  1. Sound and Hearing

  2. Lesson 8.1 God’s Design for the Human Body Objective: Students will identify the five senses and the body part associated with each. They will describe how God made people different from animals.

  3. I Corinthians 12:17-18Psalm 139:14

  4. Introductory Video

  5. 5 Senses Sight Hearing Taste Smell Touch

  6. God gave people the job of… …ruling over the animals Genesis 1:28 …naming the animals Genesis 2:19

  7. God gave people a special place in His creation.Psalm 8:4-6People have the ability to read, write, speak, and invent.

  8. Lesson 8.2 Ear Anatomy Objective: Students will identify and label the parts of the ear.

  9. The Ear Outer Ear The outer ear has 2 main parts: the external ear and the ear canal.

  10. The external ear is the part of the ear that we can see on the outside of the head. It helps the sound to enter the ear. The ear canal is a tube between the external ear and the eardrum. It guides the sound to the middle ear.

  11. Middle Ear The middle ear has 4 main parts: the eardrum, hammer, anvil, and stirrup.

  12. The eardrum is a tight surface like the top of a drum. It jiggles or vibrates when the sound reaches it. The hammer, anvil, and stirrup are the smallest bones in the body and start to jiggle along with the eardrum when sound reaches them.

  13. Inner Ear The inner ear has many parts including the semi-circular canals and the cochlea.

  14. The semi-circular canals are curved tubes. The cochlea is shaped like a snail shell. The auditory nerve carries the sound message to the brain. The brain understands the message.

  15. Lesson 8.3 Sound Waves Objective: Students will identify sound as energy. They will identify pitch and examine factors that determine high and low pitch.

  16. Sound Wave Demonstration

  17. How does sound travel through air?

  18. Vibrate To move back and forth Pitch The highness or lowness of sound

  19. Shorter object and faster vibration = higher pitch Longer object and slower vibration = lower pitch

  20. Lesson 8.4 Hearing Students will order the steps of hearing and identify the function of each part of the hearing process.

  21. The outer ear is shaped like a funnel that guides the sound wave into the ear. There is a reason why people whisper in your ear (Matt.10:27). There is a reason why we turn our ear in the direction of sound when we want to hear something (Prov. 2:2).

  22. Psalm 88:2 “May my prayer come before you; turn your ear to my cry.” The shape of the ear did not happen by accident. It is designed by a creative God. Psalm 139:13 For you created my inmost being; you knit me together in my mother’s womb.

  24. Lesson 8.5 Tech Connect: Hearing Students will recognize ways technology can help people with hearing loss.

  25. The Bible has a lot to say about people with disabilities including hearing loss. Leviticus 19:14 Job 29:15 Mark 2:1-12; 7:32-37; 10:46-52 Acts 3:1-10

  26. Understanding Deafness Video

  27. Lesson 8.6 Healthy Ears Students will explore ways of keeping their ears healthy and preventing hearing loss.

  28. Some simple things we can do to take care of our ears: *Have ears and hearing checked regularly. *Never put anything into your ear canal! A Q-tip can be used to clean the external ear. *If you have ear pain or something inside your ear, let your parents know right away. *Don’t listen to very loud music. This can damage your ears. *Wear ear protection around loud places.

  30. Yes or No The ear canal is part of the inner ear. No, the outer ear. A hearing aid helps make sound louder and moves sound into the ear. Yes.

  31. Sign language uses the hands and body to send a message rather than spoken words. Yes. The auditory nerve carries the sound message to the brain. Yes.

  32. Sound energy is produced when objects vibrate. Yes. The cochlea is part of the outer ear. No, the inner ear.

  33. The stirrup is part of the middle ear. Yes. When something vibrates it does not move. No, it does move back and forth.

  34. When a string vibrates really fast it has a low pitch. No, a high pitch. A long tube has a lower pitch than a short tube. Yes.

  35. There are only three senses – sight, smell, and taste. No, five senses – sight, smell, taste, touch, and hearing.
