For the second year, the Faculty of Science at Beirut Arab University has participated in the “Science Days- Ayam Al Ouloum” that was held on the 24^th of October till the 26^th. Postgraduate students from both Department of Biological and Environmental Sciences and Chemistry carried out 5 different Projects in two separate tents. Their Participation was highly successful in reflecting departments’ standards in education. This was achieved by proper choice of projects to be demonstrated and efforts of the postgraduate students. Visitors from different ages, institutions and backgrounds showed great interest in our projects and our two tents were among the tents with the highest contribution to the goals of “Science Days” in spreading scientific knowledge and broadening their horizons of students in choosing their future specializations.
