As a teaching worker, you often need to prepare lesson plans, which help students understand and master systematic knowledge. How should lesson plans be written? The following is a scientific and interesting fingerprint lesson plan for large classes that I have carefully compiled. You are welcome to share it. Scientific and interesting fingerprint lesson plan for large classes 1
Design Intention
As a familiar physiological phenomenon in children’s lives, “fingerprints” are often ignored, and teachers have never guided children to purposefully Therefore, children have not yet formed a clear understanding of "fingerprints". After watching the cartoon "Black Cat Sheriff" during a recess activity, the children became very interested in fingerprints. Therefore, in response to this situation, I designed the scientific activity "The Secret of Fingerprints" to enable children to discover the secrets of fingerprints while exploring their own fingerprints. Let children "learn by playing and learn by playing". In terms of skills and through activities, each child can use different tools according to their own interests to observe their own and their peers' fingerprints, discover the mysteries, and stimulate children's desire to explore. desire.
Activity goals
1. By studying fingerprints, children can learn the methods of scientific inquiry and improve their observation and hands-on practical abilities.
2. Experience the joy of observation and discovery, and cultivate children’s awareness of cooperation
3. Guide children to understand the three basic types of fingerprints (skirt-shaped, bow-shaped, and bucket-shaped) and realize that Uniqueness of fingerprints.
Key points and difficulties
Difficulty points: Understand the three basic types of fingerprints (skirt-shaped, bow-shaped, bucket-shaped),
Key points: Recognize the uniqueness of fingerprints.
Activity preparation
1. Preliminary experience: Children have learned relevant fingerprint knowledge through cartoons and stories, and know that there are fingerprints on their hands and that fingerprints are different; they have preliminary Observation ability, ability to use magnifying glass and other tools for observation, and ability to use comparative methods to observe and analyze things.
2. "Black Cat Sheriff" video, three types of fingerprint pictures
3. Transparent tape, ink pad, 6B pencil, and watercolor pen each.
Activity process
1. Finding fingerprints
1. Children watch video clips of the cartoon "Black Cat Sheriff".
2. Ask the children: After watching the cartoon, do you know what Sheriff Black Cat uses to find the bad guys? (Fingerprints) stimulate children's interest in studying fingerprints.
2. Preliminary observation of fingerprints
1. Children are free to choose the tools provided by teachers for observation, and guide children to see what their own fingerprints look like. You can use the tools provided by the teacher to make observations.
2. Questions: (1) Where are our fingerprints?
(2) "Are the fingerprints on each of your fingers the same?"
(3) Please use a magnifying glass to see what your fingerprints look like. Ask children to observe with questions and find answers during the observation process.
3. Observe the fingerprint types
a. The teacher shows the fingerprint pictures and guides the children to observe the fingerprint types (Teacher: "The teacher found two fingerprint friends for the children. Now let's do it together." Let’s get to know them! Children, look at what these two fingerprints look like.")
b. The teacher names the fingerprints and shows the word cards.
Teacher: "These fingerprints are the same as those of the children. It has a nice name"
Bow pattern - Features: Its center is like a curved bow and arrow;
Kei pattern - Features: Its center is like a A small whirlpool (or a small snail).
3. Fingerprint rubbing
The teacher encourages each child to use prepared items to rub fingerprints in various ways, and instructs the children to try various methods on white paper first. method, and then use the fastest and clearest method to rub fingerprints, and guide the children to compare the methods of rubbing fingerprints.
4. Successful communication.
1. Teachers and children *** share various methods of rubbing fingerprints.
2. Ask the children to explain their fingerprint rubbings to everyone, and encourage the children to speak boldly.
[Activity extension]
1. Make fingerprint paintings. Guide children to boldly imagine adding on their fingerprints to turn them into an interesting painting.
2. Parent-child activities: print the fingerprints of parents and establish a "family fingerprint file".
Activity Reflection
In the selection of activities, I chose "fingerprints" as the exploration object of the entire activity. This activity object is both familiar and certain to the children. The strangeness allows children to discover their own mysteries and stimulate their desire to explore and operate. At the same time, in terms of goal design, I set the goal in the process of experiencing operations, discovery, and exploration, encouraging children to boldly explore and find results, and experience the experience through a series of independent operations between themselves and their peers. The joy of collective learning. In the teaching process, I have the educational concept of "striving to form a cooperative and inquiry-based teacher-child interactive relationship during activities." In addition to influencing the children with full emotions during the activities, I also design various "problem situations" to let the children Observe with purpose and solve problems in the process of observation. In order to guide and help children to think and explore, and fully mobilize their enthusiasm for learning, throughout the entire activity, I mainly used teaching methods such as observation, recording, experience communication, demonstration, and operation throughout the entire activity. In order to allow the children to gradually and deeply understand fingerprints through the guidance and help of teachers, I organized this activity in an interlocking and layer-by-layer method to better achieve the goal. Scientific and interesting fingerprint lesson plan for large classes 2

2. Use a magnifying glass to carefully look at your fingerprints, and use plasticine and putty to leave your fingerprints.
