Electrostatic—Electric Snowflake
Introduction to Operation Methods and Principles
Insert the battery into the battery box and connect the circuit, and the rotation of the fan blades will drive the foam particles to rotate rapidly. After a few seconds, disconnect the circuit.
We found that foam particles were adsorbed on the inner walls of the plastic cup. This is because after the fan starts spinning, the wind generated by the fan blades causes the foam to fly up. Due to the limited space, the flying foam continuously makes "contact separation" with the inner walls of the plastic cup, generating static electricity. After the fan stops, since the foam is very light, it is easily attracted by static electricity, so we see them adsorbed on the inner walls of the cup and do not fall off.
The cause of static electricity
In daily life, any two objects made of different materials that come into contact and then separate can generate static electricity. When two different objects touch, one object loses some charge (electrons transfer to the other object), resulting in a positive charge, while the other object gains some charge, resulting in a negative charge. If during the separation process, the charge is difficult to neutralize, the charge will accumulate, making the object static, so when an object comes into contact with another object and then separates, it will have a static charge.
Static electricity. It is a typical "contact-separation" electrostatic phenomenon when a plastic film is peeled off from an object. In daily life, static electricity generated by taking off clothes is also a "contact-separation" electrostatic phenomenon.
We all know that friction generates electricity, but we rarely hear of contact generating electricity. In fact, friction generates electricity is a process caused by contact and separation that leads to an imbalance in positive and negative charges. Friction is a continuous process of contact and separation, so the essence of friction generating electricity is actually contact and separation generating electricity. In daily life, various objects may generate static electricity due to movement or friction.
Experimental features:
1. Transform passive learning into active learning;
II. Transform knowledge education into one that emphasizes both knowledge and ability;
Three, transform written teaching into three-dimensional teaching, allowing science to "fly" off the paper;
Fourth, transform indoctrination education into enlightenment education.
V. Transform the traditional single-sided teaching method into a two-way interaction between teachers and students.
Experimental results:
1. Ability to explain natural phenomena around us in layman's terms;
2. Able to discover the prototype of experimental works from daily life;
Three, can enhance children's interest in mathematics and science and improve their academic performance;
Fourthly, it can cultivate children's ability to identify problems and solve practical problems;
V. Practice reveals the truth, so that your child no longer becomes a high-scoring talent who only talks about war from afar.
Experiments can enhance the following abilities in children -- practical ability; language expression ability; mathematical and physical ability; observation ability; imagination ability.
Logical thinking ability; innovative and inventive ability; the ability to solve practical problems.
