The utility model discloses a kind of buoyancy generating cause teaching demonstration instrument, belong to tutor auxiliary platform apparatus field, comprise base and support, the centre position of support arranges two iron rings, iron ring is provided with the first transparent collecting bottle and the second collecting bottle, first collecting bottle and the equal upper and lower opening of the second collecting bottle, the lower aperture place of the first collecting bottle is provided with bottle cap, a table tennis is all shelved with in first collecting bottle and the second collecting bottle, also comprise three-way pipe, wherein two arms of three-way pipe stretch into the first collecting bottle and the second collecting bottle, another arm connects a funnel, described funnel is supported on above the first collecting bottle and the second collecting bottle by the 3rd iron ring, adopt this demonstration instrument, student's understanding is got up easily, understand more deep and thorough, successful, student convinces more, knowledge is allowed more to simplify, teacher lectures expression also more easily, and this demonstration instrument makes simple, and cost is low, the iron stand in laboratory, funnel and expense plastic bottle etc. can be adopted to make, and cost is low.
Description
Technical field
The utility model relates to a kind of tutor auxiliary platform apparatus, particularly relates to a kind of buoyancy generating cause teaching demonstration instrument.
Background technology
Buoyancy is an important knowledge in Physics Classroom, and in the past in the teaching process of buoyancy generating cause, allow student know buoyancy Producing reason mainly through inference method, object is subject to the effect of the two-way pressure difference of fluid.Student understands " reason " but directly perceived, and understands more difficult, teacher's instruction is also beyond expression of words, seems and is pale and weak.
Summary of the invention
The purpose of this utility model is just to provide a kind of buoyancy generating cause teaching demonstration instrument, to solve the problem.
To achieve these goals, the technical solution adopted in the utility model is such:
A kind of buoyancy generating cause teaching demonstration instrument, the support comprising base and be connected with described base, the centre position of described support arranges two iron rings, be respectively the first iron ring and the second iron ring, described first iron ring and the second iron ring line centered by support are symmetrical arranged, described first iron ring and the second iron ring are respectively arranged with the first transparent collecting bottle and the second collecting bottle, described first collecting bottle and the equal upper and lower opening of the second collecting bottle, and opening is above greater than opening below, the lower aperture place of described first collecting bottle is provided with the bottle cap corresponding with opening, a table tennis is all shelved with in described first collecting bottle and the second collecting bottle, also comprise three-way pipe, described three-way pipe is Y-shaped, wherein two arms of described three-way pipe stretch into the first collecting bottle and the second collecting bottle, another arm connects a funnel, described funnel is supported on above the first collecting bottle and the second collecting bottle by the 3rd iron ring.
As preferred technical scheme: be provided with beaker below described second collecting bottle.
First collecting bottle and the second collecting bottle all can use the mineral water bottle finishing off water it to be cut off by the waist, use its upper half, during use, to funnel pouring liquid, liquid flows into the first collecting bottle and the second collecting bottle by three-way pipe, because the lower aperture place of the first collecting bottle is provided with the bottle cap corresponding with opening well, liquid can not flow out the first collecting bottle, table tennis in first collecting bottle floats, and the lower aperture of the second collecting bottle is unlimited, place a beaker in its lower section, liquid flows into beaker, table tennis in second collecting bottle is not subject to the impact of buoyancy, can not float, student is by contrasting intuitively thus clearly understanding buoyancy Producing reason, beaker pollutes table top under can preventing liquid stream.
Compared with prior art, the utility model has the advantage of: adopt this demonstration instrument, student understands to get up easily, understands more deep and thorough, successful, student convinces more, allows knowledge more simplify, and it is also easier that teacher lectures expression, and this demonstration instrument makes simple, cost is low, and the iron stand in laboratory, funnel and expense plastic bottle etc. can be adopted to make, and cost is low.
