The invention discloses a buoyancy teaching demonstration structure which comprises a bearing mechanism, a lifting mechanism, a weight measuring mechanism, weights, a water cup, a measuring cup and the like, wherein the bearing mechanism has a bearing effect; the lifting mechanism is capable of lifting the water cup and the measuring cup, and meanwhile, the weights are fixed below the weight measuring mechanism; and when the lifting mechanism carries out the lifting operation, the water cup and the measuring cup move upwards, water flows out from the water cup when the weights enter the water cup, the value displayed by the weight measuring mechanism is reduced, and the overflowing water flows into the measuring cup. After the test ends, the lifting mechanism is moved down to the position above the bearing mechanism, at the moment, the weight of the overflowing water in the measuring cup is equal to the reduced value displayed by the weight measuring mechanism, and that is to say, the buoyancy is equal to the gravity of discharged water. According to the invention, the buoyancy test is precisely demonstrated, the integral structure is reasonable, the operation is simple, the interesting teaching is ensured, and the buoyancy teaching demonstration structure can be widely applied to physical teaching.
Description
technical field [0001] The invention relates to a physics teaching tool, in particular to a buoyancy teaching demonstration structure. Background technique [0002] When students learn book knowledge, they are assisted by teaching aids and experimental devices, which are of great help to deepen the understanding and mastery of the knowledge they have learned, especially for students who are new to buoyancy and other related knowledge. Experimental equipment is very necessary. In the existing physics teaching, there is a lack of such in-class experimental devices. Teachers either rely entirely on book knowledge for teaching, or make some non-standard self-made teaching aids to help students understand physics knowledge. The actual teaching purpose can not achieve the ideal effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a buoyancy teaching demonstration structure, which can solve the above-mentioned prob...
