"The Change of Shadow" Teaching Plan for Large Class

It is essential for teachers to prepare teaching plans before teaching activities, which is conducive to our scientific and reasonable control of classroom time. What formats should I pay attention to when writing lesson plans? The following is the lesson plan of "The Change of Shadows" compiled by me for your reference only. Welcome to read.

Shadow change: 1 activity target;

1, understand the basic laws of shadow changes in different periods, and know that shadow changes are related to light.

2, can complete the observation record.

Activity preparation: chalk, etc.

Activity flow:

1. Observe the figure in the morning:

The teacher led the children to the playground. Children in pairs, choose a place to stand, draw each other's figures with chalk, and write their names next to the figures.

The teacher helped the children with operational difficulties to complete the task of recording numbers.

2. Observation chart at noon:

The recording method is the same as in the morning. The children recorded the numbers at noon next to those recorded in the morning and compared them.

The teacher asked questions.

-"Have you noticed any changes in the shadow at noon compared with that in the morning? Why did this change happen? "

The children discuss, and the teacher listens to the children and gives guidance.

3. Observation chart in the afternoon:

The same method is used to record people in the afternoon.

-"Why are the three records different?"

Teachers and students discuss with each other and come to a conclusion.

The change of shadow teaching plan 2 activity goal: 1, to stimulate children's curiosity to explore various changes of shadow.

2. Guide children to gain the experience of shadow change through experimental observation.

3. Know that the change of shadow is related to the change of object position.

Activity preparation:

1, children's group activities, each group has a cartoon logo.

2. Operating materials: several flashlights, several glue bottles, pencils, erasers and building blocks.

3. Medals and trophies

4. courseware

5, tape recorders, projectors

Activity flow: 1. Passion leads to 1. The teacher led the children to play the game of stepping on the shadow.

Children enter the classroom with the music and choose their favorite seats to sit down.

3. Guide children to talk about the shadows of the objects they usually see.

4. Let the children guess riddles (it seems that I am not me, but it won't hide when I step on it, and it will follow me everywhere I go)

Ask questions in the form of riddles to stimulate children's desire to explore. During the experiment, groups were named after children's favorite cartoon images, and group competitions were held to cultivate children's spirit of unity and cooperation, stimulate children's spirit of unity and cooperation, and stimulate children's curiosity to explore shadow changes.

Second, explore the discovery 1, the teacher instructed the children's group to operate the materials to experiment and explore the changes of shadows.

2. The children's group explored and found the change of shadow.

Shadows can change direction.

② The shadow duration is short.

(3) shadows will move.

(Let children get the experience of shadow change through experimental observation)

Third, solve the problem 1, the teacher guides the child to solve the problem according to the problem raised by the child.

(1) Shadows change direction. Why?

The teacher asked the children to demonstrate their own practices.

(2) Guide children to watch the courseware A Jingle Day and answer questions.

(3) Teachers guide children to summarize: When the direction of light changes, the direction of shadow will also change.

(2) The shadow duration is short. Why?

(1) Let children demonstrate their own practices.

② Watch the courseware-Travel Notes of Big Head Son to further verify this change of shadow.

③ Teachers guide children to summarize: when the light shines obliquely, the shadow of the object is long, and when the light shines above the object, the shadow of the object is short.

(3) The shadow will move, why?

Let the children demonstrate in front of the screen.

(2) The teacher lets go of the shadow courseware for children to enjoy.

(3) Children perform hand shadow in front of the screen, and dance to the music, while observing the changes of their own shadows.

④ Teachers guide children to sum up: When light shines on an object, the object moves and its shadow moves.

(Through experimental demonstration, guide children to verify the correctness of their experiments and let them experience the happiness of success)

Fourthly, extend one of the functions of shadow play-shadow play.

Ask the children to watch the courseware-shadow play

Let children enjoy shadow play, and further stimulate their interest in exploration.

End: The children walked out of the classroom with the music.

The Change of Shadow Lesson Plan 3 Activity Target:

1. Guide children to actively explore the generation and change of shadows, and let children find that the generation and change of shadows are related to the change of light sources.

2. Cultivate the relationship of consultation and cooperation among children and encourage them to record the experimental results.

3. Guide children to understand the use of shadows in life and enrich their understanding of shadows.

Activity preparation: Each child has a flashlight, several small toys and cylindrical building blocks, a record card, a marker, a projector and multimedia courseware.

4. Test children's reaction ability and exercise their personal ability.

Let children feel happy and fun, and they should learn knowledge before they know it.

Activity flow:

First, hand shadow game introduction: guess small animals

Second, the generation of shadows.

1, the first operation observation: children take flashlights and toys to do shadow experiments in groups to explore the relationship between light, objects and shadows.

