Abstract

The invention provides a chemical experiment demonstration platform. A camera and a collection integrator are fixed to a bottom plate. The camera and the collection integrator are fixed to the position opposite to a test tube. The chemical experiment demonstration platform has the advantages that through demonstration of the platform, the camera and a collector are connected to a computer, so that students can see the experiment frames clearly and completely; the experiment process and critical processes can be represented, and the cognitive level of the learned knowledge is improved; double-color background paper of half black and half white is pasted to a background board on the demonstration platform, forward arrangement or reverse arrangement can be selected according to the color of the tested matter, and the test tube is fixed to the background board to emphasize the experiment effect; a physiochemical board is adopted for a base of the experiment platform, and acid-base resistance and corrosion prevention can be achieved.

Description

technical field [0001] The invention relates to a teaching instrument, in particular to a chemical experiment demonstration platform. Background technique [0002] Most of the traditional chemical experiments are performed by the teacher. Due to the long observation distance, the influence of the experimental phenomena by the environmental conditions, the instantaneous occurrence or disappearance of the experimental phenomena, and the inconspicuous experimental phenomena, the observers often cannot observe the experimental process clearly, comprehensively and accurately. , Experimental phenomena, thus losing the effect of the experiment. Contents of the invention [0003] The purpose of the present invention is to provide a chemical experiment demonstration platform with simple structure, convenient use and simple and clear experimental phenomena. [0004] The present invention is realized through the following technical solutions: [0005] A chemical experiment demonstr...
