This was a Google Education On Air Hangout broadcast on June 4, 2013.
It presents some simple design techniques that you and your students can use in Google Earth to format your placemarks with images, text, and video using HTML code.
Google Earth Tutorials:
These video tutorials are screen captures that demonstrate a particular skill used in Google Earth or a demonstration of a Real World Math lesson. Some videos may offered as Kmz files to play in Google Earth’s placemark windows, so that instructional references to the application can be seen simultaneously. These are all YouTube videos.
