Primary school science and technology innovation laboratory configuration plan
The science and technology innovation laboratory consists of nine modules: electromagnetism, mechanics, optics, thermals, energy conversion, life sciences, mathematics and robotics. The design of experiments is carried out according to "fun", "suspicious", "moving" and "thinking". organization. Create a scientific inquiry experiment environment (experimental equipment, experimental methods, experimental atmosphere), follow the students' cognitive rules, and cultivate students' ideas, methods and abilities to solve practical problems. The Science and Technology Innovation Lab can meet the needs of students' independent learning. It solves the problem of how teachers teach and how students learn, which is conducive to students mastering research methods, mastering book knowledge, cultivating scientific inquiry ability and forming scientific values.

Specifications: 700 × 700 × 1000
Sound refers to a mechanical wave propagating in a medium with elasticity. It is derived from the vibration of the sounding body and belongs to the longitudinal wave. When sound is transmitted to the human ear, it causes the tympanic membrane to vibrate and stimulates the auditory nerve to make people feel the sound. The range of sounds that humans can hear is 20 Hz - 20,000 Hz. Usually, the three basic elements of sound intensity, tone and tone are physically described.

Light travels in a straight line in the same medium. But in fiber, light can travel along the curve. This is due to the fact that light forms a total reflection at the interface between the core of the fiber and the sheath. After countless total reflections, light passes through the curved fiber. The condition of total reflection is that light is emitted from the light-tight substance to the light-dissipating substance; the incident angle is greater than the critical angle. Here, the plexiglass is a light-tight substance; the air is a light-staining substance.
