Description

technical field [0001] The invention relates to the technical field of chemistry teaching models, in particular to a teaching model that is convenient for observing changes in chemical experiments. Background technique [0002] Chemistry is an important course, and chemical experiments play an important role in chemistry teaching. Chemical experiments require us to carefully observe the experimental phenomena and changes in the experiment, such as temperature and pH value, from which we can summarize and draw conclusions. However, there are many safety hazards in the experiment process, and the experimental phenomena are not easy to observe intuitively and clearly, and the data changed in the experiment cannot be obtained in time. Contents of the invention [0003] The purpose of the present invention is to provide a teaching model that is convenient for observing changes in chemical experiments, so as to solve the problems raised in the above-mentioned background technol...
