On December 27, 2021, teacher Ry Sotheavy led grade 7th students of American Intercon School, Phsar Thmey Campus to conduct Chemistry experiment topic “Density of Solids and Liquids”. Before the experiment, the teacher showed as well as described the experimental materials such as clear calibrated glass baker, calibrated glass, electronic scale, oil, metal and water.
It should also be noted that the objectives of the experiment are to:
• Use scales to weigh unit mass
• Use calibrated glass to measure fluid volume
• Calculate the density of solids and liquids.
• Compare the densities of submerged and floating in water.
