Abstract
The utility model discloses a teaching demonstration teaching aid, which comprises a bottle body, a heating sleeve, a power supply plug, a demonstration pipe and a temperature meter, wherein the bottle body is filled with colored liquid, the lower part of the bottle body is covered with the heating sleeve, chemical reaction substances are arranged in the heating sleeve, the transparent bended demonstration pipe is inserted into the bottle through a rubber bottle cover, and the temperature meter is inserted on the rubber cover. During the demonstration, the power supply plug is plugged into a power supply, the reaction substances in the heating sleeve convert the electric energy into heat energy, the heating sleeve generates heat for heating the liquid in the bottle body, the liquid in the bottle body expands through being heated, and the expanded colored liquid goes up along the bended demonstration pipe, so the heated expansion condition of the liquid can be intuitively shown, and the utility model has the advantages of simple structure, portability, vivid and direct-viewing effect.
Description
Technical field
The utility model relates to a kind of teaching and experiment equipment, especially relates to a kind of teaching aid that can ocular demonstration liquid expands with heat and contract with cold.
Background technology
At present, expand with heat and contract with cold and the teaching of energy conversion is a important content in geographical and the physics classroom instruction, on the classroom, demonstrate by experiment, the most directly perceived, the most lively, also the easiest student's understand and master.Expand with heat and contract with cold now and energy conversion experiment is generally finished step by step by teaching aid separately, and the experimental apparatus of this part content of shortage demonstration, when doing to expand with heat and contract with cold now on the classroom with the energy conversion experiment, generally to prepare beaker before the class, seal article such as small plastic bag, cold water, hot water, balance, test tube, spirit lamp, in the assembling of top, classroom, limit experiment, the trouble that not only seems, and demonstration weak effect directly influence teaching efficiency.
Summary of the invention
The purpose of this utility model is for the above problem that overcomes on the classroom that demonstration is expanded with heat and contract with cold and exist during energy conversion, and a kind of simple in structure, demonstrating visual, easy to operate, teaching demonstration teaching aid that function is more are provided.
The purpose of this utility model is achieved through the following technical solutions, this teaching demonstration teaching aid comprises bottle, heating jacket, attaching plug, demonstration pipe, thermometer, described bottle is transparent vial, fill colored liquid in the described bottle, described bottleneck is the rubber bottle cap sealing, described bottle bottom is wrapped in heating jacket, be provided with chemical reaction substance in the described heating jacket, described heating jacket is provided with attaching plug, described one transparent bending demonstration pipe inserts in the bottle by the rubber bottle cap, also is inserted with a thermometer on the described serum cap.
During demonstration, attaching plug is inserted power supply, reactive material in the heating jacket is converted into into heat energy with electric energy, the heating jacket heating, liquid in the heating bottle, the heated liquid in the bottle expands, and rises along bending demonstration pipe behind the colored expansion of liquids, thereby can demonstrate the situation that heated liquid expands intuitively, be inserted in the temperature variations that thermometer in the bottle can show liquid in the bottle outlet.
The beneficial effects of the utility model:
1, can be clear, demonstrate out the expand situation of change of shrinkage of liquid heat intuitively.
2, the while can be showed and be shown that electric energy converts heat energy to by chemical reaction.
3, simple in structure, easy to carry, lively directly perceived.
Description of drawings
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing
Fig. 1 is a cut-open view of the present utility model
Among the figure: 1, bottle 2, heating jacket 3, attaching plug 4, demonstration pipe 5, thermometer 6, liquid 7, chemical reaction substance 8, rubber bottle cap
Embodiment
As shown in Figure 1, this teaching demonstration teaching aid comprises bottle 1, heating jacket 2, attaching plug 3, demonstration pipe 4, thermometer 5, bottle 1 is transparent vial, fill colored liquid 6 in the bottle 1, bottleneck is serum cap sealing 8, and bottle 1 bottom is wrapped in heating jacket 2, be provided with chemical reaction substance 7 in the heating jacket 2, heating jacket 2 is provided with attaching plug 3, one transparent bending demonstration pipes 4 and inserts in the bottle by rubber bottle cap 8, also is inserted with a thermometer 5 on the rubber bottle cap 8.
During demonstration, attaching plug 3 is inserted power supply, reactive material 7 in the heating jacket 2 is converted into into heat energy with electric energy, heating jacket 2 heatings, liquid 6 in the heating bottle 1, liquid 6 expanded by heating in the bottle rise along bending demonstration pipe 4 behind the colored expansion of liquids, thereby can demonstrate the situation that heated liquid expands intuitively, be inserted in the temperature variations that thermometer 5 in the bottle can show liquid in the bottle outlet.
