Make science and technology small inventions in the following ways:
1, simple drone: use some electronic parts and materials, such as motors, batteries, remote control, PVC pipe, etc., to assemble a simple drone. You can design and assemble it according to your own needs and skills to realize the basic functions of the drone, such as flying and shooting.
2, solar charger: use solar panels and batteries to make a simple solar charger. It can charge cell phones or other electronic devices in the sunlight, which is very environmental and practical.
3, homemade telescope: make a simple telescope using some lenses and mirrors, and some simple tools and materials, such as cardboard, glue, rulers and so on. You can adjust the distance and angle of the lens to observe distant objects, very interesting and practical scientific and technological inventions.
4, air-powered cart: use some balloons, carts and tape and other materials to make an air-powered cart. When you blow up the balloon and tie the mouth tightly, the balloon will expand and generate thrust to push the cart forward.
The Importance of Science and Technology:
1. Promoting Social Progress: The development of science and technology promotes social progress and improves people's quality of life. For example, the development of modern medical technology makes people's life expectancy can be extended, the development of transportation technology makes people can be faster and more convenient to reach their destinations, the development of information technology makes people can obtain and transfer information in a more efficient and accurate way.
2, promote economic growth: the development of science and technology for the contribution of economic growth can not be ignored. Scientific and technological innovation can bring about more efficient and lower-cost production methods, improve production efficiency and product quality, thereby promoting sustained economic growth.
3. Improvement of human life: the development of science and technology provides people with more convenience and comfort. For example, the development of smart home technology can make it easier for people to manage their family life, the development of medical technology can provide more efficient and accurate medical services, and the development of Internet technology can make it easier for people to access information and communication.
