1. How to write a silkworm record card in primary school?First of all, you must have experience in raising silkworms. If not, you can let your children read some books about the growth process of silkworms. They will have a general understanding and will have content to write about. 2. How to fill in the silkworm growth record sheet?The growth record of silkworms should first record the time, secondly the temperature, and thirdly the length. 3. How should the growth in the silkworm breeding record be filled in?The young silkworms swim slowly in the mulberry leaves, crawl around, grow slowly, then spin silk, shrink themselves in the silk, turn into pupae, then shed their shells, crawl out of the pupae, turn into small insects, and repeat the cycle over and over again? 4. What methods can be used to record silkworm breeding?Silkworm breeding records can be recorded in the form of a diary to record the daily growth and changes of silkworms. Silkworms slowly hatch from small black seeds and grow up little by little. Recording this process can exercise children's observation ability and cultivate children's patience. In the growth of silkworms, children sometimes need to learn some knowledge by looking for information. Parents should support and help their children. 5. How to write reading notes on sericulture?One day, my classmate gave me some little silkworms. They were black, tiny and very cute! As soon as I got home, I took out fresh mulberry leaves for the silkworms to eat. The silkworms nibbled and nibbled for a long time before they nibbled one leaf. I was worried that the silkworms would starve if they continued like this. So I turned on my computer to look up information about raising silkworms. It turned out that the mulberry leaves were too big for the silkworms to eat. So I took out a pair of scissors, cut the mulberry leaves into strips, and then fed them to the silkworms. As time went by, the silkworms, under my careful care, shed their skin four times and became big, white and fat silkworms. One day, I just got home from school, and I dropped my schoolbag to look at my silkworm. Hey! My silkworm has changed. It has become shiny. It is busy in a corner of the paper box. There are a lot of silk in the corner. Oh! My silkworm is about to make a cocoon. The silkworm keeps spinning silk. I found that it has become thinner and smaller. Gradually, it was covered by shiny silk. Two days later, a beautiful oval cocoon appeared in front of my eyes. The silkworms left precious silk to people, but they were about to end their short lives. I also understood the truth that "the silkworms will not stop spinning silk until they die." 6.
