On May 20, 2022, the committee of American Intercon School, Mao Tse Tong campus, organized an experiment on classification of mixtures for 8th graders. This experiment was led by a chemistry teacher, Ms. Lim Sotheavy.
In the experiment, the teacher took the main points of the lesson to show to the students which included how to separate the mixture and how to use the materials in the experiment. The teacher then explained the detail of the experiment and clarified the uses of materials. Then, the teacher explained how to do the experiment step by step clearly. At the same time, the teacher divides the students into groups to practice conducting the experiments directly to examine the form of separation in connection with the theory of the lesson.
