BigGreenHelp (http://www.biggreenhelp.com)

The site's high-production look is sure to appeal to kids and it imparts good messages and offers some educational information, but one would think that, given Nickelodeon's vast resources, there would be a little more substance. The daily tips, message board, and video upload are the strongest features -- hopefully kids will take advantage of the last two to communicate ideas to keep the Earth healthy. The glossary is good but has a typo or two. Correct answers are not provided for the quiz (which also has some typos) and you never know how many answers you got right. Perhaps this is to keep kids returning to try to improve their rating, but some kids might get frustrated. The Sponge Bob game, which has no educational value, could use more instructions as it took a few tries to figure out that clicking the right mouse button activated the vacuum.

The upcoming multiplayer game sounds promising, and as the video diary and message board continues to grow, BigGreenHelp.com could evolve into an busy online community where kids exchange ideas and share their green efforts.