3. Compare and see the difference between your own fingerprints and those of others, recognize the three types of fingerprints, and learn to identify your own finger type.
4. Think about whether the fingerprints printed by small hands on different materials are the same? Where else can fingerprints be left?
5. At the end of the exploration, try using Use a brush dipped in a small amount of paint to apply on your fingers to make a print, then use a gel pen to add appropriate modifications and processing, and enjoy the interesting fingerprint paintings together.
Activity extension:
1. Find places in life where fingerprints are likely to be left.
2. Ask parents or teachers to tell children stories about the uses of fingerprints.
Science Paradise
Fingerprints are the raised lines on the skin of your fingers. Fingerprints begin to appear in the fetus at three or four months, and are formed around six months. Fingerprints can increase friction when your hands touch objects. Although everyone has fingerprints, they are all different. From the basic line shape, fingerprints can be divided into three types: bucket-shaped patterns, bow-shaped patterns, and skip-shaped patterns. The fingerprints of different races are very different. It is said that no two people with exactly the same fingerprints have been found among the six billion people in the world! Therefore, each person's fingerprints are unique. Accordingly, it can be widely used in attendance, detection, and confidentiality systems. Scientific and interesting fingerprint lesson plan for large classes 3
Preschool knowledge review:
1. Types of fingerprints
2. Functions of fingerprints
Enhancement Friction can help solve crimes. It is widely used in high technology such as fingerprint locks, and can also be used in art such as fingerprint paintings.
Activity goals:
1. Understand the two types of fingerprints and their unique functions.
2. Be interested in exploring the mysteries of the human body.
Activity preparation:
Advertising video, magnifying glass, record sheet, ink pad.
Activity process:
1. Introduction: Watch the "Fingerprint Lock" advertisement
"Today the teacher brought an advertisement, please take a look at what they said in the advertisement What have you done there? ”
2. Observe fingerprints and understand the two types of fingerprints
1. “Where are your fingerprints? Please take a look. "Do your fingerprints look the same?" (Some friends said that the circles on the fingerprints are too dense and cannot be seen clearly. What can we use to see them?)
2. Children use a magnifying glass to observe fingerprints and then tell the story.
3. (Show your fingerprints) Show the whorl pattern, "What does this look like? This fingerprint that looks like large and small dimples is a whorl pattern."
( Show the hoof pattern) "What does this look like? This fingerprint is like a small horse's hoof, some pointing to the left and some to the right. It is called a hoof pattern."
Summary: We just observed our own fingerprints , we know that fingerprints can be divided into two types, scroll patterns are like small dimples, and hoof patterns look like small horseshoes.
3. Consolidate the operation and know the two types of fingerprints
1. "We got to know our fingerprint friends all at once. Then you know how many scroll patterns the teacher's fingerprints have. How many hoof-shaped patterns are there?"
2. "Do you want to know how many whorls and hoof-shaped patterns you have on your little hands? Now ask the children to observe them and record them." .
3. Children’s observation records, showing individual children’s operations and understanding their fingerprints.
4. "Just now, our children all printed their own fingerprints. The teacher has a question. Do you think everyone's fingerprints look the same?"
4. Understand fingerprints The use of fingerprints
“The children are right. Our fingerprints are all different and unique. Do you know what you can do with fingerprints?”
“Fingerprints are so impressive. Can you help the policeman solve the case? ”
V. Ending
“In addition to fingerprints, do you know what other patterns are different?”
p>
Summary: "The fingerprints on everyone's body are different. This is the unique password of each of our bodies. After you go home today, you can compare it with your parents to see if these lines are all different. Okay? Scientific and interesting fingerprint lesson plan for large classes 4
Activity goals:
1. Through this activity, initially stimulate children’s interest in exploring the mysteries of the human body.
< p> 2. Cultivate children's observation and comparison ability (understanding fingerprints and discovering the uniqueness of fingerprints through independent exploration), oral expression ability (telling the fingerprints they observed in complete language), and understanding ability. < p> 3. Preliminarily understand that fingerprints are generally divided into three types: bucket-shaped patterns, bucket-shaped patterns and arcuate patterns, and initially understand the uniqueness of fingerprints and their applications4. Cultivate children's curiosity about things. Be willing to boldly explore and experiment.
