In our daily life, we often see electric lights in our homes and classrooms that can light up when connected to the power supply. How do they work? Where does the electricity come from? In the following experiment, we will explore the reasons behind the bulb's light and understand how electrical circuits are connected.

Science and technology models mainly refer to land, sea, and air models. Science and technology model activities integrate science and competition, manual and brain work, and are deeply loved by a wide range of teenagers. Its main role is also to cultivate and improve the comprehensive manual innovation skills and high-quality of teenagers. Therefore, in the new form of deepening reform and vigorously promoting quality education at the turn of the century, actively carrying out science and technology model activities is an effective measure to implement quality education in an all-round way.
Expand Horizons and Enrich Scientific Knowledge
Science and technology model activities are rich in knowledge. For example, in the process of making and sailing model ships, students can learn why ships float, how ships maintain stability, why propellers generate power, how ships move fast, why the "Titanic" did not sink immediately after being hit, and why it could not avoid the iceberg. If we go deeper, students will encounter radio remote control transmitters; they will understand (or master) forces, densities, gravities, pressures, magnetic fields, ship structures, engine structures and principles, radio, material selection, and many other knowledge. Many of these are knowledge that is not in the "textbook" but is often needed in life. From this, it can inspire students to imagine boldly and make a technology model. Some may think of the inspiration from animals, such as the relationship between the fly and the airplane, the fish shape and the torpedo, and can make some simple airplane models. In this way, students will encounter and use a variety of knowledge in science and technology model activities, supplementing many book knowledge, broadening their horizons, enriching their extracurricular life, and understanding more scientific knowledge.
Cultivate logical and thinking abilities
The technology model activity requires all participants to have a dialectical, holistic, and rigorous scientific approach in their thinking methods." "Although the sparrow is small, it has all the essential organs." The tiny technology model is a scaled-down version of large, real vehicles, ships, and airplanes; it is an integrated whole, where even a slight change in one part can affect the whole.
A model airplane that competes in duration in the air must go through two stages: high-speed climb and low-speed glide. The adjustment for the climb stage mainly involves the adjustment of the pull force line and the angle of attack after the wing is twisted. The position of the center of gravity, the installation angle of the wing and the horizontal tail, and the directional rudder all have an impact on the flight attitude of the airplane during climb, but these changes directly affect the performance of the model during the gliding stage. Therefore, in the design and adjustment, it is necessary to consider these stages comprehensively, as they have different loading conditions and solutions. For example, in the design and manufacture of car, ship, and airplane models, the selection of materials for strength, rigidity, and weight is very serious. It is necessary to choose one of the best schemes from both. Therefore, in the science and technology model activities, the thinking method requires adolescents to have a dialectical, holistic, and scientific approach. Otherwise, a small mistake can make the performance of the technology model deteriorate or even fail.
It can be seen that the initial thinking of people begins with actions. The thinking characteristics of students are mainly in the form of concrete image thinking, and thinking cannot be separated from images and actions. In the process of operation activities, students need to move their eyes, move their hands, and think with their brains, speak with their mouths, so that the external operation process and the internal intellectual activities of dialectical, holistic, scientific, etc. are organically combined, which has effectively promoted their thinking development.
Three Cultivate Good Habits
Science and technology model activities are beneficial for shaping students' good personalities, cultivating their strong willpower and spirit of innovation, as well as their attention to detail and patience, forming a rigorous scientific attitude in doing things.
1. Scientific scheduling of time. Students face homework and various interests, talent cultivation, all need a certain amount of time and energy. Students must scientifically and reasonably arrange their time to achieve order and efficiency, without being overwhelmed.
2, having a beginning and an end. Nowadays, most students are only children, afraid of suffering and lack of perseverance, often give up halfway. If they choose activities that require them to use their hands and brains, let them try their best to complete a science and technology model work, their interest will rise again, because they all love to play with dynamic toys. From this perspective, it will also make them gradually overcome the laziness in the process of making, and persist in completing their own masterpieces. Thus, it also cultivates their habit of having a beginning and an end.
3, Collective Spirit. Students work together to design, create, and compete, helping, comparing, and learning from each other. This fosters a collective spirit among students, making them consider others and learn how to get along with others. In the socialist market economy, this collective spirit is essential for working together with others to create great achievements. The era of isolating themselves to boil pitch like Marie and Pierre Curie is no longer. Now, the society needs the cooperation of talent groups like the Apollo Moon Landing Project to transform the world and create the future.
Four: Stimulate students' interest in exploring the field of science and technology
A scientist or inventor, without a doubt, develops a profound interest in the things they love, and then explores and studies them, eventually achieving significant results in that field. Now, by having students create and assemble technology models, we allow them to understand the formation of power, the generation of buoyancy, and the effects of magnetic fields, laying a solid foundation for their future research and exploration in this area. This also sows the seeds of success.
In conclusion: actively developing science and technology model activities is an effective measure to implement quality education in schools, cultivate students' comprehensive development in morality, intelligence, physical, beauty, and labor, and improve their comprehensive quality. It is also an effective measure to implement the spirit of the opinions on strengthening popular science work issued by the Central Committee of the Communist Party of China and the State Council, as well as the National Fitness Program, and to fully implement the "reign in science and education" strategy proposed by the Party's 15th National Congress.
