Abstract
The utility model relates to physics experiment teaching aid, especially a experiment device for verifying Archimedean principle, wherein the experiment device for verifying Archimedean principle is composed of an iron support, a spring balance, a glass, a syringe, an object to be tested, a measuring cup, a basket, characterized in that the lower end of the spring balance is connected with the basket, the glass is contained in the basket, the object to be tested is hung on lower end of the basket, the spring balance is hung on upper end of the iron support, the measuring cup is placed on the iron support, the syringe is used for pumping water during experiment. The utility model has advantages of simple structure, intuitive and convenient experiment results, indicating the comparison result via pointer position of the spring balance.
Description
Technical field
The utility model belongs to the Physical Experiment teaching aid, particularly a kind of checking Archimedes principle experimental provision.
Background technology
At present, the teaching aid of existing Physical Experiment Archimedes principle utilizes a spring balance and an iron block and one glass of glass cylinder that is filled with water to divide the experiment of three steps, and top experimental technique demonstration step is many, and the student thought span is big.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of Archimedes principle experimental provision that goes to verify, this experimental provision immerses measured object in the water, liquid level rises, with syringe the water of rising part is extracted out, inject glass cylinder, equate that experimental procedure one goes on foot successfully before observing spring balance indication numerical value and not putting into measured object.
The technical scheme in the invention for solving the technical problem is: a kind of check Archimedes principle experimental provision, form by iron stand, spring balance, glass cylinder, syringe, measured object, measuring cup, basket, its special character is: the spring balance lower end is connected to a basket, glass cylinder is housed in the basket, measured object hangs over the basket lower end, and the iron stand upper end hangs with spring balance, and measuring cup is placed on the iron stand, during experiment, draw water with syringe.
The beneficial effects of the utility model are: simple, directly perceived, experiment one goes on foot successfully, and comparative result directly illustrates by the spring balance pointer position.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
In the accompanying drawing: 1 iron stand, 2 spring balances, 3 glass cylinderes, 4 syringes, 5 measured objects, 6 measuring cups, 7 baskets.
Embodiment
