Here is my work: a solar house.
1. Its production materials are: cardboard, transparent paper, cardboard and disposable chopsticks.
2. You also need to prepare production tools: scissors, double-sided tape and glue sticks.
3. When finished it will be a small house with beautiful glass windows and a fence around the house. Its roof is a solar absorption panel, which can absorb solar energy during the day and use the solar energy absorbed during the day to provide energy at night. There is no radiation, which is both high-tech and environmentally friendly.
4. It can improve people's physical and mental health, save resources, and make people feel warm. Our land is now in a state of destruction and tatters. So I hope that when we live in this type of solar house, we can redreduce the heavy use of resources and alleviate some of the burden on Mother Earth.
The function of the handmade solar small house is
The work of the science and technology festival is easy to do by hand
The simplest steps to make the simplest satellite model by hand:
1. We need to prepare 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 main body of 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 could help us better understand the structure of satellites.
3. We need to use double sided tape to attach a thin piece of cardboard to thelower body of the satellite. 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 structure and working 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 tapedouble sided easy to apply and fix.
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 model.
4. Pay attention to the safe use of scissors and other tools: When using scissors and other tools, pay attention to safety and avoidAvoid 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 and keep theClean and tidy environment. We must also pay attention to protecting our earthly 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.

A fun and useful little DIY can be used to DIY a solar cell phone charger. The steps are as follows:
1.First, the solar cell modules must be attached to the 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 observing for a while, if the solar panel starts to heat up, it means it is working.
4. When you need to chaTo connect 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 wire through the bottle, attach it to the side of the bottle. You can use double-sided tape to attach the wire to the bottle, or youcan 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, place one of the triangles Align one side of the other triangle and stick it 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. Place them in two clear plastic cups and add enough water to completely submerge them.
6. Connect the funds ofux 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.