2. Communication: How do you help objects find shadows?

Guide children: Turn on the flashlight, the light shines on the board-there is no shadow, let the light shine on the shadow-the shadow appears on the board, turn off the flashlight-there is no shadow on the board.

3. Summary: Because there is light, objects block the light, so there is a shadow.

4. Discussion: What other light can reflect the shadow in life?

5. Summary: Sunlight, moonlight, lights and firelight in life can all reflect the shadow of objects.

Third, the change of shadow.

1. Play multimedia courseware and show children the shadow pictures in life.

Ask the children to observe. What objects have you found? What are the characteristics? What is the light source?

2. Communication: Have you found that the shadows in these lives are all the same?

3. Summary: Shadows are big and small, with various shapes.

4, the second operation observation: guide children to take pictures of objects from different directions, and find the orientation and size changes of shadows.

5. Communication: How did your shadow change?

6. Summary: The light is on the left and the shadow is on the right; The light is on the right and the shadow is on the left: the light is on the top and the shadow is small; The light is nearby, and the shadow is very big.

7. Record of the third operation: Let's try again and record your test results.

8. Comment record card.

Fourth, the use of shadows.

1. Communication: Do you know what shadows are used for in life?

2. Summary: People invented movies with the principle of shadow; This project uses the shadow of tall buildings to calculate the height of tall buildings; Scientists use the shadow of mountain peaks on the moon to calculate the height of mountain peaks; The artist invented a very interesting shadow play by using the principle of shadow.

3. Discussion: What inconveniences will shadows bring to life?

4. Introduction of shadowless lamp: In the hospital, if the doctor has a shadow during the operation and can't see clearly, a medical accident will occur, so he asked the scientist for help. The scientist invented a shadowless lamp, under which the shadow disappeared.

Activity expansion:

Learn the principle of shadowless lamp from parents and teachers.

Encyclopedia: Shadow is an optical phenomenon. Because objects block the propagation of light and cannot pass through opaque objects, dark areas are what we often call shadows. Divided into umbra and penumbra.

"Shadow Change" Teaching Plan 4 Activity Objectives:

1, use all kinds of senses, actively use your hands and brains, explore the secret of the shadow, and tell everyone what you have found.

2. Know that the change of shadow is related to the position of light and objects, and then gain the experience of shadow change in the exploration experiment.

3. In the process of exploration, let children feel the fun of discovery and cultivate their curiosity, thirst for knowledge and interest in scientific activities.

Activity preparation:

1, big screen, slide projector, flashlight.

2. A doll operated by several children, a story and a tape.

Activity flow:

1, let children solve riddles on the lanterns, stimulate interest in learning-"Have a good friend, come with me every day; Sometimes walking in front, sometimes walking behind; When I talk to him, I just don't talk. " (shadow)

2. Guide children to recall the relationship between shadow and light.

"Son, have you ever seen a shadow?"

"When will there be shadows?"

When sunlight and electric lights shine on us, there will be shadows.

"What else has a shadow?" Trees, flowers, houses, animals, etc. What about you on the playground? )

"Why is there a shadow?" (Children guess and discuss) Do experiments with flashlights to let children know that there are shadows because objects block the light. Guide children to know that where there is light, there is shadow.

3. Game: Guess the shadow

1) The teacher asked two children with obvious characteristics to hide behind the screen and let the other children guess who they were. Q: Who is he? How do you know that?

2) Please hide two children whose characteristics are not obvious, which will increase the difficulty of the game and arouse children's interest. The characteristics of shadows are related to objects. )

3) Play with games: stimulate children's desire for shadow exploration.

4. The teacher tells stories to children with hand shadow, and asks them to enjoy them.

1. Children are free to perform hand shadow in front of shadows.

B. Let the children further perceive the interesting phenomenon of shadows with hand puppets combined with music. When the children were in high spirits, the teacher suddenly turned off the lights and guided the children to observe the relationship between light and shadow.

5. Question: Where is the shadow? Why is there no shadow? (Turn on the light to ask further questions) There is light, why is there still no shadow? Shadow, object and light are closely connected, and without one, a shadow will not be formed. )

Activity extension: walking shadow

Children, when we were playing games just now, we walked with the shadow. Now the teacher asks a child to stay on the ground. Let's guess what his shadow will look like. The teacher holds a flashlight, illuminates the child from different angles, and lets the flashlight walk around the child to observe the change of the shadow, and naturally ends the activity by asking for re-exploration.

"Shadow Change" Classroom Teaching Plan 5 Activity Objectives

1, guide children to be interested in light and shadow and have the desire to explore.

