Abstract
The utility model relates to a teaching model, belonging to the technical field of teaching aids, and characterized in that a main body of the model is two rectangle strip structures (1) which are in connection through hinges (3) to represent a sister chromatid. A right side and a reverse side of the main body of the model have different colors and a same shape, represent a homologous chromosome and are respectively provided with two magnets (2). The magnets on one hand represent the centromere of the chromosome and on the other hand stick the homologous chromosome. The magnets can be installed in the central section of the main body of the model, or can be installed on the upper section or the lower section. Those with a consistent color can be prescribed to be in a same group.
Description
Technical field
The utility model relates to the chromosome teaching mode that a kind of bioconversion medium is used, and belongs to the teaching aid technical field.
Background technology
Meiosis is emphasis and the difficult point in the Biology Teaching, and the abstract indigestibility of content is necessary to adopt intuitively teaching aid to help this partial content of students understand to this situation.Have a relevant patented technology, " a kind of chromosome teaching mode " (201549100) on the home market at present.This fabrication techniques is simple, and is directly perceived.But this model does not show sister chromatids.Given this, I improve original technology.
Summary of the invention
The purpose of the utility model is to provide a kind of teaching mode of chromosome intuitively, and this model can help the explanation subtrahend of teacher image to separate this part, also can let the student oneself demonstrate after class, understands chromosomal variation in the meiosis process.
The utility model solves the technical scheme that its technical matters adopted: the model main body is two rectangular list structures, and both link to each other through loose-leaf and represent sister chromatids.The pro and con color of model main body however with, but shape is identical, the pro and con of main body is represented homologue.At the tow sides of model main body two blocks of magnet are installed respectively; Magnet can be installed in the middle part of model main body, also can be installed in top or bottom, and the effect one of magnet is the chromosomal kinetochore of representative; On the other hand that homologue is glutinous together, not only saved the space but also prevented loss.
The used material of the utility model main body can be a timber, also can use plastics.
The beneficial effect of the utility model is: simple in structure, with low cost, scientific and reasonable.Adhesive through magnet is demonstrated chromosomal fission process with separating; Two rectangular strip structures through folding main body are represented a chromosome, both are trailed then represent sister chromatids.Can vivid explanation meiosis process.
Description of drawings
Fig. 1 is the structural representation of the utility model; Fig. 2 is the rear view of Fig. 1.
Among the figure: 1. rectangle is rectangular, and 2. magnet 3. folds loose-leaf
Embodiment
As shown in Figure 1, the main body of model is two rectangular list structures, and both link to each other through loose-leaf and represent sister chromatids.The pro and con color of model main body however with, but shape is identical, the pro and con of main body is represented homologue.At the tow sides of model main body two magnet are installed respectively, magnet can be installed in the middle part of model main body, also can be installed in top or bottom, and the effect one of magnet is the chromosomal kinetochore of representative, and is on the other hand that homologue is glutinous together.Demonstrate chromosomal fission process through the adhesive of magnet with separating then; Two rectangular strip structures through folding main body are represented a chromosome, both are trailed then represent sister chromatids.This process can let the student do it yourself to operate, and abstract process is become visual in image.
This utility model technology is simple, with low cost, is adapted at rural middle school and uses.
Claims (4)
1. a chromosome teaching mode is characterized in that main body is two rectangular list structures, and body portion pro and con, the tow sides of main body are respectively installed two blocks of magnet.
2. chromosome model according to claim 1 is characterized in that two rectangle strip structures that constitute main body link to each other through loose-leaf.
3. chromosome model according to claim 1, it is characterized in that main body the pro and con color otherwise with, but shape is identical.
