The Discovery Kids Effect

So C1 got a rocking gift from his grandma last week:  a huge stack of Discovery Kids magazines that they were cleaning out of a 6th grade classroom!  He has been in heaven.  It is funny to hear the things that he takes away from exploring these magazines.  Yesterday on the way to school we were listening to the song "The Farmer in the Dell" and at the end he says "The cheese could take matter and then matter could take an atom!" Which was then followed by a lengthy discussion about why atoms are the smallest units of matter...and I honestly wasn't sure about how to count electrons and other particles...
