Laboratory use specification
1. In order to protect experimental instruments and maintain environmental sanitation, students must take off their shoes and enter the laboratory.
2. The laboratory is the place where all teachers and students carry out experimental teaching and scientific research activities. Students should keep quiet and observe discipline after entering the laboratory.
3. Before doing the experiment, listen carefully to the teacher to explain the purpose, steps, performance operation, methods and precautions of the instrument, carefully check whether the required instruments and equipment are in good condition, and report to the teacher in time if there are any defects.
4, the experiment should abide by the operating rules, carefully according to the experimental steps.
5. Pay attention to safety during the experiment to prevent accidents.
6. Take good care of laboratory instruments and equipment.
7. After the experiment, carefully clean the equipment and turn off the water supply.
The physical experimental instrument room mainly stores physical experimental instruments and manages them in categories. The physical experiment preparation room is equipped with an experimental platform and various experimental instruments. The student grouping laboratory is mainly equipped with a student experimental platform with power supply, water supply and gas supply. Indoor lighting, dust prevention, ventilation and sufficient activity space are needed.
