This video demonstrates how to add Placemarks to Google Earth to create tours, also known as “virtual field trips”.
What’s a Placemark?
Placemarks allow you to set a course of “travel” in Google Earth. Instead of navigating blindly, or using the search bar to go from one location to another, placemarks allow you travel with the simple click of a button. Placemarks permit greater student participation, and allow you to add embedded media like pictures, text, and video.
Placemarks are saved in your “My Places” in the left hand sidebar, and can be saved as .KMZ files to be shared with others.
