Abstract

The present invention is a kind of buoyancy demonstration teaching aid, is characterized in, it is made of container, conduit, aspirator and demonstration piece, and described container is a closed container, and the demonstration water is housed in the container; Described conduit two ends are connected on container and the aspirator, and the demonstration piece places container.The present invention is a kind of teaching aid that is specifically designed to demonstration buoyancy.During use, advance or extract aspirator out, atmospheric pressure in the container is increased or reduce, thereby make buoyancy become big or diminish, thereby make demonstration piece come-up or sink, to very lively directly perceived of the demonstration of buoyancy with hand push.

Description

Buoyancy demonstration teaching aid
Technical field
The present invention relates to a kind of teaching aid, particularly a kind of buoyancy demonstration teaching aid.
Background technology
In the prior art, in physics teaching, be not specifically designed to the teaching aid of demonstration buoyancy, thereby make the buoyancy teaching lively inadequately directly perceived.
Summary of the invention
Technical matters to be solved by this invention is at the deficiencies in the prior art, and a kind of simple in structure, lively buoyancy demonstration teaching aid intuitively is provided.
Technical matters to be solved by this invention is to realize by following technical scheme.The present invention is a kind of buoyancy demonstration teaching aid, is characterized in, it is made of container, conduit, aspirator and demonstration piece, and described container is a closed container, and the demonstration water is housed in the container; Described conduit two ends are connected on container and the aspirator, and the demonstration piece places container.
Compared with prior art, the present invention is a kind of teaching aid that is specifically designed to demonstration buoyancy.During use, advance or extract aspirator out, atmospheric pressure in the container is increased or reduce, thereby make buoyancy become big or diminish, thereby make demonstration piece come-up or sink, to very lively directly perceived of the demonstration of buoyancy with hand push.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