5. Be willing to cooperate with peers to experience the joy of the game.
Key points and difficulties of the activity:
1. Key points: through operation. Explore and understand the three types of fingerprints - bucket-shaped patterns, bucket-shaped patterns, and bow-shaped patterns (operating exploration method, game consolidation method, and contact yourself method)
2. Difficulty: Preliminary understanding of the uniqueness of fingerprints - the world. There are no fingerprints that look exactly the same (observation and comparison method)
Activity preparation:
Knowledge preparation: Children have certain knowledge about where fingerprints are and how they look different. Understand the ink pad, know its usage, and know how to clean it quickly with wet wipes (prepare the ink pad in advance)
Material preparation: Import advertisements, ink pad (6 boxes) and white paper ( Stick it on the table, draw a fingerprint record sheet for the left and right hands), three types of fingerprints (A4 paper), pictures of where the fingerprints are, courseware and videos on fingerprint effects, one lipstick, one wet wipe for each person (put in the center of the table), in advance Take photos of each child's 10 fingerprints (the names of the children should be on the paper).
Activity form:
Collective, individual
Activity process:
1. Introduction: watch the "fingerprint lock advertisement" to stimulate interest . (3 points)
Introduction: Hey, dear babies, hello! Today the teacher brought an advertisement shot by another kindergarten child. Please take a look at what they did in the advertisement. What?
Questions:
1. Children, can anyone tell me how the child inside opened the door? (With fingers)
2. The other two children imitated him to use their fingers to open the door. Did they open it? (No) Who knows why?
2. Expand:
1. Fingerprint recognition , game consolidation. (17 points) (Key points)
(1) Understand fingerprints. (9 points)
Transition: Well, the children’s answers are all different. I believe that when our activity is over, you will know why! Well... Then our fingerprints are in Where? (On the hand) Yes, to be precise, it is on the belly of the finger (show the courseware and clearly show the location of the fingerprint.) (If a child asks: There are also fingerprints on the palm, explain it as "handprint".) Your fingerprint Where is it? Stretch out and take a look.
Question: Can you please see if your fingerprints look the same? (Ask a child to say "can't see clearly".)
Introduction: Oh, one child said fingerprints The circles are too dense and cannot be seen clearly, so we have to think of a good way to solve this problem.
Question: Ask the children to look at the materials on the table. Who can use these materials to think of a good way to help everyone? (If the child mentions it, the teacher can promptly ask him to come to the front to demonstrate how to print fingerprints. , commented, "This method is very good, very convenient, and easy to distinguish which finger's fingerprint it is. You are really a child who loves to use your brain. You have helped everyone, great!")
Make a request : After pressing the ink pad, please put your fingerprints on the corresponding fingerprints of the left and right hands. When you have pressed all the fingerprints on one hand, please clean it with a wet wipe, and then print on the other hand. Okay, the little chair gently turns to the small table. Let's see how fast and quiet the child's operation is. Ready: start. (Children operate "printing fingerprints", and the teacher guides on tour.)
After the operation, ask: Please see if your fingerprints look the same? (Not the same) Tell me, what are your fingerprints? What does it look like?
Bucket pattern - small: circle and circle. The teacher operates the computer and shows the "bucket pattern".
Question: Children, take a look, what do these circles of fingerprints look like? (Children have really rich imaginations)
Summary: Circles like this The circle of fingerprints is called "bucket pattern". Please tell me again.
Skip-shaped pattern - small: like a slide. The teacher operates the computer and displays the "skip pattern".
Question: Children, take a look, what does this fingerprint look like?
Summary: A fingerprint like this that looks like a slide and a path is called a "skirt-shaped pattern." Please tell me again.
Please carefully observe whether your fingerprints have any other appearance besides these two? (The teacher knows that the fingerprint of one finger of Jing Huilin looks like this, like a small hill. Show "Arcuate pattern" picture. ) Such fingerprints are called arcuate patterns.
Summary: Children, through your observations just now, you have discovered that people’s fingerprints are generally divided into three types: bucket-shaped patterns, skip-shaped patterns, and bow-shaped patterns. The bucket-shaped pattern is like a set of ovals; the skip-shaped pattern is like a slide tilted to one side; the bow-shaped pattern is like an undulating hill. Generally, our fingerprints have more "bucket-shaped patterns and skip-shaped patterns", while there are very few arcuate patterns, generally only accounting for 2.5%, which means that there are only 2 or 3 arcuate patterns in 100 fingerprints!
