To be successful you; Describe these sound waves: Must: use the term vibration to describe how sounds are produced Should: describe volume or pitch by looking at a sound wave Could: explain why sound travels faster in solids and liquids than gases How are sounds produced? This sound is getting Eg. quieter I can tell because the height of the wave is smaller Is human hearing better or worse This sound is getting than an animal’s? ______________ I can tell because ________________________ ` This sound is getting ________and ______ I can tell because ________________________ Key Words: sound wave higher pitched This sound is getting vibration louder quieter particles lower pitched amplitude frequency ________and______ I can tell because _____________________ Why do sound travels faster in solids and liquids than in gases? Give examples to help explain your answer. Finish this sound wave A B C D E F Make the following changes at Describe how you think sound recognition How does human hearing differ to that of the specific point technology might work. animals? A – Increase the volume B – Increase the frequency C – Decrease the amplitude D – Decrease the pitch E – Increase the amplitude F – Decrease the pitch
