Abstract

The invention provides a snowfall flow simulation device for primary school science teaching demonstration. The device of the invention comprises a control electric box, a cloud model, a model support, a magnet and a tube. The tank body is rectangular in shape, and a cover plate is rotatably arranged at the middle position of the rear sidewall of the tank body. The cover plate is horizontally corresponding to the front and rear sides of the model support at the lowest height position. The middle position of the right sidewall of the tank body is provided with the control electric box. Two axial flow fans are symmetrically fastened at the top positions of left and right sidewalls of the tank body. The two axial flow fans are electrically connected with a switch button on the control electric box. Two limit switches are supported and installed at intervals on the left internal wall of the tank body. The two limit switches and a positive and negative relay inside the control electric boxare connected in series and charged with electricity, and the highest and lowest suspension heights of the model support are further controlled. With the arrangement of two sieve tanks, the two sievetanks can be removed and alternately used so as to avoid the step of collecting falling plastic snow. The device of the invention is convenient to use.

Description

technical field [0001] The invention belongs to the technical field of teaching equipment, and more specifically relates to a snowfall process device for simulating weather based on elementary school science teaching demonstration. Background technique [0002] The new curriculum standard replaces "nature" in the current syllabus with "science". The content, that is, "to guide students to acquire some simple basic knowledge of natural science, and at the same time cultivate their interest in science, and the ability to learn and use science." After "nature" is changed to "science", the content of the course can be more accurately summarized, which not only allows students to acquire scientific knowledge, but also allows them to learn scientific inquiry methods; it not only cultivates students' interest in science, but also cultivates their scientific natural view . In addition, most of the primary school science courses in the world today are named "Science". We learn from...
