Sound
| Question | Answer |
|---|---|
| What is sound? | a form of energy that travels in waves through matter |
| What is vibrate? | to move back and forth quickly |
| What are molecules? | particles in matter |
| What is a wave? | a change that carries energy from one place to another |
| How are sounds and waves related? | sound moves in waves through matter |
| What makes sound? | vibrations |
| What is a medium? | the matter through which a wave travels (solid, liquid, or gas) |
| What is pitch? | how high or low a sound is, and is caused by the frequency of the sound wave (High-frequency waves make the pitch high. Low-frequency waves make the pitch low.) |
| What is volume? | how loud or soft a sound is, the amplitude shows a sound wave's energy (If the amplitude is large, the volume will be loud. If the amplitude is small, the volume will be soft) |
| How do we measure a sound's volume? | decibels (softer sounds have lower decibels, louder sounds have higher decibels) |
| Sound travels the fastest through what medium? | solids (wood, metal...) |
| Sound travels the slowest through what medium? | Gases (air) |
| True or False? Something must first produce a vibration before it can produce a sound. | True |
| How do you make the volume louder when hitting a drum? | Hit the drum harder |
| How did you change the pitch when you made the ruler and rubber band instrument? | Stretch the rubber more or less tightly |
