Abstract
The utility model relates to experimental equipment, and provides an object floating and sinking experimental instrument. The instrument comprises a plastic bottle with an upper cover. A duct is mounted on the upper cover of the plastic bottle, and one end of the duct is connected with a syringe. A Cartesian diver is arranged inside the plastic bottle. The Cartesian diver is a rubber dropper head. A lead block is mounted at the aperture of the rubber dropper head. The plastic bottle is filled with water. The object floating and sinking experimental instrument provided by the utility model has the advantages of simple structure, easy production, easy operation, obvious and intuitive experiment phenomena, easily available raw materials and low cost, and is capable of demonstrating physical principles in a clear and understandable manner. The instrument can be used as either a teaching instrument or an after-school little experiment instrument for students.
Description
Technical field
The utility model relates to a kind of experimental provision, is specifically related to a kind of object floating experiment instrument.
Background technology
The teaching of a lot of physics aspect while relating to some principle, is difficult to understand for beginner.Teacher's the explanation of eating dishes without rice or wine also allows some students not understand or be difficult to remember.Not allowing by concrete operation experiments, learner is more understandable more easily to be remembered in such teaching.At present, for most experimental provision complex structure of physics teaching, the scope of application is wideless.And the almost not basic Experiment of Principle to Physics Learning and the experimental provision made on market, causing rigidly connecting tactile physical students in middle and primary schools cannot be clear understandable to basic physics knowledge, add some theoretical property concepts physically, if do not explained orally analysis, be difficult to allow those students of begining to learn understand, thereby make most students lose learning interest.
Utility model content
Technical problem to be solved in the utility model is to provide obviously object floating experiment instrument intuitively of a kind of simple in structure, easy making, easy to operate, experimental phenomena.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of object floating experiment instrument, it is characterized in that: comprise a plastic bottle with upper cover, on described plastic bottle, cover conduit is installed, conduit one end connects a syringe, in plastic bottle, be provided with a sinking-floating object, described sinking-floating object is glue head dropper head, and the bore place of glue head dropper head is provided with lead, is marked with water in plastic bottle.
Described conduit is rubber hose, is connected with plastic bottle upper cover by one section of hard plastic tube.
Described lead is spheroid, and the diameter of lead is greater than the diameter in glue head dropper draught animals footpath, and the water in plastic bottle can not enter in glue head dropper head.
The beneficial effects of the utility model are: the utility model making simple in structure, easy, easy to operate, experimental phenomena is obviously directly perceived, make that raw material is easy to get, cost is low.What physical principle was demonstrated is clear understandable, can be used as instruments used for education and uses, and also can be used as the outer little experimental apparatus of students in class.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
A kind of object floating experiment instrument as shown in Figure 1, comprise a plastic bottle 1 with upper cover, on plastic bottle 1, cover conduit 2 is installed, conduit 2 one end connect a syringe 3, in plastic bottle 1, be provided with a sinking-floating object 4, sinking-floating object is glue head dropper head 5, and the bore place of glue head dropper head 5 is provided with lead 6, in plastic bottle 1, is marked with water.Conduit 2 is rubber hose, is connected with plastic bottle 1 upper cover by one section of hard plastic tube.Lead 6 is spheroid, and the diameter of lead 6 is greater than the diameter of glue head dropper head 5 bores.
Pushing syringe piston rod is squeezed into air in plastic bottle, and Cartesian diver sinks.Pull out piston, deflate, Cartesian diver floating.In plastic bottle, squeeze into appropriate air, Cartesian diver can be suspended in the middle of water.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and instructions, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
