Scientific Enlightenment:

The Chinese people discovered and used magnets, and the "compass" is a product of using magnets. Our ancestors in the Warring States period had accumulated a lot of knowledge about magnets. When exploring iron mines, they often encountered magnetite. These discoveries were recorded early. The "Guanzi" has early records of these discoveries: "There is magnetite on the mountain, there is gold and copper below."

Scientific Principles:

Every magnet has both a north and south pole, and around it is a magnetic field. When two magnets of the same pole approach each other, they are repelled by the mutual repulsion of the magnetic fields and move apart. When two magnets of different poles approach each other, they are attracted to each other under the influence of the magnetic field. In short, the attraction and repulsion of magnets are caused by the magnetic field within the magnets. This is what is referred to in physics as like poles repel each other, while unlike poles attract each other!

Science Expansion:

The Earth is also a large magnet, with its two poles located near the geographical South Pole and the geographical North Pole. Therefore, when a magnet on the Earth's surface is allowed to freely rotate, it will indicate the direction of north and south due to the properties of magnetism, which repel each other when they are of the same polarity and attract each other when they are of opposite polarity. The ancients did not fully understand this principle, but they were well aware of such phenomena.
After thousands of years of development, today, magnets have become a powerful material in our lives.
By synthesizing alloys with different materials, one can achieve the same effect as a magnet, and even enhance the magnetic force.
In the 18th century, artificial magnets appeared, and in the 1920s, humans began to manufacture aluminum-nickel-cobalt. Subsequently, ferrite was manufactured in the 1950s, and rare earth magnets, including neodymium iron boron and samarium cobalt, were manufactured in the 1970s.
To this point, the development of magnetism technology has progressed rapidly, and the use of strong magnetic materials has enabled components to become even more miniaturized.

Teaching objectives:

1. By observing experiments, let students understand and master that a magnet has two poles: south and north.
2. Help students understand and master the magnetic force of magnets and their properties.
3. Make a magnet car and understand the working principle of the magnet car.

Scientific Inquiry:

1. Understanding and mastering the properties of magnets - like poles repel each other, while opposite poles attract each other.
2. Master the working principle of the magnet car.

  Before assembling, please check if the circuit is unblocked and all the components are complete. Ensure that all contact points are in good contact. During the assembly process, be careful not to get glue on your clothes or skin. Keep the parts out of reach of younger siblings to prevent them from swallowing them by mistake! Do not play with them on your head, to avoid the model falling and injuring you!
