On 23rd of December 2019, Physics Education Department at Tishk International University, organized a poster presentation on Modern Physics. The 3rd grade students presented valuable posters in which they covered the  most recent topics in Modern Physics. Modern physics based on the two major breakthroughs of the early the twentieth century: relativity and quantum mechanics. The presented topics were discussed and evaluated by professors from the physics department. Thus, the Physics Department believes that the activities offered a good chance for the students to try and improve their teaching skills in explaining. Finally, we would like to thank all the students and the staff members that they made this event succeeded.
