Description

technical field [0001] The invention relates to a teaching experiment device, in particular to a simple sound distance measuring teaching experiment circuit. Background technique [0002] Experimental teaching method refers to the teaching that students use certain equipment and materials under the guidance of the teacher to cause some changes in the experimental objects through the operation process of controlling conditions, and obtain new knowledge or verify knowledge from observing the changes of these phenomena. method. In the teaching of subjects such as physics, chemistry, biology, geography and natural knowledge, experiments are an important method. General experiments are carried out in laboratories, biological or agricultural experiment gardens. Some experiments can also be done in the classroom. Experimental methods emerged with the development of modern natural science. The rapid development of modern science and technology and experimental methods has made e...
