Information related to teacher activities

The sound of the microphone is transmitted to the paper cup by the vibration of sound and air. The vibration of the paper cup is then transmitted to the straight line, and the vibration of the line is formed. The vibrating wire transmits the sound to the paper cup on the other side, and the vibrating paper cup transmits the sound to the ear.

Balloon microphone - after the sound is emitted, the vibration of the sound causes the vibration of the paper cup, and the vibration of the paper cup causes the balloon and the air inside the balloon to vibrate.

Spring microphone-spring can transmit 2 kinds of sounds. Because the spring is curved, the sound propagates slower when it bends than the sound emitted by the entire spring, so you will hear a sound like an echo. "Sounding Tube" Kindergarten Class Lesson Plan 2

< p> 4. When you are done, talk to one paper cup and put the other paper cup to your ear to listen

Activity process:

(1) Introduction to children's songs

< p>　1. "Telephone Call"

Two little dolls are making phone calls.

Hello, hey, hey? Where are you?

Alas! I'm in kindergarten!

2. Activities and Exploration

Children, we can hear all kinds of sounds every day. The teacher is talking now, and the children can hear it. Why is this? Because there are many air babies around us, sounds can be transmitted to children’s ears through the air babies.

How else can sound be transmitted? Think about it, if we are all fishing by the lake, and if a child is yelling at the lake, will we catch fish? No, the fish will be scared away. This is because the sound can also be heard by the fish through the water, and the small fish will be scared away. Next, ask the children to put their ears on the table and tap the table gently. We will hear a "dang-dang-dang" sound. Why is this? It turns out that when we knock on the table, the sound will be transmitted to our ears through the table. This is because the table is solid, and solids can also propagate sound.

Today we are going to make a microphone and show the finished product, just like the children in our children's song just made a phone call, and let the children observe the connection between the two cups. You can let two children try it. During the test, the wire of the microphone tube needs to be straightened. Why can I hear the other party speaking? Because the two cups are connected with a wire, the sound is transmitted to the other child's ear along the wire. This is because the wire is a solid, and solids can transmit sound.

(2) The activity is in progress

1. Material exploration

Show paper cups, thread and paper clips to let the children recall that we used cups and paper clips in the previous lesson What kind of treasure did you make online? Think about it, what will we use these things to do in this lesson? Let young children use their imagination.

2. Children explore freely. The teacher guides children to use a pricking needle to poke holes in the middle of two paper cups. Insert the two ends of the thread into the small holes in the bottom of the quilt and tie two paper clips to the thread respectively. At both ends of the paper cup, do not pull it off and then straighten or bend it to see if there is any change.

3. Summary: Sound propagates through three media, gas, solid, and liquid. The microphone transmits sound through wires. If the wires are not straightened, the sound will not be heard.

(3) Interactive Classroom: Children, which phone below has a clearer sound transmission? (Second)

(4) The teacher and the children summarize together, the teacher asks questions and evaluates the works

1. Summary: Sound is transmitted by the vibration of the medium, the one connected by the earth phone The wire vibrates whenever you speak. The curved wire cannot vibrate when speaking, so it cannot transmit sound.

2. Question: How much science do you know in the book?

3. Work exhibition review: Which microphone sounds the clearest?

(5) Summary and extension: Discuss why the sound is louder when the line is straight and louder when the line is bent

(6) Bring back the tearing pages, finished products, and bags

< p> Activity reflection:

Kindergarten science activities emphasize the process of children operating and perceiving things around them, constantly discovering problems and trying to solve them with the help of teachers' guidance and their own activities. . Let children independently explore the unknown based on what they already know, succeed through continuous attempts, and ultimately gain knowledge. "Mickey" Kindergarten Class Lesson Plan 4

Activity objectives

1. Know that the telephone was inspired by the invention of the microphone, and experience the fun of transmitting sounds.

2. Interested in scientific activities and willing to continue to explore the mystery of the microphone.

3. Let children experience the joy of success during activities.

4. Develop children’s observation and imagination.

Activity preparation

Paper cup microphone, tubes of different materials (hard tubes, soft sponge tubes), multimedia resources, research results display board, plastic tubes, cotton.

