Scientific Insights:

It is the Chinese who first discovered and used magnets. Among China's four great inventions, the compass was made using magnets. During the Warring States period, our ancestors had already gained much knowledge about magnets. When searching for iron ore, they often encountered magnetite, and these discoveries were recorded early on. Several chapters in "Guanzi" mention these findings: "On mountains there are magnetites, and beneath them there is gold and copper."

Scientific Principles:

Each magnet has positive and negative poles, and there is a magnetic field surrounding the magnet. When like poles of two magnets approach each other, the repulsive effect of the magnetic fields causes them to separate. When opposite poles of two magnets approach each other, they are attracted to each other due to the magnetic field. In simple terms, the attraction and repulsion of magnets are caused by the magnetic fields within them. This is what is referred to as like poles repelling and opposite poles attracting in physics!

Scientific Expansion:

The Earth is also a large magnet, with its two poles located near the geographic South Pole and the geographic North Pole respectively. Therefore, when the magnet on the Earth's surface rotates freely, the attraction and repulsion between like poles and opposite poles indicate north and south. The ancients did not fully understand this principle, but they were well aware of such phenomena.
After thousands of years of development, magnets have become a powerful material in our daily lives today.
By creating alloys from different materials, the same effect as a magnet can be achieved, and the magnetic force can also be enhanced.
Artificial magnets appeared in the 18th century, and in the 2020s, humans created aluminum-nickel-cobalt. Subsequently, in the 2050s, ferrites were developed, and in the 70s, rare earth magnets were created, including neodymium-iron-boron and samarium-cobalt.
Hereby, magnetic science and technology have advanced rapidly, and strong magnetic materials have also enabled components to become smaller in size.

Teaching Objectives:

1. Through experimental observation, students will understand and master that magnets have south and north poles.
2. Help students understand and master the magnetism of magnets, as well as their properties.
3. Make magnetic cars and understand how they work.

Scientific Inquiry:

1. Understand and master the properties of magnets—like poles repel each other, while opposite poles attract.
2. Understand the working principle of the magnetic toy car.

Please check that the circuit is unobstructed and all components are intact before assembly, as well as ensure all contact points are properly aligned. During assembly, be careful not to let glue get on your clothes or skin. Keep the components out of reach for younger siblings to prevent them from accidentally swallowing them! Do not play with them on your head, as the model may fall and hurt you!
