Previously, Google Expeditions allowed teachers to guide their students through a tour as they viewed it on phones enclosed in Google's Cardboard viewers. Now, with Self-Guided Expeditions, teachers can assign tours as homework and anyone else can easily explore on their own. In Explorer mode, points of interest will be highlighted and relevant information will be provided on the screen. Additionally, teachers will now be able to annotate screens as they guide their students through a tour.

Google Expeditions has over 600 different tours including the Seven Modern Wonders of the World, the Great Barrier Reef and even sites like baseball stadiums and solar power plants. For now, the app is only available for Android, but Google says an iOS version is in the works.
