Atomic Mass

Oh my chemistry class.
The topic: Parts of an atom (protons, neutrons and electrons) and the periodic table.

The activity: The kids are asked to count the number of protons (symbolized by black circles) and neutrons (symbolized by white circles) inside the nuclei of several drawings of atoms.

The comment: “Yo, Yo, Ms!!!! (fits of laughter and shoving) Evan wants to know what his atomic mass is if he has 2 little black balls in his center.”

What I say: I don’t know, does he have any neutrons?
What I am thinking: Well, gosh, does he have any little white balls, because if he does, maybe you should take him to the nurse.
