As an unknown and selfless educator, it is necessary to prepare detailed lesson plans. Writing lesson plans helps to accumulate teaching experience and continuously improve the quality of teaching. So how should the lesson plan be written appropriately? The following is the lesson plan "Somersault Capsule" that I carefully compiled for large classes. It is for reference only. Let's take a look at it together. Large class lesson plan "Somersault Capsule" 1

Activity goals

1. Be interested in the interesting phenomena of force in life and have a desire to explore further.

2. Understand through experiments that the small capsule’s somersault is a phenomenon of shifting the center of gravity.

3. Learn to use experimental methods to verify your ideas.

4. Let children learn preliminary recording methods.

5. Be interested in scientific exploration and experience the mood that active exploration brings success.

Activity focus

Be able to understand the reason why the steel ball somersaults in the small capsule.

Precautions

Safety of capsules and steel balls.

Activity preparation

Capsules, mung beans, steel balls, screws, paper slides

Activity process

1. Introduction to the activity: telling stories, Arouse children's interest

There is a small capsule that can perform in the acrobatic troupe. One day, the leader of the acrobatic troupe asked Little Capsule to come up with a new show, which involved somersaulting down the slide. This stumped the little capsule. It kept practicing and the children helped it take a look. (Demonstrates the small capsule sliding down the slide) Is this a somersault? When it was anxious, the leader of the acrobatic troupe said to it: "Your stomach is empty, how can you do somersaults?" You have to put something in and give it a try. The little capsule thought: What should I put in it to do somersaults? Children, please help it think about it.

Teacher: What do you think should be put in the small capsule to make it do somersaults? Why?

2. Activity implementation:

1. Children’s understanding of materials.

Teacher: What did we take out? What are the differences between these three materials? Weigh it in your hand and roll it on the plate to see.

Summary: These three materials have different shapes, different weights, and different rolls.

2. Children make guesses.

Teacher: Which of these three things do you think can be put into a capsule to make it do somersaults?

3. Children conduct experiments.

Teacher: What materials are put in the capsule to make it do somersaults? Can the other two materials make the capsule somersault?

4. Children record experimental findings.

5. Children share experiments.

Teacher: Why can steel balls make small capsules do somersaults? How is it different from the other two materials?

3. Summary of activities:

Teacher’s experience summary: By making the capsule do somersaults, we know that round and heavy things can make the capsule do somersaults. Long and light ones are not allowed. We can come down and try something else that can make the little capsule do somersaults.

Extension of activities

Look for materials that can make small capsules do somersaults, and discover their unique similarities. Large class lesson plan "Somersault Capsule" 2

1. Design intention:

There are many phenomena that children are interested in in real life, and they contain certain scientific principles. This activity focuses on guiding children to learn by doing, think by doing, experience science by doing, explore science, and cultivate children's scientific literacy from an early age.

2. Activity goals:

1. Through operating activities, perceive the rolling phenomenon of objects due to the movement of the center of gravity.

2. Be able to express your findings in language and record the process of exploration.

3. Improve observation skills and interest in exploring things.

3. Activity preparation:

1. Pre-knowledge preparation: Understand that round objects (such as small balls and small steel balls) can roll.

2. Material preparation: empty capsules, small steel balls, match heads, paper balls, transparent tubes made of Sprite bottles, egg shells, glass balls, glass balls, recording forms, multimedia courseware, and intelligent eggs.

4. Activity process:

1. Organize games to stimulate interest.

(1) Present intelligence eggs (placed in transparent tubes) to arouse children’s interest in exploration.

(2) Teacher: My intelligence egg may be dry, and it can also perform acrobatics. Look (demonstration of making the intelligence egg do somersaults in a transparent tube), how is this intelligence egg doing in the tube? ? (Children discuss while watching) Why does the Intelligent Egg do somersaults?

2. Hands-on operations for young children

(1) Do you want to know why the intelligent egg does somersaults? Then you have to think about it and give it a try. Every child has a transparent tube, and the small capsule is like an intelligent egg. Now try it and see if your little capsule can do somersaults in the transparent tube.

