The interest in studying quantum mechanics is increasing in our society and topics related to quantum physics are now part of high schools' programs. This leads researchers to implement suitable actions to meet social needs of knowledge of quantum physics. A possibility can be to focus on one of the main conceptual issues of quantum mechanics, that is the wave-particle duality and develop suitable learning strategies to highlight the manifestation of the dual nature of matter and light. We present an inquiry-based-like laboratory on wave-particle duality for high school students (17-19 years old) implemented with the RIALE online platform, developed by CRS4. The activity has been done in the period December 2021 - May 2022 at the Physics Department of the University of Cagliari and more than 100 hundred students from different high schools in Sardinia have been involved. We will show the design of the activity and the experiments performed. We will give some details about the platform we used during the online laboratory and its potential use as an online educational tool in high schools. A brief discussion about the assessments and motivational issues will be done.
