Abstract
The utility model discloses a biological photosynthesis teaching aid, and belongs to a teaching experimental instrument. The biological photosynthesis teaching aid comprises a box body and a gas tester, wherein the gas tester is connected below the box body; a plant is arranged in the box body; lighting lamps are arranged on four corners of the top in the box body; and a data display screen, a switch and an operation button are arranged on the gas tester. The biological photosynthesis teaching aid disclosed by the utility model is simple to operate and convenient to use, and is capable of directly showing data change of surrounding oxygen and carbon dioxide of the plant under photosynthesis, so that students can directly understand learned knowledge points.
Description
Technical field
The utility model relates to a kind of experiment equipment, specifically a kind of biological photosynthesis teaching aid.
Background technology
Classmates learn the biochron, in the explanation process of teacher for photosynthesis of plant, due to the limitation of existing experiment equipment, the variation in the time of can not making intuitively classmates understand at short notice plant generation photosynthesis causes the student not deep enough to the understanding of knowledge.
The utility model content
The purpose of this utility model is to provide a kind of biological photosynthesis teaching aid, and this teaching aid coordinates teacher to photosynthetic explanation, can show intuitively data variation.
The technical scheme in the invention for solving the technical problem is: a kind of biological photosynthesis teaching aid, comprise casing and gas determinator, described casing below connects gas determinator, four jiaos of casing inner tops are equipped with illuminating lamp, and gas determinator is provided with data display screen, switch and action button.
The beneficial effects of the utility model are: this biology photosynthesis teaching aid is simple to operate, easy to use.It can directly demonstrate the data variation of plant ambient oxygen and carbon dioxide under photosynthesis, and classmates are got more information about the knowledge point.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1 casing, 2 gas determinators, 3 illuminating lamps, 4 plants, 5 switches, 6 data display screens, 7 action buttons.
Embodiment
As shown in Figure 1.A kind of biological photosynthesis teaching aid comprises casing 1 and gas determinator 2, and described casing 1 below connects gas determinator 2, and four jiaos of casing 1 inner tops are equipped with illuminating lamp 3, and gas determinator 2 is provided with data display screen 6, switch 5 and action button 7.
When doing experiment, teacher first puts into casing 1 with a basin plant 4, plant 4 is adopted clover or other green plantss usually, opens the switch 5 of gas determinator 2, writes down the oxygen that shows on data display screen and the content data of carbon dioxide, then open illuminating lamp 3, plant is under light-illuminating fully, after a period of time, then compares with present gas content data, with proof plant absorbing carbon dioxide under photosynthesis, and releasing oxygen.