Activity process

1. Taking a visit to the "Sound Experience Hall" as the main line, playing with paper cup phones leads to activities to understand the transmission of sound.

1. The teacher asked: What is this? How to make the voice heard more clearly when playing with the paper cup phone?

2. Play the game of "whisper" in pairs. Then share and communicate what you just heard.

3. Teacher’s brief summary: Even small sounds can be heard, which shows that paper cup phones can transmit sounds. Let children learn the secrets of how paper cup phones transmit sound through this slideshow.

2. By playing with pipes of different materials, guide children to explore the relationship between sound transmission and materials.

1. The teacher guides the children to observe the differences of these tubes (color, soft and hard...) Can it transmit sound like a paper cup phone? Which tube transmits sound more clearly? Let the children discuss first guess.

2. Teacher: Present the results you think are in the form of sticky stars on the display board in front.

3. Work in pairs to use pipes of different materials to verify the results of the conjecture.

4. Share and exchange the research results, and then learn the secret of the sound absorption of soft sponge tubes by playing the slides.

3. The children were divided into three groups and used existing materials to freely assemble microphone tubes to understand how the sound would change if the combined shape of the tubes was changed or things were stuffed into the tubes.

1. Teacher asked: Can these tubes transmit sound? What will happen to the sound if the tubes are made very long? Can the sound still be heard if cotton is stuffed in the tubes? If Can you still hear the sound when the tube becomes curved? First guide the children to guess the result.

2. A group of four people try to change the shape of the tube or put something in the tube to explore what will happen to the sound.

3. Share and exchange the research results

Teacher’s summary: The sound becomes smaller as the tube becomes longer.

If the sound can still be heard when the tube is bent, it means that the sound will bend.

The sound became quieter after stuffing the cotton.

Extended activities:

Knowing that the telephone was invented based on the microphone, further explore what other things in life are made based on the principle of the microphone.

Teaching reflection:

In previous activities, I mainly entered and carried out activities as a guide and organizer, and I felt that I still had a certain connection with the children. distance. In today's activity, I tried to enter the activity as the children's playmate, play with the children, discover together, let the children feel that I am their big friend, thus further stimulating the children's interest in exploration, so that Children can ask questions boldly. "Megaphone" Kindergarten Class Lesson Plan 5

Design Intention

During an after-dinner area activity, two little girls used paper cups as small phones and imitated adults chatting. They only saw you. I was so happy every time I said it. The other children thought it was fun, and they also used the paper cups as small phones to play the game of making phone calls. Suddenly a child said: "It would be so fun if the paper cups could really be used as small phones to transmit sounds!" The children listened to this suggestion. I was excited and talked about the different opinions on "making a phone out of a paper cup". I immediately caught the child's interest and designed this scientific activity "Wonderful Microphone" based on the characteristics of the children in the upper class who are strong in hands-on skills and like to explore. . It is preset to focus on children's independent learning, and aims to guide children to acquire scientific knowledge through doing and playing through scientific exploration, and further stimulate their interest in actively trying and actively exploring science.

1. Activity objectives

(1) Understand that sound can be transmitted through the vibration of cotton thread, copper wire, and plastic rope.

(2) Learn to compare and observe, be able to predict and verify the problems explored, and make accurate records.

(3) Feel the fun of exploring scientific activities.

2. Activity preparation

(1) Experience preparation:

1. A preliminary understanding of how to play "Megaphone".

Guidance: Guide children to explore ways to make the microphone transmit sound.

(2) Material preparation:

1. ppt multimedia courseware: "Wonderful Microphone" and "Telephone Room".

2． A set of children's operation recording materials for two persons (a microphone tube connected by a cord, a microphone tube connected by a thin copper wire, a microphone tube connected by a plastic rope).

3. Venue preparation: a relatively open activity room in the park.

3. Activity process

(1) Show the microphone connected with cotton thread to stimulate children's interest in exploration 1. Children can freely play with the microphone connected by cotton threads and explore how to play the microphone.

