Abstract
The utility model belongs to the technical field of teaching instruments, and specifically relates to a water plant oxygen-releasing experiment apparatus. The apparatus comprises a container (1). A plant cover (2) with an upper opening and a lower opening is arranged inside the container (1). The plant cover (2) has a small top and a big bottom. A test tube (5) is arranged on the top of the plant cover (2), and through holes (6) are arranged near a mouth of the test tube (5). Support legs (3) are arranged at the bottom of the plant cover (2). A water mark (7) is arranged at an upper part of the container (1). The top of the plant cover (2) and the mouth of the test tube (5) are provided with threads (8) for cooperation. The water plant oxygen-releasing experiment apparatus has the advantages of simple structure, convenience and practicality, and can collect oxygen released by a water plant, helping students to understand the breathing effect of the water plant underwater.
Description
Technical field
The utility model belongs to technical field of teaching instruments, and particularly a kind of hydrophyte discharges the oxygen experimental provision.
Background technology
Hydrophyte refers to those plants of normal life in water for a long time, as lotus, giantreed, reed, water lily, hornwort etc.Hydrophyte can absorb the carbon dioxide in the water, emits oxygen, plays an important role to keeping the undersurface ecologic equilibrium.The speed that hydrophyte is emitted oxygen is slowly, and naked eyes can't be observed.In the teaching of biological lesson of middle school, the mode that the teacher can only adopt preach is told the student hydrophyte absorbing carbon dioxide, the knowledge of emitting oxygen.On the other hand, middle school chemistry is produced in the oxygen experiment in the laboratory, adopts drainage to collect oxygen.
The utility model content
The purpose of this utility model provides a kind of hydrophyte and discharges the oxygen experimental provision, and this device can be collected the oxygen that hydrophyte discharges.
The scheme that the utility model solve the technical problem is: a kind of hydrophyte discharges the oxygen experimental provision, it comprises container, and the Plant hood of upper and lower opening is set in the container, and little bottom, Plant hood top is big, the top of Plant hood arranges test tube, near the test tube mouth of test tube through hole is set.
Plant hood described in the utility model refers to shroud the vessel of plant leaf.During use, hydrophyte is placed back water filling in container in the Plant hood, make water not have the top of Plant hood.After filling with water in vitro, be inverted in the top of Plant hood.Be similar to the method that oxygen is collected with drainage in the laboratory, the oxygen that hydrophyte produces can extrude invisible spectro water at leisure from through hole is set near the test tube mouth.
As further technical scheme, the bottom of described Plant hood arranges leg.
The bottom of Plant hood arranges leg, makes things convenient for Plant hood to cover tall and big plant, is conducive to the interior water of Plant hood and the circulation between the water in the container simultaneously.
As further technical scheme, the top of described container arranges watermark.
The top of container arranges watermark, the depth of water in the convenient control container.
As further technical scheme, described Plant hood is drops.
As interchangeable technical scheme, described Plant hood is the bottle shape.
As further technical scheme again, the test tube mouth of the top of described Plant hood and test tube all arranges the screw thread that cooperatively interacts.
When the material of test tube was light, test tube was not easy to be fixed on the top of Plant hood, and test tube skews easily or floats, and normal incidence in the test tube can be fixed on the top of Plant hood by screw thread.
In sum, the utlity model has simple in structure, convenient and practical advantage, can collect the oxygen that hydrophyte discharges, help the student to understand hydrophyte in undersurface respiration.