(2) Child operation: It is found that the small capsule cannot do somersaults.

(3) Why can’t this little capsule do somersaults? Is there any way you can make the capsule do the same somersaults as the intelligence egg? Let the children carry out the operation again with questions. Try to put small paper balls, match heads, small steel balls and other objects into the small capsule to see if these objects can make the small capsule do somersaults.

(4) Teachers and students operate and test together. Encourage children to tell about their own operations and record the results.

3. The discoveries made during the communication between teachers and students.

(1) How did you play just now? Did you find anything interesting?

(2) Ask individual children to tell and demonstrate their findings.

(3) Teachers and students jointly verified that after the steel ball is placed in the capsule, the capsule will turn somersaults.

4. Understand the principle of capsule somersault.

(1) Why does the capsule turn somersaults when a steel ball is placed in it, but does not turn somersaults when a match head or small paper ball is placed in the capsule?

(2) Watch the multimedia courseware (see attachment) and understand the real principle of the steel ball making the small capsule do somersaults: because the small steel ball is round and can roll freely, and it is heavier than the small capsule, so it is used as a small steel ball When it rolls to this end of the capsule, the other end of the capsule tilts up; when it rolls to the other end, this end tilts up again. With continuous rolling like this, the small capsule keeps flipping up like an acrobat. Somersault is coming.

(3) Reveal the secret of how the “intelligent egg” can turn somersaults.

Teacher: Can you guess why the intelligent egg does somersaults? What's in it?

After the children make guesses, open the intelligence egg and look at the glass ball inside, thereby helping the children further understand: When a hollow object such as a capsule is filled with a heavy object that will continue to roll, as long as the heavy object rolls , it will drive objects such as capsules to turn somersaults.

5. The game of "small capsule somersault" while listening to music is over.

5. Activity extension:

Provide various capsule-like hollow objects and various operating materials such as glass balls, small steel balls, and small marbles in the technology operation area to encourage children to further operate explore.

6. Activity evaluation:

1. Operate and explore the good "guidance". At the beginning of this activity, by setting up a problem scenario, the children's intention to learn is guided, and the children's impulse to explore and discover is stimulated. With the question "Why does the intelligent egg do somersaults?", the children carry out the operation and exploration activities with great devotion and concentration.

2. Dare to “let go” during operational exploration. During the activity, the teacher fully believed in the children's independent exploration ability and dared to let go, but did not let it go.

For example, in the process of trying to make the capsule do somersaults, children will inevitably have some difficulties and failures. However, the teacher does not provide them with ready-made conclusions and methods, but encourages the children to try again, or ask their peers for advice, or cooperate to discuss, and then Solve problems, acquire experience, and truly turn the process of exploration and learning into a process of learning to learn and create. In this process, children's autonomy and enthusiasm can be brought into full play.

3. It can be "activated" after operating and exploring. After each operation exploration, teachers can inspire children to express their operation results in language, so that knowledge and experience can be internalized in children's minds and continuously enriched through mutual exchanges and discussions with peers and recording activities. Teachers are also good at raising questions, inspiring children to think and guess, and then continue to explore and discover until the problem is solved. For example, when the child discovered that the small capsule could not do somersaults during the first operation, the teacher immediately asked questions such as "Why can't your small capsule do somersaults?", "Is there any way to make it do somersaults like the smart egg?" The children tried again and discovered the secret of the small capsule somersault, and naturally acquired some new experiences and knowledge. Large class lesson plan "Somersault Capsule" 3

Activity goals:

1. Through operating activities, perceive the tumbling phenomenon of objects due to the movement of the center of gravity.

2. Be able to express your findings in language and record the process of exploration.

3. Improve observation skills and interest in exploring things.

Activity preparation:

1. One set of experimental equipment for children: empty capsules, tracks, plastic beads, sand, small sticks, and small steel balls.

2. Guess, experiment record sheet, and pen.

3. Teacher’s magic props, background music, and focus shift principle courseware

Activity process:

1. Introduction of magic to stimulate children’s interest.

1. The teacher sets the music for the magic show.

2. Ask the children to talk about what magical phenomena they have seen.

Teacher’s summary: These are magic tricks that allow people to use special props to perform.

