Teaching plan of large class science open class

Teaching plan for 5 large classes of science open class

As a selfless and dedicated people's teacher, teaching plans should always be prepared, which is the general organizational program and action plan of teaching activities. So how to write the teaching plan for the large class science open class? The following is the teaching plan for the large class science open class that I have compiled for you. I hope you like it!

Science Open Class in Large Classes 1 Selected Teaching Plan of Activity Objectives

1, let children explore shadows and gain specific experience about the formation and change of shadows.

2. Stimulate children's interest and curiosity in exploring shadow phenomena.

Activities to be prepared

Pictures of light source and hand shadow of flashlight or slide projector.

Activity process

1, to stimulate children's interest in shadows.

Teacher: Have you ever seen a shadow, little friend? When will there be shadows?

Child: When sunlight, electric lights and car lights shine on us, there will be shadows.

Teacher: Is there anything with shadows?

Children: trees, houses, etc. There are shadows.

Teacher: Why is there a shadow?

Let the children discuss and guess, and do experiments with a slide projector or flashlight. Let the children know that there is a shadow because the object blocks the light.

2. Play hand shadow games.

The teacher demonstrated making hand shadows. Let the children guess what this is and let them learn to do hand shadow. Please watch all kinds of hand shadow pictures in the courseware to let the children know that different postures will form different shadows under the light.

3. Guide children to observe the shadows and changes of objects.

Let children look for shadows outdoors, draw shadows and observe the differences and changes of shadows.

Selected teaching plans for the second activity goal of large class science open class

1, through playing poker, encourage children to boldly find ways to make poker stand up.

2, through the operation, understand the simple mechanics principle.

3. Learn to record the experimental results and be willing to express your thoughts in the group.

4. Willing to play games with peers and experience the fun of the game.

5. Cultivate mutual comity and learn the ability of division of labor and cooperation through experiments.

Activities to be prepared

1, there are 20 playing cards.

2, a piece of recording paper, pen hand.

Activity process

Introduce the topic first.

Teacher: What do you think this is, children? What are playing cards for? Today, the teacher will invite children to play a new game with playing cards.

Second, the children explore how to stand on the table with two playing cards.

Teacher: The teacher put two playing cards on each child's desk. Go and have a try and see if you can make the playing cards stand on the table. Then write down your method on paper and tell you later.

1, the child tries for the first time.

2. Communicate after trying.

(1) How to make playing cards stand on the table? Please show the children the recording paper and explain the demonstration.

(2) Why can this method make playing cards stand on the table?

(3) I just saw a few children use this method to make playing cards stand up, and then they fell down. What happened?

(4) Are there any different methods?

What's the difference between his method and that just now?

3. The child tries for the second time.

Just now, the children came up with several ways to make playing cards stand up. Now the teacher asks the children to try all these methods. Later, you can tell us which method can make the playing cards stand on the table most stably.

4. Communicate after trying.

(1) Which of these methods do you think can make playing cards stand on the table most stably?

(2) Why?

Third, guide the children to comprehensively use the previous methods to base the playing cards higher.

1, Teacher: Just now we came up with different ways to make playing cards stand up, and we also discussed which way can make playing cards stand up more stably. Now the teacher has prepared 20 cards for each child. What shall we do? The teacher will let you build a small house with these playing cards to see whose house is tall and strong. Later, please also record the method of building a house on paper.

2. Children try.

Please bring your own recording paper to communicate with others.

(1) Communication construction methods are different.

(2) Did you encounter any difficulties in the communication just now and how did you solve them?

4. Collective communication.

(1) Teacher: Who will introduce the small house you built? The teacher will compare the photos taken in advance with the children's recording paper.

(2) Tell your children about your own recording paper and how to build a house.

(3) Did you have any difficulty in building a house just now? How did you solve it? Who has a better way to help him solve this problem?

Extended activity

Just now, the children built it well. In the future, let's go to the classroom to design drawings, build a taller house and put more playing cards, shall we?

Teaching reflection

After this scientific exploration, I realized more deeply that children's wisdom is immeasurable. Before starting this activity, I was always worried that my children could find a way to make the playing cards stand up. If there is no inspiration, then my activities will be difficult to continue.

But when they stood up with a card, they came up with many ways. Although it is difficult for children to stand tall and steady with playing cards, they have always had a good interest in exploration, and finally they are still wanting more. In this activity, children also have fun in game activities. The whole activity was well organized, and one link after another was clear and smooth.

