Encountering the Idea

The teacher goes behind a desk or tall bookcase so the students cannot see what she is doing. She rings a bell and asks the students to guess what she did. She repeats this with various objects that students cannot identify. She then writes a note on a piece of paper, and again, asks what she did. The students say they don't know because they can't see or hear. What sense were you using before? Hearing. Without hearing it is hard to learn about the world. We would have to use another sense.

What causes sound? You have to hit something? Is that the only way? You can talk. What else? These are the questions we are going to investigate in the centers, today, but before going to the learning centers, we are going to have group play.

  1. The teacher claps her hands, taps her foot, rings a bell, etc., a certain number of times. The students count and tell how many times they heard a sound.
  2. A child creates a pattern with different sounds (clapping, snapping his/her fingers, dramatic sound effects, high or low voices, loud or soft voices, musical instruments, stamping feet, etc.). Students repeat the patterns and create their own.

Tell students that sounds help us identify things. In one of the activities, students will try to identify sounds. They will then select their favorite sound and graph the information.


Exploring the Idea

At the Science Center, the students

Students do the following:

  1. Each pair of students receives two yogurt containers and a length of string.
  2. The students make a hole in the bottom of each container with a pencil.
  3. The students thread the ends of the string through the holes in the containers from the outside in, making a knot at each end of the string to keep the string ends from slipping out of the holes.
  4. One partner stands at one end of the classroom while the other partner moves as far away as needed to make the string taut.
  5. Each partner takes a turn speaking into the "phone" while the other listens at the other end. Keep the string taut.

At the Mathematics Center:

  • The teacher prepares several sealed containers holding one object or a combination of several different objects. Students shake the containers and describe the sounds they hear. They predict what's inside. They record their predictions and then open the containers and compare predictions with actual results.
  • Students shake several sealed containers and predict what's inside. They then try to find and match one container with another that has the same objects inside.
  • Students take turns wearing blindfolds and listening to a partner drop beans on the table. One player drops one then two beans in succession, for example: drop ... drop drop. The blindfolded student says three - why? One plus two or one plus one plus one. The students use different sound patterns through five.

At the Listening Center, students listen to a prepared tape of various sounds and then guess what objects made the sounds, by matching sounds to picture cards. Then they sort the picture cards of sounds by soft and loud. Students listen to the sounds and arrange the pictures in the order in which they heard them.

At the Music Center the students identify the deepest, highest, loudest and softest sound in the taped sounds.

At the Writing Center, children wear earplugs to experience being hearing-impaired. Discuss and record emotions they felt on a language chart or individual sheets that can be compiled into a class book. The students discuss lip reading and sign language.


Getting the Idea

1. Read the book Hearing. The students discuss hearing as one of the five senses that we use to learn about the world we live in. They discuss the things they heard on their outdoor walks. Were all the sounds they heard pleasant? Was there noise? Music? Did they hear laughter? Crying? What did they learn about the world through the sense of hearing? Students make suggestions that are written on a chart to be used later in the Writing Center.

2. After discussing with the students the activity with the paper "phones", ask for suggestions as to how they work. After the students have given their ideas, explain that when the talking partner speaks, the air in the container vibrates. The string carries the vibrations to the container at the other end, and the listening partner hears them as sounds.

3. What makes the sounds that our ears pick up? (Vibrations that travel in the air.) Things need to vibrate before we can hear them. Did the paper phones vibrate? The rubber band? Your throat?

4. As you show a diagram of the external and internal ear, describe how the ears work. Play the tape recording of one of the sounds, or play a radio. Ask the students to place their hands on the radio to feel the vibrations. Tell them we can hear the music or the voice coming from the radio or tape player because it is vibrating - it is making the air vibrate or move back and forth. As the air moves back and forth, or vibrates, it makes sound waves. The sound waves travel through the air in all directions. The waves reach the outer ear and travel through the ear canal. As they travel in the ear canal, they strike the eardrum, and make it begin to vibrate. These vibrations make other parts of the ear, called the middle ear, vibrate.

As the middle ear begins to vibrate, a small part in the inner ear, called the cochlea, begins to vibrate. The cochlea is a small bone shaped like a seashell that is filled with liquid. As the shell, or cochlea, begins to vibrate it makes the liquid inside it vibrate. The vibrations of the liquid tickle tiny hairs that line the cochlea, causing them to vibrate and send a message to the auditory nerve. This nerve also acts like an electrical wire and sends the message to your brain. Remember, all of this has to do with vibrations.

When the brain receives the sound message, again it figures out what the sound is, what is making the sound (the vibrations from the radio) and what you should do about it (enjoy it if it is your favorite group). In the morning if you hear your mother telling you to get up to go to school, you get up and hurry.

Your ears do more than just hear sounds - they help us keep our balance. The inner ear helps us know if we are sitting, standing, lying down, or hanging upside down! You know also that you can make yourself very dizzy and even sick to your stomach by spinning yourself around for a long time.

Sounds can also help us get away from danger. Ask the students to describe the process that they follow when there is a fire drill. What warns us of danger?

5. Ask students why they think that the class favorite sound was __________ in the survey. After their explanations, ask them if all the sounds they hear are pleasant? unpleasant? What does their sense of hearing tell them about sounds?

6. What else does our sense of hearing do for us? (It warns us of danger.)


Organizing the Idea

1. Students study a sign language chart and pick out three words that they learn to sign. They show what they have learned to the class.

2. Working in pairs, students practice lip reading from each other. They decide on a message first and say it without sound, and the partner reads the lips.

3. Discuss with the students the proper care of ears. They make posters for hall display indicating proper ear care and safety. At the Writing Center, students dictate sentences listing what you should do and should not do to your ears.


Applying the Idea

Invite a piano tuner to demonstrate to the class how the sense of hearing helps him or her perform the job. What kind of training does it take to become a piano tuner?

Invite a police officer, fire fighter or soldier to tell the class what the hearing requirements are for the type of work he or she does. Why is the sense of hearing important for each one of these jobs?


Closure and Assessment

Oral Assessment
  1. How do we communicate with each other?
  2. What part of you body do you use to hear?
  3. Could you communicate if you couldn't hear? How?
  4. How would you feel if you couldn't hear? Why?
  5. Why and how do you have to take care of your ears?

Performance Assessment
Put pictures of objects in a box. Students sort them by things they can hear (that make noise) and things they can't hear (don't make noise).

Written Assessment
Given labels for ear parts and a diagram of the ear, students place labels on a ear diagram.
