Activity flow:
First, guess the riddle and lead to the theme of insect activity.
-The teacher read the riddle children's songs of bees and asked: What animal is this?
-The teacher read "The Riddle of Dragonflies" and asked: What animal is this?
-Let children guess riddles and arouse children's attention to insects.
Second, display insects, or enlarge insect specimens with a physical display instrument to perceive the main characteristics of insects and stimulate children's interest.
Teacher: What is this? What's your name?
-Teacher: What kind of person is he? What's that on your head? What's under you? How many pairs of wings and feet are there?
Teacher: Do you know where he lives? Do you want something to eat?
Third, guide children to read "children's books" and inspire them to tell stories according to "animal names-physical characteristics-living habits".
-Children look at the picture independently and inspire them to say: What insects are there in the picture? What do they have?
-Teacher: Where do they live? What to eat? What do they have in common? They have the same name, you know?
-Teacher's summary: These bugs on the screen have the same name as "insects". The body of this insect is divided into three parts: head, chest and abdomen. There are tentacles, mouth and eyes on the head; There are three pairs of feet on the chest and two pairs of wings on the back; The abdomen is segmented with air holes on both sides, which is used for breathing. Some insects, such as ladybugs, have a pair of hard wings, while others have only a pair of wings, such as mosquitoes.

6. Preliminary perception of beneficial insects and pests.
Teacher: In the big family of insects, which are beneficial insects and which are pests for us humans?
Teacher: Do you know whether butterflies are beneficial insects or pests? Why? (Butterfly larvae like to eat tender vegetables, but it has the advantages of spreading pollen and watching after turning into butterflies.
-Lead children to discuss: How should we treat insects?
Let children know that they should pay attention to environmental hygiene, do not dump garbage indiscriminately, do not urinate anywhere, and do not let dirty water gather, so that pests cannot survive. At the same time, we should also protect beneficial insects and don't kill them at will.
Through this activity, children feel the beauty of insects in nature, know common insects, know their skills, know their growing environment and experience the fun of making insect specimens. They have the consciousness of protecting beneficial insects and eliminating pests, not only experiencing the fun of activities, but also increasing their knowledge, and all fields have been developed to varying degrees.
Teaching reflection:
Starting from children's interests, combined with their actual development level, this activity has gradually deepened, which not only meets the needs of children's development, but also improves their enthusiasm and initiative in participating in activities. But there are also some links in the activity, which are difficult for some children to understand because of their strong knowledge. How to gamify the link of children's knowledge and better stimulate children's interest will be the subject to be discussed in the next topic.
