When I taught fifth and sixth grade, I subscribed to IndyKids, a really great resource created by kids for kids. Recently I stumbled upon Youngzine, another youth resource for youths.

There are a host of other sites that dig into these deeper causal issues. One such site is Better World Flux which allows one to see how various indicators have changed over time and geography.
