Teaching plan of great class science 1 activity goal;
1. In the process of exploration, it was found and recorded that objects would make sounds through vibration.
2. Experience the interesting process of feeling the vibration phenomenon in different ways.
Activity preparation:
1, New Year bell ringing video, beautiful piano sound, noisy sound, Jinbo software.
2. Operating materials:
(1) 6 drums with a few snowflakes on them.
(2) Six rubber bands are tied to a rectangular disposable plastic bowl.
(3) 6 small bowls and spoons filled with water
3. Record 18, 18.
4. Chinese characters: the process of sound and vibration activities;
Firstly, the video "Ring the Bell" is introduced to guide children into the topic of exploring sound. (Material preparation: bell ringing video, Chinese character "sound")
1, take a look at the video content.
2. Summary: Yes, when someone knocks at the door, the bell will-make a sound. If you don't knock at the door, the clock will have no sound.
Second, explore
1: It is preliminarily understood that sound is produced by vibration. (Material preparation: operating materials and recording paper and pen)
1, discuss what objects in life can also make sounds.
2. Doubt: Why do so many objects make sounds?
3, explore the operation:
(1) Introduce the operating materials (2) Assumptions before operation: How to make the above materials sound?
(3) Put forward operation requirements and record requirements:
A. try each material.
B.record your findings on the record card.
(4) Children's operation and teacher's guidance
A.drum: what about snowflakes?
What happened to the rubber band?
C. Small bowls and spoons filled with water: Knock with a spoon, and what will you find? What about the water in the bowl? )。
4. Exchange and discussion: What material makes a sound? What did you find?
5. Further feel the state after sound vibration: two children say hello while touching each other's necks and saying "hello"; Don't say hello, touch each other's neck and exchange feelings.
6. Summary: It turns out that objects in life sound because of "vibration", which is manifested as "vibration" in Chinese characters. The sound stopped when we stopped them from moving.
Third, listen to the sounds in life and distinguish between music and noise (material preparation: piano sound+noisy music, Jinbo software)
1. What kind of sound is good for communication and discussion?
2. Enjoy the prepared music, observe the software screen and talk about the phenomena and feelings you see.
3. Summary and extension: those sounds that sound comfortable and pleasant are called music; And some voices are too loud and harsh. This sound is called noise. Go back and find out, what are the pleasant sounds and noises in life?
Wonderful sound teaching plan for the goal of science 2 activity in large class
1, through exploration activities, let children know how sound is generated and that objects with different materials can make sounds.
Different voices.
2. Willing to tell the results of exploration in complete language.
3. Cultivate auditory discrimination and stimulate interest in exploring the world around you.
Activities to be prepared
1, Children's experience preparation: Please guide children to listen to and distinguish various sounds in life at home, such as bells, electric bells, speakers, etc.
2, material preparation:
(1). There are various musical instruments such as tambourine, triangle, wooden fish, small bell, round dance board, tambourine, bottle cap, etc. on the desktop of each group.
(2) Collect cartons, paper cups, threads, cowhide tendons, milk bottles and other items with children.
(3) Recorders with all kinds of pleasant and harsh sounds.
Activity process
1. Perception of sound through exploration
(1) Play the instrument on the desktop by yourself, and let the children know how the instrument sounds.
Teacher: There are many small musical instruments here today. Just try it. How should you play with them?
Ask children to play musical instruments freely, and explore ways to make musical instruments sound, such as knocking, shaking, touching, patting, playing and shaking.
Teacher's summary: Musical instruments can make sounds. Different musical instruments make different sounds and have different methods of making sounds.
(2) Through operation, understand the causes of sound.
The teacher introduced the method of small experiment: put the bottle cap on the drum and let the children know the object while playing the drum. ※
Make a sound by vibrating.
Let children play musical instruments freely again, and let them feel the sound of objects caused by vibration. ※.
Understand the reason why people make noise. ※.
Teacher: We are standing still. Why should we make a sound to speak?
Please touch your throat and shout "ah-". Then let the children say their feelings (guide the children to feel the vibration of the vocal cords).
Teachers and children have the same conclusion: no matter what vibrates, it will make a sound, and it will not make a sound without moving.
2. Try independently and explore the sound.
(1) Let the children try to make the objects in the activity room make a sound.
