.)
His great-grandpa with a doctorate in Chemistry would have been so proud.
Oh and for the record their favorite elements are: Pippi: Unununium, Harry: Magnesium
