On Monday, December 11, 2023, Mrs. Nary Eang led the 10C-grade students of American Intercon School, Tuol Kork Campus to carry out an experiment on "Fresh Water Protist Observation " on the subject "biology." The purpose of this experiment is to provide students with a better understanding of the lessons that can impart real knowledge to students and enhance their memory in theoretical studies. The students, in addition, practiced, collaborated and worked well together as a team.
