1. Choose a suitable piece of paper and cut it into a square. Then, fold the square paper diagonally in half to form a crease. Then, fold the four corners of the paper inward along the crease to form a small square. Then, each corner of the small square is folded outward to form the blades of the windmill.
2. You need to make a windmill bracket. Choose a bamboo stick, sharpen one end, then bend it into a small circle and fix it in the center of the blade.
3. Fix the leaves on the bamboo stick with glue. Pay attention to ensure that the blades are arranged in the correct order and direction.
4. After the production is completed, you can put the windmill in a windy place, such as window sill, doorway or outdoor. When the wind blows, the windmill will rotate, bringing happiness and beauty.
A windmill is a mechanical device, which uses the energy generated by a wind-driven wheel with adjustable blades or rungs to run. Usually used for power generation, irrigation, drainage, ship propulsion, grinding, refrigeration and so on. Because it can convert kinetic energy of wind into mechanical energy, it is widely used in various fields.
Advantages of making windmills:
1, cultivate creativity: it takes some creativity and imagination to make windmills. By using different materials and designs, everyone can make a unique windmill. This process can help people develop creativity and manual skills.
2. Enhance patience and attention: It takes patience and attention to make windmills. You need to carefully fold and paste the paper to ensure that every part of the windmill is assembled correctly. This process can help people to improve their patience and attention, and complete tasks more intently.
3. Understand the principle of wind energy: A windmill is a mechanical device driven by wind energy. By making windmills, you can understand the working principle and conversion process of wind energy. This will help you better understand the application and transformation of natural energy.
4. Increase the fun of learning and exploring: Making windmills is not only a way of entertainment, but also can increase the fun of learning and exploring. You can learn about the use and mechanical principle of origami and glue by making windmills. At the same time, we can also explore the application of windmills in different fields, such as power generation, agriculture and aquatic products.
5. Environmental protection and sustainable development: Windmills are made of renewable materials, such as paper and bamboo poles. Compared with buying ready-made products, DIY is more environmentally friendly and sustainable. In addition, by making windmills, you can reduce your dependence on non-renewable resources such as plastics and make contributions to environmental protection.
