The Extreme Energy Events Project (EEE) represented since its starting phases in 2005 a breakthrough in outreach activities in High Energy Physics. The innovative idea of EEE is a strong and direct involvement of high school students in the construction and operation of an experiment to measure Extensive Atmospheric Showers (EAS) on Earth surface.
The EEE Project is based on an array of muon telescopes each one consisting of three high performing Multigap Resistive Plate Chambers; EEE chambers were built by students and teachers at CERN, transported and installed inside Italian school buildings, where local teams help to monitor, operate the detectors and contribute to data analysis. About 60 EEE telescopes are presently installed in Italy. Since 2014, coordinated data taking periods have been performed during each year and more than 100 billions of candidate muon tracks have been collected and used for many analysis. Every year about 100 schools participate to the EEE Project, half of which without a telescope but included in the online operations, with hundreds of students and teachers involved in the activities directly correlated to EEE, but also touching different physics topics. The COVID-19 pandemic has strongly affected the experimental activities of the EEE Project, however in the last two years the online activities were strengthened, with an intense program of collaboration meetings, masterclasses and topical seminars that were organized with enormous success.
A general overview of the EEE outreach activities and the future plan will be presented.