3. Reveal the secret of magic

2. Show the magic capsule to arouse children’s interest

Teacher: I also brought a guest today, everyone knows it ? Little Capsule will perform a magic trick for everyone to see who can discover where his secret is.

1. Teacher’s demonstration

Teacher: What did you see? Guess why the little capsule does somersaults?

Teacher: Do you want to know why the teacher’s little capsule does somersaults? Then you need to use your brain to think about it and give it a try. The teacher has prepared a small capsule and a track for the children under the chair. Now everyone has a try. Carefully put your small capsule into the track and see if it can do somersaults like the teacher's.

2. Children try to operate and use their own methods to make the capsule do somersaults

Teacher: "Can your little capsule do somersaults?" "Why can my little capsule do somersaults?" , but your little capsule can’t do somersaults?”

3. Observe and compare, and trigger conjectures.

1. The teacher reveals the secret of capsule somersaults

Teacher: Why can’t your little capsule do somersaults like the teacher’s? Because there is a little baby in the teacher's little capsule. This little baby may be small beans, small steel balls, sand, or small sticks (show pictures of the materials).

2. Understand the materials and their basic characteristics.

(1) Ask children to use various methods to perceive and tell.

Ask children to use pinching, touching, weighing, looking, etc. to perceive the differences between the four materials, and try to use their own In words, describe the similarities and differences between these things.

(2) Summary: Steel balls and small beans are both spheres and can roll in any direction, but steel balls are heavier;

Small sticks can only roll in one direction, and sand is Those that are spread out cannot be rolled.

Ask the children to guess: Which of these materials will make the capsule do somersaults when placed in a small capsule?

3. Children guess, discuss, and fill in the guessing table.

The teacher introduces the record card and asks the children to fill in their guesses in the guess column marked with a question mark, and put a √ if they think it is true. Plastic bead diagram, sand diagram, steel bead diagram, stick diagram? Small hand diagram

4. Children’s hands-on operations (music)

1. Verify the guess

Teacher: Do you want to verify your guess?

Ask the children to first put the material they guessed into a small capsule and try it on the track, and then put the remaining three materials into small capsules and try it out. See which kind of material put into the capsule can make it do somersaults, and record the results of the operation. In the column of the small hand diagram, put a √ and an × in the column of the small hand diagram.

2. Communicate the results of exploration

Please select a child from each group to share the results of your experimental records with everyone, show the record cards of individual children, and ask him to express himself The operation process: how to imagine, how to verify, and what the results are.

3. Teachers and students jointly verified that after the steel ball is placed in the capsule, the capsule will turn somersault.

Teacher: Guesses are just ideas. You have to try them out before you know. We made a guess just now, and then we verified the operation and found out who made the capsule do somersaults?

Teacher: Why does the capsule turn somersaults when small steel balls are put in it, but why does the capsule not turn somersaults when plastic beads, sand, and small sticks are put in it?

Children’s discussion, the teacher guides the children to analyze the characteristics of the materials.

4. Demonstrate courseware to understand the principle of capsule somersault.

Watch the multimedia courseware to understand the true principle of steel balls making small capsules do somersaults.

Teacher’s summary: Because the small steel ball is a sphere and can roll freely, and it is heavier than the small capsule, so when the small steel ball rolls to this end of the capsule, the other end of the capsule tilts up; When it reaches the other end, this end tilts up again, rolling like this one after another, and the small capsule does somersaults like an acrobat. This interesting phenomenon is called weight shift. If we put a spherical object of moderate size, rolling, and with a certain weight into a hollow object like a capsule, then as long as we let the thing inside roll, it will drive it to do somersaults continuously and regularly.

5. Listen to music and play the little magic of "small capsule somersault"

1. Freely display the small capsule somersault on the track

2. Expansion: (1 ) Teacher: We can make the capsule do somersaults in the track. Where else can you make it do somersaults?

(2) Can you make the small capsule that can do somersaults stand still? Think about why it also stands?

(Freely explore the "magic capsule" in music and the game ends)
