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. |
