Abstract
The invention discloses a chemical contrast rack composed of a base plate (1), vertical plates (2) and a transverse plate (3). The base plate is provided with four pits (5) and the serial numbers 1, 2, 3 and 4 (6) corresponding to the pits one by one; the transverse plate is provided with four circular holes (4) corresponding to the pits in the base plate. The chemical contrast rack has the advantages that the chemical contrast rack is used for comparison of chemical experiments and substances and recognizing chemical substances vividly, visually and clearly, students can easily identify and tell, and teaching effect is remarkable.
Description
Technical field:
The present invention relates to chemical apparatuses field, relate in particular to a kind of chemistry and compare frame.
Background technology:
Often will do in middle school chemistry teaching that material compares, experimental phenomena compares and the experiment such as identification, owing to not having special experimental apparatus, a lot of problem is always said and is not understood, says unclear, has a strong impact on the raising of quality of instruction.
Summary of the invention:
The present invention is made up of substrate (1), riser (2) and transverse slat (3).Substrate is provided with 4 depressions (5) and the numerical digit 1,2,3,4 (6) corresponding with each depression; Transverse slat is provided with 4 circular holes corresponding with the depression on substrate (4).
Advantage of the present invention is: use it do the comparison of chemical experiment and the comparison of chemical substance and differentiate chemical substance, vivid, directly perceived, distinct, student easily distinguishes, easily distinguishes, and teaching efficiency is obvious.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention, 1 substrate in figure, 2 risers, 3 transverse slats, 4 circular holes, 5 depressions, 6 numerical digits.
Embodiment:
The present invention is further illustrated below in conjunction with embodiment and accompanying drawing:
The present invention is made up of substrate (1), riser (2) and transverse slat (3).Substrate is provided with 4 depressions (5) and the numerical digit 1,2,3,4 (6) corresponding with each depression; Transverse slat is provided with 4 circular holes corresponding with the depression on substrate (4).
Advantage of the present invention uses it do the comparison of chemical experiment and the comparison of chemical substance and differentiate chemical substance, and vivid, directly perceived, distinct, student easily distinguishes, easily distinguishes, and teaching efficiency is obvious.
Claims (1)
1. a chemistry compares frame and comprises substrate (1), riser (2) and transverse slat (3), it is characterized in that substrate is provided with 4 depressions (5) and the numerical digit 1,2,3,4 (6) corresponding with each depression; Transverse slat is provided with 4 circular holes corresponding with the depression on substrate (4).
