I did the project with the kids to see what was involved, and I told them it was the first time I'd done this, so we'd learn the pitfalls and tips and such together. I also was vague on how they should display the projects at the end. I said, "wow me" and "whatever you do, have a good reason for it" and "think of the best way to display it to use as a learning tool".
The general idea was that we'd all have the same starting 2-dimensional region (y = 4 - xx), and we'd each revolve it around a different axis of revolution, and thus each have different solids at the end.

Yup, they basically all looked like these. I wasn't happy with the scale differences. We had to adjust for the thickness of the foam, so the x- and y- axes had different scales, and different students picked different ones. So even though we all had the same function, they were "distorted" from each other. ... but that's a minor thing.
