It's easy to create a Photo Collage of images from Google Drive or Google Photos
You can insert videos for students to watch instead of sending them to YouTube
Or even just view videos you uploaded directly to Google Drive!
You can embed a full size Google Document into a Google Site and change editing rights so everyone can edit if you need a quick and easy way to gather input. Users will select the "pop-out" icon in the upper right hand corner to access the document. Monitor the submissions!
Change the ending of the URL of the Google Document to force students to make their own copy of the assignment but embed the original so they can view it! Example:
To this URL: (notice how the end of the URL is different)
