Abstract
A physical teaching aid comprises a plastic bottle, a cartesian diver and a pressure regulator, wherein the pressure regulator comprises a collar and a pressure regulating rod, and the pressure regulating rod is marked with a scale; one end of the collar is fixedly connected with the pressure regulating rod, and the other end of the collar is movably connected with the pressure regulating rod through a clamp part; the pressure regulator is clamped and sleeved in the middle of the plastic bottle, and the plastic bottle contains purified water; and the cartesian diver is disposed in the plastic bottle and floats in the purified water, and the cartesian diver is a transparent shell with one end having a capsule and the other end openmouthed. The physical teaching aid is simple in structure, strong in operability, and capable of demonstrating the buoyancy generation process.
Description
Technical field
The utility model relates to a kind of physical teaching aid, particularly relates to a kind of teaching aid of demonstrating sink-float principle.
Background technology
At present, middle and primary schools' teaching aid kind is a lot, but there is no the educational aid of ocular demonstration floating dust principle, thereby to teaching, brings certain difficulty, even has influence on student's learning interest.
The utility model content
The purpose of this utility model is to overcome the prior art above shortcomings,, by Improvement, provides a kind of teaching aid of demonstrating sink-float principle.This novel teaching aid is simple in structure, workable, can demonstrate the process that sink-float produces.
The technical scheme that the utility model provides is: this physical teaching aid is comprised of plastic bottle, Cartesian diver, pressure regulator, pressure regulator consists of collar and pressure regulation bar, the pressure regulation bar is marked with scale, collar one end is fixedly connected with the pressure regulation bar, and the other end uses fastener and pressure regulation bar to be flexibly connected, and pressure regulator is fastened in the plastic bottle middle part, holding pure water in plastic bottle, Cartesian diver in this plastic bottle, swims in pure water, and this Cartesian diver is that an end band capsule, the other end are uncovered transparent bottle.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
Physical teaching aid is comprised of plastic bottle 1, Cartesian diver 2, pressure regulator 3, pressure regulator 3 consists of collar 31 and pressure regulation bar 32, pressure regulation bar 32 is marked with scale, collar 31 1 ends are fixedly connected with pressure regulation bar 32, the other end uses fastener 311 and pressure regulation bar 32 to be flexibly connected, pressure regulator 3 is fastened in plastic bottle 1 middle part, the interior holding pure water of plastic bottle 1, and pass through bottle cap sealing, Cartesian diver 2 is in this plastic bottle 1, swim in pure water, this Cartesian diver 2 is that an end band capsule, the other end are uncovered transparent bottle.
Be sticked in by fastener 311 on the different scales of pressure regulation bar 32, the pressure in increase and decrease plastic bottle 1, finally make Cartesian diver 2 drift along up and down.
By demonstration, the student is intuitively grasped: the knowledge point of buoyancy and pressure relation, submarine boat sink-float principle and liquid transaudient.
