When I first show people Google Earth, I do the classic zooming down to find someone’s house. Or turn on a layer like Banks/ATMs to show how the data can be useful.
But, the real shocker about Google Earth is when you show them the “Tilt” feature and that this is a 3D model of the world! Any mountainous area will do, but let’s try Mount St. Helens 
which is a particular good view. After going there, find the up/down slider on the right side of the navigation area of Google Earth (when you put your mouse over it will say “Adjust Tilt”) and try it out.
IMPORTANT TIP: the best way to take control of your 3D viewing of Google Earth is to use the middle mouse button. Click and hold the middle button and watch how you can pan and tilt around any view. Another tip is to hold down the SHIFT key while doing this and making circular motions to pan at a fixed tilt.
