What are the primary school science experiment boxes?

In addition to conventional physical and chemical experiments, ancient instruments lost for thousands of years can also be "revived". Among them, the reporter saw strange utensils such as "Bibi" cup and "butterfly cup" have been lost in ancient China, so what are the primary school science experiment boxes?

What are the primary school science experiment boxes?

1. Primary school acoustic experiment box

The way of sound production and transmission will affect our lives, among which the size, height and timbre of sound are the key points. This product explores pleasant sound through the experimental equipment provided, so that students know that sound is generated by the vibration of objects and the pitch is high and low, the loudness of sound is related to the amplitude, and the transmission of sound needs medium.

Activity: vibration and sound experiments of objects; Tympanometer test; An experiment with sound levels; High and low pitch experiment; Tone perception experiment; The telephone experiment; Noise suppression experiment, etc.

Main configuration: human eardrum vibration demonstrator; Sound box; Tuning fork (256Hz, 128hz); Drums, gongs, cymbals, etc.

Packing: The box is made of ABS/PP injection molding, the outer size is 520*410*180mm.

2. Primary school optical experiment box

The product explains different optical principles through different optical experiments, including light composition, linear propagation and pinhole imaging; Understand the basic principle of glass refraction of light, explore the law of light refraction; Understand the basic structure and working principle of light scattering experiment; Understand the basic principle and imaging law of converging and diverging rays of convex and concave lenses.

Activities: Verification of light linear propagation experiment, light refraction experiment, etc.