2. Guide children to actively participate in practical activities and explore the relationship between light and shadow.

3. Cultivate children's abilities of observation, comparison, cooperation and judgment.

4. Learn to record your findings in various forms such as language and symbols.

5. Experience the sense of accomplishment in solving problems.

Teaching emphases and difficulties

1, how to hide your shadow.

2. What's the difference between yourself and the shadow?

Activities to be prepared

1, the weather is sunny, leading children to play shadow play and hand shadow play outdoors. The purpose is to help children accumulate experience about shadows.

2. The task of finding a shadow for children. On the one hand, cultivate children's sense of task, on the other hand, enrich children's perceptual knowledge.

Activity process

(1) Stimulate interest and introduce activities.

1. Let the children observe what shadows (poplars, teachers, children, tables, small chairs, etc. ) It's like being in a class.

2. Let children look for shadows outdoors: Let children run in the sun and shadows, see their own shadows, and understand that there are shadows in the sun and there are no shadows in the shadows.

3, children think about where there is our shadow? (Inspire children to tell the shadows under the light, fire, moonlight and flashlight)

Teacher: Children, if you look carefully, you will find shadows in many places. Why do those places have their own shadows?

As soon as this question was raised, the children discussed it, and soon many children thought of it. I saw my shadow in that place, because the light was on and the shadow disappeared as soon as it was turned off.

(2) Independent exploration to obtain the perceptual experience of light and shadow.

1, how can I hide my shadow? Ask the children to have a try. Please tell the children where they are hiding. Why are you hiding in these places? (Experience the role of light in shadow formation)

2. What are the similarities and differences between your own shadow and yourself?

The shadow is close to the outline of a person. Difference: People are colored and shadows are black. )

Try it, can our shadows be separated from ourselves?

The children tried various methods. Some children stood on the high platform, some children jumped up, some hid ... The shadow never separated from themselves. Finally, a child jumped very high. At the moment of his high jump, the children were surprised to find that the shadow was separated from him. As a result, the children imitated one after another and jumped up hard.

4. How can I make several children have only one shadow? The children try to talk in good groups.

(3) Throw out questions and expand.

Draw your own shadow. What should I draw when drawing shadows? (Light, people, shadows) Put on a special shape and take a look at your own shadow.

Teaching reflection:

In this scientific exploration activity, I have grasped the characteristics of children's strong curiosity and hands-on ability, so that children can discover scientific truth in full and active practical exploration, and the activity effect is good. However, there are also some problems, such as children's individual operations have no purpose, and they can't find problems well and experience the joy of success.

The change of activity goal of shadow lesson plan 6;

1, using various senses, actively explore the secret of shadow with hands and brains.

2. Understand the phenomenon that shadows will appear when light is blocked by objects.

3. Understand the relationship between the change of shadow and the position of light and objects, and gain the experience of shadow change in exploration experiments.

4. Pay attention to listening to and respecting peers' speeches in communication activities.

5. Experience the sense of accomplishment in solving problems.

Activities to be prepared

1, a big screen, a slide projector, 19 flashlight, shadow ppt, hand shadow video.

There are several dolls operated by children.

Activity flow:

1, exploring shadows: guessing riddles to stimulate children's interest in exploring shadows.

Let the children guess a riddle: I have a good friend who is with me every day, sometimes in front of me and sometimes behind me. I just don't talk to him? Guess who this is?

2. Say in the form of dialogue: I know the shadow.

Question: When have you ever seen a shadow?

What shadows have you seen?

3. Look at the ppt of the shadow. Please tell the children what shadows look like.

4. Explore why there are shadows.

If the child can't answer, ask the child to go to the edge of the big screen, let the child see if there is any shadow on the screen, and let the child make a comparison. With comparison, children will soon understand that with light, objects will block light and produce shadows.

Why is there no shadow in the classroom?

Teacher: Please think for yourself, why is there no shadow in our teacher?

Yang: Because there is no light.

Teacher: Please close your eyes. A shadow will appear in the classroom at once.

The teacher drew the curtains and turned on the lights to let the children look for shadows. When the children were in high spirits, they turned off the lights and asked, where is the shadow and why?

Teacher's summary: No matter what light there will be shadows, such as shadows in the sun and shadows in the moonlight.

5. Free exploration of shadows

Show me a flashlight.

Teacher: "The teacher also invited a good friend. Do you know him? What do you see when you turn on the flashlight? " The teacher demonstrated on the wall and a light appeared.

In a relaxed atmosphere, children play with operating materials, create a shadow between the flashlight and the object, and discover the characteristics of the shadow.

Ask children to operate: create a shadow between the flashlight and the object, and find the characteristics of the shadow. In this link, children are guided to observe the color and changing shape of the shadow through language prompts.

talk

Q: "What did you find while playing? How do you play? " Please show some children different findings. Teachers can also demonstrate the operation.

