To develop computational thinking unplugged, following the steps to do a recipe is a good start. In this case, one student did the recipe to cook "conductive dough" to be used in other projects. You can follow the instructions of the picture and view the video (in spanish), and later do the buttons explained at Buttons .

Because unplugged activities give an efficient learning curve at the beggining, lets icebreak with them... This is an example of the explanationa of 7 OSI layers with the communication process of a printing machine, performed by students.
