What is elasticity? And what is friction? What principle does the elusive submarine operate on? Why don't steel ships sink... With these questions in mind, the “Science Fun Experiments Series” takes you on a journey to explore the mysteries of mechanics.
This series of small experiments allow children to conduct their favorite scientific experiments without leaving home and explore the mysteries of science.
Experimental Content:
Static electricity—electric snowflakes
Introduction to the operation methods and principles
Insert the battery into the battery case and connect the circuit. The rotation of the fan blades causes the foam particles to also spin rapidly. After a few seconds, disconnect the circuit.
We found that the foam particles were adsorbed onto the inner wall of the plastic cup. This occurs because when electricity is applied, the rotation of the fan blades creates wind, which causes the foam to rise. Due to limited space, the rising foam continuously undergoes “contact and separation” with the inner wall of the plastic cup, resulting in static electricity. When the fan stops, since the foam is very light, it is easily attracted by the static electricity, which is why we see it adsorbed on the inner wall of the cup without falling down.
Cause of static electricity
In daily life, static electricity can be generated when any two objects made of different materials come into contact and then separate. When two different objects touch each other, one object loses some charge (electrons are transferred to the other object), becoming positively charged, while the other object gains some charge and becomes negatively charged. If it is difficult for the charges to cancel out during separation, the charges will accumulate, causing the objects to become charged with static electricity. Therefore, after contacting other objects and separating, the objects will carry static electricity.
Static electricity. Typically, it occurs when a plastic film is peeled off an object, which is a classic example of "contact separation" charging. In daily life, static electricity generated when removing clothes is also a form of "contact separation" charging.
We all know about triboelectricity, but few people hear about contact electrification. In essence, triboelectricity is a process where contact and separation lead to an imbalance of positive and negative charges. Friction is a continuous process of contact and separation, so triboelectricity is actually contact-separation electrification. In daily life, various objects can generate static electricity due to movement or friction.
Experimental Features:
1. Transform passive learning into active learning;
2. Shift knowledge education towards an approach that emphasizes both knowledge and skills development;
III. Transform written teaching into immersive learning to bring science to life on paper;
4. Transform indoctrination education into inspiration-based education;
5. Transform the traditional one-way teaching method into a two-way interaction between teachers and students.
Experimental results:
1. Ability to explain natural phenomena around us in simple language;
2. Ability to identify prototypes of experimental works from daily life;
III. It can enhance children’s interest in mathematics, science, and physics, as well as their academic performance;
4. It can help develop children’s ability to identify problems and solve them.
5. Experience is the key to true knowledge; ensure your child becomes a high-scoring student who doesn’t just talk about ideas on paper.
After completing the experiments, the following skills of the child can be enhanced: hands-on ability; language expression ability; mathematical, physical, and scientific abilities; observation ability; and imagination ability.
Logical thinking ability; innovation and invention capability; problem-solving skills in practical situations.
