When projecting your screen to your students, you may not want to share your most frequent webpages and reveal your addiction for shopping on Amazon.com or your hobby of bird watching.
There are two great Chrome extensions that allow you to view random Google Earth or Google Art Project images when you open a new tab, instead of seeing your top webpages. Below is a view of Amposta, Spain. Each time I open a new tab, I get a different image and can imagine I'm traveling the world.
To install these extensions, click on the corresponding link below. (You can only install one of these two extensions.) You will need to accept the terms of using the extension. Then, when you open a new tab, you'll see beautiful Earth images or artwork.