( 2) Game consolidation. (3 points)
Transitional language: You are awesome. You have made friends with fingerprints all of a sudden. Let's play a fun game - "See who reacts faster."
How to play the game: Invite ten children to come forward each time and listen to the teacher's instructions to "grab" their fingerprints. For example: Children, get ready, let’s see who has the fastest response! (Door-shaped pattern) Practice all three types, and all the children will be divided into three groups to play the game.
(3) Know your fingerprints. (Infiltration Mathematics) (5 points)
Transition language: Just now, the children found the bucket-shaped pattern, the skip-shaped pattern and the bow-shaped pattern in a happy game. It’s really good! Then do you know your own How many bucket-shaped patterns, how many skip-shaped patterns, and how many bow-shaped patterns are there among the 10 fingerprints on your little hand? Then let us observe carefully and count them! Okay, let’s ask the children to count them first. How many bucket-shaped patterns are there in your 10 fingerprints? You must observe carefully and patiently! Come on! (Young Mathematics, Division Tour Instructor)
Question: Who wants to tell me, through you Observation, how many bucket-shaped patterns do you have? (7)
Yeah, there are quite a lot of them! Let’s take a look, does XXX have 7 bucket-shaped patterns? (Show the prepared fingerprint photos on the big screen.) Invite the children to be the referee to see if their observations are correct. (Invite three children to find three types of fingerprints respectively.)
Summary: Through the observation of the children just now, we all know our own fingerprints, which is great! Then I have a question, what do you think? Do each of us have exactly the same fingerprints? (Ask a preset question)
2. Compare fingerprints and understand their uniqueness. (3 points)
Question: Who wants to share your opinion? (Quickly ask a few more children to speak, the teacher will not comment.)
Introductory words: Children’s Everyone has different opinions. I know you have brought your parents’ fingerprints with you, so let’s first compare our own fingerprints with those of our parents to see if there are any fingerprints that look the same? Then compare with the children around you. Compare, are there the same fingerprints?
Question: Who has the results? Who wants to tell us the results of the comparison?
Summary: Each of us has unique fingerprints. Yes, just like our looks, although we all have eyes, noses and mouths, no one looks the same. Although our fingerprints only have three types: bucket-shaped, skip-shaped, and bow-shaped, no one’s fingerprints are the same! Children, you Do you know?
3. Expand knowledge and understand the application of fingerprints. (5 points)
Transition language: Since our fingerprints have unique characteristics, what do you think people can do with them? (Children can answer freely. Teacher: Well, you are really smart and can learn By using it, I learned about the secret of the child who just used his fingerprint to unlock the door; ah, you know a lot; how did you know?) Regarding the small "fingerprint", people have invented many strange ideas by using its characteristics. Wonderful idea, let’s take a look together! (Play courseware: fingerprint lock, fingerprint payment, fingerprint mobile phone, fingerprint car, fingerprint computer, fingerprint solving crime...)
Summary: These are the ways that people use fingerprint to solve crimes. Isn’t it great to use your own wisdom to use some technological products made by science to facilitate people’s lives? Do you know? Although fingerprints are small, they can also diagnose diseases. In the theory of traditional Chinese medicine, it is particularly effective in diagnosing children, for example: If the color of your fingerprints becomes lighter, it means that your body has become weak and you have begun to suffer from malnutrition; if your fingerprints turn bright red, it means you are in the early stages of colds, fevers, coughs and other diseases; if your fingerprints turn purple-red, then Your symptoms may develop into high fever, cough and asthma, bronchopneumonia and other diseases. Isn’t it magical! If you want to know more about the mysteries of tiny fingerprints, wait until you have the opportunity to ask your parents to take you to the “Chinese Fingerprint Museum” in Nanjing!
3. Ending: (2 points)
Transition language: Hey, the teacher wants to ask another question. In addition to fingerprints, people’s bodies are different. Do you know what other lines are different?
Younger: Palm prints, sole prints, toe prints...
Teacher: Teacher I also know one thing, that is "lip lines", which are the lines on our lips. Do you believe it? Well, let Teacher Yang and Teacher Liu put on lipstick and print two beautiful lip lines. Take a look!
The teacher prints lip lines... (to increase the happy atmosphere.
)
Summary: In fact, fingerprints, palm prints, sole prints, toe prints, lip prints, etc. are all different on the human body. These are the unique passwords of each of our bodies. I hope I The children in this class will be able to grow into scientists in the future and explore more mysteries of the human body! Then after we go home today, we can compare with our parents to see if these lines are all different! Okay?
