This is perfect for Halloween in a reading or English course.
This project belongs to a complete unit that I use with my 7th graders to teach the following components:
Presentation skills (Speaking and Listening)
Reading Informational Texts
Ethos, Pathos, and Logos
The students love to take on the role of cryptolozoologist and research their favorite monsters; for reluctant learners, this is an excellent project. As the complete unit has students creating several presentation opportunities and we've worked extensively at perfecting the group work process, I usually give students three class periods to finish this. For someone using this as a stand-alone project, I would allot a week.
The rubric is included with this, and I will be releasing the full unit soon.
I recommend using Prezi if you want to limit the format that students use.
