Scientific Enlightenment:

Solar cars are vehicles that are driven by solar energy. Compared to traditional cars powered by heat engines, solar cars are truly zero-emission. Due to their environmental benefits, solar cars are promoted by many, and the development of the solar car industry is growing rapidly.

Science Project:

1. Recognize and prepare the necessary materials for the experiment.
Step 2: Install according to the instructions in the manual.
3, Install and debugging.

Scientific Principles:

The energy of sunlight is converted into current through solar panels, which then flows through the motor, causing it to rotate, generating mechanical energy, thereby spinning the wheels, propelling the car forward. Solar panels do not store solar energy; they convert it into current in real time. When there is no sunlight, the car will stop, and at that point, batteries can be used as a power source to supply electricity.

Science Expansion:

In a sense, solar cars are also a type of electric vehicles, the difference being that electric vehicles charge their batteries from industrial power grids, while solar cars use solar cells. Solar cars convert sunlight into electricity using solar cells, which are then stored in batteries for later use to power the car's electric motor. Since solar cars do not burn fossil fuels, they do not emit harmful substances. It is estimated that if solar cars replace traditional gasoline-powered vehicles, each car's carbon dioxide emissions could be reduced by 43 to 54%.
The device on the solar-powered car, which is densely packed like a honeycomb, is the solar battery board. Solar batteries are usually divided into silicon batteries, cadmium sulfide batteries, gallium arsenide batteries, etc., of which the most commonly used is the silicon solar battery. Under the sun, the solar photovoltaic battery board collects sunlight and generates the current that people are familiar with. This energy is stored in the battery for future travel. It can also be directly supplied to the engine to charge while driving. The energy drives the wheels through the engine controller, pushing the solar-powered car forward. Moreover, without an internal combustion engine, solar electric cars do not have the roar of the fuel cars when driving.

Scientific Exploration:

1. What scientific facts have you learned by making a solar-powered wooden car?
What is the principle of the solar-powered wooden car?
3, What other principles are similar in life?

  Before assembling, please check if the circuit is unblocked and all the components are complete. Ensure that all contact points are in good contact. During the assembly process, be careful not to get glue on your clothes or skin. Keep the parts out of reach of younger siblings to prevent them from swallowing them by mistake! Do not play with them on your head, to avoid the model falling and injuring you!
