Another thought...with that many students there are bound to be students with children of various ages. As the developmental section nears, ask for parents to volunteer their kids if they are comfortable participating in an experiment, and use them to demonstrate conservation, Kohlberg's moral dilemma (modify it to stealing a cookie, or something like that and as what they would do and why), even object permanence (play peek-a-boo) if with a baby.
I use clear glasses and blue water (tint with food coloring so it shows up better) to demonstrate conservation. The first child was 6 - right on the border for Piaget's age labelling. His mom was one of the brightest students in the class. I thought he'd surely get the conservation concept right and then I'd have to stress that Piaget might have been wrong about the ages. (I did talk about that later, of course.) I held my breath because it makes for a less than memorable demonstration if the child has no difficulty pointing out that the amount is the same, etc. Sure enough, God bless him, he insisted that, "Now this glass holds more water." I'll never forget him. He was so cute - and so sure. I think his mother was stunned. A fun, memorable demonstration.
