For the last two summers our Middle School students participated in a Summer technology elective. This year we opened the program up to some of our elementary school students and in invested in the Lego Mindstorm robotics and WeDo kits.
Of coursed I was elated to be getting robotics added to our program, but much to my surprise it was the Lego WeDo kits ended up peaking my interest. While doing my research, I found some that these kits could be powered by the MIT Scratch program with a simple change to a PC. This got even more interesting was that I remembered that one of our teachers had a stack of Lego Simple Machine kits in her closet.
The Lego WeDo kits are motors, switches, lights and a distance sensor driven by a USB hub and computer software. What makes this interesting is it provides a bridge from software and the physical world. Students create machines with wheels, gears and pulleys and control them with a computer keyboard.
