Magical fingerprint lesson plan for large class science activities

Before teachers carry out teaching activities, they have to prepare lesson plans. With the help of lesson plans, they can improve the quality of teaching and achieve the expected teaching results. How to write a lesson plan? Below is a magical fingerprint lesson plan for large class science activities that I compiled for everyone. It is for reference only. Let’s take a look. Magic fingerprint lesson plan for large class science activities 1

1. Design intention

The purpose of early childhood science education is to cultivate children’s desire and spirit to explore. For children, science is a process - -It is the process by which they discover problems, ask questions, and verify problems. Through observation, I found that many children do not observe food attentively and carefully enough, so I designed this activity to guide children to discover the secrets of fingerprints through careful observation and comparison, and to cultivate children's love for science and the spirit of scientific exploration.

The "Outline" states: "The selection of educational content must not only suit the current level of children, but also be challenging; it must not only meet the actual needs of children, but also be conducive to their long-term development; both It is necessary to choose things and problems that children are interested in close to their lives, which will also help to expand children's experience and vision and the spirit of "experience". According to the requirements of the "Outline" and the age characteristics of the children in the top class, "fingerprints" are used as scientific education content for young children. During the activities, I provided a wealth of operational materials for the children. I reasonably positioned the key points and difficulties during the activity, and used methods such as intuitive operation and summary to encourage children to boldly communicate and share the process and results of exploration.

2. Teaching Objectives

It is pointed out in the new "Outline" that the contents of the five major areas penetrate each other and promote children's emotions, attitudes, abilities, knowledge, skills, etc. from different perspectives. Therefore, based on the age characteristics and actual situation of children, as well as the differences in children’s existing knowledge and experience, abilities, development levels and potential abilities, I have established goals in terms of cognition, ability and emotion, including independent expression. Components, but also have mutual integration, the goals are as follows:

Cognitive goal: discover the secrets of fingerprints through observation and comparison, understand the basic characteristics and functions of fingerprints; ability goal: compare various fingerprints through observation , and be able to tell the difference; Emotional goals: Be motivated to use your hands and brain, experience the joy of discovery, and develop the good habit of careful observation.

3. Key points and difficulties

(1) Key points: Understand the characteristics of fingerprints.

(2) Difficulty: Tell the difference of fingerprints through observation, and know the use of fingerprints.

In order to solve the key points and difficulties, during the activities, I provided the children with intuitive teaching aids and learning tools, while also creating a relaxed and happy environment for them, which was conducive to the completion of the teaching key points. and breakthroughs in difficult areas.

IV. Teaching and Learning Methods

(1) Teaching Methods Based on the goals and the actual situation of the children, I have adopted the following teaching methods:

Intuitive operation Method: At the beginning of the activity, introduce the topic through a fingerprint painting to give the children an intuitive understanding of fingerprints; at the same time, provide the children with ink pads and paper and let the children operate it by themselves, which will be more vivid; at the end of the activity, show the children Pictures of technological products related to fingerprints can also give children an intuitive understanding.

Summary and induction method: In the activity of "observing fingerprints", I divided the process into three steps. After each comparison, the teacher made a clear summary, so that the children can understand Have an overall understanding of the characteristics of fingerprints.

Environmental Creation Method: I end the activity with children creating fingerprint paintings, and guide the children to post their works in the gallery of the "Fingerprint Painting Exhibition". The creation of the "Fingerprint Painting Exhibition" will make the children more creative. desire.

(2) The whole activity of learning method is based on children. This activity mainly adopts the following learning method:

Observation method: The whole activity has always been about children learning through their own Draw conclusions based on observation.

Statistical method: When understanding fingerprint characteristics, I asked children to record and count their own fingerprint types to better consolidate.

5. Teaching preparation

(1) Space preparation: Divide the children into several groups and sit around the table. The teacher's operating station is arranged in the front. Layout of the "Fingerprint Exhibition" gallery.

(2) Item preparation: 1. A fingerprint print; 2. Some ink pads and white paper; 3. Magnifying glass (one for each child); 4. Twin fingerprints; 5. A physical projector Taiwan; 6. Glasses, pens, phones, etc.; 7. Pictures of technological products related to fingerprints; 8. Short stories about solving crimes.

6. Teaching process

(1) Show fingerprint prints to arouse children’s interest in fingerprints.

Teacher: Look, what is this? Do you know what this was painted with? (Fingerprints) It’s really interesting. Fingers can draw such beautiful pictures. Let’s do a fingerprint too, shall we?