(2) Guide children to communicate their own operations and discoveries.
Teacher: Little friend, what noise did you make just now? In what way? Encourage children to speak out their exploration and exploration results boldly.
(3) Teacher's summary: Everything in life can make a sound, and there are many ways to make a sound.
3. Listen, play and recognize these sounds.
(1) The teacher plays two recordings. Let the children listen and say. What is the difference?
(2) Teacher's summary: There are good voices and bad voices. The beautiful voice is called music, and everyone likes to listen to it. This unpleasant sound is called noise. Listening too much will be harmful to people's health. Therefore, children can be taught to speak quietly in game activities to avoid noise.
4. Do what you want and make your own toys.
Instruct children to make their own toys with the collected items, such as paper box piano, paper phone, seven-tone bottle and so on. Then play with your own instrument and experience the wonder of the sound.
Wonderful sound teaching plan of scientific design intention of large class 3;
Sound is everywhere, everywhere. For children in large classes, sound is familiar, but how it is produced is unfamiliar. On the other hand, as children grow older, their voices get louder and louder, and some even like to scream loudly on purpose. In order to cultivate children's learning attitude of bold exploration, active attempt, flexible thinking and hands-on operation ability, and cultivate good speaking habits, I designed this tentative, operational and exploratory scientific learning activity to guide children to discover the wonder of sound in life, know how sound is produced, understand noise and music, know how to avoid noise in life and feel the pleasure of scientific exploration.
Activity objectives:
1. Find out the cause of sound, and know that different objects make different sounds after vibration.
2, can distinguish between music and noise, know the harm of noise.
Focus of activities:
Knowing that objects produce sound through vibration, different objects can produce different sounds.
Activity difficulty:
Understand the hazards of noise and avoid making noise in life.
Activity preparation:
1, children's operating tools: bells, tambourines, triangles, glass bottles, paper, plastic bags, cartons, rubber bands, rice.
2. The teacher's operating tools: drums, recordings of various sounds, and three glass cups filled with water.
Activity flow:
First, the game: "The cup can sing" arouses children's interest.
Second, explore different voices.
1. Guide children to make their bodies make sounds as much as possible, such as clapping their hands and stamping their feet.
2. Guide children to make objects make sounds, and make different sounds after sensing different objects vibrate.
Third, the small experiment "rice baby dancing" explores the causes of sound.
1, children put rice grains on the drum surface and tap the drum surface to observe the phenomenon.
2. Discuss the reason why Mi Bao can dance.
3. Experiment again, put one on the drum surface, tap the drum surface, and feel the principle that objects vibrate to produce sound.
Summary: All kinds of sounds are caused by the vibration of objects. When you beat the drum, you can hear it and feel the vibration of the drum surface. People can speak because of the vibration of vocal cords in their throats.
Fourth, help children understand music and noise.
1. The teacher plays two recordings for the children to listen to. What is the difference? What kind of sound is nice? Beautiful and pleasant voice is called music; Harsh, ugly and messy sounds are annoying. This is called noise.
2. Talk about what is music and what is noise in life.
3. Talk about the harm of noise to our health? What should we do when we hear unpleasant noise?
4. How can children avoid making noise according to their own lives?
Verb (abbreviation of verb) Teacher's summary:
Children know that the vibration of objects makes sounds, and different objects make different sounds. The pleasant sound is music, and the unpleasant sound is noise. Listen to more music, protect your ears, don't listen to noise, and don't make noise.
Design concept of wonderful voice lesson plan 4 in large class science;
Scientific activities in kindergartens focus on guiding children to know the natural environment, observing natural phenomena, cultivating children's desire to explore natural science, and enhancing children's thinking abilities such as self-observation ability and judgment and analysis ability. Sound phenomenon belongs to one of the goals of science education in large classes. In order to let children know the causes of sound, I designed this "wonderful sound" activity, which aims to let children explore how sound is produced and cultivate their desire for scientific exploration through hands-on operation.
Second, the activity objectives:
1, perceive and understand the generation of sound, and know that objects with different materials can make different sounds.
2. Enhance the ability to distinguish and judge sounds.
3. Cultivate interest in exploring natural phenomena.
Third, the activity preparation:
1, I'm familiar with some sounds in my life, such as the sound of the phone, ringtones, etc.
