Activity purpose:

1, cultivate children's interest in observing snails and their concern for life.

2. Let children understand the general process of scientific inquiry, gain some personal inquiry experience, and initially cultivate children's ability to ask, analyze and solve problems.

3. Through regional group activities, let children gradually develop the good habit of taking notes while doing experiments, and learn to cooperate with each other and share the fruits of labor.

4, through the understanding of snails, practice the ability to describe in more accurate language.

5, initially cultivate children's scientific attitude to explore problems, know how to learn to read materials to gain more knowledge.

Key points:

Understand the general process of scientific inquiry and guide children to make records while doing experiments.

Activity preparation:

1. Scene layout: Set the scene as a laboratory, put some photos and books about snails, five magnifying glasses, "lovely snail" cards, five desks, tape recorders and tapes.

2. Materials needed for the art area: drawing paper, oil pastels, plasticine, wrinkled paper, wool, glue, scissors, photos and books about snails, and real snails.

3. Materials needed in the tension experiment area: buttons, snowflakes, keys, building blocks, fish plugs, erasers, wooden beads, toy cars, screws, a cigarette, transparent glue, thread, ruler, pen, recording paper, real snails, cabbage leaves and napkins.

4. Materials required for the skill test area: homemade ladders, homemade trekking poles, homemade wire ropes, homemade slopes, cups, keys, toy cars, transparent glue, lines, pens, recording paper, real snails, cabbage leaves and napkins.

5. Materials needed for the "What Snails Eat" experimental area: chopped Chinese cabbage, peppers, radishes, onions, tomatoes, apples, bananas, paper, dried apricots, raisins, sand sugar, salt, mutton, bread crumbs, real snails, napkins, plates, pens and recording paper.

6. Materials needed for the "Happy Home" experimental area: real snails, containers for snails, a bucket of rotten soil, watering flowerpots, some tree forks, rockeries, pavilions, small trees, small ponds, crepe paper and wax paper for children's decorators, word baby "Snail Home", rags and trash cans.

Activity flow: (light music runs through the whole process)

One: arouse children's interest by "playing in the snail world".

1, the teacher talks to lead the children into the snail world.

2. Visit the snail picture exhibition and guide the children to ask: "Where is the real snail?"

The teacher turned out a snail and asked the children if they would like to be friends with this snail.

Give each child a snail, guide the children to observe and discuss, tell the shape characteristics of the snail, and the teacher makes a final summary.

4. Guide children to ask various questions and guess how to solve them.

5. Cultivate children's ability to ask questions, analyze problems and solve problems.

2. Experimental inquiry activities: Teachers introduce the names of experimental areas and guide children to tell the materials and uses of each experimental area. The children choose their favorite areas to start the experiment, and the teachers tour to guide them.

1, art district

Objective: Through the understanding of snails, let children express snails in the form of painting or handwork, and cultivate their feelings of liking snails.

2. Tension experimental area

Objective: To know that snails crawl with their stomachs, which are very capable.

Cultivate children's ability to design their own experiments, guide children to record while doing experiments, and enhance their interest in learning.

3. Ability test area

Objective: To make children understand the general process of scientific inquiry and gain some personal inquiry experience. Through experiments, let children know that snails are timid, but they are very capable. They should learn from the snail's spirit of not flinching when encountering difficulties.

4. What do snails like to eat?

Objective: To let children know more about the feeding habits of snails by feeding them.

5. "Happy Home" construction area

Objective: To understand the living habits of Oncomelania hupensis. Children use their imagination to decorate the snail's home with existing materials, and cultivate their hands-on ability and love for small animals.

Three. Collective education activities

1, let the children send snails from all regions to the snail homes that have been built.

2. Summarize the experiment and encourage the children who do well in the experiment.
