Sound and Hearing

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.

I Corinthians 12:17-18 Psalm 139:14

If the whole body were an eye, where would be the sense of hearing? If the whole body were an ear, where would be the sense of smell? But as it is, God arranged the members in the body, each one of them, as he chose.

I praise you, for I am fearfully and wonderfully made. Wonderful are your works; my soul knows it very well.

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

And God blessed them. And God said to them, "Be fruitful and multiply and fill the earth and subdue it and have dominion over the fish of the sea and over the birds of the heavens and over every living thing that moves on the earth."

Now out of the ground the LORD God had formed every beast of the field and every bird of the heavens and brought them to the man to see what he would call them. And whatever the man called every living creature, that was its name.

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

what is man that you are mindful of him, and the son of man that you care for him? Yet you have made him a little lower than the heavenly beings and crowned him with glory and honor. You have given him dominion over the works of your hands; you have put all things under his feet,

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

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

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.

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

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.

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

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.

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

Sound Wave Demonstration

How does sound travel through air?

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

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

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

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 reasonMatt.10:27 why we turn our ear in the direction of sound when we want to hear something (Prov. 2:2).Prov. 2:2

What I tell you in the dark, say in the light, and what you hear whispered, proclaim on the housetops.

making your ear attentive to wisdom and inclining your heart to understanding;

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.

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

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

You shall not curse the deaf or put a stumbling block before the blind, but you shall fear your God: I am the LORD.

I was eyes to the blind and feet to the lame.

And when he returned to Capernaum after some days, it was reported that he was at home. And many were gathered together, so that there was no more room, not even at the door. And he was preaching the word to them. And they came, bringing to him a paralytic carried by four men. And when they could not get near him because of the crowd, they removed the roof above him, and when they had made an opening, they let down the bed on which the paralytic lay.

And when Jesus saw their faith, he said to the paralytic, "Son, your sins are forgiven." Now some of the scribes were sitting there, questioning in their hearts, "Why does this man speak like that? He is blaspheming! Who can forgive sins but God alone?" And immediately Jesus, perceiving in his spirit that they thus questioned within themselves, said to them, "Why do you question these things in your hearts?

Which is easier, to say to the paralytic, 'Your sins are forgiven,' or to say, 'Rise, take up your bed and walk. But that you may know that the Son of Man has authority on earth to forgive sins"--he said to the paralytic-- "I say to you, rise, pick up your bed, and go home." And he rose and immediately picked up his bed and went out before them all, so that they were all amazed and glorified God, saying, "We never saw anything like this!"

And they brought to him a man who was deaf and had a speech impediment, and they begged him to lay his hand on him. And taking him aside from the crowd privately, he put his fingers into his ears, and after spitting touched his tongue. And looking up to heaven, he sighed and said to him, "Ephphatha," that is, "Be opened." And his ears were opened, his tongue was released, and he spoke plainly.

And Jesus charged them to tell no one. But the more he charged them, the more zealously they proclaimed it. And they were astonished beyond measure, saying, "He has done all things well. He even makes the deaf hear and the mute speak."

And they came to Jericho. And as he was leaving Jericho with his disciples and a great crowd, Bartimaeus, a blind beggar, the son of Timaeus, was sitting by the roadside. And when he heard that it was Jesus of Nazareth, he began to cry out and say, "Jesus, Son of David, have mercy on me!" And many rebuked him, telling him to be silent. But he cried out all the more, "Son of David, have mercy on me!" And Jesus stopped and said, "Call him." And they called the blind man, saying to him, "Take heart. Get up; he is calling you."

And throwing off his cloak, he sprang up and came to Jesus. And Jesus said to him, "What do you want me to do for you?" And the blind man said to him, "Rabbi, let me recover my sight." And Jesus said to him, "Go your way; your faith has made you well." And immediately he recovered his sight and followed him on the way.

Now Peter and John were going up to the temple at the hour of prayer, the ninth hour. And a man lame from birth was being carried, whom they laid daily at the gate of the temple that is called the Beautiful Gate to ask alms of those entering the temple. Seeing Peter and John about to go into the temple, he asked to receive alms. And Peter directed his gaze at him, as did John, and said, "Look at us." And he fixed his attention on them, expecting to receive something from them.

But Peter said, "I have no silver and gold, but what I do have I give to you. In the name of Jesus Christ of Nazareth, rise up and walk!" And he took him by the right hand and raised him up, and immediately his feet and ankles were made strong. And leaping up he stood and began to walk, and entered the temple with them, walking and leaping and praising God. And all the people saw him walking and praising God, and recognized him as the one who sat at the Beautiful Gate of the temple, asking for alms. And they were filled with wonder and amazement at what had happened to him.

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

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.
