Abstract

The invention relates to the technical field of science-popularizing teaching tools, in particular to a science-popularizing teaching tool for demonstrating a siphoning phenomenon. The science-popularizing teaching tool for demonstrating the siphoning phenomenon is mainly composed of a plastic rockery base, a plastic water tank, water pipes, a water tank support and the like. The science-popularizing teaching tool for demonstrating the siphoning phenomenon is characterized in that a water groove is formed in one side of the rockery base, a platform is arranged at the portion, close to the top, of the other side of the rockery base, the water tank support is installed on the platform, the water tank is installed on the support, the upper portion of the water tank is square, the lower portion of the water tank is triangular, a water injection nozzle is formed in the top of the water tank, a water inlet pipe is arranged at the portion, close to the top, of one side of the water tank, a water outlet pipe is arranged at the lower portion of the water tank, a valve is arranged on the water outlet pipe, the lower end of one water pipe is arranged in the water groove of one side of the rockery base, the other end of the water pipe is connected on the water pipe, close to the top, of the one side of the water tank, one end of the other water pipe is connected on the water outlet pipe arranged at the lower portion of the water tank, and the other end of the water pipe is arranged at the bottom end of the side, corresponding to the water groove, of the rockery base. According to the science-popularizing teaching tool for demonstrating the siphoning phenomenon, the siphoning phenomenon can be demonstrated and explained in a visualized mode.

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 the siphon phenomenon. Background technique [0002] At present, the teaching aids for demonstrating the siphon phenomenon are generally two containers, one containing water is placed at a higher position and the other container is placed at a lower position, and then a hard tube is used as a siphon to suck water from the higher container to the lower in the container. Although this experiment can enable learners to understand the principle of siphon phenomenon to a certain extent, it is not intuitive enough, especially not interesting enough to cause learners to have cognitive conflicts, and it is inconvenient to operate. Contents of the invention [0003] The invention provides a technical scheme of popular science teaching aids for demonstrating the siphon phenomenon, which can bett...
