1, steamboat model: A simple steamboat model can be made by using some discarded materials, such as plastic bottles, cardboard and glue. Firstly, plastic bottles are used as the hull, then cardboard is used as the paddle and rudder, and finally steam is generated by heating water to push the steam boat forward.
2. Small generator: A simple small generator can be made with some copper wires, magnets and magnetic coils. The copper wire is wound on the magnetic coil and then placed on the magnet. When the magnetic coil rotates, it will generate current, thus realizing power generation.
3. Solar panel model: With some small solar panels and LED lights, you can make a stupid solar power generation system model by making a simple sketch. Connect the solar panel to the LED lamp. When the sunlight hits the solar panel, the LED lamp will light up.
4. Paper airplane design: Making paper airplanes is a simple and interesting small-scale technical production project. You can design different types of paper airplanes with a piece of paper according to a specific folding method. Try different button designs and adjustments to see which one can fly farther or more stably.
5. Water rocket experiment: You can make a simple water rocket with some discarded plastic bottles and compressed air. Pour some water into the plastic bottle, then quickly turn the plastic bottle upside down and put it on the ground. Using a pump or compressed air tank to inject compressed air into the bottle, when the pressure accumulates to a certain extent, the water rocket will be ejected at high speed.
Skills of making handicrafts by science and technology;
1. Planning and preparation: Make sure you have a clear plan before you start making it. Determine the project you want to do and list the materials and tools you need. This can avoid accidents or interruptions in the production process.
2. Safety first: always put safety first in any experiment or production process. Make sure you understand the potential risks of the materials and tools used and take appropriate protective measures, such as wearing gloves and goggles.
3. Careful and precise: Technical production usually requires some precise measurement and assembly. When making any cutting, welding or connection, make sure to measure carefully and use appropriate tools to ensure accuracy.
4. Try and adjust: Technical production is a process of constant trial and adjustment. Don't be discouraged if your project doesn't work or the effect is not satisfactory. Try different methods and adjust parameters to find the best solution.
5. Recording and reflection: In the production process, remember to record the results of each step and experiment. This will help you better understand and review your experiments and make improvements in future production.
