A teaching device for physics experiments

Abstract

The invention provides physical experiment teaching equipment comprising an experiment table, an image photographing frame and a trigger controller. The experiment table includes a wooden plug, a testtube and an alcohol lamp. The image photographing frame comprises a frame body and image photographing equipment. The frame body is provided with a trigger mechanism. The test tube is internally provided with a temperature sensor which is connected with the input end of the trigger controller. The trigger mechanism is connected with the output end of the trigger controller. The coming result of the experiment can be prompted in time by the temperature sensor, and the jet moment can be recorded through cooperation of the high speed camera so as to enhance understanding of the students for thewhole experiment process.

[0002] Physics experiment teaching is a very important teaching method. This teaching method can quickly and intuitively allow students to grasp the physical phenomena corresponding to the physical theory, and improve students' concrete understanding of physical theory. Compressed air in the existing physical experiment class The experiment of cork opening has a certain degree of danger. More and more schools use only teachers to conduct demonstration experiments, so that students can have an intuitive impression of this type of experiment. Because the existing teaching courses cannot use small classes on a large scale teaching, so it is very difficult for everyone in a class of more than 30 people to see the whole process intuitively at the same time. At the same time, because the experiment needs to boil cold water and wait for the air to expand to push the cork off, the experiment process is relatively difficult. It is long, but the result happens in an instant, which makes the process very boring if the teacher waits for the whole experiment to be completed. If the teacher puts it aside to give a lecture, it is easy to miss the moment when the cork is ejected, resulting in a greatly reduced demonstration effect.
