This resource can bring manatees into your classroom. The staff at the museum will set up time to Skype with them and students can see the manatees in real time and speak to the staff that takes care of them. You can tailor your visit by talking to the Education Department. It can be a source of information for student or class research projects.
I have done a virtual field trip for the past few years. Our Manatee club raises money for the endangered manatees and we send our donations to benefit Snooty and his friends at the Parker Aquarium.
