“I think one of the advantages that we have as chemistry teachers is that our subject nature lends to always being able to show them something interesting, or something that does not make sense — discrepant events — and we try to ask them — why? And getting from there down to molecules interacting with each other and the forces between them. We could always pull something out of the hat, I mean, a lot of what we are doing in demonstrations in chemistry is like magic for the kids, and kids are fascinated by magic, anyway. And it’s getting that to draw their interest, and to go on from there and talk about the level of what is really going on and get down to the chemistry of it. We can always show them something fun and interesting.”

“So much of the stuff you do on the tabletop is somewhat inconclusive: you show them something green changing into something yellow and you tell them this is a compound and this is an element. How do they know that it is not the other way around? And so I think that the idea of smallest and smallest piece is not something that you could show them on the tabletop, and that’s kind of the point.”
