Sound Science Test
5th grade, science, sound
| Question | Answer |
|---|---|
| Sound Discrimination | Identifying sound from one another. |
| Properties | An object's look feel,sound,taste,and smell are its properties. |
| Code | Signals used to represent letters and numbers. |
| Vibration | A shaking,back-and-forth movement. |
| Sound reciever | something that detects,responds to,or hears a sound. |
| volume | How loud a sound is. |
| Pitch | Describes how high or low a sound is. |
| Frequency | A fast vibration produces a high frequency. |
| Tension | Force applied to an object trying to pull it apart. |
| Stethoscope | Device used by a doctor to amplify sound. |
| Amplify | To make louder |
| Megaphone | Collects and focuses sound energy to amplify it at the source or receiver. |
| Drop chamber | objects can be identified their properties, including the sound they make. sounds can be discriminated by their characteristics |
| drop codes | sounds can convey information to humans in codes, ie, warnining signs |
| tone generator/tuning fork/long gong | all sounds come from a source that is vibrating anything that detects a sound is called A SOUND RECIEVER, I.E. ea, telephone, reciever, microphone stronger, more intense vibrations make a louder sound |
| tounge depressor | fast vibrations produce high pitched sounds. slow vibrations produce low pitched sounds. |
| water phone/ xylophone/ kalimba/ string beam | a long object has a low pitched and vibrates slowly. a short object has a high pitch and vibrates quickly. |
| the mini gutbucket/ the foss-ulele (tension) | the greater the tension on a sound source, the higher the sound. |
| sounds through air and water | sound can travel through water. sounds travel faster through aliquid (water) vs. a gas (air). therefore sounds are louder in a liquid vs. a gas. |
| sounds through solids; wood and string | sounds travel well through solids like wood and string.sounds travel best through solids- fast,loud,clear. for sound to exist there must be a sound source,a medium or form of matter for sound to travel through,and a receiver. |
| sound through solids- continued | all three elements must exist for sound to exist. sound energy can be amplified with a megaphone at the sound source or sound receiver. |
