I would call, normally you have to register on there site through the volunteer section if they have availability...and I believe under 16 needs an adult volunteering as well...I know my daughter is 12 and can only volunteer on kid/family days due to her age...but I would call and they could answer all those questions...good luck! It's a great place to volunteer!
High school does in groups but not sure on middle school
They could but upu would have to give them a call in the morning to see how to go about it. Now they are closed .. they have to register somehow .
