| Sound is a form of energy we hear with our ears and is a part of everyday life. Sound makes matter vibrate and that causes sounds. Sound waves enter our ears and causes the eardrum to vibrate which sends a message to our brain as to what the sound is. Vibrations are caused when when objects move back and forth very quickly. If you place your hand on your throat and hum you will feel vibrations. Sounds can be loud or soft and high and low. Sound can be absorbed or reflected. Read the info on this sheet and then answer the questions. Explain what sound is and how it happens. Why do you think you can hear better in air than underwater? |
