Abstract

The invention discloses a buoyancy experiment device used for physics teaching. The device comprises a fixed device, lifting devices and an experiment adjusting device. The lifting devices are arranged on both sides of the top of the fixed device. The fixed device comprises a base. A first fixed seat is arranged in the middle of the top of the base. An experiment beaker is arranged in the first fixed seat. A second fixed seat fixed on the top of the base is arranged on the right side of the first fixed seat. A water receiving cup is arranged in the second fixed seat. The top of the right end of the experiment beaker is communicated with the water receiving cup through a connecting tube. Fixed blocks are arranged on the left and right sides of the base. Each lifting device comprises a sleeve. The sleeves are fixed on the top of the fixed blocks. A gear is arranged in the middle in each sleeve. According to the invention, the device can prevent a spring dynamometer from shaking during anexperiment, so that measured experiment data are more precise; the device has the advantages of simple operation and convenient use, and is convenient for the classroom teaching of a teacher; and theteaching effect is better.

Description

technical field [0001] The invention relates to the technical field of teaching appliances, in particular to a buoyancy experiment device for physics teaching. Background technique [0002] The law of buoyancy of an object, also known as Archimedes' law, according to Archimedes' principle, an object immersed in a liquid is subject to an upward buoyant force, and the magnitude of the buoyant force is equal to the gravity of the object displacing the liquid. It is a physics very important law. Therefore, the buoyancy experiment is a basic experiment that middle school students should understand and master. However, in the actual theoretical teaching, this law is relatively abstract and difficult to understand. In order to deepen the understanding, teachers often make various teaching aids to calculate the weight of the liquid discharged by the object. The teaching aids generally include weights, beakers, water Containers and spring dynamometers, etc. However, in the actual ...
