"Wonderful Shadow" large class lesson plan

As a faculty member, we often need to prepare lesson plans. Writing lesson plans helps us accurately grasp the key points and difficulties of teaching materials, and then choose appropriate teaching methods. So what does an excellent lesson plan look like? Below is the "Wonderful Shadow" lesson plan for large classes that I compiled for your reference. I hope it can help friends in need. "Wonderful Shadow" Large Class Lesson Plan 1

Design Intention

Shadow is something that young children can see almost every day, and it is also a topic of interest to them. Various changes, such as the shadow becoming larger and smaller, appearing and disappearing, arouse children's strong curiosity and desire to explore. The best way is to let children understand the close relationship between shadow and light, stimulate children's curiosity and interest in shadow, and let children explore by doing, looking, and playing. Therefore, "Wonderful" is specially designed. Shadow" activity.

Activity goals

1. Explore the causes of shadows and initially understand the relationship between shadow changes and light.

2. Be able to make reasonable guesses about the relationship between light and shadow, and be willing to operate and verify.

3. Cultivate children’s curiosity about things and be willing to boldly explore and experiment.

4. Be willing to try boldly and share your experiences with your peers.

5. Stimulate children’s interest in scientific activities.

Activity preparation

Darkly lit classroom, flashlight, various toys, dolls, recording paper, etc.

Activity process

1. Introduction of guessing games to stimulate children’s interest in activities.

Ask the children to guess the riddle: There is a good friend who walks with me every day. Sometimes he walks in front of me and sometimes he walks behind. I talked to him, but he didn't speak.

2. Organize children’s manipulation experiments to understand the causes of shadows.

1. The teacher asked questions based on experience: Where have you seen shadows? Why is there a shadow? Where are there no shadows?

2. Children take out flashlights and toys and do shadow experiments in groups to see what they find? (Teachers participate)

Understand one of the causes of shadows: there are shadows where there is light, and there are no shadows where there is no light.

3. Guide children to conduct exploratory experiments, shine a flashlight on toys and hands, and discover the relationship between shadows, objects and light through their own experiments.

Discover the second cause of shadows: shadows occur when opaque objects block light.

3. Children operate and explore, and understand that the changes in shadow are related to the distance and position of light and objects.

Children work in pairs, use a flashlight as a light source to illuminate the doll from different distances and angles, observe the changes in the size of the shadow of the doll, and make records.

Summary: When the light is closer to the object, the shadow becomes larger. When you are far away from an object, the shadow becomes smaller. When the object is photographed by light from a lower place, the object becomes larger. When the object is photographed by light from a higher place, the object becomes smaller.

4. Inspire children to tell what kind of light can cast shadows?

Let children know that there is shadow only when there is light. Teacher's summary: Sunlight, moonlight, lamplight, candlelight, etc. can cast shadows of objects.

5. The use of shadow.

1. Communication: Do you know what uses shadows have in life?

2. Summary: People invented movies using the principle of shadow; engineers used the shadow of tall buildings to calculate the height of tall buildings; scientists used the shadow of mountain peaks on the moon to calculate the height of mountain peaks; artists invented using the principle of shadow A very interesting shadow puppet show.

Extension of the activity

In the science area, various cardboard cutouts of Journey to the West character cards, flashlights, etc. are provided, and children are organized to play shadow puppet games and continue to explore the secrets of light and shadow.

Reflection on activities

In the activities, first grasp the cognitive characteristics of the children, create a lively and interesting atmosphere, let the children actively discover themselves, and see through doing Take a look, play with it, and let the children observe and explore issues such as the generation of shadows and the secrets of shadows while playing.

Secondly, through multiple game experiences, children have gained rich experience in the generation and changes of shadow phenomena, and guided children to fully express their opinions, cultivating children's innovative spirit and enabling them to Young children experience the fun of manipulation and exploration. "Wonderful Shadow" Large Class Lesson Plan 2

Activity Objectives

1. Through exploration activities, gain a preliminary understanding of shadow-related knowledge.

2. Cultivate children’s interest in scientific activities during the process of exploration and observation.

3. Be able to complete the exploration and understanding of simple scientific phenomena through experiments in situations, and be willing to express the discovered results in your own language.

4. Fully experience that “science is all around you” and develop an interest in discovery, exploration and communication in life.

Activity preparation

1. Several washbasins filled with water, mirrors, flashlights, wooden blocks, books, potato chip cans, and glasses.

2. Each child has a record card and crayons.

Activity process

1. Let the children search in the water basin: What did they find? Preliminarily perceive the shadow.

Children observe and search in the water basin. Through observation and communication, they initially perceive that what they see in the water is the shadow of an object.

2. Provide a variety of physical objects so that children can explore and understand which objects can help us see shadows.

1. Guess: Among these objects, who can help us find the shadow?

Ask the children to write down their guesses on the record card.

The physical objects provided include: mirrors, flashlights, wooden blocks, glass, books, and potato chip cans.

After the children have recorded their records, let them talk about their guesses and compare them with other children. Is it the same as other people’s guesses?

2. Give it a try: Who can guess? Right? Let’s give it a try.

Children try, operate and record.

Ask the children to explore and record the experimental results on the card, and compare them with their guesses. Are they the same?

3. Tell the results and process of the operation.

Compare with your friends to see if you have any new discoveries? Or is there anything you don’t understand?

