Scientific teaching should make full use of various educational resources widely existing in schools, families, society, nature, networks and various media. Science lesson plans for large classes can help science teachers in large classes to carry out science teaching in large classes better. Can you write a science lesson plan for a large class? Whether you are looking for or preparing to write "Teaching Plan for Preschool Science Teachers", I have collected relevant information below for your reference!

1 The color of the juice in class is given to the preschool science teacher.

Activity objectives:

1. During the activity, we will record experiments and classify similar fruits, thus forming a good habit of careful observation.

2. Experience the happiness of success and the happiness of helping others in activities.

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

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

5. Stimulate children's willingness to explore the fun of scientific experiments.

Activity preparation:

1, apples, pears, watermelons, oranges, oranges, grapes and other fruits.

2, all kinds of fruit pictures, color tags.

3. Give everyone an operation card (with some pictures of fruits on it), white cloth and glue stick.

Activity flow:

Show a letter first to arouse the child's interest in the experiment.

Teacher: Today, my little brother and sister in Class One sent a letter to our children in Class Two. What was written in the letter? Let's take a look! Wow! There are so many fruit cards and a writing paper. Look at what it says.

1. Read the letter: Hello, children in Class Two! We are children in a small class, and we really want to know what color the juice of various fruits is. We'd like you to help us tell us what color the juice of these fruits is, and is it the same color as the peel?

2. Discussion: What color is the juice? Is it the same as the peel?

3. What color is the juice of these fruits, and is it the same as their peels? Teacher Wang doesn't quite understand. Let's do a little experiment today to see what color the juice is, shall we?

Second, children experiment to understand the juice color of various fruits.

Teacher: Today, the teacher prepared all kinds of fruits, some white cloth, an experimental record sheet and some color codes for you. Please record the experimental results on the experimental platform with a colored pen when doing the experiment.

1. The children record the experimental results while doing the experiment, and the teacher tours to help the children with poor ability to record the experiment.

2. Please tell some children about the experimental process and records.

3. For controversial experimental results, teachers get correct results.

Third, the child experimented again and classified the fruits.

Teacher: The juice color of these fruits is the same as the peel color, and some are different from the peel color. So, which ones are the same color as the peel? Which ones are different from the peel color? Let's do another experiment together. While doing the experiment, we will classify the fruits, and put the juice with the same peel color and the fruit card together, but not the same.

1, children's experiment, sorting fruit cards.

2. Children tell the experimental results.

3. Send the card: Send the fruit card to the corresponding basket. The juice is put in one basket with the same color as the peel and in another basket with a different color.

4. The teacher summarizes the child's operation results and gives praise and encouragement.

Fourth, write back to the animal kindergarten and experience the happiness of helping others.

Teacher: We know the juice color of all kinds of fruits, but the younger brothers and sisters in the small class don't know it yet. Shall we write back and forth together and tell them the results of our experiment?

1. Record the experiment, fold it and put it in the envelope.

2. Pack the sorted fruit cards separately, write instructions and put them in envelopes.

Verb (abbreviation of verb) promotion activities:

1, teachers and students write back together.

2. Squeeze your own juice and taste it together.

Attached:

The colors of orange juice and orange peel are orange, orange and orange peel are orange, and kiwi fruit juice and orange peel are green. Apple skin is red, pear skin is yellow, grape skin is purple, and their juice is colorless. Watermelon skin is green and watermelon juice is red.

Children's science teacher's lesson plan 2 Blowing balloons in a bottle

Activity objectives:

1. The relationship between blowing a balloon in a bottle and the air pressure in the bottle is known through speculation and exploration.

2. Be able to record the experimental results truthfully and use language to express your findings boldly.

3. Experience the fun of scientific discovery and stimulate the desire to further explore other methods of blowing balloons with bottles.

Activity preparation:

1. There are several bottles and balloons of different sizes.

2. Six children's recording papers, several crying dolls and laughing dolls, and markers.

Key points and difficulties:

1. Explore the relationship between the balloon in the blowing bottle and the air pressure in the bottle by guessing.

2. Find problems and be able to explore records boldly.

Activity flow:

I. Import

1. The teacher shows balloons in the form of "magic" to stimulate children's interest in blowing balloons in bottles.

Two. Basic activities

1. The teacher asked two children to blow balloons in front of the group, fix the blown balloons and then ask questions.

Teacher's summary:

When blowing a balloon, stick your mouth to the balloon mouth, and blow hard to blow it up.

1. The teacher presented a small bottle in the form of exploring obstacles, stuffed the balloon into the bottle and asked the children to record their guesses.

Teacher: Can a balloon be blown up in a bottle?

Teenager: the children answered.

The teacher showed the recording paper and introduced (? Stands for conjecture, and "little hand" stands for experimental practice. )

1. Does the teacher let the children be there?

Guess the column and make your own guess record.