Guidance: What did the teacher bring today? Can a microphone connected with cotton wire transmit sound? Ask two children to find a comfortable place and give it a try!

2． The group explored again and found that sound can be transmitted only by straightening the cotton thread and vibrating it.

Guidance points: Two children worked together to explore and found that the cotton thread must be straightened and the microphone placed close to the ear to transmit sound; the cotton thread vibrates when the sound is transmitted.

(2) Children explore in groups, guide them to explore the vibration transmission of sound through connecting objects, and record the experimental results.

1. Show three microphones connected with different connectors and learn to record them.

Guidance: Look! The teacher also brought two different microphones, one connected by copper wire and the other connected by plastic rope. Ask the children to compare the microphones connected by three different connectors to see which microphone is better. Are you good at transmitting sounds? Invite the children to be the little referees and record the results on the form while doing the experiment.

Guidance points: Introduce the recording form and guide children to learn the content and methods of recording.

2． Children work in pairs to experiment, compare which microphone tube connected with three different connectors has the greatest sound transmission ability, and record the results of the exploration.

Guidance points: Ask children to work in pairs to explore, and guide children to record purposefully: whether the connecting objects are straightened, whether they can feel vibration, and whether they can transmit sound.

(3) Sharing and communication, inspiring children to express their exploration and discovery of sound transmission in words.

1. Children communicate experimental results.

Instructions: Please tell the children about your exploration and discovery. Which microphone has the greatest ability to transmit sound?

Guidance points: Guide children to boldly speak out what they discovered during their exploration based on the results they recorded.

2. Play the courseware and learn the secrets of sound transmission.

Guidelines: Why can a microphone connected by copper wire transmit sound whether it is straightened or not? Let’s take a look at the secrets.

(Know that sound is transmitted through the vibration of the connecting object. Copper wire vibrates hard and fast, and the sound is easily transmitted to another microphone, so the copper wire can transmit sound regardless of whether it is straightened or not. The cotton thread and plastic rope are soft, and the loose cotton thread and plastic rope will suppress, weaken and eventually absorb the vibration, so that the vibration cannot reach the other microphone. Only the straightened cotton thread and plastic rope can transmit the vibration well and let the sound follow. The vibration of the straightened cotton thread and plastic rope is smoothly transmitted to the other end of the microphone)

(4) Understand the application of "microphone" in life, and initially understand the secret of telephone sound transmission.

1. Inspire children to find applications of microphones in life and understand the secrets of telephone sound transmission.

Question: Ask the children to think about what things in our lives apply the principle of "microphone" sound transmission?

2. Watch the courseware "Phone Room" and get a preliminary understanding of the secret of telephone sound transmission.

Guidance points: Guide children to initially understand the whole process of how the phone transmits our speaking voices and how to receive them.

IV. Extension of activities

(1) Put different "microphones" made by children in the science area to encourage children to continue to explore and discover more mysteries of sound transmission during class.

(2) Provide materials in the art area, encourage children to make different microphones by themselves, and stimulate children's interest in knowledge and desire to explore by trying and improving more "microphones".

Attached information:

1. The little secret of the microphone. The microphone uses the principle of sound waves causing vibration propagation of solids. Generally, the sound transmission capacity of solids is stronger than that of air and water. After straightening, the wires are similar to the solids, which can improve the sound transmission capacity, reduce the sound wave loss, and achieve the sound transmission effect. Sound is transmitted through the vibration of the connecting object. If the copper wire vibrates hard and quickly, the sound is easily transmitted to another microphone, so the copper wire can transmit sound regardless of whether it is straightened or not.

The cotton thread and plastic rope are soft, and the loose cotton thread and plastic rope will suppress, weaken and eventually absorb the vibration, so that the vibration cannot reach the other microphone. Only the straightened cotton thread and plastic rope can transmit the vibration well and let the sound follow. The vibration of the straightened cotton cord or plastic cord is smoothly transmitted to the other end of the microphone.
