Second LIfe

I was asking my junior high and high school students today if any of them use this web site. Many did not even know what it is. Some kind of heard about it or know someone that uses it. Some of them referred to Second Life being like SIMS. A few of my students do use it. One girl is a 7th grader, her friend gave her a password so she can use the site. I I wonder if parents know what there kids are doing.