The teacher summed up: 1 It turns out that the shadow is black, just an outline, and there are many invisible things on the shadow. The position of the light source has changed, and the size of the shadow has also changed. The posture of the object has changed, and the shape of the shadow has also changed.

6, watch the hand shadow video to understand the hand shadow.

Teacher: Shadows are amazing. Hand shadow love will play games with us. Now let's see what cute little animals the hand shadow can become, and invite children to watch the video.

7. End of the activity: Learn hand shadow and play hand shadow games outdoors.

The teacher taught the children simple hand shadow movements. Let's go to the sun and see what interesting animals they will become. (outdoor photo-seeking)

Activity reflection

This science lesson will change the shadows. I want children to explore the changes of shadows through their own operations. When choosing this course, I think children should be unfamiliar with shadows, and they will not be very clear about the changes of shadows when expressing them in words. This is their own preset situation. Through my own actual teaching process, I reflected and made a simple comparison between my own preset situation and actual operation, and summed up the following points:

1, the teacher's guidance

In the process of children's operation, the guidance of teachers is the most important, especially when children are exploring shadows, teachers can operate in advance, and teachers should consider the problems in the process of exploration in advance, so as to guide the problems. For example, in exploring the length and size of shadows, teachers can operate by themselves, and put their own demonstration process in a link, so that children can explore first, so that they can compare and operate when exploring, not others. Also, when children feel the shadow, the teacher's guidance is also very important. Let the children do hand shadow in front of the big screen, so that the shadow of the hand will appear on the screen immediately, and the teacher does not need to describe it in more languages, so the teacher's guidance is very important in teaching activities. If the guidance is incorrect or not in place, it will lead to problems in the child's operation.

2. Preparation before the activity

Teachers in science exploration classes should be fully prepared and provide children with many operating tools. In order to let them explore the shadows, I prepared 18 flashlights for the children, so that the two children are a group, which is also an activity I specially arranged. In addition to exploring the secrets of shadows, I want children to learn to cooperate with each other in this link. Because my preparation work is not in place, it's messy to take things and put them away. There is no order, children don't line up and don't know manners, so in future teaching activities, I will pay attention to cultivating children's habits, consider problems more thoughtfully, make preparations in place, and make children orderly.

3. Progress of children

In this teaching activity, the child's early experience was unexpected by the teacher. When I asked why there was a shadow, Guo Zhixian's answer surprised the teacher. She said, "There must be people besides sunshine." Yes, a shadow must have two conditions: first, there must be light, and then there must be an object to cover it. The children's answers are so wonderful that they can express them in their own language that the teacher didn't expect them. In fact, not only herself, but all the children in the class found different changes in the shadow when they explored it, and they all expressed it in language. Although the language is not very accurate, they can tell the changes in the shadow, which shows that the children have made progress. Through this semester's study, they will find the changes of objects and explore for themselves, and they are really happy for their children's progress.

The activity is over, but it is worth the teacher's reflection. I will adjust my teaching activities according to my own reflective experience to make my class more interesting and make children like my teaching class more.

"Shadow Change" Lesson Teaching Plan 8 Activity Target

1. Let children explore shadows and get a specific physical examination about the formation and change of shadows.

2. Develop children's observation and imagination.

3. Stimulate children's interest and curiosity in exploring shadow phenomena.

Activities to be prepared

1. Light source such as lamp or flashlight. (for hand shadow games)

2. Children's book picture "What are the images of these hands".

Activity process

1. Arouse children's attention to shadows.

"Children, have you ever seen a shadow?" "When will there be shadows?" When sunlight and electric lights shine on us, there will be shadows. ) "What else has a shadow?" Trees, flowers, houses, animals, etc. ) "Why is there a shadow?" (Children guess and discuss) Do experiments with flashlights to let children know that there are shadows because objects block the light.

2. Guide children to observe the shadows and changes of objects. "Please go outside and see what your shadow is like?" "Please have a look again. What other shadows did you find? What are they like? Will it change? Why has it changed? How can I make myself invisible? " If we change the position of light, the shadow will also change. If we hide in the shade, there will be no shadow. Let the children change the position of light to observe the change of shadow. Guide children to read children's books and play hand shadow games.

"Let's play hand shadow games. The teacher made a shadow with her hand and asked you to guess what it was. Then learn from the teacher, ok? " Teachers and students play hand shadow games together. "We changed so many hands. Do you know why there are so many different hand shadows? " (Different postures of hands make different shadows. Activity suggestions inspire children to pay attention to the changes of street lamps according to their own shadows on the road at night.
