We, secondary school students, have created a workshop to teach our younger mates at primary school what a smart city is. We read the tale of Ona, a giraffe who lives in a smart city called Barcelona, and then, in small groups, we explained how to make a smart crosswalk that only stops traffic when a person is awaiting to cross. For this we simulate the traffic lights with a computer program coded in Scratch language. Students made the crosswalk using cardboard, aluminum foil and scissors. The crosswalk actuates as a sensor based on electricity conductivity and the interphase with the computer is made by a MakeyMakey card.
Similar to the traffic lights case we explained an automatic watering system with a simple sensor that detects the humidity level of the soil.
Finally little students made drawings of smarts solutions for the city. We enjoyed a lot!
