The ability of practice of starting, training student, to natural science applied hobby, by directly perceived, lively observation, is easy to students
The natural science knowledges such as plant, insecticide, inspire creative thinking ability, it is happy that experience group member works in unity and helps one another.
2. this demonstration teaching aid component is few, makes easily, simple to operate, is suitable as the Science Teaching of pupil colony
Apparatus carries out penetration and promotion application.
3. pass through the single convex lenss of setting-in two on lid and can increase amplification, be easy to examine.
4. lure insect motion by setting up solar energy audible-visual annunciator, improve observing effect, student can be widened simultaneously
Popular science knowledge, excite great interest.
Brief description
Fig. 1 is structural representation of the present utility model.
In figure：1- grid lamella lucida, 2- transparent observing box, the horizontal rule of 3-, 4- longitudinal direction rule, the mono- convex lenss of 5-,
6- solar energy audible-visual annunciator, 7- rectangle draw hole, 8- circle drawing hole, 9- concentric circular observation area, 10- horizontal concrete chute, 11- indulges
To chute, 12- lid, 13- rib.
Specific embodiment
Below by embodiment and combine accompanying drawing this utility model is described in detail.
A kind of this utility model as shown in Figure 1 Science Teaching demonstration teaching aid, including grid lamella lucida 1, transparent sight
Examine box 2, horizontal rule 3, longitudinal rule 4, single convex lenss 5 and solar energy audible-visual annunciator 6, grid lamella lucida 1 is provided with
Rectangle draw hole 7, circular drawing hole 8 and concentric circular observation area 9, can place what various needs were observed in concentric circular observation area 9
Plant leaf, insecticide etc., can draw bubble chart by rectangle draw hole 7 and circular drawing hole 8 to the result observed, grid is saturating
