Now that Google Apps for Education has unlimited storage you should fill it up with video! I use the Snagit Chrome extension to create screencasts that are automatically saved in Google Drive. (Click Here for Extension. Click Here for Snagit App. You need both!) I suggest you set your sharing settings on the TechSmith folder to anyone with the link can view so you do not accidentally share videos that do not have sharing permissions.

Double click to launch the video. The video shows in preview mode.
