Here is a site with lots of excellent material that can be used for learning about and teaching Scratch
“These pages provide resources for parents, teachers, and computer club facilitators to structure the learning experience for children as young as seven years old to begin programming in Scratch. We have used videos as a direct method of communication for learning scratch and you are free to download and install this site on your local server if you do not have internet access in the classroom.”
Thanks to Stamati Crook of Redware Research Limited for putting together this resource.

A way to use the #8528 Converter cables to run three motors off of one port! Of course, the motors have to run at the same time, but still.
NXTLOG Robotic Arm Challenge
NXTLOG challenge of the new decade is to design a LEGO MINDSTORMS NXT robotic arm. This can be: The bionic arm of tomorrow A robotic arm designed with many of degrees of freedom An industrial robotic arm A just for fun robotic arm Your robotic arm can be autonomous (run on its own) or run by a remote control.
A nice explanation on how to do rotations with Lego Mindstorms robots and NXT-G.
NXT2excel runs on the pc. It initiates a BlueTooth connection with a NXT and writes data it receives from the NXT to an excel spreadsheet. This allows the user to examine or process the data. Users can automate the processing of the data with the use of a previously built worksheet. This makes it possible to have treal time graphs.
A description of a robotics lesson from a teacher in San Jose California. It is interesting because the students themselves have to create their own challenge!
A collection of tips for using Lego Mindstorms NXT-G for programming your robots.
