1. Fruit generator: Use lemons, apples, oranges and other fruits to generate electricity and learn the principles of power generation.
2. Paper cup microphone: Use materials such as paper cups and earphone wires to make a simple microphone and understand the principle of signal transmission.
3. Simple wind turbine: Use small fans, magnets, coils and other materials to learn the principles of wind power generation.
4. Simple telescope: Use two magnifying lenses and tape and other materials to learn the principles and production methods of telescopes.
5. Simple solar water heater: Use black plastic bags, transparent plastic bags, aluminum foil and other materials to learn the working principle of solar water heaters.
1. First, you must synthesize a wind kinetic energy generator;
2. After the wind kinetic energy generator is made, you must choose a place with relatively strong wind. To put it down, you can use an anemometer to find it, or you can just build a high platform and put the machine down after you find it;
3. After putting it down, you need to make one thing, which is the rotor. There are four rotors in it. The types of rotors are wooden rotors, iron rotors, steel rotors, and carbon rotors. The wooden rotor is used as a demonstration here;
4. After the rotor is ready, click on the wind kinetic energy generator, and then put the rotor on Go inside, and then the rotor will spin. If it doesn't spin, it means there is insufficient wind or something is blocking it;
5. After the above steps are completed, you need to make a kinetic energy generator. Machine, because the wind kinetic energy generator only provides power and does not produce electricity, it needs a kinetic energy generator to generate electricity;
6. After it is done, place it behind the wind kinetic energy generator, put it down and open it , you will see that the kinetic energy generator is continuously generating electricity;
