1, perceive the air as colorless and tasteless, invisible and intangible, and know that there is air everywhere around us;

2, can use a variety of senses to learn simple ways to explore the air. Stimulate children's desire to explore and cultivate their interest in scientific experiments.

3. Cultivate children's awareness of caring for and protecting the environment.

Activity flow:

Good morning, children! Today, the teacher is going to do a magic trick. do you want to see it ? (Thinking) Look at that little eye carefully!

What is this (towel)? Is it dry or wet? Come on, children, touch it with your hands. What kind of towel is this? This is a dry towel. What is this? (Cup), the teacher is going to put the towel in the cup now, and then put the cup directly into the water ... Can you guess if the towel will get wet? (Please say ...), then let's take it out and have a look. Is it wet? Children, touch it with your hands. Are you wet? Gee, it's strange that the towel was put in the water, but it wasn't wet. Isn't it amazing? Now, the teacher will perform another magic trick. This is (towel) and this is (cup). We will also put towels in cups. This time, the teacher will put it into the water sideways, so the children will watch carefully. See what happens (bubble formation). Children, guess whether the towel is wet (tell me ...) Is the towel wet after all? Let's take a look. I twisted it with my hand. Is it wet? Why is the towel wet? This time the teacher's cup was put in obliquely. There is air in the cup obliquely, and the air comes out. Tell me, children, what has come in? Yes, the air came out and the water went in, so our towel was wet, but it was not wet for the first time, because the air came out, so the towel was dry. Just now the teacher gave you two tricks about air. Does it look nice? (nice)

So where is the air? What kind of thing is it? Let's do an experiment next. Look, children, what is this (bag)? I'm going to catch the air with a bag and see where the teacher catches the air (I grabbed a bag from under the table with a red bag). Hey, I caught a bag of air. Tell me where I caught it. (catch it from around with a bigger white bag, and then catch it from the corner with the biggest blue bag) ... and catch a big bag of air next to it. Do you want to get some air, too? Let the children take a bag from the teacher. Do you all have them? Now, let's open the bag to take a breath. After we catch it, we should hold the bag tightly and lift it up. Let me see. Who can catch more air quickly? You are really capable! Now, let's slowly open the bag and look at the air with our eyes. Can you see the air in the bag? (Invisible) Yes, air is invisible; Is the air in the bag colored? Air is colorless. (Grab it again in the same way) Open the mouth of the bag and smell it with your small nose. Does the air in the bag smell? Yes, the air is tasteless; Touch the bag with your little hand. Can your little hand touch the air in the bag? Air is untouchable. Let's get some air somewhere else, shall we? See if you can breathe air. Play background music and take the children everywhere to get some air. Ok, please put the bag back. I let the children talk to each other. Where did you catch air? Tell the children next to you where you caught the air and speak freely. Okay, are you full of air? Do you think air can be seen? Do you have any colors? How does it taste? Can you touch it? It turns out that we have air everywhere. Air has no color, no taste, and can't be seen or touched. Therefore, children usually think that there is nothing around us. In fact, air does exist. How do we feel when we use a small fan? What's it like to blow through your mouth again? This shows that air exists and flows.

Besides, the air is interesting. Let's play air baby together, shall we? Let's blow the water in the cup with a straw and see what happens. Is there a difference between blowing gently and blowing hard? Come on, start with you, one by one. ..... Well, please come back! Children, have you ever played with balloons? Today, the teacher also invited you to play with balloons. Are you happy? But, first think about it, how to make the balloon inflate? (Blowing into the balloon), how to make the balloon blow bigger? If the balloon is small, does it mean that we blow in more or less air? Let the children take a balloon from the teacher. (Ask some children when playing again) Well, the balloon babies are tired, please take them home. The little basket is its home. Oh, air baby is so fun. I want to play with air baby, too.

Look, children, what is this (candle) and what is this (lighter)? Now I'm going to light it and light the other one. I'm going to put the cup on the candle. The children wondered what would happen to the candle and whether it would go out. (Please tell me ...) Look carefully, little friend. Where are the candles? Would you like to have a try? Please come to the back, and each of us will find a cup. Be careful when you cover it, don't let the candle burn your hand. Ok, please bring the child back! Did you see the candle go out? But the candle covered by the cup went out. Didn't you notice how the candle was put out just now? Is it slow or fast? Then let's take a look again. This time, the small eyes should look carefully. Oh, the candle went out slowly. Why do candles go out when they are covered with cups? (Tell me ...) The teacher told you the real reason: This is because the cup covers the candle and there is air in the cup. The ingredients in the air that can make the candle burn are used up, but when the outside air can't get in, the candle goes out. Tell me, do candles need air when they burn? Do we need air when candles burn? Tell me about it. Let's do a little experiment. Shut your mouth and cover your nose. How would you feel if I asked a child to talk about it? Is it uncomfortable? Why do you feel uncomfortable? Because we close our mouths and cover our noses, air can't enter our mouths and noses, and we can't breathe air, so we will feel breathless and very uncomfortable. Do you think we need air? We humans need air, so do animals. What about flowers and trees? Air is also needed. Where there is life, air is needed. What if there is no air? You can't survive.