Children’s discoveries may include: records of potato chip cans Some can help us see shadows, but some cannot. Teachers can guide children to explore again: Why is this?

Let children find the answer on their own.

3. Game: Step on the shadow.

The shadow can be seen, but can it be caught? Let’s give it a try!

Children play the game of stepping on the shadow and catching the shadow, and once again perceive the characteristics of the shadow.

4. Expand new experiences

What are the uses of shadows in life?

Children tell based on their own life experiences: People use shadows to create images The principle invented the camera, the television, and the video recorder also released shadows, shadow puppets, hand shadow games...

Extension of activities

There are many little secrets in the shadows, We can search again with the children, parents and parents, and then tell everyone about your new discovery, okay?

Reflection on the activity

Shadows have always been a topic of interest to children. Embodying the concept of integrating scientific education into the core of children's lives, the design activities aim to allow children to explore shadows, understand the close relationship between shadows and light, stimulate children's curiosity and interest in shadows, learn scientific methods, and cultivate Develop a good scientific attitude.

At the beginning of the activity, I introduced the hand shadow game. The game is a favorite way for children. It can make children quickly concentrate and quickly enter the role of the classroom. Then let the children explore by themselves. Discover the shadow, let the children gain true knowledge from practice, let the children explore and discover by themselves, cultivate the ability of independent cooperative inquiry, and figure out the mystery of the shadow through active discussion, communication and careful observation, and the children's innovative spirit and thinking Ability and spark. After the first operation, the children learned the principle of "because there is light and objects block the light, so shadows are produced". Then they introduced the children's life experience and watched the multimedia courseware "Shadows in Life", and learned from the children's cognition Set out, exchange existing life experiences, let them speak freely, develop language and thinking, and at the same time arouse their interest in the shape, size, and change of shadows, which triggers their interest in second exploration. The focus of the second exploration is to guide children to illuminate objects from different directions and discover the changes in the direction and size of shadows. In this operation, not all the children successfully discovered the secret of shadow change, so I asked several successful children to come to the front desk to demonstrate the operation. I gave a guidance summary, and then asked all the children to perform the third operation. , and asked the children to record the results of the operations, and the effect was very good. All the children experienced the joy of success in scientific exploration activities and developed self-confidence. Finally, the children were introduced to the uses and disadvantages of shadows in life. Unfortunately, children have very little experience in this area.

In this scientific exploration activity, I captured the characteristics of children who are curious about scientific phenomena and are hands-on, so that children can discover scientific principles through fully independent practical exploration, and the activity effect is good. But there are also some problems, such as children's individual operations without purpose, so they are not able to discover problems well and experience the joy of success. "Wonderful Shadow" Large Class Lesson Plan 3

Design Intention:

Playing with shadows is the most interesting game for children. The teacher closely grasped this characteristic of children and designed this activity. Use the hand shadow game as an introduction, and then gradually deepen: how shadows are produced - the changes of shadows - further explore the use of shadows and end this activity, so that children can comprehensively and systematically master the perceptual experience of "light and shadow" : When light shines on an object, the object blocks the light and creates a shadow.

In this activity, the teacher fully focused on children and teachers as the leader, cultivating children's interest in exploring scientific practices and developing Children's ability to observe, compare and judge allows children to develop the habit of actively exploring science from an early age, and encourages children to experience the joy of success by themselves, and further experience the pleasure brought by self-confidence.

Activity goals:

1. Guide children to actively and interestedly explore the production and changes of shadows, so that children can discover that the production and changes of shadows are related to related to changes in light source.

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

3. Cultivate negotiation and cooperative relationships among children, and encourage children to record experimental results.

Activity preparation:

Each child has a flashlight, a number of small toys and cylindrical building blocks, a note card for each person, a marker for each person, a projector, and multimedia courseware .

Activity process:

1. Introduction to hand shadow game: Guess the small animal

2. Production of shadow.

1. First operational observation: Children use flashlights and toys in groups to do shadow experiments, exploring and discovering 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 and the object blocks the light, there is a shadow.

4. Discussion: What other lights can cast shadows in life?

5. Summary: Sunlight, moonlight, lights, and firelight in life can all cast shadows of objects.

3. Changes of shadows

1. Provide multimedia courseware to show children pictures of shadows in life.

Ask the children to observe, what shadows of objects did they find? What are the characteristics? What is the light source?

2. Communication: Do you find that these shadows in life are all the same?

3. Summary: Some shadows are big, some are small, and there are various shapes.

4. The second operational observation: guide children to illuminate objects from different directions and discover changes in the direction and size of shadows.

5. Communication: How did your shadow change?

6. Summary: When the light is on the left, the shadow is on the right; when the light is on the right, the shadow is on the left: when the light is above, the shadow is small; when the light is on the side, the shadow is large.

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

8. Commentary record card.

4. The use of shadow.

1. Communication: Do you know what uses shadows have in life?

2. Summary introduction: People invented movies using the principle of shadow; engineering 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; artists use the principle of shadow A very interesting shadow puppet show was invented.

3 Discussion: What other inconveniences does shadow cause in life?

4. Introducing the shadowless lamp: In the hospital, if there is a shadow that makes the doctors unable to see clearly during surgery, medical accidents will occur. So they asked scientists for help, and the scientists invented a shadowless lamp. There will be no shadows under this kind of light.

Activities extension:

Understand the principles of shadowless lamps from parents and teachers.