2. Take out the materials and let the children operate the experiment, and record the experimental results in the column of "Little Hands".

3. Teacher-child discussion.

4. Teacher's summary: It turns out that guessing alone is not necessarily right, and it is necessary to operate the experiment to draw a conclusion.

2. Explore the use of bottles of different sizes to blow balloons.

1. Bottles of different sizes are available. Have a guess.

Teacher: Balloons that used to be inflatable can be inflated now. Why can't it be inflated now?

Young: Children answer independently.

2. The child first records the guess, then carries on the experimental operation, records the form, and the teacher instructs.

3. The teacher discussed with the children, and the teacher asked several children to talk about his conclusion.

The teacher concluded: it doesn't matter whether the balloon in the bottle can be blown. What is the reason?

Children explore again, seeking the secret of success.

1. Stimulate children's desire for success

Teacher: What are the results of our two experiments? None of them succeeded, did they? Are you disappointed now? Don't worry, teacher. Here's a good idea.

2. Show the children's emoticons and explain the requirements.

Experimental requirements:

1. Try each bottle.

2. Take notes carefully

3. If you succeed, don't forget to look for the secret of the bottle baby and paste the corresponding expression.

4. Children's experimental operation and teacher's guidance.

5. Teacher-student discussion

Teacher: Who will talk about his findings?

Young: Children answer independently.

The teacher concluded: It turns out that a hole in the bottle can blow up the balloon.

Three. Conclusion part

1. Summarize the experimental results and improve the experience.

Guide the children to talk freely about the reasons, and the teacher summarizes the scientific experience.

Teacher: Why can a balloon be blown up in a bottle with a hole? Please talk about it.

Young: Independent answer.

2. Teacher's summary:

Teacher: So there is a scientific truth hidden here! Because the bottle is full of air, the balloon that becomes bigger gradually pushes the air out of the bottle through the small hole when blowing the balloon, and the air in the bottle without the small hole can't be discharged, so the balloon can't be blown up.

Four. Expansion of activities

Teacher: Today, we successfully inflated the balloon in the bottle by opening a small hole. Take a closer look at the record sheet. What column have we left blank? Teacher, give you a straw. Put it in a bottle and blow the balloon. I don't know if it will succeed. Let's go back to the classroom and experiment together! Say goodbye to the guest teacher and take the children out of the classroom.

The Secret of Rain by the Preschool Science Teacher

moving target

1. Guide children to try to do small experiments by themselves, so that children can initially feel some scientific phenomena such as "evaporation of water vapor" and "how rain is formed".

2. Understand the relationship between rain and human beings.

3. Stimulate children's interest in observing, discovering and exploring nature.

4. Make children interested in exploring natural phenomena.

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

Activities to be prepared

1. Puppet table, puppet rabbit, mother rabbit.

2. Alcohol lamps, beakers, glass pieces, glasses and matches.

3. Projector, the story "A Drop of Water Travel", related slides and tapes.

Activity process

First, the teacher put forward a puppet show and tried to ask questions. The teacher took the rabbit out to play with his mother rabbit. Suddenly it rained. Rabbit asked his mother, "Why does it rain in the sky?" The story leads to the topic and asks the question: "Children, do you know why it rains?"

Second, children do small experiments (children try for the first time, group activities)

1. The children lit the alcohol lamp and heated the water.

2. The teacher asked questions: Look carefully, what do you find?

3. Summary: When the water is hot, there will be water vapor, and the phenomenon that a lot of water vapor runs upward is called "evaporation".

4. Discussion: Have you seen the phenomenon of "evaporation"? (divergent thinking)

Third, observe the phenomenon that water vapor turns into small water droplets when it is cold.

1. Please touch it. Is the glass plate cold or hot?

2. Pour hot water into the cup and ask: What comes out of the cup? (water vapor)

3. What will happen if the cup is covered on the teacup? Why are there small drops of water on the glass? The experimental results show that water vapor will become small water droplets when it is cold.

Four, slide show (through intuitive teaching, focus on understanding the scientific phenomenon "why it rains")

1. The sun is a big fireball, it is like a strange stove. Clothes, handkerchiefs, rivers and water in the land are turned into steam by the sun. Where did all this steam go?

2. Ask the children to listen to an interesting story "The Journey of Little Water Drops" (combined with slides).

Please tell the little secret "Why is it raining in the sky" to Mother Rabbit and Little Rabbit.

5. Understand the relationship between rain and human beings

1. Let the children try to talk about the benefits of rain.

Let the children try to talk about the danger of rain.

3. Summarize the harm of the benefits of rain told by children, educate children to learn from the knowledge and skills of primary schools, grow up to be scientists, and let rain do more good things for mankind.
