We started by going over my expectations. All the students related that they liked each other so I would not have any problem.
Next I cautioned the students that when they first start working on the actual coding it will be hard! They may not get it right their first time out of the gate. We watched a video I found on YouTube called Famous Failures.
I then unpacked one of the makey makey boxes and showed them the contents and how to put them together. We discussed circuits, conductors, and insulators. I didn't need to go into much detail; their classroom teachers had done a good job with this SOL.
After showing them how to access the website with the activities:
Two of the students created a computer keyboard using only themselves. In other words, they put the alligator clips on themselves and tried to see how fast they could type just by moving snapping their fingers. Two other students connected the clips to their chairs and created a Tetris game with their chairs being the game controller. (Although I started off with five, I lost one student who left early because she was sick.) I just walked around amazed at their creativity and did nothing more than snap pictures.
To end the time the students wanted to teach me something. It was really cool so I want to share the following with you.
