Description of the Experience
The experiment I’ll always remember is the one with the ozone test papers; we made these ozone out of coffee filters and applied some paste on them. I can’t remember very well but I think we used cornstarch and distilled water for the paste. We also added less than a teaspoonful of PI. The most exciting thing was when we left the strips of the test papers in several spots inside our school and outside our school (near a very busy road). The papers displayed different shades of purple. The ozone in the air reacted with PI and water and produced O2, iodine and potassium hydroxide. Iodine reacted with the cornstarch and turned purple. The intensity of the color depended on the amount of ozone in the air. A purple color indicates more ozone, and a yellow color indicates less ozone. Chemistry is really interesting.

Dissemination Seminar in Florence

31 October 2015 The seminar has been held in ITIS “A. Meucci” one of the schools involved within Goerudio project activities. Its main aim was to promote the results of the project toward a broad sample of stakeholders even overcrossing the number of people directly involved in the production of project outcomes. This purpose has been totally achieved especially thanks to the participation of students and teachers coming from different schools or from other classes instead of those ones directly involved within the project activities.
