Description
Technical field
The utility model is related to a kind of teaching aid, a kind of specifically experimental provision of observation earthworm movement.
Background technology
The experiment that the movement of earthworm is observed in junior middle school's bioconversion medium, is earthworm to be placed on coarse paper, observes earthworm
Movement.Earthworm body surface is dabbed through commonly using wet cotton balls during observation, its body is made to keep moistening.
Doing this experiment according to the method on textbook has following deficiency：
When first, is tested, earthworm usually climbs out of coarse paper, constantly it is put back to coarse paper.
2nd, is the moistening for keeping earthworm body, to dab earthworm body surface through commonly using wet cotton balls；Since earthworm is to ring around
Border reaction is very sensitive, when dabbing earthworm body surface with wet cotton balls, can significantly influence its movement.And with wet cotton
When ball wipes earthworm body surface, student is not easy to hold the weight of wiping, is easy to injure earthworm.
Often water imbibition is very strong for paper coarse 3rd, is easy that earthworm body surface is made further to lose moisture.Experiment is finished
Afterwards, l Water Paper is sticked on desktop or glass plate, to be cleaned up in time.The use of l Water Paper is typically disposable, so not only
It is bigger with water, paper using amount, and keep the clean of laboratory table, cleaning also relatively difficult.
In view of the above-mentioned problems, a kind of experiment dress of observation earthworm movement easy to operate, the clear repetitive operation of observation is good
It sets and just comes into being.
Invention content
The technical problem to be solved by the utility model is to provide it is a kind of it is easy to operate, the clear repetitive operation of observation is good
Observe the experimental provision of earthworm movement.
To achieve the above object, the utility model provides technical solution below：
Including a transparent tube body (1), tube body (1) is equipped with end cap (3), it is characterised in that：The inner wall of tube body (1)
Equipped with one piece of rough surface (2).
Further, it is preferably provided with air hole (31) on above-mentioned end cap (3).
Still further, being preferably provided with humidifier in above-mentioned tubular body (1), which includes in a tube body (1)
Cavity (42), cavity (42) at least towards tube body (1) interior side cavity wall be the mesh plate (45) equipped with hole, cavity
(42) water-absorbing sponge (44) is equipped in, the cavity wall inside of cavity (42) towards tube body (1) outer side is equipped with stripper plate (43), squeezes
Plate (43), which is equipped with, stretches out the pressure-ram (41) of cavity (42) outside.
Further, above-mentioned rough surface (2) is preferably to account for the one third of tube body (1) inner wall between 2/3rds.
Compared with prior art, the utility model is easy to operate, and intuitive is good, and observation is clear, can be that earthworm creates one
Suitable environment, device may be reused, and be easy to keep the cleaning of laboratory table, while can improve the participation and study of student
Enthusiasm promotes teaching efficiency.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model embodiment 1.
Fig. 2 is the structural schematic diagram of the utility model embodiment 2.
As shown in the figure：1 is tube body, and 2 be end cap, and 3 are, 31 be air hole, and 41 be pressure-ram, and 42 be cavity, and 43 be crowded
Pressing plate, 44 be water-absorbing sponge, and 45 be mesh plate.
Specific implementation mode
The following detailed description of preferred embodiments of the present invention.
Embodiment 1：Referring to Fig.1, it is the structural schematic diagram of the utility model embodiment 1, including cuvette shape
Tube body 1 is equipped with end cap 3 at the nozzle of 1 one end of tube body, and end cap 3 is equipped with air hole 31, and the inner wall of tube body 1 is equipped with a block size
The one third of 1 inner wall of tube body is accounted for the rough surface 2 between 2/3rds.
Embodiment 2：It is the structural schematic diagram of the utility model embodiment 2, compared with Example 1, this implementation with reference to Fig. 2
Example difference lies in：The tube body 1 is transparent straight pipe, and end cap 3 is equipped at the nozzle of 1 one end of tube body, and end cap 3 is equipped with saturating
Stomata 31, humidifier is equipped at the nozzle of 1 other end of tube body, which includes the cavity 42 in a tube body 1, cavity
42 at least towards the cavity wall of side in tube body 1 be the mesh plate 45 equipped with hole, and water-absorbing sponge 44, chamber are equipped in cavity 42
The cavity wall inside of body 42 towards 1 outer side of tube body is equipped with stripper plate 43, and stripper plate 43 is equipped with the extruding stretched out outside cavity 42 and pushes away
Bar 41,41 end of pressure-ram are equipped with handle.
Embodiment 3：Compared with Examples 1 and 2, difference in this case is that：Humidifier is integrated with end cap 3, pipe
Body 1 can be then cuvette shape, or straight-through tubulose.
Above are merely preferred embodiments of the utility model, it is noted that above-mentioned preferred embodiment should not regard
For limitations of the present invention, the scope of protection of the utility model should be subject to claim limited range.For
For those skilled in the art, without departing from the spirit and scope of the utility model, it can also make several
Improvements and modifications also should be regarded as the scope of protection of the utility model.
