Teaching plan of "How does an object absorb water" for kindergarten teachers' recruitment science class.

In daily life, children are very interested in things around them and often ask "why". Once a child was wiping his hands, and a child asked me, "Teacher, after I washed my face, there was water all over my hands and face. Why did I wipe it with a towel and the water disappeared? " In view of the common phenomenon of water absorption in life, we designed this activity to catch children's interest. The purpose is to stimulate children's interest in exploration through teachers' guidance of children's experimental activities, so that children can feel the ubiquitous water absorption phenomenon around them, thus cultivating children's interest in scientific activities, developing children's observation ability and hands-on operation ability in activities, and initially cultivating children's ability to record experimental operation results with a recording table.

Instructor: Jiang Na

Name of activity: scientific activity "water absorption"

Activity goal: 1. Through experimental operation, we can know which objects can absorb water and compare their water absorption characteristics.

2. Stimulate children's interest in exploration.

Activity preparation: disposable lunch box, water, toilet paper, sponge, cloth, chalk, plastic paper, building blocks, coins and record sheets.

Activity flow: 1. Import (small magic)

Teacher: Good afternoon, children. Welcome to our lab. Before we start the experiment, we always show you a little magic. Let's see, what miracle will happen? Teacher's operation: Fold the white rice paper into a square and immerse the four corners in different colors of water in turn.

Teacher: How did the teacher do it? What did you observe?

Yang: I saw the teacher standing white paper like water of different colors, and then the white paper turned into colored paper.

Teacher: What does this mean?

Teenager: White rice paper can absorb water.

Discussion: What materials can absorb water in life?

Teacher: In the little magic performed by the teacher just now, we found that white rice paper can absorb water. Then the children use their brains to think about what else can absorb water in our life. Children, discuss with the children next to the county seat.

Young 1: toilet paper.

Young man 2: Towels.

Teenager 3: clothes.

Teacher: The children said several things that can be used for swimming. Today, the teacher also prepared some materials for everyone in the laboratory. However, like children, I don't know which of these materials can absorb water and which can't.

3. Experimental operation.

1. Introduce the experimental materials and requirements.

Teacher: Let's have a look, children. What is our experimental material?

Yang: There are toilet paper, sponges, coins, building blocks, plastic paper, chalk and cloth.

Teacher: In our laboratory, there are some small requirements. I believe that every child can abide by them well and do experiments seriously. (1. Take out the record sheet first and put it on your right. 2. Pick up each material, just dip it in the water, and take it out immediately and put it in the homework basket. 3. Keep the desktop clean and tidy. 4. Every time you finish the experiment of a material, you should start recording. Record while doing. )

2. Children's operation.

Please tell each child the result of the experiment.

4. Teacher verification.

1. Teacher's experiment

Teacher: The children's experiment is over. Next, let's check with the teacher to see if your operation result is correct. The teacher operates the experiment, records the results and shares the operation results with the children.

2. Teacher's summary: In the experiment, we found that toilet paper, sponge, cloth and chalk all absorb water, among which toilet paper absorbs water faster, while plastic paper, coins and building blocks do not.

Verb (abbreviation of verb) abstract

Today, the teacher and children did an experiment about water absorption. When we get home, we can do this little experiment with our parents again. Observe their water absorption.
