Abstract

The invention relates to an electric diagram for translocation. The electric diagram for the translocation can display the process of conveying water in a guide tube from bottom to top and the process of conveying organic matter in a sieve tube from top to bottom in the translocation of plants. A red light band represents the guide tube, the flashing of red light represents the process of conveying the water in the guide tube from bottom to top, a yellow light band represents the sieve tube, and the flashing of yellow light represents the process of conveying the organic matter in the sieve tube from top to bottom. The electric diagram is applied to the teaching related to the related content of translocation in biology of a junior high school and enables the teaching of the translocation of the plants to be vivid and interesting, the aim of breaking through key teaching points and difficult teaching points is achieved, and the teaching effect is good.

Description

The electronic diagram of translocation

Affiliated technical field

The present invention relates to the electronic diagram of a kind of translocation, it is a kind of can the demonstration in the plant translocation, moisture transportation and organism electronic diagram of the translocation of top-down transportation in screen casing from bottom to top in conduit, the red globe lamp band means conduit, the glittering expression moisture of red light transportation from bottom to top in conduit, the yellow fluorescent lamp band means screen casing, glittering expression organism top-down transportation in screen casing of yellow light.

Background technology

At present, also there is no the invention of this respect.

Summary of the invention

The invention provides the electronic diagram of a kind of translocation, the electronic diagram of this translocation can show in the plant translocation, moisture transportation and organism electronic diagram of the translocation of top-down transportation in screen casing from bottom to top in conduit, the red globe lamp band means conduit, the glittering expression moisture of red light transportation from bottom to top in conduit, the yellow fluorescent lamp band means screen casing, glittering expression organism top-down transportation in screen casing of yellow light.

The technical solution adopted for the present invention to solve the technical problems is: utilize the principle design that two core fluorescent tubes can be walked about under the control of walking the lamp machine to make, the PVC plastic tube that is 150mm with long 850mm, diameter is as stem, in chord length, be 100mm place rip cutting from top to bottom 700 long mm, laterally cut herein, lower part is as base; The plastic plate long with 700mm, that 100mm is wide, 3mm is thick is made profile; The PVC plate that is 150mm, thick 5mm with diameter is done square section, shows xylem and bast; Show two conduits with red two core lamp band 2000mm; Yellow two core lamp band 2000mm show two screen casings; AWG copper core electric wire 5000mm, each, No. 20 iron wire 1000mm, green and yellow switches; Conduit, screen casing, xylem, bast title word indicating; Two core lamp bands and electric wire connection place use pin as binding post.

Using method: 1, teaching aid is said right, switched on power.2 if, in the demonstration translocation, moisture transporting from bottom to top in the conduit of xylem, open green switch, and red colored lamp is bright.3 if, in the demonstration translocation, organism is top-down transporting in the screen casing of bast, opens yellow switch, and amber light is bright.4 if, in the demonstration translocation, moisture transporting and organism top-down transporting in the screen casing of bast from bottom to top in the conduit of xylem, just open green and yellow switch redness and amber light together bright simultaneously.

Points for attention: 1, should cut off the electricity supply immediately after finishing using.2, be finished and install with Dust-proof bag afterwards, keep properly.

The invention has the beneficial effects as follows, can show in the plant translocation, moisture transportation and organism electronic diagram of the translocation of top-down transportation in screen casing from bottom to top in conduit, the red globe lamp band means conduit, the glittering expression moisture of red light transportation from bottom to top in conduit, the yellow fluorescent lamp band means screen casing, glittering expression organism top-down transportation in screen casing of yellow light.Teaching for the relevant translocation related content of junior middle school's biology, can make the teaching of plant translocation vivid, vivaciously interesting, reaches the purpose that breaks through focal points, difficult point, and teaching efficiency is good.