Reflection on the activity:
Generally speaking, the design and preparation of this activity was quite careful, but after the class, I had some new ideas:
1. Import of activities.
In the introduction part, my original introduction was relatively plain, "Today the teacher brought an advertisement shot by children in another kindergarten. Please take a look at what they did in the advertisement?" to stimulate children's enthusiasm. Not interested. If I design it as: Question - children, what is this? (The teacher stretches out his finger to ask the children, and the children answer impromptu.) Such questions and doubts can make children think and speak boldly, because no one can I don’t know what the teacher wants to say about "finger". Such a question can also be consistent with the link in "Introducing the video", which can not only stimulate the interest of the children, but also cleverly combine with the video!
2. Children operate the "printing fingerprints" section.
Because this is a scientific activity, children’s operation and exploration are indispensable; and because the principle of one-to-one cannot be applied, I considered that “content in the field of mathematics” can be integrated in the exploration session, but I just They blindly thought of "the indispensable and integrated areas of operation and exploration", but did not take into account the age characteristics of children in a timely manner. Therefore, the process of printing "fingerprints" seemed very protracted, and not only did it take a long time, but the effect was not very good. Well, there are many children whose fingerprints are not very clear, which also leads to a disconnect in the subsequent counting process. It can be seen that it is not appropriate to let children print their own fingerprints. It is better to let children use a magnifying glass to visually observe their fingerprints, and then record the observations on the record sheet. This may save time and at the same time make people feel that this lesson is scientific, operational, and exploratory. , a series of integrated activities to show a shining side.
3. Ignore the ability of children in the upper class to already know how to read.
In the process of understanding fingerprints, I originally wanted to ask children to name three different fingerprints based on their appearance, so as to stimulate children's imagination. As a result, when the fingerprint picture was shown, the name of the fingerprint was written below. Before the children had time to diverge their thinking, their thoughts were solidified by the "correct" name of the fingerprint. Not only did they not show the brilliance of "diverting children's imagination", It is counterproductive and seems that the teacher is not sensitive enough!
In short, after reflection on this activity, I feel that there are many deficiencies and areas for improvement. I will continue to improve this activity in the future and Try teaching! Scientific and interesting fingerprint lesson plan 5 for large classes
Purpose of the activity:
1. Cultivate children’s interest in exploring themselves
2. Cultivate children’s detailed observation ability.
3. Guide children to know that everyone’s fingerprints are different and there are no two identical fingerprints in the world.
Activity preparation:
1. Each person has a red ink pad, pencil lead powder, and some rags.
2. One set of operational materials for children per person: (1) Two hands made of white cardboard. (2) There is an operation sheet for the apple tree.
3. Four magnifying glasses, several glasses, mineral water bottles, and beverage bottles.
Activity process:
1. Tell the children a story about fingerprints solving crimes to arouse their interest in observing fingerprints.
2. Print fingerprints:
1. Let the children dip one finger in red ink pad and print their fingerprints on the hand made of white cardboard (please make sure the children correspond to each other) , ask the children to talk about their findings.
2. Observe fingerprints:
(1) Guide children to use a magnifying glass to observe their fingerprints and fingerprints on paper, and talk about what their fingerprints look like? What is it like?
(2) Guide children to observe each other’s fingerprints and talk about the differences between each person’s fingerprints.
3. Understand the function of fingerprints:
1. The teacher shows two typical fingerprints and guides the children to observe their differences and find the characteristics of their own fingerprints.
Teacher’s summary: Everyone’s fingerprints are different. There are no two identical fingerprints in the world, and fingerprints never change, so they can be used to identify people.
2. Demonstration:
(1) Touch glasses, beverage bottles, mineral water bottles, etc. with your fingers, and ask children to talk about any changes. (No change at all)
(2) Evenly spread the powder from the pencil lead to the areas touched by your fingers, blow the excess pencil lead powder, and ask the children to talk about their findings. . (A clear fingerprint appears)
Teacher summary: When our fingers come into contact with objects, fingerprints will be left.
Teacher asked: In what ways are fingerprints left on objects helpful? (The police officer can use the fingerprints left by the criminal as evidence to catch the criminal)
(3) What else is it used for? Teachers show pictures and explain technological products related to fingerprints to broaden children's horizons.
(4) Teacher asked: What else has some texture like fingerprints?
IV. Fingerprint printing
1. Guide the children to dip the remaining nine fingers into ink pad and print on the other nine fingers, which should correspond to each other.
2. Guide children to print their fingerprints on the small apples of the apple tree to make a fingerprint tree.
