Primary school science buoyancy measurement experiment device

Abstract

A primary school science buoyancy measurement experiment device disclosed by the present invention comprises a support, the left end of the top of the support is provided with an air cylinder, the inner cavity of the air cylinder is connected with a bracket through a piston, the bottom of the right side of the air cylinder is communicated with an air bag through a pipeline, and the top of the air bag is provided with a buoyancy block. A demonstration box is arranged at the right end of the top of the support, and a first supporting plate is arranged on the top of the support and located on the right side of the demonstration box. The air cylinder, the piston, the support and the air bag are arranged, air in the air cylinder can be conveyed into the air bag through a pipeline, the air bag can adjust the buoyancy of the buoyancy block in water, the requirement for buoyancy and air volume measurement experiments of people is met, meanwhile, people can pour liquid with different concentrations into the demonstration box or put solid with a small volume into water, and the demonstration box is convenient to use. Therefore, the purpose of experimenting the buoyancy of the buoyancy block in liquids with different concentrations by people is achieved, and great convenience is brought to the use of people.

Description

technical field [0001] The invention relates to the technical field of teaching appliances, in particular to a primary school scientific buoyancy measurement experimental device. Background technique [0002] Education is a kind of teaching of thinking, and people have different thinking trends because of their own ideology. Therefore, education should teach people with the most objective and fair ideological thinking. In this way, people's thinking will not be Being too deviant, gradually becoming mature and rational due to rich thinking, and thus leading to the most rational self and having the most correct thinking and cognition, this is the root of education. At the same time, education is also a process of teaching and educating people. It is a practical activity to improve people's comprehensive quality by teaching others the most objective understanding, and then gaining the values ​​they think in their own life experience.

[0002] Education is a kind of teaching of thinking, and people have different thinking trends because of their own ideology. Therefore, education should teach people with the most objective and fair ideological thinking. In this way, people's thinking will not be Being too deviant, gradually becoming mature and rational due to rich thinking, and thus leading to the most rational self and having the most correct thinking and cognition, this is the root of education. At the same time, education is also a process of teaching and educating people. It is a practical activity to improve people's comprehensive quality by teaching others the most objective understanding, and then gaining the values ​​they think in their own life experience. Education is to cultivate talents for the future. Primary school is when people accept elementary Formal education schools are an important part of basic education, and they belong to the nine-year compulsory education. During the teaching process of primary schools, buoyancy demonstrations are required. Buoyancy means that objects are in fluids, including liquids and gases. The difference between the pressure of liquid and gas, in order to improve the understanding of buoyancy for primary school students, buoyancy experiment device needs to be used, but the existing buoyancy experiment device has a simple overall structure and single function, which cannot meet the growing needs of people. Therefore, we propose a An experimental device for measuring buoyancy in primary school science
