Popular science teaching aid for demonstrating volcanic eruption

Abstract

The invention relates to the technical field of a popular science teaching aid, and in particular relates to a popular science teaching aid for demonstrating the volcanic eruption. According to the technical scheme, the popular science teaching aid consists of a closed hollow conical body which is made of transparent boronizing glass, a glass tube, a pneumatic pressure valve, three electronic switches, a vapor generating device, a plurality of red luminescent tubes, a sound system and a control circuit. The popular science teaching aid is characterized in that a liquid cabin is separated inside the boronizing glass conical body, the top of the conical body is provided with the glass tube, the pneumatic pressure valve is installed in the glass tube, and the pneumatic pressure valve is linked with the luminescent tubes, the vapor generating device and the electronic switches of the sound system. When liquid inside a cabin body is heated to a certain extent in an experiment, the red vapor can be ejected through an orifice of the transparent glass tube, a volcanic eruption sound is also accompanied, the scene of the volcanic eruption can be vividly presented, and the popularization of the volcanic eruption popular science knowledge can be facilitated.

Description

technical field [0001] The invention relates to the technical field of popular science teaching aids, in particular to the technical field of popular science teaching aids for demonstrating volcanic eruption. Background technique [0002] At present, the volcanic eruption teaching tool is generally a volcanic cone, and some can be opened on the cone. The more complicated one is to install some electronically controlled sound and light systems on the basis of the volcanic cone model. These can demonstrate the scenes of volcanic eruptions more vividly, but they cannot let students understand the causes of volcanic eruptions and the internal forms of eruptions. Contents of the invention [0003] The invention provides a technical solution for popular science teaching aids capable of better demonstrating volcanic eruption, which can better demonstrate and explain the phenomenon of volcanic eruption, and helps students understand the cause of volcanic eruption. [0004] The pr...
