5. Thursday, December 1st
Entry Task Why is this scout doing this? Use what you know about the speed of sound in different mediums in your answer.
Schedule:
16.1 Sound is a wave
Objective: I will explore how sound travels through a medium
Homework:
Activity questions if not finished in class
Please have on desk:
ISN open to 16.1 notes and RSG, entry task brochure

6. Do you know……
What is necessary for sound waves to be produced by an object?(518 and/or 520)
How sound waves travels from one place to another?(520)
How sound waves are detected by humans?(519)
How the type and temp. of medium affects the speed of sound waves?( )

7. Sound waves are a result of Vibrations

8. Sound is a mechanical wave – it needs matter to travel through
Sound can travel through solids, liquids and gases
Sound CAN’T travel through a vacuum (area with no/few particles)

11. Sound waves are detected by the ear. The ear has 3 regions:
Outer Ear – Gathers and funnels the sound wave
Middle Ear – Transfers the vibrations
Inner Ear – Converts vibrations to electrical signals

12. Sound travels fastest in solids
Particles are closer together in solids
Particles don’t have too far to travel to transfer their energy

13. Sound travels faster in warmer materials.
Particles are moving faster in warmer materials
Particles have more energy to transfer

14. Friday, December 2nd
Entry Task Can sound travel through all states of matter (solid, liquid, gas)? Provide evidence to support your answer.
Schedule:
Intro to Frequency and Pitch
Objective: I will explain how the frequency of a wave is related to the pitch of a sound
Homework
16.2 RSG

ISN and entry task brochure

15. Every Sound is a Present Write each question in comp. book
What is the purpose of a cochlear implant?
What is the energy transfer that occurs in an ear when we hear?
What is the purpose of the microphone on the external portion of the cochlear implant?
Will the sounds Kelly hears be like the sounds detected by a person with normal hearing? Explain

16. Every Sound is a Present
A cochlear implant allows people with damaged a cochlea to hear. Takes the place of hair cells that are missing.
Sound energy is turned into electrical energy inside the normal ear.
The microphone picks up the sounds from outside the ear and transmits them to the computer
The sounds will not be the same because they are made by a computer with electrodes instead of a healthy cochlea.
