Science
Thursday, November
Focus: parts of the ear
& vocal cords

2. Warm Up.. Place your backpacks along the back wall
Grab your notebook, pencil, agenda
Complete Thursday’s warm up now! DO NOT WORK AHEAD!
REMEMBER YOU ARE QUIET IN YOUR SEAT WORKING WHEN THE FINAL BELL RINGS

3. Agenda… Finish up Tuning Fork Lab with discussion and demo.
KWL Chart in Notebook
Begin Parts of the Ear
guided notes
Color coding activity
Chromebook Activities

4. In your notebook…
Think back to our sound labs and explain how a tuning fork illustrates sound waves (explain in terms of sight, touch, and hearing)

5. In your notebook… In terms of sight:
When we looked closely at the tuning fork after hitting it on the table we could SEE VIBRATIONS
In terms of touch:
After hitting it on the table we could FEEL VIBRATIONS
In terms of hearing:
After hitting it on the table we could HEAR SOUND

6. K-W-L Chart – 5 minutes Draw this table in your notebook now…
“What I Know about Sounds”:
“What I Wonder about Sounds”:
“What I’ve Learned about Sounds”

7. K-W-L Chart- 3 minutes
Complete the column “What I Know about Sounds” (try to list 3 things in this column)
“What I Know about Sounds”:
“What I Wonder about Sounds”:
“What I’ve Learned about Sounds”

8. Guided Notes Handout You will now receive a worksheet (1/2 sheet)
These are guided notes for how sound travels to our ear and how it is picked up by our brains as sound
Follow along as we work to fill in the missing words

9. Sound in the Ear
The Outer Ear catches sound waves and funnels them into the ear canal where they strike the eardrum.

10. Sound in the Ear
The eardrum is a thin, taut (tight) membrane which vibrates as sound waves strike it.

11. Sound in the Ear
As the eardrum vibrates, it causes the tiniest bones in our bodies to move. These bones are known as the hammer, anvil, and stirrup.

12. Sound in the Ear
This movement amplifies, or increases, the sound. This region is known as the middle ear.

13. Sound in the Ear
These bones are attached to the cochlea, which changes vibrations to electrical impulses. The cochlea is a fluid-filled, snail shaped cavern in your skull behind each ear.

14. Sound in the Ear
Electrical Impulses are sent along the auditory nerve to the brain where it is interpreted as sound. This region is known as the inner ear. This is how we hear different sounds.

15. Fun Fact….
The inner ear also contains semicircular canals, which function more for purposes of equilibrium than hearing.
Do you know anyone that gets motion sickness?
This part of the ear controls how our mind feels balance!

16. How the ear works - animation

17. Color Coding Activity – Parts of the Ear
You will now receive a handout detailing the parts of the ear
We will work to color code our diagram of the ear now

18. Follow along as we color code the Diagram of the Ear

20. Chromebook Activities

27. Chromebooks…. I will dismiss you by rows to get your chromebooks
Once you are back at your seat, login
In a search box type StudyJams
Follow the directions on your handout
You have the rest of class to complete this !

28. Vocal Chords and Sound – write these notes in your notebook
Vocal chords produce sound.
Larynx = the voice box.
Trachea = windpipe (the tube that connects your lungs to your throat)
The vocal chords vibrate to create the sound of your voice. Put your hand on your throat and hum…you are feeling your vocal chords vibrate!

29. Vocal Chords

30. Animation for how vocal cords work

31. Exit Ticket…
You are a sound wave; describe the path you take to reach the brain!