(Let the children dip their fingers in ink pad to print their fingerprints on the paper, and give the children a large mirror) Analysis: Today’s topic is introduced through a beautiful fingerprint painting, and at the same time it stimulates the children’s interest and exploration desire.

(2) Recognize fingerprints and observe fingerprints.

1. Understand fingerprints.

Teacher: Please tell me, what did you find? (There are textures, lines, like circles...) Teacher: Children observe very carefully, do you know what it is? It has a nice name called "fingerprint".

2. Guide children to observe fingerprints, (1) compare their own fingerprints with those of their peers; Teacher: Look at each other, are the fingerprints of other children the same as your own?

Summary: The fingerprints of our companions are different from ours.

(2) Compare whether your own fingerprints are the same as those of your parents; Teacher: (Let the children take out the fingerprints of their parents and compare them with their own) The fingerprints of the little friends turned out to be the same as our own. No, we look a lot like our parents. Are their fingerprints the same as ours?

Summary: Mom and Dad’s fingerprints are different from ours.

(3) Compare the twins’ fingerprints to see if they are the same; Teacher: (Take out pictures of the twins’ fingerprints to guide the children to observe) Children all know that twins look very similar, basically exactly the same, so their Are the fingerprints the same?

Summary: The fingerprints of twins are also different.

(4) Teacher’s summary: Everyone’s fingerprint is different, and it is one of the characteristics of everyone.

Analysis: In the link of "Understanding Fingerprints and Observing Fingerprints", I adopted a hierarchical comparison method. First, I started with the children around me, then extended it to my own parents, and then another The "twins" that attract more attention, because I couldn't find live twins immediately, so I prepared pictures of the twins' fingerprints before the event. Through several levels of comparison and observation, children can more vividly understand the "distinctiveness" of fingerprints.

(3) Observing the types of fingerprints 1. Put the fingerprints of several children on the physical projector and guide the children to observe the types of fingerprints.

2. Find two common fingerprint types and name them respectively. (Bucket type, composed of many concentric circles, looks like a vortex in the water; dustpan type, the lines are like a dustpan, with one side open) 3. Teacher: Use a magnifying glass to look quickly, how many fingers do you have? It's bucket-shaped. How many fingers are dustpan-shaped? (Everyone counts the number of their own fingerprints to consolidate their understanding of the types of fingerprints).

Analysis: In this link, through the food projector, children can understand fingerprints more clearly and intuitively. Finally, let the children count and record their own fingerprints. This is a good consolidation method. During this process, the teacher should provide timely guidance and correction to help the children correctly understand and distinguish the types of fingerprints.

(4) Understand the function of fingerprints 1. Demonstrate using fingers dipped in ink pad to touch glasses, pens, phones and other objects one by one, and ask children to talk about what they find. When our fingers come into contact with objects, fingerprints will be left behind.

In what ways does this help? (The police officer can use the fingerprints left by the criminal as evidence to catch the criminal.) Tell a brief story about solving the case.

2. In addition to being helpful in solving crimes, what else are fingerprints used for?

The teacher showed pictures - technological products related to fingerprints to explain to the children, broadening their horizons.

(1) Fingerprint attendance machine (2) Optical fingerprint mouse (3) Fingerprint safe (4) Fingerprint lock analysis: In this link, the teacher should tell a short story about solving a crime, so as to not only attract children attention, and the understanding of the role of "fingerprints in solving crimes" will be deeper.

(5) Ending part:

Teacher: Fingerprints are really useful. Not only can they help the police solve cases, but they can also provide high-tech products to serve us and our lives. Increase insurance. Not only that, we just saw many beautiful pictures drawn with fingerprints. Do you want to give it a try and use your dexterous little hands to draw beautiful pictures and post them in our "Fingerprint Painting Exhibition" gallery.

Accompanied by the sound of music, the children happily created and ended this activity.

Analysis: Using fingerprint painting as the end of the activity not only allows children to take a break, but also integrates science and art activities during the creation process, which not only stimulates children's creativity, but also It can enable children to consolidate the shape and characteristics of fingerprints again.

7. Extension of the activity

Based on the age characteristics of the children and their own desire to explore, I designed the look of this activity as - "Let the children go back and check the information with their parents: Do the little animals have fingerprints? Do they have the same fingerprints? "This not only gives children an opportunity to continue exploring, but also allows them to better interact with their parents.

