"Middle class, soy milk, can do" is the main topic of this article. Today, the editor of Fertility Network specially arranged the article "Record of the seminar on the scientific activity" I can make soy milk "in middle class to share the knowledge about" middle class, soy milk, can do ",hoping to help kindergarten teachers and kindergarten directors. Thank you.

Activity goal: Understand the changing process of tools, learn the method of making soybean milk, and experience the happy mood of making.

Activity preparation: soaked soybeans, stone mortar, stone mill, pulverizer, automatic soymilk machine, electric heating pot.

Activity process:

1, with the title "Bear invites children to make soybean milk".

Teacher: A little bear opened a soybean milk shop. Today, the business is too busy. I want to ask children for help. Would you like to?

2. Know the tools for making soybean milk.

(1) introduces the name of the tool.

Teacher: There are several tools for making soybean milk in Bear's house. Let's get to know them first. (stone mortar, stone mill, pulverizer, fully automatic soymilk machine)

The children are very happy and follow the teacher. While introducing the name of the tool, the teacher briefly talked about how to use the tool. When the teacher introduced, some children went to find their favorite tool and used it manually, whispering in twos and threes.

(2) Encourage children to boldly imagine the basic methods of making soybean milk with these tools.

Teacher: All these tools can be used to make soybean milk. Think about what you would do if you chose a stone mortar or a stone mill or a pulverizer to make soybean milk.

Most children choose a stone mill, and they can tell that they should put soybeans in the small holes on the stone mill and add water, and then grind soybean milk. One or two children talked about the use of stone mortar, knowing how to add soybeans and water and use stone mortar. No child introduced the shredder. Half of them are not familiar with the name of the tool.

(3) The teacher demonstrated the method of making soybean milk with stone mortar, stone mill and pulverizer.

During the teacher's demonstration, two children couldn't wait to squeeze into the teacher's face to see what was going on. The other children shouted, "I can't see the teacher."

3. Learn to make soybean milk.

(1) Children try to make soybean milk with stone mortar, stone mill and pulverizer in groups.

Teacher: Children can choose your favorite tools to make soybean milk. There are four people in each group. After choosing the tools, each group will discuss how to make soybean milk. Children can also visit other groups.

Children's goals are clear, and they occupy their favorite tools. Seven or eight children picked the stone mill, but two children clung to it, so some children had to go to other groups. There were four children left in the stone mill group. Two girls agreed to use a stone mill, but two boys argued. One suggested using "hammer, scissors and cloth" to decide, and the other agreed. However, the little boy who lost didn't want to leave, and the winner shouted, "Teacher, he lost, and he still wants to play this game and won't leave." The teacher took the losing boy's hand and said, "I'm willing to bet and lose. If you lose, you have to go to another group." The little boy cried and wouldn't leave. The teacher took him to the shredder in the canteen and ignored him.

The pulverizer in the canteen is large in size, and it will move when operating, and it also needs electricity. The children feel very difficult, so they ask the teacher for help: "Teacher, we can't get it." So the teacher plugged them in and stepped on the lower end of the pulverizer. The pulverizer was powered on and boomed to work. The crying boy was attracted, and three more children came. They were so happy that some of them added soybeans and some water to the machine. The scene was tense and fun, and a child screamed. All of a sudden, a big washbasin was filled with soybean milk. The beans in this group were also used up quickly, so the children borrowed them from other groups. "Give me some beans." "I have few beans, so don't take them." However, the children of the crushing unit in the canteen still grabbed a handful and left. The children who didn't get the beans kept adding water to the machine. "In this way, the soybean milk will be very thin and you can't add water." The teacher reminded me, so the children who added water stopped. But the kid who borrowed soybeans came back, and he added more water.

The children next to the family crushing unit can't open the lid of the crusher. They are very anxious: "Teacher, this lid can't be opened. Please help us." The teacher used to help them open the lid and pour the soybean milk they had made into a small bowl next to them. The teacher demonstrated opening the lid, but the children in this group still asked the teacher to open the lid three times.

The children in the stone mill group had a good time, only to see that there were many bean dregs on their stone mill, and the soybean milk in the bowl was a little thin, and there was a little bean dregs.

The children in the stone mortar group are vigorously frying soybeans, but there are still some water and semi-broken soybeans in the stone mortar. A little girl in this group said, "We can't get the teacher." "Use a stone stick to pound hard." The teacher finished and demonstrated, but didn't see soybean stains. "Otherwise, take it to other groups for processing?" The teacher suggested.

It's time to stop work. The teacher asked the children to sit down. There are still three or four children around the stone mill.

(2) Children watch the teacher make soybean milk with automatic soybean milk machine, and at the same time cook the soybean milk made by children with electric heating pot.

When the teacher showed the automatic soybean milk, the child shouted, "Teacher, please show us.
