Mr. Sweetser sprinkled “chemical humor” into the content of his classes in the form of groan-worthy puns, playful interaction with his students, and tangential musings about Shakespeare and best ways to skin a cat. I faithfully jotted down his “Sweetser-isms” in the back of my wide ruled, one-subject notebook all year long, and if (very distant) memory serves me correctly, I think I read aloud an abbreviated version of Mr. Sweetser’s greatest hits on our last day of class, just so he knew how appreciated he really was.

Mr. Sweetser taught me that a teacher’s enthusiasm for their subject matter, coupled with humor and empathy for their students, goes a long way in a classroom! If I could retake any high school class, it would be chemistry with Mr. Sweetser. At least I have this memory of his witticisms and gentle humor to remind me of an excellent teacher. Here they are in their full glory: 86 puns that made me love my high school chemistry class!
