Abstract
Buoyancy produces experiment device for principle, comprise water storage container, sink-float storehouse, rule, suspension member, baton round, it is characterized in that: water storage container is transparent cylinder plastic bottle, inwall upper end is provided with suspension member (mother) slot, sink-float storehouse is the transparent cylindrical ampuliform of reversal of the natural order of things at water storage container, bottle wall is provided with rule, every scale is divided into 1 centimetre mutually, top is provided with gap and suspension member (public affairs) is inserted slightly, lower end is bottleneck and water delivering orifice, bottleneck is less than baton round, the pressure that baton round is subject to water downward gets lodged in bottleneck, water can not toward dirty, suspension member is public and parent phase is identical, sink-float storehouse hangs over water storage container inwall upper end.During experiment, baton round is put into sink-float storehouse, spherome surface and bottleneck coincide, block water delivering orifice, water injects from sink-float upper end, storehouse, and water can not toward dirty, and water also loses baton round after filling sink-float storehouse and floats, continue water filling, water flows into water storage container from gap, and the water surface slowly raises, and observes water level at how many scales, when to write down drop be several centimetres, baton round floats.
Description
Technical field
Buoyancy produces experiment device for principle and relates to the teaching aid and learning aid that a kind of junior physics water has buoyancy experiment to impart knowledge to students, and the natural sciences experimental apparatus device of scientific exploration is carried out in everybody hands-on of a kind of applicable student to the principle that buoyancy produces.
Background technology
In junior physics (people teaches version) first " buoyancy " unit, only with legend methods analyst, water-immersed cubical six surface are subject to the fluid pressure of different directions to teaching material, draw the pressure differential up and down that buoyancy equals object and is subject to.The knowledge such as relation, two power that will use liquid pressure and the degree of depth in analysis are synthesized, balance between two forces, the power related to is more, adds the difficulty that student understands these knowledge.
Summary of the invention
The utility model buoyancy produces experiment device for principle, comprise water storage container, sink-float storehouse, rule, suspension member, baton round, it is characterized in that: water storage container is transparent cylinder plastic bottle, opening upwards, inwall upper end is provided with suspension member (mother) slot, sink-float storehouse is the transparent cylindrical ampuliform of reversal of the natural order of things at water storage container, bottle wall is provided with rule, every scale is divided into 1 centimetre mutually, top is provided with gap and suspension member (public affairs) is inserted slightly, lower end is bottleneck and water delivering orifice, bottleneck is less than baton round, the pressure that baton round is subject to water downward gets lodged in bottleneck, water can not toward dirty, suspension member is public and parent phase is identical, sink-float storehouse hangs over water storage container inwall upper end.During experiment, baton round (using table tennis generation) is put into sink-float storehouse, spherome surface and bottleneck coincide, block water delivering orifice, water injects from sink-float upper end, storehouse, and water can not toward dirty, and water also loses baton round after filling sink-float storehouse and floats, continue water filling, water flows into water storage container from gap, and the water surface slowly raises, and observes water level at how many scales, when to write down drop be several centimetres, baton round floats.Beneficial effect: clearly observe sink-float storehouse bottleneck and baton round is divided into upper and lower two parts, baton round top is subject to being subject to water storage container water from the downward pressure of sink-float Cang Shui and bottom and upwards pressure, there is pressure differential in these two pressure, along with the continuous injection of water, this pressure differential is more and more less, when arriving certain value, baton round just floats.
Accompanying drawing explanation
Accompanying drawing 1 is that buoyancy produces experiment device for principle schematic diagram of device.Sequence number by figure: 1. water storage container, 2. rise and fall storehouse, 3. rule, 4. gap, 5. suspension member, 6. water delivering orifice, 7. baton round.
Embodiment
Buoyancy produces experiment device for principle, comprise water storage container, sink-float storehouse, rule, suspension member, baton round, it is characterized in that: water storage container (1) is a transparent right cylinder plastic bottle, opening upwards, inwall upper end is provided with suspension member (5) female plug groove, sink-float storehouse (2) is the transparent cylindrical ampuliform of reversal of the natural order of things on water storage container inwall, bottle wall is provided with rule (3), every scale is divided into 1 centimetre mutually, top is provided with gap (4), outer wall upper end is provided with suspension member (5) male plug slightly, lower end is bottleneck and water delivering orifice (6), bottleneck is less than baton round (7), baton round is subject to gravity and the downward pressure of water gets lodged in bottleneck, water can not toward dirty, suspension member is public and suspension member parent phase is identical, sink-float storehouse hangs over water storage container inwall upper end.During experiment, baton round (available table tennis generation) is put into sink-float storehouse, spherome surface and bottleneck coincide, block water delivering orifice, water injects from sink-float upper end, storehouse, and water toward dirty, can not can be observed peculiar phenomenon: water also loses baton round after filling sink-float storehouse and floats, continue water filling, water flows into water storage container from gap, and the water surface slowly raises, and observes water level at how many scales, water level is probed in water storage container in observation when being several centimetres with water level two height of water in sink-float storehouse, and baton round floats.
Claims (1)
1. buoyancy produces experiment device for principle, comprise water storage container, sink-float storehouse, rule, suspension member, baton round, it is characterized in that: water storage container is a transparent right cylinder plastic bottle, opening upwards, inwall upper end is provided with suspension member female plug groove, sink-float storehouse is the transparent cylindrical ampuliform of reversal of the natural order of things on water storage container inwall, bottle wall is provided with rule, every scale is divided into 1 centimetre mutually, top is provided with gap, outer wall upper end is provided with suspension member male plug slightly, lower end is bottleneck and water delivering orifice, bottleneck is less than baton round, baton round is subject to gravity and the downward pressure of water gets lodged in bottleneck, water can not toward dirty, suspension member is public and suspension member parent phase is identical, sink-float storehouse hangs over water storage container inwall upper end.
