Children recall that silk was spit out by silkworms. (Silkworm cocoon is only the protective body of silkworm chrysalis)
2. Look at the pictures about sericulture.
3. Teacher's summary
Third, silk painting activities.
1, watch the video to get a preliminary understanding of the silk drawing method.
Think about how people spin silk from cocoons.
(Children guess how to spin and practice)
The children talked about many methods of extracting silk from silkworm cocoons. How did cocoon become the silk we need? (Watch the video)
(3) Please tell the children the specific method of extracting silk from cocoon.
Teacher's summary:
A specific method for extracting silk from silkworm cocoons,
Pick the messy silk-making solution-soaking-spinning head-spinning.
We turn cocoons into silk, which is the process of spinning.
2. Guide children to spin silk
Teacher: Today, let's be silk workers together. Let's silk.
Specific methods: while watching the video, learn the specific operation methods of each link.
(1) thread (watch video)
Question: Who will be the little teacher now and tell you how to pick out the messy silk?
(single child operation).
(2) solution preparation: baking soda is soaked in hot water.
This solution is baking soda solution.
The different content of baking soda in this solution and the different temperature of the solution will affect the reeling effect of cocoon.
Because of the high temperature, the teacher poured the hot water. Be sure to pay attention to safety in future operations, and don't burn yourself.

Let the cocoon soak in hot water. In order to fully soak, you can use chopsticks to press the cocoon into the water (pictured) until some fluff appears on the cocoon surface.
The soaking time is about 1 min.
(4) spinning with a spinning head:
Teacher: When we picked silk, we found that many silk sticks to the floor. At this time, it is necessary to sort out the silk script and find the silk head.
(5) Is there any good method?
Children can freely publish the methods of spinning and picking threads, and make records (attached table 1).
Please watch the video of finishing silk.
3. Children demonstrate rotation
Have you learned to find a spinneret to spin silk? Teacher, this is just a soaked cocoon. Who will find a way to find the thread head and let the children do it?
4. Guide winding
When we find the thread end, we will stick the silk thread on the winding tool and start winding.
(The child said that he guessed the winding tool and made a record. Use table 2)
5. Children's group spinning activities
(1) Now let's start spinning together, but the teacher has several requirements:
Compare which group draws well and draws long;
Run quietly, the music rings and the activity stops; And sort out the material in the music.
(2) children's operation, and make records, the teacher to guide the operation method.
Fourthly, exchange the winding tools and winding methods of each group to understand the advantages and disadvantages of several winding tools.
