In this video I demonstrate how to add videos to Google Earth projects (tours) in the web-based version of Google Earth.
Applications for Education
While I created the video above specifically with my lesson plan in mind, the concept in the video can be used for any Google Earth project that your students are working on.
Since YouTube has to be used to host the videos you want to include in Google Earth projects, I'm recommending using the "unlisted" option in YouTube for any videos that feature students. In this video I explain how to use the unlisted option in YouTube.
