The ocean covers 70 percent of the Earth's surface. It contains about 324 million cubic miles of water, which is about 97 percent of all the water on Earth. The ocean makes all life on Earth possible! Celebrate World Ocean Day with Explorer Classroom this June!
Register for an Explorer Classroom session by clicking the “Register Now” button. You’ll find the link to the live stream on the registration form.
The first six classrooms to register will be awarded on-camera spots.* Those classrooms will have the opportunity to interact with the featured Explorer directly—just like in a Skype call. If you are one of the chosen classrooms , you’ll hear from your host Joe Grabowski or a Nat Geo staff member by email at least one week before the event.
If you do not secure an on-camera spot, no worries! An unlimited number of people can watch live, and anyone can ask questions by tweeting #ExplorerClassroom.
Tune in at the scheduled time and date! The live stream link is on the form you used to register.
If you can’t join live, you can catch up later. All Explorer Classroom sessions will be archived on YouTube.
*Please Note: Explorer Classroom sessions are live events hosted on YouTube. They are open to the public and recorded. Please share these terms with parents of students who will participate live on camera. If any parents or students prefer not to be on camera, please accommodate their wishes in your classroom.
All Explorer Classroom hangouts are recorded so you can review them a second time or save them for just the right moment in the semester. Browse our archive to start exploring now!
