Manatee Fantasea Road ShowHow Slide Show is Used.• This program is used with a third-grade, in-classroom presentation. Students
act as reporters at a news conference where a manatee (puppet is used) is interviewed. Students are provided with questions and these slides support the scripted questions/answers.
• Questions/answers provide students with information about manatees, their habitat and endangered status. They also provide information about adaptation and help students understand adaptation better.
• At the conclusion of the scripted questions, students may ask their own manatee questions.
• The first opening slides are used to be sure students understand the pronunciation of the scientific name for manatees and review their understanding of what an adaptation is.
• Script for slideshow was originally developed by Monica Dorken and this slide show was developed by Eileen Tramontana.
