Black rat snake. They grow to be about 5-7 feet long. Mine are very docile, but as we all know 7th graders are very rowdy people. especially when it comes to animals they get to touch.
I think its a wonderful thing that teachers are bringing snakes into class to help educate that snakes arent the "slimy and disgusting" creatures most people see. However I will offer a couple words of advice, to cover your own butt.
Make all the kids get a parental waver consent form before you let them handle the snake. If a kid gets bit, as you say some have, that could lead to a lawsuit - especially if the parent didnt know what was going on. Also 7th graders tend to tell everyone everything, so get it cleared with the principal or whomever needs to be contacted.
make the kids wash their hands before and after handling the snake. Even though a black rat snake is not venemous, if there is a live bacteria on the skin and the kid gets bitten, then it can form its way into the body causing the kid to get sick. Again, another liability.
Also, telling us that the snake bit but seems docile tells me the kids were being rowdy. I'd make a rule that if they got too rowdy, the snake went back in the cage. Make it a reward for good behavior to take time away from studies and get to take the snake out.
If you want some basic care information, check out the care sheet in my signature. It goes over the basics. I'd read all you can find on the subject, and never take one thing as the bible.
