Description of the Experience
The lesson was learned easily because I personally saw it with my eyes.
After the experiment I already had more natural explanation for what is happening in it.
The expected effect of the experiment was to see the mixing of the three primary colors of the spectrum of light (green, red and blue).
Our experimental unit consisted of a top, which upper part was divided in three equal parts, corresponding to the three primary colors of the visible spectrum of light. While spinning it was observed white color of the light. My achievement lies in the fact that experimentally I proved that in order to get white light we could use just green, red and blue colors. The difficult part of the experiment consisted in attempts to spin the spinning top with sufficient angular velocity in order to observe only white color.

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.
