音量与振动
Volume & Vibrations
发现声音的强弱与产生声音的振动强度之间的规律
Find patterns between the volume of a sound and the strength of the vibrations that produced it
学习证据 / Evidence
- 描述规律:更强的振动(更大的运动)产生更响的声音
- 通过改变施加在发声物体上的力来展示音量的变化
- 解释音量是声音的响或轻,由振动的大小决定
- Describe the pattern: stronger vibrations (larger movements) produce louder sounds
- Demonstrate volume changes by varying the force applied to a sound-making object
- Explain volume as how loud or quiet a sound is, determined by the size of vibrations