Activity goals

1. Understand the three types of fingerprints through observation and comparison. Basic characteristics and uses of fingerprints

2. Preliminarily understand the uniqueness of fingerprints, try to record fingerprints by "printing", and be able to tell the difference

3. Develop careful observation Good habits and experience the joy of discovery.

Key points and difficulties: Learn about the three types of fingerprints - bucket-shaped patterns, bucket-shaped patterns, and arcuate patterns. Understand the uniqueness of fingerprints - no one looks alike in the world. Touch the same fingerprints.

Activity preparation

1. Children have used dye to color or found fingerprints. 2. Fingerprint type PPT, white paper. And some ink pads, magnifying glasses (one for each hand), rags, wet wipes

Activity process

1. Introduction

Appreciate fingerprint paintings and stimulate children's awareness of fingerprints. Explore your interests.

Children, have you ever painted?

Today the teacher brought you a painting. Let’s take a look together. (The teacher shows the fingerprint painting) What’s different about this painting and the paintings we usually draw?

2. Classification of fingerprints

What are fingerprints? What? Fingerprints are patterns formed by convex skin on the ends of human fingers. Fingerprints can increase friction when the hand touches an object, making it easier to exert force and grasp the object. It is naturally formed during the process of human evolution. .

3. Guide children to observe fingerprints and understand the three types of fingerprints.

1. Guide children to guess whether your fingerprints are different from those of other children. Are the fingerprints the same? Are the fingerprints of each of your fingers the same? 2. Guide children to observe carefully and understand the three different types of fingerprints.

(1) Teacher. Explain and demonstrate how to print fingerprints clearly.

(2) Distribute materials, children perform hands-on operations, and teachers guide them

(3) Guide children to observe and communicate with fingerprints. Three types of fingerprints. (PPT)

Teacher’s summary: Everyone’s fingerprints are different. Scientists divide fingerprints into three major categories. The first type is called a bucket-shaped pattern, with a center like a small mark in the water. vortex. The second type is called a dustpan pattern, with the center tilted to the left or right, like a dustpan; the third type is called a bow pattern, with the center like a curved bow; isn't it amazing?

3. Guide children to observe their fingerprints and talk about what type their fingerprints are. (Guide children, "Some people have several types of fingerprints on their fingers)

IV. Application of fingerprints

Children, think about it, what are the uses of these fingerprints?

1. Fingerprints can help the police solve cases, because everyone’s fingerprints are different and are characteristic marks.

2. Fingerprint door locks, fingerprint ID cards, fingerprint sign-ins, fingerprint car locks, etc.

Teacher summary: Fingerprints are the lines formed by the bumpy skin at the ends of the fingers. Fingerprints can increase the friction of the fingers, so that things will not slip off easily.

Fingerprints are also the outlet of sweat glands, which can help us regulate body temperature. Everyone's fingerprints are different and generally remain unchanged throughout life. Fingerprints will become larger with age, but their shape will remain the same.

5. Appreciate and make fingerprint paintings

The teacher plays the PPT picture and asks the children to appreciate the fingerprint paintings.

Fingerprints are so useful. Not only can they help the police solve crimes, they can also draw very creative fingerprint paintings. Do you want to draw them?

Let’s use your dexterous little hands to draw beautiful fingerprint paintings.

Ask the children to go home and carefully observe their fingerprints, and look at each of your fingerprints. Which type is it. (Circles, triangles, and squares are represented respectively.) Count how many skip-shaped patterns, how many bow-shaped patterns, and how many bucket-shaped patterns you have.

Observe what your parents’ fingerprints look like. Are your fingerprints the same?

Activity summary

This activity was relatively successful overall due to sufficient preparation. Especially because the creation of this activity is not unilaterally designed by the teacher, but incorporates the independent choices of the children. It is a topic that can truly interest the children. After class, most children have a comprehensive grasp of the characteristics and uses of fingerprints.

Since this is a topic that the children themselves are interested in, the children are more actively prepared, and they are more enthusiastic about asking questions in class, and the teacher-child interaction is good. More importantly, they have their own thinking. In this activity, they are not only course participants, but also course designers. As a teacher, I also made corresponding changes to the lesson plan in a timely manner. However, this activity also has shortcomings. I did not fully consider the variables that may arise during the teaching process, such as the questions raised by young children about the fingerprints of twins. If I had not happened to prepare enlarged pictures of the twins’ fingerprints during the preparation, , when children ask questions, I can only explain the knowledge boringly, but cannot let them observe intuitively, then the effect of my lectures will be greatly reduced.

Due to time reasons, the final game and summary time were relatively hasty. Therefore, I think that in future course teaching, I should pay more attention to considering problems that may arise during the teaching process, fully prepare and strengthen time control.
