Shed skins are pretty fragile, so you'll have to caution those handling them that they tear easily. I usually end up giving them out as souvenirs & kids love it.![]()
Yes, obviously you only take snakes that you know are calm with handling, & there's nothing wrong with taking a bottle of hand sanitizer.
You mentioned this is for young children, right? What our local children's librarian set up one year worked very well; little kids have a short attention span, so several
activities were planned: first she read them a story (about a snake), then they heard about snakes from me & met some of mine, then they did some coloring & paper
crafts afterwards that were snake-themed. You might coordinate something like this with the teacher, with adjustments for the ages you're dealing with.
