Using video in the classroom can engage students and bring lessons to life. Video can be integrated into lessons from sources like YouTube and Discovery Education, or teachers can record their own videos using tools like Google Hangouts, Skype, and various iOS apps. Videos can be added to slides in PowerPoint, Keynote, and Google Presentations to show concepts rather than just telling students. Video chat options like Google+ Hangouts on Air allow for live interaction, while services like Animoto and Capzles help create visual timelines and movie trailers to illustrate lessons.
