Primary school science 15 minutes on how to write lesson plans.

1 Consolidate 9 new words such as "black crow". Can write six words such as "Ke, Shi".

2. Read the text correctly and fluently. Recite the text. Through reading aloud, I realized the changing process of "crows are eager to find water-they can't drink water-they try to drink water-they drink water". Can speak sentences gradually.

Understand that when encountering difficulties, you should observe carefully and think seriously.

2. Teaching difficulties

On the basis of full reading, I realized that crows are smart and capable, and I was inspired by them.

Three. teaching process

(A) Review new words

Teacher: Children all like the story of crows drinking water. Yesterday, we learned the new words in this text. Hey, who has a good memory? (Review new words by name)

(2) Self-study the first paragraph.

Please turn to page 83.

(1) Teacher: The first paragraph is very simple. Now the teacher doesn't teach, let the children learn by themselves and see which child has strong skills and can read it with the help of pinyin.

Teacher: Who is skilled? What did you read in the first paragraph of self-study?

Health: A crow is thirsty and wants to find water to drink.

Teacher: It is said in the text that crows look for water everywhere. How about adding "everywhere"? (The crow looked for many places) Health: It means that the poor crow looked for many places, but couldn't find water. He is very worried.

Teacher: If you are this crow, what are you thinking at the moment? What did the crow see at this moment? Who can tell me?

Health 1: I will be very anxious and uncomfortable. "I want to drink water, I want to drink water."

Health 2: It's hard not to drink water. hey

Health 3: Who can tell me where there is water?

Guidance: The crow is so happy to see water in the bottle! But I can't drink it. What a hurry. Read the second sentence of the first part.

Teacher: Which group would like to send a representative to talk about why crows can't drink water? (Name two people) If something happens to the bottle, can the crow drink water? Please talk in the group.

Health 1: The bottle is not high, and crows can drink water.

Health 2: If the bottle mouth is big, crows can drink water.

Health 3: If there is more water in it, crows can drink water.

Let's read the first paragraph of the text again, paying attention to "everywhere, but what should I do?" (read together)

Teacher (summary): The child is really capable. The teacher didn't teach you, so you taught yourself the first lesson.

(3) Self-study the second and third paragraphs

(1) Teacher: Crows can't drink water. What shall we do? Let's help the crows. Please close the book and think about how to drink water.

Health 1: broken bottle.

Health 2: Put in sand and suck it through a straw.

Health 3: Turn the bottle upside down and drink the water inside.

……

Teacher: Children have many ideas. Now let's see what the crow thinks. The teacher still doesn't talk about the second and third sections of the text. Let the children learn by themselves and see if you understand.

Teacher: The crow picked up a pebble and put it in the bottle. What does the book say about the water in the bottle?

Health: The water in the bottle is rising gradually.

Teacher: Can you change "gradually" to "soon"?

The water in the bottle is (gradually) rising. Read it.

("gradually" means rising bit by bit, "soon" means rising all at once. Because putting a stone will raise it a little, put it one by one, so you can only use it slowly. ) "gradually" means slowly.

For example, "Spring is coming and the weather is getting warmer." "Grandma's illness is good."

(3) Teacher: (Evaluation) Crows never drink water to drink water. That's a good idea! Where are the good things?

Teacher: Why do crows put stones into the water instead of small pieces of wood? Wood floats on the water and won't sink. )

Teacher: Why don't crows pick the big ones instead of the small ones?

Health: The stone is too big to fit into the bottle mouth.

Teacher: Why do crows put pebbles into the water instead of sand?

Health: The sand is too small for water to rise. Too slow.

Teacher: This is just a clever crow.

(4) Summarize the full text.

1 Teacher: Students, this text is really interesting. Let's review the clever methods of crows and read the text together.

2. The crow couldn't drink water at first, but later he managed to drink water with his own brain. It drank and drank, and its heart was full of joy. Think about what the crow will say at this time.

Health 1: I'm too smart to think of such a good way.

Health 2: This water is really delicious.

Health 3: I feel so comfortable after drinking water.

Teacher: What did you learn after learning this text?

Health 1: Try to overcome difficulties.

Health 2: We should study like clever crows.

Health 3: Don't lose heart when you encounter difficulties. We should calm down and think about what to do, just like the crow in the article.

Teacher: Please applaud Chen Kexin.
