Abstract

The utility model relates to a teaching demonstration instrument, in particular to a device used for demonstrating the experiment, during which the oxygen generated through the plant photosynthesis in junior high school biology teaching. The utility model adopts structure as following: one end of a transparent reaction cabin (1) is closed, and the other end is an material inlet (7), the material inlet (7) adopts a sealed turning cap (2) structure, a water inlet pipe (3) and an air collecting chamber (4) are respectively arranged at the top of the reaction cabin (1), a rubber plug (5) is installed at an air outlet in a sealed way at the top of the transparent air collecting chamber (4), and an air exhausting hose (6) connected with the inside and the outside is inserted into the rubber plug (5). The device has the advantages that the carrying is convenient, the operation is easy, the effect is obvious, and the device is suitable for using repeatedly.

Description

The photosynthesis reaction unit
Technical field
The utility model relates to a kind of teaching demonstration instrument, specifically, is a kind of device that biological teaching demonstration photosynthesis of plant produces oxygen and tests in the junior middle school that is used for.
Background technology
Photosynthesis is the important content in the middle of the biological textbook in junior middle school, in order to represent the oxygenous overall process of photosynthesis to the student more intuitively, passes through to adopt the way of lecture experiment usually in teaching.At present, generally form an easy device with beaker, funnel, test tube and do this lecture experiment, and there are some shortcomings in this device: 1. experimental provision is open, and water is completely easily splashed, and carries inconvenience; 2. the pasture and water under the funnel squeeze a ball, and light-receiving area is little, and photosynthesis carries out slowly, and experimental phenomena is not obvious, often failure; 3. the oxygen of Shou Jiing can only be demonstrated once, is not suitable for parallel class teaching demonstration, has strengthened teacher's workload; 4. operative technique relatively requires height, probes into experiment for student's grouping and is not suitable for promoting.
The utility model content
The purpose of this utility model be to provide a kind of easy to carry, simple to operate, effect obviously, be fit to the photosynthesis reaction unit that repeatedly uses repeatedly.
The purpose of this utility model is achieved through the following channels: the transparent reaction storehouse 1 one ends sealing of photosynthesis reaction unit, the other end is a charging aperture 7, charging aperture 7 adopts spiral cover 2 structures of sealing, the top of reaction warehouse 1 is respectively equipped with water inlet pipe 3 and collection chamber 4, the gas outlet at transparent collection chamber 4 tops is sealed and installed with rubber stopper 5, the exhaust hose 6 that connection of rubber stopper 5 interpolations is inside and outside.The top of described water inlet pipe 3 is a funnel structure, and water inlet pipe 3 exceeds more than 1 times of collection chamber 4 height.Accompany vessel clamp 8 on the described exhaust hose 6.Reaction warehouse 1 Lower Half is goed deep in described water inlet pipe 3 bottoms.
The utility model photosynthesis reaction unit is compared the current experiments device, has following characteristics:
1. draw materials easily, make simple, reusable.
2. the bubble that produces of photosynthesis, more faster, phenomenon is more obvious.
3. use, easy to carry.
4. can collect more gas, and controllability emits, be applicable to the teaching of parallel class.。
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, the utility model photosynthesis reaction unit structure is as follows: the sealing of reaction warehouse 1 one ends, the other end is a charging aperture 7, charging aperture 7 adopts spiral cover 2 structures of sealing, the top of reaction warehouse 1 is respectively equipped with water inlet pipe 3 and collection chamber 4, the top of water inlet pipe 3 is a funnel structure, water inlet pipe 3 exceeds more than 1 times of collection chamber 4 height, reaction warehouse 1 Lower Half is goed deep in water inlet pipe 3 bottoms, the gas outlet at collection chamber 4 tops is sealed and installed with rubber stopper 5, the exhaust hose 6 that connection of rubber stopper 5 interpolations is inside and outside accompanies vessel clamp 8 on the exhaust hose 6.
For the ease of observation of students, reaction warehouse 1, collection chamber 4 in the utility model photosynthesis reaction unit structure are all made as glass, plastic or other material by transparent.
The specific operation process of the photosynthesis reaction unit of the utility model device is as follows:
1. open the spiral cover 2 of charging aperture 7, with the hornwort reaction warehouse 1 of packing into;
2. hornwort is good at reaction warehouse 1 internal fixation, it is fully unfolded, improve photosynthetic reaction efficiency;
3. tighten the spiral cover 2 of charging aperture 7, sealed reaction storehouse 1;
4. take off the vessel clamp 8 on the exhaust hose 6, from the funnel injection clear water at water inlet pipe 3 tops, (every 100mL water adds the 0.1g sodium bicarbonate, stir with glass bar, to increase the content of carbon dioxide in the water, reaction of propagation time), when collection chamber 4 water are full, clamp vessel clamp 8, stop water filling
5. the photosynthesis reaction unit is placed on irradiation under the sunlight, can see that soon transparent reaction storehouse 1 interior hornwort carries out photosynthesis and produces some little rills, growth in time, can see that a large amount of bubbles rises to the top of reaction warehouse 1, and slowly enter collection chamber 4, and make collection chamber 4 liquid levels constantly descend, the liquid level of water inlet constantly rises, about 2-4 hour, the full gas of collection chamber 4 collection.
6. can test to collection chamber 4 gases then, the ignition substance of band Mars is put to exhaust hose 6 oral areas, open vessel clamp 8, the gas of collection chamber 4 is emitted and is made the ignition substance resume combustion, clip vessel clamp 8, can carry out the experiment second time, when oxygen is not enough, can once more the photosynthesis reaction unit be put to sunlight and carry out photosynthesis for test use next time.

Claims (4)
