Using a Google Cardboard viewer, a mobile device, and the Expeditions app, I got to go on a field trip with the students who were part of the class. Here are some photos of the cardboard viewer with the mobile device placed in it:
When I visited the moon, I had free reign to look at what I wanted to see (360 degree view). When the teacher wanted me to look at something in particular, an arrow would appear on my screen to tell me what direction to move to in order to see what the teacher would be talking about. The teacher's tablet (the brains of the operation) acts as a lesson plan of sorts and it is connected to all the viewers.
Aside from enjoying the virtual reality experience of going somewhere I had never been before, it was a lot of fun watching the students as they held the viewer to their face and moved around in circles looking up and down.

Here is some footage (not that good but I did my best!) that I got with my smart phone of what you view when you move around:
