One of the issues that I have with the World Wide Telescope tools is that they take a little practice to use, but once you get good at it, then this tool gives your students motivation to use the computer beyond just texting, tweeting or using facebook (facebooking?).
In the classroom, this tool is a great way to examine the world without the cost of a field trip and important thing these days.
Zoom over to: http://www.layerscape.org/Home/Index if you have World Wide Telescope installed.
If you don’t have World Wide Telescope installed go to: http://www.layerscape.org/Home/InstallWWT
If you are student or teacher, this is a great way to learn more about the world around us.
