提出假说:声音可以通过气体(如空气)传播,也能通过固体、液体传播。声音的产生是因为声源的振动引起气体、液体或固体的振动形成声波传入人耳,使耳膜发生振动,产生了声音的感觉。实验材料:1.光滑的白纸(或小纸袋,如小纸药袋、薯条袋)2.剪刀、胶水3.小飞虫(或稍大一点的昆虫)
Propose a hypothesis: The sound can be transmitted through the gas (such as air), but also through the solid, liquid. The sound is generated because the vibration of the sound source causes the vibration of the gas, liquid or solid to form a sound wave which is transmitted to the human ear, causing the eardrum to vibrate and generate the feeling of sound. Experimental materials: 1. Smooth white paper (or small paper bag, such as small paper bag, French fries bag) 2. Scissors, glue 3. Small flying insects (or slightly larger insects)