2. origami frogs, electro-optic paper, plastic bags, plates, beans, cans and various musical instruments.
3. Multimedia courseware.
Fourth, the focus and difficulty of the activity:
Perceive the generation of sound and know that different objects can make different sounds.
Verb (abbreviation of verb) activity flow:
1, guess the perceived sound.
Teacher: Hello, children. Today, I brought some familiar voices. Do you want to know what they are?
Play the courseware, some voices from nature, the wolf.
(Layered playback, you can play one sound in the first time, several kinds in the second time, and increase one by one) Teacher: Your ears are really smart, kid. You have guessed. Do you know how these sounds are produced? (leads to questions) 2. Play and explore the sound.
Children are divided into three groups, the first group: musical instruments, the second group: waste materials, and the third group: plates and beans. ) teacher: the teacher puts something on each child's chair, which can make a nice sound. Please take it out and play it to see how the sound is produced. Children can operate freely, and teachers can tour to guide.
(2) Ask individual children to speak out their findings boldly. Objects collide and vibrate to produce sound.
③ Let children put their hands on their throats to further experience the sound generated by vibration.
Teacher: Everyone was playing just now. Let these objects make a sound. Are these sounds the same? Play with these items again. Explore further that different objects make different sounds.
3. Look for it and make a sound.
Teacher: Just now. Everyone plays with all kinds of things and makes them make different sounds. Now, we're taking nothing. Can we make some noises ourselves?
Such as: clap your hands, clap your legs, step on your feet, scream, etc.
Remind children to avoid making screaming noise and affecting others. ) 4. Listen and enjoy the sound.
Teacher: Just now, some children screamed. What kind of sound is nice?
Guide children to distinguish different music, know how to listen to music more, avoid noise and protect our ears from harm. 5. Activity expansion:
In fact, there are many voices around us, and what we played today is only a part of them. I believe the babies in our class can find more and better voices. Look carefully and listen carefully, and bring back what you found and heard, okay?
Teaching plan for wonderful sound of science in large class 5 activity goal
1. Know all kinds of sounds and learn to distinguish them.
2. Shoulder soap uses various objects and methods to imitate sound purposefully and experience happiness in operation.
3. Willing to put forward their own views and verify them in the activity.
Activities to be prepared
1. yogurt cups, hot water bottles, dried peas, paper, paper matchboxes, wooden boards, stainless steel cups, chopsticks, plastic bags, cups of different heights and other materials.
2. Tapes with various sounds. VCD of "Scientists Invent by Using Sound".
Activity process
First, put forward the theme.
1. What sound have you heard? The children discuss and answer.
2. What is the loudest sound you have ever heard? What's the smallest sound?
Second, listen to the beautiful voice.
Children listen to the tape (rain, tiger barking, lion roaring, bird singing, thunder, etc.). ), and tell me what they heard. Imagine when these voices will appear and express them in words.
Third, I will make a sound.
1. The teacher hit each other with yogurt cups, making the sound of running horses, and then distributed various materials to the children, and asked them to try to make various sounds and create various sound effects in groups of three.
2. When children operate, teachers can guide children to think about what sound effects they want to create and encourage them to try in various ways.
Children take turns to show you the sound effects they made, and other children appreciate and imitate them. For example, shaking a box of dried peas-the sound of rain dripping on the canopy; Knead the cardboard into a ball-footsteps on the road ...
Discussion: What sound do I like?
Let children know about music and noise in the discussion, know about the sound that is beneficial and harmful to us in life, and know how to make music to avoid making noise.
5. Watch VCD to learn about examples of scientists using sound to serve human beings, such as sound wave mosquito repellent. Encourage children to use their brains and become inventors themselves.
Activity expansion
1. Explore the use of painting and dance language to express various voices in group activities.
2. Language activities: the poem Bazaar-Bazaar. Arouse children's related sound experience, and enter the beautiful and unique artistic conception of poetry while actively thinking.
Attached poem
Put on your boots and take a walk in the Woods.
Bazaar!-Bazaar!
Benedict heard the sound.
I'm just hiding in the Woods.
Climb the pine tree,
Boom, boom, boom, boom, boom
Ji Ji flew into the green forest.
Sasha vujacic swished into the black hole.
Everyone squatted silently out of sight.
Staring at "Bazaar-Bazaar" is getting farther and farther.
