Abstract

The invention provides a simple multifunctional water lens and belongs to the technical field of teaching aids. The simple multifunctional water lens comprises a barrel, a liquid conveying pipe, a needle tube, two latex films and rubber bands; the latex films are fixed at the end part of the barrel through the rubber bands; one end of the liquid conveying pipe is fixed on the barrel and is communicated with the barrel; and the other end of the liquid conveying pipe is connected to the needle tube. According to the design of the simple multifunctional water lens, the multifunctional simple water lens is self-made by using common articles in life, the cognitive development level of students can be presented more vividly and intuitively; the learning interestingness of the class can be increased; and the observation ability and scientific thinking of the students are effectively cultivated. In physics teaching of junior high schools, an experiment is easy to operate and high in visibility, the interest of students in manual exploration is stimulated, and the scientific exploration ability of the students is promoted to be improved.

Description

technical field [0001] The invention relates to the technical field of teaching appliances, in particular to a simple multifunctional water lens. Background technique [0002] The water lens is an instrument commonly used in junior high school physics teaching. It is often used to simulate the adjustment process of human eyes. Although the water lens has an important use in teaching, due to the complicated production method of the existing water lens, PVC pipes or other materials are often used as the main body of the load. Because these equipment are not easy to find in life, and the production requires a certain technical basis, it is not convenient Front-line teachers quickly make and apply it to teaching. Contents of the invention [0003] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a simple multifunctional water lens, which can be made by using common daily items to make a multifunctional simple water lens...
