I chose a scientific activity "Frog", and it's spring. Combined with the characteristics of spring, we carried out spring theme education. Because frog is an animal that breeds in spring, mother frog gives birth to many babies-tadpoles. Therefore, children will often go to the natural corner to observe tadpoles and have a strong interest in tadpoles. Once, I asked my children, "Who is the mother of tadpoles?" The child said, "Little Frog". I said, "Why do tadpoles look different from frogs?" Look at me, baby. I look at you. You look confused. Therefore, according to the new Outline, I pointed out that science education should be closely linked with children's real life and make use of things and phenomena around us as the objects of scientific inquiry. Professor Liu Zhanlan of the Central Institute of Education also pointed out that children's scientific inquiry should start with the things around them, guide children to pay attention to the common things in the surrounding living environment, and discover the mysteries, which is conducive to protecting children's curiosity, stimulating their enthusiasm for inquiry, and making them good at observation and discovery from an early age. To this end, I designed this science education activity in combination with the spirit of the new "Outline" and the actual situation of the children in this class.

Second, the main teaching description:

Teaching objective: 1. Guide children to observe frogs and get a preliminary understanding of their appearance characteristics and growth process.

2. Let children know the relationship between frogs and humans.

Teaching preparation: hardware: frog toys or pictures, frog growth process, tadpoles.

Software: Raise tadpoles in advance.

Teaching process: 1. Show tadpoles to lead the topic and stimulate children's interest in observing frogs.

Children, the teacher brought a friend today. Please look who it is. (Tadpole) Do you know who Tadpole's mother is? (frog)

Second, show frog toys or pictures so that children can observe the appearance characteristics of frogs.

"Quack, quack, quack" Hello, children! I am a frog toy made by my uncle in the toy factory according to the appearance of a frog.

4. How many legs does a frog have?

5. Does the frog have a neck? Can you turn your head?

6. Where does the frog live?

Third, initially guide children to understand the growth process of frogs.

Now, all the children know me, but do you know how I became a frog?

1, children first tell the growth process of frogs with the help of existing experience.

2. The teacher shows the frog's growth process diagram and guides the children to observe.

Question: How did tadpoles become frogs? How do frog parents feel under the baby? What did you become when you grew up? What happened in the end?

3. The game of "Little Tadpole Changing into Frog" guides children to show the frog's growth process with body movements.

If you are a baby tadpole, round, what do you do with your body movements? ② What should I do if I become a tadpole? 3 what should I do if I grow back? What should I do if I grow back?

⑤ How to take off your tail?

Finally, the teacher is the mother frog, and the children play with the baby to show the frog's growth process with their body movements.

Fourth, know the relationship between frogs and humans.

1. What does a frog have?

Frogs are very useful to us human beings. How should we protect frogs?
