Yesterday Google added the ability to insert a video into Google forms. All you need to do is to go to the "insert" tab and then go down to "video" and then find it on Youtube. Alternatively you could watch this one minute video to do it. It is a great way to give your students a flipped video and then give them multiple choice or short answer questions.
By the way it does not yet work in Google Apps. I should add that Google Apps are always behind the free Google Drive due to the fact that Google Apps just gets things later and school systems in general have to decide whether or not to turn something on for its students/staff and there are a lot of considerations in that prospect which is why I put my materials in my personal one and correct all my students' work in Google Apps.
