A.Design
Physical laboratory is the place to conduct physical science activities and inquiry. It can be divided into two types: demo lab and group lab. The above two kinds of laboratories can be set up or both in accordance with teaching needs and school conditions.

B. Classification
The requirements of the construction of the physical laboratory of ordinary primary and secondary schools are divided into two categories, namely "basic requirements" and "planning recommendations". "Basic" is the school shall meet the minimum requirements, "" planning advice is in reach, on the basis of the" basic "to have higher laboratory equipment capacity of district and school demands.
Based on the actual situation, the school can create a laboratory which is more conducive to training students’ innovative spirit and practical ability, and meet the requirements of education curriculum reform for experimental teaching.

C.Function and requirements
(1) it can meet the requirements of experimental teaching, make it convenient for students to familiarize themselves with and contact some experimental instruments and equipment, and learn to master basic experimental skills.
(2) efforts should be made to facilitate students to consult relevant information, facilitate students to develop experimental plans and design experiment plans, and to create conditions for exploratory learning and subject experiment activities.

D.Planning and design
The "area and number" of physics laboratory, building requirements, environmental requirements, etc., are planned and designed according to the requirements of the science laboratory equipment specification (JY/T 0385 -- 2006).

E.Working conditions
(1) power supply: three-phase four-wire, power supply voltage 220 x (1 + + 10%) V, power frequency 50Hz
(2) water source: 2 x 105Pa
(3) temperature: 0 ℃ and 40 ℃
(4) relative humidity: no greater than 90%
(5) continuous working time: no less than 8h

F.Fixed facilities

(1) basic requirements

a) writing board: the vertical distance between the bottom edge of the writing board and the platform shall be l000mm ~ llOOmm;
b) stage: the horizontal distance between the two ends and the vertical edge of the writing plate should not be less than 200mm, the width should not be less than 650mm, and the height should be 200mm.
c) power supply: the laboratory electrical circuit shall adopt the method of dark application of fire prevention requirements, install automatic power failure protector, and should have reliable grounding measures;
d) water source: all the rooms should be equipped with water supply and drainage facilities, and should be equipped with sinks and mops.

(2) planning advice

a) air source: the gas source can be set according to the need, and there should be some safety measures;
b) communication: one or more network interfaces can be established according to the actual situation;
c) teaching TV: when setting up the TV in the laboratory, it should meet the relevant requirements of GB 8772. Watch distance from the front edge of the seat to the TV screen and the horizontal distance of the TV screen will be 4 ~ ll times the size of the TV screen. Watch the horizontal squint Angle should not be more than 45 °, elevation Angle should not exceed 30 °.
d) teaching screen: when the screen is installed in the laboratory, it should not be lower than 1lOOmm on the lower edge of the screen, and the width of the screen should be 1/6 of the distance of the screen to the last row of seats.
