Students must follow all the written and verbal instructions when conducting the science experiment. In case they do not follow anything, they must clarify it first.
It is very important to be alert and be cautious when in the science laboratory. Eating, drinking, playing pranks, using mobile phones, or listening to music should be strictly prohibited.
Before using any chemicals, read the label carefully. When mixing chemicals or conducting the experiment, keep the test tube containing the chemical away from your face, mouth, and body.
Unused chemicals should never be put back in the original bottle. They must be disposed off as per the guidelines given by the lab assistant or science teacher.
Students must be made to wear safety goggles, lab coat, and shoes in the science laboratory. Loose clothes, sandals, and open hairs should be a strict NO in school science labs.
