Mark started the list a week ago but has already found interested teachers from around North America who have contributed documents, like a PowerPoint slideshow on biodiesel designed for 4th graders. Right now, Mark is looking for a co-moderator, preferably someone who works with kids with an interest in biofuels, to help run the site. You can check out the group here.
UPDATE: Girl Mark said she's not really responsible for "starting" the group. It just sort of grew out of an idea the New Jersey science teacher Dan Smith.
