Hi all,
Promised in teh beginning to post some ideas and also keep you all posted on how i do this in the classroom...
Well, here goes...
Last week was my first lessen, i didn't completely devote all the hours for that week to it but just to let them knwo what we were going todo.
- showed them the inventors kit
- told them they would have to look for an interesting goal (like a small robot)
- told them they had to maintain a blog with all the links, ideas, pictures, video's and progress they would make
- showed them the first pages of the manual we use with some of the basic stuff in it...
their curiosity was visible 
Today i explained some basics of electricity (current (I), resistance (Ohm), power (P expressed in Watt) and so on...
I made some exercices with the formulas and then i gave them their kits.
- showed them the manual and how to assemble
- connect to the computer
- upload first sketch with blinking led
Everytime I'm going to give them an hour of theoretics and some small exercices and then they can use that info for some new things to use for their robot...
This seems to work for me, and them...
I'm having fun!
Regards,
