my sons science teacher has a corn, some type of lizard, and we bring our biggest ball a few times a year. he feeds his corn live, in class, and has fed our ball in class as well. he is a high school teacher, and there has never been a problem...the elementary school however wouldnt let us bring him into the building do to the younger childrens fears <and administration imo> we live in wi, and i was very impressed at the high school for their openness, and willingness to learn about reptiles. if you want contact info, pm me and ill pass along the info to the teacher...
