Winter lesson plan for middle class: There are many interesting things in winter.
Teaching preface:
Autumn has passed, and winter has followed. Many children say that they like winter, perhaps because they like its tranquility and meaning.
Teaching objectives:
1 Observe the rubbing phenomenon of sweaters.
2 to stimulate children's interest in doing small experiments
Try to take notes.
Teaching preparation:
Paper, recording paper, old sweater, plastic ruler, plastic stick, pencil, wooden chopsticks, recording paper, wooden comb, plastic comb, wooden stick, etc.
Teaching process:
Warm-up activities: quiet game "birds and birds"
1 Create situations to attract children's attention and arouse their thinking.
Teacher: The sky is in the teacher's hand, and the small table is the earth. Winter is coming, and beautiful snowflakes are falling in the sky! Children, do you want to pick up the little snowflake and play?
Yang: Yes.
Teacher: But as soon as the little snowflake touches our hands, it turns into water. Children, think about what we can do. We can pick up these snowflakes without hands.
Children put forward various methods, one by one, to see if they can succeed.
3. The phenomenon that sweaters rub against various items.
Teacher: Look here, look here, look here. The teacher has a ruler in his hand (draw a table on the blackboard and there is a ruler in the table). Why don't you move? Can the teacher pick up the snowflake with a ruler?
Yang: No.
Teacher: Really? Look at the teacher's magic: a touch of magic makes sesame blossom. (Wipe on the sweater) Then use a ruler to absorb small pieces of paper. Look, what has changed?
Yang: Ah ~ ~
Teacher: Small pieces of paper are attracted. Wipe it gently, little friend. Is it amazing? Take notes on the blackboard and demonstrate the representation of lines.
Teenager: magic.
Teacher: Well, here is a pencil. Let me try it and see if it has magic. Does "magic brush, sesame blossom" (drawing a pencil in the table on the blackboard) attract you?
Yang: No.
(The teacher takes notes on the blackboard to demonstrate the expression of no)
Teacher: Why is there a comb here? Hey, I'll see if I can produce magic (pay attention to creating a situation where I want to try everything when I see it). )。 Ruyi
Teacher, there are wooden chopsticks and sticks (painted on the blackboard). Can these things work magic when they are erased? I want to invite some children to do this experiment.
Teacher: Good. However, Mr. Jiang has a request that what can produce magic and what can't produce magic should be recorded on paper. When children do experiments in groups, they must do it alone, and other children should observe carefully.
Tour guide. Teach children how to take notes when counting.
4 abstract
Teacher: It turns out that plastic rulers, plastic sticks and plastic combs can attract small pieces of paper after wiping sweaters. In fact, many things attract each other because of friction in winter. When we comb our hair, the comb and hair will attract each other. Son, if you find that more things can attract each other after friction, just tell Mr. Jiang, okay? I'll see who has a pair of eyes that are best at discovering mysteries.
