Teaching plan of scientific activities in kindergarten middle class "Tadpole becomes frog" 1 Activity name: Tadpole becomes frog.
Activity objectives:
1. Observe the growth process of tadpoles into frogs and understand the living habits of amphibians.
2. Knowing that frogs are good friends of human beings can inspire children to protect frogs.
Activity preparation: picture recording courseware
Activity flow: First, introduce activities to stimulate children's interest.
1, Teacher: What do you hear?
2. Imitate the frog's voice.
3. Teacher: Have you ever seen a frog? Who knows what a frog looks like?
Show pictures of frogs and tadpoles. The teacher guided the children to observe and say the main features.
1, show pictures of frogs, and the teacher guides the children to observe and tell the characteristics of frogs. There are two big eyes on the head, wearing green clothes, a white belly and four legs. )
2. Teacher: Do you know what frogs looked like when they were young?
3. Show the pictures of tadpoles, and the teacher will guide the children to observe and tell the characteristics of tadpoles. Black body, big head and slender tail. )
Third, understand the growth process of tadpoles becoming frogs.
1, Teacher: It's strange that tadpoles and frogs look nothing alike. How did tadpoles become frogs?
2. Teacher: What's the matter? Let's hear a story. The name of the story is "Little tadpoles become frogs".
Warm spring came, the ice in the pond melted, and mother frog slept in the mud pit for a winter and woke up. It slowly climbed out of the mud pit, spread its legs, plopped into the pond and laid many black and round eggs on the green grass.
The spring breeze is blowing gently, the sun is shining, and the water in the pond is getting warmer and warmer. The eggs laid by mother frog move slowly and become a group of tadpoles with big heads and long tails.
They swam around in the water, very happy. A few days later, the tadpole first grows two hind legs, and a few days later, the tadpole grows two front legs. The tail gradually became shorter and disappeared, and the tadpole became a very cute little frog.
3. The teacher plays the courseware while telling the story.
4. Question: What did mother frog give birth to in the water?
What did the egg slowly become?
What did the tadpole grow first, what did it grow, what did it disappear, and what did it finally become?
5. Show pictures to guide children to observe the growth process of tadpoles becoming frogs.
6. Children line up to get tadpole growth cards, and teachers tour to guide them.
7. Teachers and children make tadpole growth cards together to consolidate the growth and change process of tadpoles.
8. Game: Tadpoles become frogs.
Fourth, understand the life habits of frogs.
Where does the frog live? It can live in water as well as on land. It is an amphibian. )
2. What do frogs eat? Mosquitoes, flies and many pests in the field
Fifth, educate children to love frogs.
1, Teacher: What skills does a frog have?
Frogs' greatest skill is to catch pests. )
2. Teacher: How do frogs catch pests?
Frogs secrete mucus in their mouths. When it sees a pest, it will stick out its tongue to eat it. If it is far away from it, it will jump gently and stick out its tongue to eat it. )
3. Teacher: Do you know how many pests a frog can catch a year?
Frogs are experts in catching insects. A frog can kill 10,000 pests a year and protect crops. )
4. Teacher: Frogs have such great skills. How should we protect them?
Conclusion: Don't catch frogs and eat them, and don't do anything that hurts them. I saw someone catching frog tadpoles to stop them. Frog is our good friend, and we should all protect it.
The teaching plan of scientific activities in kindergarten "Tadpoles become frogs";
1. Children learn about the growth process of frogs through activities.
2. Knowing that frogs are good friends of human beings can inspire children to protect frogs.
3. Stimulate children to explore the fun of scientific experiments.
4. Develop children's observation and imagination.
Teaching emphases and difficulties:
The process of tadpoles becoming frogs
Steps of Changing Tadpole into Frog
Activity preparation:
1. Operation card for tadpole growth (one for each person) and several glue sticks.
2.PPT courseware
Activity flow:
1. Introduce activities to stimulate children's interest.
(1) Teacher: What do you hear?
(2) Imitate the frog's cry.
(3) Teacher: Have you ever seen a frog? Who knows what a frog looks like?
2. Show the ppt of frogs and tadpoles. The teacher guides the children to observe and tell the main features.
(1) Show the frog ppt, and the teacher will guide the children to observe and tell the characteristics of the frog. There are two big eyes on the head, wearing green clothes, a white belly and four legs. )
(2) Teacher: Do you know what frogs looked like when they were young?
Show the ppt of tadpoles. The teacher guides the children to observe and say the characteristics of tadpoles. Black body, big head, slender tail. )
3. Watch PPT courseware, the teacher guides the children to understand the process of tadpoles changing into frogs, and distribute the step cards of tadpoles changing into frogs to operate.
(1) Guide the children to discuss how tadpoles become frogs. After learning about the process of tadpoles changing into frogs, the teacher gave each child an operation card.
(2) Children paste tadpoles into frogs step by step, and teachers tour to guide them.
(3) Show children's works.
4. Watch the video "Frog's Life" with children to deepen their understanding of the growth process of tadpoles becoming frogs.
5. Educate children to care for frogs (PPT).
(1) Teacher: What skills do frogs have? Frogs' greatest skill is to catch pests. )
(2) Teacher: Do you know how many pests a frog can catch a year?
Frogs are experts in catching insects. A frog can kill 10,000 pests a year and protect crops. )
6. Teacher: Frogs are so capable, how can they be protected? (PPT)
Summary: children, frogs are our good friends and help us protect crops, so we should protect frogs, don't hurt little frogs, don't catch frogs to eat frogs, and stop whoever catches frog tadpoles, okay?
Design intent:
Warm spring came, the ice in the pond melted, and mother frog slept in the mud pit for a winter and woke up. In this warm season, mother frog enters the water and begins to breed. A tadpole with a long tail and a black body is a descendant of a frog, but how did the tadpole become a frog? The children were curious, so I designed this activity. Let's take this magical change to explore the mystery of how tadpoles become frogs.
Teaching reflection:
Children are in high spirits and can cooperate with each other under the guidance of the teacher to complete the learning task together. A series of activities were used in the short activities, so that children had no time to be distracted and enjoyed it. Through multimedia teaching, children not only have an intuitive influence on the process of tadpoles changing into frogs, but also have a subtle grasp of the important and difficult points of teaching in the process of activities and have repeated exercises. Before the event, I was worried that there would be chaos. However, because it is the first time to use multimedia to teach, and I have grasped the age characteristics of children, the children are very active in the whole activity.
Encyclopedia: Tadpoles wrote "Kodou" in ancient times, which is the larva of frogs and toads, also called toad balls. The newly hatched tadpoles are spindle-shaped, with no limbs, mouth and inner gills, long tail, flat side and branched outer gills on both sides of the head, which are adsorbed on aquatic plants and fed by the remaining yolk in the body.
