Note: I purposefully don't tell them that the higher the atomic number of the element, the more candy they get to eat. If they're clever enough to figure that out before the activity, great, but if not, too bad. Nobody complained about not getting equal amounts of candy....well, probably because they were getting to eat candy FOR A GRADE. I'll take you through the process. \
I also modeled and did a think aloud (TAP strategy) as I modeled the construction of a hydrogen atom that I kept available for them to look at or use as needed.