Of course, I also made mistakes in this activity, and the teacher's guidance is the key, but when the child stood up with a card and came up with many methods, I didn't guide enough here and didn't find more highlights for the child. The problem of cooperative combination was not raised, which led some children to combine cards instead of cooperating. This also sounded the alarm for my future activities. I must consider all aspects when designing teaching activities, imagine all possible situations before class, and pay more attention to guiding children, so that class can be more leisurely.

Three-strap schoolbag with selected teaching plans for large science classes.

Design intent:

Activity is a distinctive curriculum organization, which emphasizes the value of activity, pays attention to the process experience of activity, and takes changing children's learning style as a breakthrough to optimize the way of teaching and learning. These activities are based on children's life experiences. Near graduation, the topic that children discuss most is small schoolbags. In the choice of schoolbags, they often pay attention to styles, famous brands, colors and functions. However, it ignores the width of the shoulder strap of the schoolbag and the protective effect of the small schoolbag on the body. Therefore, teaching activities-carrying a small schoolbag, starting from the self-protection of children's bodies, are combined with scientific knowledge: the pressure is constant, and the greater the stress area, the less the pressure, which emphasizes the process of children's experience and inquiry. Scientific knowledge can be transmitted to children in a simple and easy-to-understand way and effectively used in life, further stimulating children's interest in observation and inquiry.

Activity objectives:

1. Feel the different experiences brought by schoolbags with different widths and narrow shoulder straps.

2. Actively explore and cooperate with peers to complete the task.

Focus: Feel the different experiences brought by schoolbags with different widths and narrow shoulder straps.

Difficulty: I found a secret that a schoolbag with wide shoulder straps is easier to carry than a schoolbag with narrow shoulder straps.

Activity preparation:

Materials: Several schoolbags and books with different shoulder straps.

Small experiment: two sponges and a small chair.

Activity flow:

First, different schoolbags-looking for differences

Lead to the topic:

1. These are schoolbags for primary school students. Are they the same?

2. Talk about their differences.

3. Summary: Small schoolbag, with so many changes, you are sure to find your favorite small schoolbag.

Second, carry a small schoolbag-experience feelings and discover secrets.

1. Just now you found that the shoulder strap of the schoolbag is wide or narrow. If you put as many books in these two schoolbags and carry them on our shoulders, which one will be more comfortable and relaxed?

Please cooperate with both of you to finish a task together.

Tip: Two people work together-five books in the schoolbag-and two people take turns carrying small schoolbags and walk around slowly.

3. Children cooperate to explore and communicate with each other.

4. communicate and share? Tell me how you feel. Which schoolbag is more comfortable to carry?

What do you think might be the reason?

Let's watch a little experiment together. Sponges took the place of our shoulders. What happened when a small schoolbag was carried on our shoulders? What did you find?

Summary:

Narrow-shouldered schoolbags will carve deep marks on our shoulders, which will make us feel pain and discomfort when we carry them back, while wide-shouldered schoolbags will not pinch our shoulders, which will make us feel comfortable and relaxed when we carry them back. Through a small experiment, we know that a schoolbag with wide shoulder straps can protect our shoulders and make our backs more comfortable. Therefore, when we choose a small schoolbag in the future, we should try to choose a schoolbag with a wider shoulder strap.

Third, transfer use-try to use it to expand life experience 1. This is a schoolbag with thin shoulder straps. Is there any good way to make it wider and make your shoulders more comfortable and relaxed?

2. Show a schoolbag with shoulder straps. Small wide shoulder straps can make our backs more comfortable.

There are still some such good methods in our life. Let's take a look at them together. Please think about where it has widened. What's the use of widening?

Activity reflection:

Teaching activities are carried out one after another in a relaxed and orderly process, and children learn happily and easily. The design of teaching links serves the goal of teaching activities, and the effectiveness of the activities is reflected. Activities focus on children's experience and exploration; Pay attention to the demonstration of scientific experiments, so that children can be demonstrated in real-time and effective observation to achieve a kind of * * * knowledge; Pay attention to the combination of scientific truth and life, and pass on scientific knowledge to children in a simple and life-oriented way. The extension of activities will make children pay more attention to the things around their lives and find more such good methods. The combination of science and life is more meaningful to teaching.

Activity evaluation:

These activities are based on children's lives. In this process, we pay attention to children's exploration and experience, let children fully express their experiences and feelings, and convey scientific principles to children in a simple and life-oriented way, so that children can learn and gain experience in happiness.

