Electric Shooting Experiment

Electric Shooting Experiment consists of a photoelectric control circuit composed of a photoelectric receiving tube and a laser light-emitting tube. When the photoelectric receiving tube receives a strong infrared laser, it is sent to the main control circuit U1 for processing, and then output to the horn to read out the voice of the laser gun hitting the receiving tube. Understand the principle and application of optical switch through experiment.

Diy Steam Engine

Diy Steam Engine uses alcohol lamp to heat the water in the closed space. When the water is heated and vaporized into water vapor, the volume expands at the same time, generating air pressure to push the piston to move, generating mechanical energy, giving the flywheel an initial speed, pushing the piston to move back and forth, and driving the motor to generate electricity through gears. Understand the basic principle and application of steam engine through experiments.

Electric Bell Experiment

Electric Bell Experiment uses the magnetism produced when the electromagnetic current passes through to draw the shrapnel under the small hammer to strike the bell. At the same time, the circuit is disconnected, the electromagnet loses its magnetism, the small hammer is bounced back again, the circuit is closed and repeated, and then a continuous hitting sound is produced. Understand the working principle and application of electromagnet through experiment.

Motor Experiment

Motor Experiment uses the electromagnetic induction principle that the electrified coil moves in the magnetic field to make the motor model. The electrified coil is the enameled wire wound on the silicon optical sheet, which has three groups in total. The electrified coil rotates under the force in the magnetic field. Through experiments, we know that electric energy can be converted into kinetic energy.

Funny Game Of Electric Conduction

Funny game of electric conduction is composed of modeling conductive metal, LED lamp and buzzer. When the metal hook of the electric shock rod contacts with the conductive metal wire, the whole circuit forms a path, the buzzer will ring, the LED lamp will be on, if not, the circuit will be open, and the whole circuit will not work. The hand eye coordination ability of children was developed through experiments.
