1.Through interesting operation activities, you can perceive the existence of air and have a preliminary understanding of the characteristics and functions of air.
2.Use hands-on brain ** questions to stimulate children's interest in science activities.
Event preparation
1.(Experience preparation): Before the activity, let the children have a preliminary understanding of the air, and let the children look for the existence of air around them.
2.(Material preparation) a transparent cup with one-third of water per person, a straw, a chalk per person, and a number of plastic bags.
Activity process:
One. Import the activity
1.The teacher shows a balloon that has been blown up, and visually demonstrates the topic, and asks the children to take a look at why the balloon is fat. The teacher concludes that there is air in the balloon that has been blown up.
2.Show the question and the toddler guesses.
Why are balloon dolls flattened? So where did the air baby go? Could the children please come and guess? (Toddlers are free).
3.Teacher's guidance: The children have a lot of ideas, so where did the air baby go? Will it run into our bodies? Let's play a fun game 'Find Air Baby' together.
Two. Experimental manipulation
a) The air in the body.
1.Clarify operational requirements:
1）.First of all, insert the straw into the water, and then blow into it, note that the straw can only be used for blowing, not washing.
2）.When blowing, you have to watch carefully to see what happens?
3) Don't blow too hard and don't spill water.
2.Ask the child to insert the straw into the water cup and blow vigorously to feel the presence of air in the body, and the child will see what he sees'phenomenon to communicate.
3.Teacher's Summary: We have air in our bodies.
b) The air in the chalk.
1.Clarify the operation requirements: slowly put the chalk into the water and carefully observe what is happening?
2.The children slowly put a small amount of chalk into the cup, observe what happens, and communicate what they see.
3.Teacher's summary: There is also air in the chalk.
c) The air around you.
1. Teachers guide and children demonstrate how to catch air.
2 The children take the plastic bag to operate, sense the air around them, and the children narrate.
3 Teacher's summary: There is air all around us.
3. Experience and perceive the role of air.
1 Do children know the role of air? Now please do a little game with the teacher, please close your mouth, cover your mouth with your hands, and cover your nose with your hands, how do you feel? (Breath-holding, uncomfortable).
2 Teacher's summary: In fact, not only we humans need air, but also small animals, flowers and grasses, so do you know what else air can be used for? The teacher shows the ** of flying kites and parachutes.
The Air Baby is so capable that it can do so many things, and children want to be good friends with it.
4. Extension Activities:
The children used plastic bags to grab the air outdoors and felt that the air was everywhere.

It's good to have a lot of help.
I used to take the "metal activity sequence" review of the regional-level open class, more than ** classroom there are nearly 300 teachers listening to the class and 80 students in class, their own courseware, from the introduction of new lessons, the main review points, knowledge network, student experiments, example analysis, classroom exercises and other aspects can be interspersed freely, the classroom form has explanation, animation, **, etc., students like it very much, said that even the teacher who came to listen to the class did not feel that the review was fried rice. Of course, this requires good courseware creation inspiration and multi-processing technology for text, animation, sound, and image. >>>More
