A fun and useful little DIY solar cell phone charger, the steps are as follows:
1. First of all, we need to repair the solar cell module. the upper solar panel. You can use a hot melt glue gun to stick the solar cell module to the solar panel. Be sure to maintain good contact between the solar panel and the battery module.
2. Connect one end of the USB data cable to the positive pole of the solar cell module (usually a white or brown plug) and the other end to the output port of a cell phone power bank or mobile power supply.
3. Insert the cell phone power bank or mobile power into the power socket and turn on the switch. At this point, if everything is working properly, the solar panels should start absorbing sunlight and converting it into electricity. After havingobserved for a while, if the solar panel starts to heat up, it means it is working.
4. When you need to charge your phone, simply connect the phone to the USB data cable. Since the solar panels have stored some of the energy, the phone can still get a certain amount of energy even on cloudy days or at night.
A fun and useful little craft can be used to make a simple weather instrument. The production steps are as follows:
1. make a small hole in the bottom of the bottle to pass the wires through. Use scissors and pliers to gently open the bottom, then use pliers to fold the edges inward to create a small opening. Next, use a needle or small tool to make a small hole in the opening so the thread can pass through.
2. After passing the thread through the mouthsize, attach it to the side of the bottle. You can use double-sided tape to attach the wire to the bottle, or you can use a screwdriver to secure the wire to the edge of the bottle.
3. Next we need to make a simple weather vane. First, cut out four equal-sized triangles from pieces of colored paper or plastic wrap. Next, align one side of the triangle with the side of the other triangle and stick them together with double-sided tape.
4. On the other side of the marker, cut a long, thin line along its edge to serve as the arrow for the weather vane. Attach the weather vane to the top of the bottle, you can use double-sided tape to stick it to the top of the clear plastic bottle.
5. Finally, we need to create a simple water level gauge. First, choose two beads of similar size from silicone beads or pebbles. PlPlace them in two clear plastic cups and add enough water to completely submerge them.
6. Connect the bottoms of the two cups with copper wire to form a simple pipe. You can use scissors to cut both ends of the copper wire to the appropriate length and then connect them with pliers. Insert the battery box into the other end of the wire and connect the connector between the wire and the battery box. Make sure the battery compartment is oriented correctly, with the positive terminal facing up.
Handmade elementary school on technology
Easiest way to createManual steps for satellite model:
1. We need to prepare some materials, such as cardboard, double-sided tape, scissors, colored pens, etc. Then we can draw a square on the cardboard and cut it out. This square will serve as the body prmain to the satellite.
2. We need to use colored pens to color the main body of the satellite and mark various parts of the satellite, such as solar panels, antennas, etc. This can help us better understand the structure of satellites.
3. We need to use double-sided tape to attach a thin piece of cardboard to the bottom of the satellite body. This thin piece of cardboard will serve as a support for the satellite and help us place the satellite model on the table.
4. We can install a small reflector on top of the satellite model to act as a “solar panel” for the satellite. When we place the model in the sun, the reflective sheets reflect sunlight, allowing us to better understand how the satellite works with solar energy.
5. Creating the simplest satellite model by hand can not only help us understand the basic structureand the operating principles of satellites, but also exercise our practical abilities and creativity.
Notes on creating satellite models manually:
1. Choose suitable materials: Choose cardboard with hard texture and not easy to deform as the main material. adhesives such as double-sided tape that are easy to apply and attach.
2. Carefully draw and label the different parts of the satellite: When coloring and labeling the different parts of the satellite, draw carefully to ensure that the proportions of each part are coordinated and the labels are clear. This provides a better understanding of how satellites are built and operate.
3. Keep clean: During the production process, be sure to keep your hands and tools clean to avoid dust, impurities, etc. do not contaminate the satellite modelite.
4. Pay attention to the safe use of scissors and other tools: When using scissors and other tools, pay attention to safety and avoid cutting or scratching your hands or other parts.
5. Respect and protect the environment: After use, be sure to put the waste in the trash can and keep the environment clean and tidy. We must also pay attention to the protection of our earth environment.
6. Practice and exploration: After production is completed, you can put the satellite model in the sun for practice and exploration, and observe whether the solar panels can work normally.
The content of the elementary craft school on technology is as follows:
1 Make simple circuits : you can use. batteries, light bulbs, copper Make simple circuits using wires, etc., and observe theoperating principles and circuit phenomena.
2. Make a simple robot: You can use scrap materials like cardboard, iron boxes, electronic components, etc. to assemble a simple robot to learn the basic principles and skills of robot assembly.
3. Build a magnetic device: You can use strong magnets and small metal blocks to combine various interesting magnetic toys or devices to deepen your understanding of magnetism.knowledge.
4. Make a simple windmill: You can use materials like cardboard, plastic, toothpicks, etc. to make a simple windmill and understand the principle of converting wind energy into electrical energy and other forms.
5. Create a simple solar powered device: You can use solar panels to collect solar energy and create an apsame as simple solar energy to understand the concept and application of solar energy.
6. Make a super crystal ball: You can use a mixture of boric acid, lye, and hot water, pour it into a small plastic ball, and after a few days you will be able to see beautiful crystals growing. in the ball.
What are the benefits of doing tech crafting?
1. Cultivate interest in science
Small science experiments can help primary school students understand the mystery and charm of science, thereby stimulating their interest in science. Curiosity and interest. Through experiments, they can personally experience the laws of nature and scientific principles, and develop a strong interest in scientific knowledge. For example, by conducting wilt recovery experiments, primary school students can obspersonally observe the leaf recovery process and understand the physiological characteristics of plants.
2. Promote cognitive abilities
Through scientific experiments, primary school students can explore natural phenomena and scientific principles, thus promoting the development of their cognitive abilities. The experimental process requires them to observe, record and analyze data, and to develop their observation, analysis and reasoning skills. For example, in gas expansion experiments, primary school students can observe the changes of gas expansion and understand the properties and characteristics of gases, thereby promoting their cognitive abilities.
3. Develop experimental skills
Small science experiments can help elementary school students learn basic experimental skills, tthey weigh, mix, pour, etc. These experimental skills can develop primary school students' observation, thoroughness and experimental skills, and also lay the foundation for them to learn more complex science experiments in the future.
