The invention provides a physics teaching desk with a safe storage function. The safety issues of inconvenience of physical experiment teaching and missing and damage of experimental instruments and the like in the prior art are effectively solved. The teaching desk comprises a teaching desk body, the lower portion of the teaching desk body is buried under the ground, a storage box is connected with the interior of the teaching desk in a sliding mode, the upper surface of the storage box is parallel to the ground when the storage box is placed peacefully, a drawer is arranged above the interior of the teaching desk, a first empty cavity is formed between the drawer and the storage box, and the upper surface of the teaching desk is rotatably connected with a chalk box. The teaching desk has the advantages that the structure is simple, use is convenient, the functions of a locker are integrated to the teaching desk, an unexpected effect is achieved, the storage box is located under the ground, so that space is saved, the storage box is hard to find, and the probability of instrument going missing is significantly reduced; too many experimental instruments are no longer needed by a teacher during the teaching, the teaching can be conducted directly, and the teaching efficiency is improved.
