By means of the multifunctional chemical test bed used by the student, use of the student is effectively facilitated, and the environment is effectively protected.

Description

technical field [0001] The invention relates to a teaching device, in particular to a multifunctional chemical test bench for students. Background technique [0002] Chemistry is a kind of natural science, which studies the composition, properties, structure and changes of substances at the molecular and atomic levels; it is the science of creating new substances. The world is composed of matter, and chemistry is one of the main methods and means used by human beings to understand and transform the material world. It is a subject with a long history and full of vitality, and its achievements are an important symbol of social civilization. There are two forms of chemical change and physical change in chemistry. [0003] Teaching is a human-specific talent cultivation activity composed of teachers' teaching and students' learning. Through such activities, teachers guide students to learn and master cultural and scientific knowledge and skills purposefully, in a planned and o...

AI Technical Summary

Problems solved by technology

[0004] In the teaching process, in order to show the chemical reaction of the equipment to the students more intuitively, the teacher often needs to let the students learn intuitively through the reaction of the chemical experiment on the chemical experiment table, which can effectively increase the learning of the students, but the current chemical The general structure of the experimental bench is simple, the function is single, and it is generally impossible to adjust the height, which is very inconvenient for students of different heights, and some chemical products produced by the equipment are poisonous, and the solution will pollute the environment. If it is disposed of in time, may pollute the environment
