Activity intention:
Colorful bottles and disinfectants, various flavors of detergents and cosmetics are very attractive to young children. They may open them, smell them, taste them and even drink them as drinks. If these bottles containing "water" at home are not properly managed, there will be potential safety hazards. Through observation and discussion, this activity learns to distinguish all kinds of "water" in the bottle, satisfies children's desire to explore and understands the dangers hidden in the bottle.
Activity objectives:
1, know several bottled "water" such as detergent, disinfectant and insect repellent, and know that these "water" have different functions.
2. Understand the hidden dangers of bottled "water" with different functions, and know that the "water" in the bottle can't be drunk casually.
3, preliminary understanding of disease prevention methods.
4. Guide children to be willing to receive treatment. Encourage and cultivate children's brave spirit of not being afraid of injections.
Activity preparation:
1, please bring your favorite bottled drinks.
2. One bottle of shampoo, disinfectant, detergent, anti-mosquito water and unmarked water, and one baby pen and paper.
3. Children's learning resources page 12- 15.
Activity flow:
1, know the "water" you can drink.
Let the children show their own drinks and say what they are.
2. Understand the "water" that you can't drink.
The teacher showed the bottles containing shampoo, disinfectant, detergent and mosquito repellent one by one. Look at the color of the water and smell it. Tell me what "water" is, what's the use, and whether you can drink it.
Summary: drinks can be drunk, but "water" such as detergents and disinfectants must not be drunk.
3. Distinguish between drinkable water and undrinkable water.
(1) The teacher mixed all kinds of bottles containing "water" and asked the children to observe and talk about the similarities and differences between these bottles containing "water".
(2) Let children try to put the drinkable water and the undrinkable water together.
4. Show a bottle of unlabeled "water" to guide children to discuss further.
This bottle of water has no label. We don't even know what it is. Kind of like coke. Can we have some to taste?
Summary: Do not drink "water" from unlabeled bottles. These special "waters" can hurt people, and some "poisonous waters" are very powerful. If you accidentally drink it wrong, you should tell an adult immediately and go to the hospital immediately.
5. Guide children to read "Can you tell the difference" and "Help mom and dad find the wrong one" in children's learning resources, and ask children to observe: Where are the drinks at home? Where are the other bottles?
Summary: some detergent and disinfectant are put in the cupboard, some detergent is put next to the washbasin, and detergent is put next to the pool; Bath liquid is placed in the bathroom, perfume and skin care liquid are placed on mom's dresser; Drinks are usually placed in the refrigerator and on the dining table. When children want to drink, they should ask the adults at home to determine whether they can drink.
Activity expansion:
Children design and make danger warning signs in their own way, and mark them with special "water" bottles when they go home.
Activity reflection:
As the scientific enlightenment education for children, the purpose of children's science education is not to pursue the quantity of scientific knowledge, but to stimulate children's interest in understanding natural phenomena and their desire to explore scientific truth, encourage children to actively seek knowledge and cultivate their scientific attitude of seeking truth from facts.
1, in terms of material selection, I chose the content suitable for the age characteristics of children in large classes.
Water is common to children, and children like to play with it. Every time they wash their hands and take a bath, they should play well, such as spraying water with their hands on the faucet or letting the water run down their arms. How to make children have a strong interest in life science while playing, actively explore and think, and accumulate daily life experience, so I designed this scientific activity.
2. Provide enough operating materials of different levels.
These large and small bottles and different caps are familiar to children in their daily lives. Different levels of materials bring different experiences to children, so children are very natural and interested in playing, which greatly satisfies their curiosity.
It provides a relaxed and natural platform for exploration and communication. In this scientific activity, children's interest is stimulated, and independent exploration is the essence of this activity. Play with a bottle with a hole in its body, explore and find out what will happen when the bottle is filled with water, and get the relationship between water pressure and water flow speed through calculation. Then there is a water spray competition game, so that children can feel the relationship between water pressure and water flow speed again and actively try to make the water in their bottles spray far away. Then, on the basis of the existing water spraying experience, let the children play with a bottle with two holes. And around the question of which hole the water is sprayed to, let the children guess-operate-verify, verify whether their guess is correct through specific experiments, and finally draw the correct conclusion.
4. Effective interaction between teachers and children.
In the activity, the teacher's questions play an important role in guiding and supporting children's activities, which can help children think and operate in the problem, so that their hands and brains can actively interact with the teacher to achieve the best results.
In the process of exploration, the teacher is always an active and effective participant, exploring, discovering and excited with the children. At the same time, teachers are also creators of good teacher-student interaction, and supporters, helpers, guides and promoters of children's development. At the end of the activity, the teacher threw a question, and the children played the game again with the question, which made an effective publicity for the activity. The whole activity is to let the children play and learn by themselves.
