In the past couple of days I've come across some very informative sites that show and explain some of the circumstances in Japan. The first site listed is particularly helpful in really seeing the large changes that have occurred as a result of this tragedy.
This site, presented by The New York Times, was shared with me by a colleague in my district and it is the first I've seen that provides an interactive comparison of impacted regions. When you open the site you will want to move your mouse to the center of the images, then click and drag to move the slider. The slider serves to move the overlay of current images of the same area.
This second site I learned of from @edtechsandyk through Twitter. The article, presented by The Washington Post does a great job of explaining the importance of the written language and how communication is being delivered amidst this tragedy. In this day of modern communication through technology I think it serves well to remind us adults and students of the importance of written word. Check it out here.
