A fun little experimental device

Abstract

The invention discloses an interesting small experiment device. For the interesting small experiment device, the experimental simulation for various natural phenomena, such as the buoyancy of water, the dynamics of air flow, the back flushing and the effect of wind can be realized, so that the cognitive competence of the students, especially the pupils for the nature can be effectively improved, and thus the experiment effect is improved. The interesting small experiment device is simple in structure, the experiment is convenient, and the simulation for the wind can be realized by utilizing blowing assemblies, so that the influences of the wind on sails or boats can be displayed; by utilizing air flow jetting assemblies, the demonstration for the back flushing and the dynamics of air flowcan be realized, meanwhile, the angle can be adjusted, and thus the back flushing principle can be deeply understood; and due to the telescopic arrangement of a floating body, the buoyancy can be effectively demonstrated, meanwhile, sinking display rules are used for displaying the sinking amount, thus the demonstration for the buoyancy is realized, and moreover, due to the detachable arrangementof the floating body, the stretching and contracting as well as various assembly modes and the like can be conveniently carried out.

Description

technical field [0001] The invention relates to the technical field of demonstration or interesting small experimental equipment, in particular to a small interesting experimental device. Background technique [0002] For children, curiosity is the driving force that drives them to explore the world and learn knowledge. At present, there are more and more small experimental devices in school learning and fun games at home. These small experimental devices can enhance students' learning fun, improve their cognitive ability to the world and their understanding of learned knowledge. In daily life, the buoyancy of water, airflow dynamics, recoil, the effect of wind, etc. can be seen everywhere. However, it is difficult for primary school students and other children to understand the principles and phenomena of these knowledge. And if it is demonstrated in the way of interesting small experiments, it can improve its fun, realize classroom interaction, and enhance its interest in...