Teaching objectives of 4 teaching plans selection in the open class of large science classes;

1, through children's own observation of experimental phenomena, cultivate children's orderly and patient good observation habits and keen observation ability.

2. Cultivate children's interest in understanding and exploring the scientific principles contained in common things in life.

3. Cultivate children's ability to solve problems through their own operations.

Teaching preparation:

Prodigy computer software, bridge exhibition, pen and paper.

Teaching process:

First, arouse children's interest in the form of stories:

There is a small ditch in front of the bear's house. It's worried about what to do to cross the other side. Children, can you help bear find a way? Little bear's good friend, the clever monkey, also helped him think of a way. Let's hear what it is. Is it what we think?

Second, ask questions while watching prodigy software:

1. Where do smart monkeys and bears come from? What bridge do you see? What did ancient people use to build bridges? Does bear like it? Why?

2. Which bridge did the clever monkey and bear come to? What was Zhao Zhouqiao built of? What is its shape? What's the difference between Zhao Zhouqiao and Zhu Qiao?

3. What bridge did they see when they came to modern times? What is the steel suspension bridge made of? What's special about reinforced suspension bridge in structure? What is the function of reinforced suspension bridge? Which steel suspension bridges have you seen now?

4. After seeing the steel suspension bridge, what bridge did they see? Where is the modern overpass built? What is it made of? What role does it play in traffic? Where do you see the modern overpass?

Besides the ancient bamboo bridge, Zhao Zhouqiao and modern steel suspension bridge and overpass introduced by the clever monkey, what other bridges have you seen?

6. Let's get into the computer and look at some bridges with different materials and different uses.

We have seen so many bridges, which one do you like best? Why?

Bell wants to build a bridge now. I want to ask children to be a small bridge designer and help bear design a bridge, ok?

Five, children design bridges.

6. Ask some children to introduce his design works to everyone, and finally give them to the bear.

Selected teaching plans of 5 activities in large class science open class

1, let children know the basic properties of water: colorless, odorless, transparent and flowing.

2. Know that water is the source of life and understand the use of water.

3. Stimulate children's interest in exploring water, know how to save water and protect water resources.

Activities to be prepared

Some plastic cups, two kinds of pigments, two stones, salt, sugar, a washbasin, a tape recorder and a tape.

Activity process

First, guess the import

If you don't wash it, it won't get dirty. The more you wash, the dirtier you get. Flowers and trees need it. Everyone needs health, but they can't do without it. (natural water)

Second, briefly introduce the three states of water.

Cold water freezes in winter, which is the solid state of water. In summer, rain is the liquid state of water, and the gas emitted by boiling water is the gaseous state of water. Then, like a magician, water turns into ice, rain and gas. Isn't it interesting? Do you want to know more about water? Ok, let's study it and see what's different about water.

Third, explore the nature of water.

1, water is colorless.

Experiment: Fill three cups with half a cup of clear water, and add different pigments to two of them, and the water will immediately turn into different colors, so that children can understand that water is colorless, but what color it will become when any pigments are added.

2. Water has no taste.

Experiment: Let the children smell and taste the clear water to judge whether it has a taste, then add sugar and salt to the clear water and let the children taste it. According to the children's personal experience, I sum up that water has no taste.

3. Water is transparent.

Experiment: Put one stone in a colored cup and the other in clear water, let the children observe and compare which cup can see the stone clearly and which cup can't, and finally come to the conclusion that the water is transparent.

4. The water is flowing.

Experiment: Make a sink out of a beverage bottle, and connect a cup or basin below. Let the child observe how the water enters the cup or basin below, and the child will tell that it is flowing in, so that the water is flowing.

Fourth, discuss the use of water and educate children to save water.

After summarizing the nature of water, the teacher asked the children, "What can water be used for?" Let the children discuss and answer each other. Children will say according to their own life experience: water can be used for washing face, washing hair, washing feet, washing clothes, bathing and so on. Teachers can broaden their thinking and tell children that it can also put out fires, irrigate farmland and generate electricity. Let children know that water is very useful and human beings can't live without water, which leads to water conservation.

Let the children imagine what would happen to us without water. What will happen to the toilet? What happens when cooking? This will deepen the impression and let the children really save water.

The teacher asked the children, "What waste of water have you seen? How should we save water afterwards? " The children expressed their opinions, and the teacher summarized them.

Fifth, do the rhythm "The faucet doesn't cry" to end the activity in a relaxed and happy atmosphere.
