Sound producing experiment tools for the elementary and middle school students

摘要

This design is second. Resonance and sound generators for secondary students.;In the physics experiments of elementary and secondary students, it is possible to generate sound by using a long cylindrical conduit for easy understanding of vibration and resonance, or to control the height of the resonance sound by containing a liquid such as water. Observing the state of change These experimental devices or instruments are second. Secondary students end up with simple experiments and are not interested enough to satisfy the learning effects of voluntary participation. In particular, once the interest is lost due to the characteristics of the physics subject, it becomes difficult to achieve further learning effects, which gives a sense of skepticism about the science subject itself.;The present invention is a hollow cylindrical body, the lid of the thin plate structure to generate a vibration sound by covering the inclined opening on the upper end of the body, the resonance portion for adjusting the resonance sound generated by interpolating the body and the resonance portion Resonance and sound generation experiment device composed of supporting handle was developed to directly experience vibration and resonance phenomenon. As a result, the physical phenomena of sound such as resonance and vibration were easily understood and the motivation to participate was maximized to maximize the effect of physical science education.
