Join Us! 2021 CEFF 4 Classrooms Virtual Festival Info

Join us ONLINE for the first-ever CEFF 4 Classrooms Virtual Festival!  Specially programmed with students (grades 4th-12th) in mind, this FREE youth film screening will take place during our extended festival from February 12-21, 2021!  Stream the films when you and your students have time during the festival week and then join us for a special live educational event Friday, February 19th from 10:00-11:30 am.



What: Enjoy a 1.5 hour screening of a variety of youth-friendly environmental films, selected from over 130 submitted films this year.  Watch the films when it fits your class schedule anytime between Friday, February 12th and Sunday, February 21st. Selected films will range in length and subject matter. CEFF 4 Classrooms will also include a special live Q & A session with filmmakers and other experts on Friday, February 19th from 10:00-11:30 am! Watching the films prior to the live event is suggested but not required.

How: Films will be screened on our Virtual Festival Platform – Eventive. We encourage you to screen the films with your students. Each teacher will receive free digital unlock codes (1 for the teacher if in-person learning or one per student if remote learning). You may either stream the films in your classroom from the Eventive site (in-person learning) or give students a unique digital unlock code to watch independently (for distance/remote learning). We do have a limit of free unlock codes we can provide, so we strongly encourage you to work as a group (in-person if possible) to allow for the most number of students and classrooms to enjoy CEFF 4 Classrooms this year! Contact us if you would like more details or want to talk through the possibilities. We will provide detailed directions and technical support to all classrooms registered.

Extras: Each teacher will receive a resource package as well as 1 free unlock code to access another film screening session during the festival.
