On Thursday, March 17, 2022, Mrs. Savong Phal led the 12th grade students of American Intercon School, Tuol Kork Campus to carry out an experiment on “Acid-base Rate” on the subject “chemistry.” The purpose of this experiment is to provide students with a better understanding of the lessons that can provide the students with real knowledge and enhance their memory in a theoretical study. In addition, the students practiced, collaborated and worked well together as a team.
