I have a new website on the horizon-- Project MAKE. It's the first of many sites you will see debut this summer. The url is http://teachingvision.net/projectmake.
It is a virtual makerspace website for ages 10+ and a compilation of numerous resources I located from all over the Internet. Nothing is credited as my own as of yet-- it's basically a phenomenal collection of links-- but some resources may surface in the next few months.
Thanks, and enjoy Project MAKE!
