As a people’s teacher, it is very necessary to carefully design a lesson plan. The lesson plan is the key point in the transformation from lesson preparation to classroom teaching. So what issues should we pay attention to when writing lesson plans? Below are the science activity lesson plans for large classes of "Wonderful Water" that I have collected for you. Welcome to read and collect them. "Wonderful Water" science activity lesson plan for large classes 1
Activity goals:
1. Through experiments, understand the relationship between concentration and water, and become interested in scientific phenomena.
2. Be able to describe the phenomena you see in your own language and be willing to communicate with your peers.
3. Cultivate children’s curiosity about things and be willing to boldly explore and experiment.
4. Be willing to try boldly and share your experiences with your peers.
5. Learn to record your findings in various forms such as language and symbols.
Activity preparation:
Teacher: red saturated sugar water, transparent water.
Children: One piece of rag
First operation: ordinary red water, transparent water (one portion per person)
Second operation: ordinary red water Water, clear water (one portion per person),
Sugar (one portion per group) spoon (one per person)
Third operation: @Red saturated sugar water (per person) Group one portion)
@Sugar (one portion per group) Spoon (one per person) Ordinary red water, transparent water (one portion per person)
Activity process: < /p>
1. Teachers perform magic tricks to arouse children’s interest in activities.
1. Introduction, children guess.
Teacher: Teacher Xie is going to perform a magic trick for the children today. Please take a look. What does the teacher have in his hand? Ask the children to observe carefully. What will it look like when the teacher pours the red water in his hand into the transparent water?
2. Teacher experiment.
Teacher: Please observe carefully, children. The teacher slowly pours red water into transparent water. Can it become two layers?
2. Children try exploratory experiments.
1. Give it a try.
Teacher: Children, do you want to make such magical water? Now please try it with the water on the table and see if you can make such wonderful water.
2. Discussion:
Teacher: Children, have you succeeded?
Teacher: Why didn’t you succeed? (Think about it and talk to the child next to you.)
3. Show the mysterious additive "sugar" and let the children explore again.
1. Show the candy.
Teacher: Because there is something added to the teacher’s water that is not in your water. What is it? (Sugar)
Teacher: There is sugar in the teacher’s water, but do you see the sugar? Where did the sugar go?
Summary: The sugar is dissolved in the water, so we can’t see it.
2. Children conduct exploratory experiments.
Teacher: This time, ask the children to try it again using the materials on the table!
3. Discussion.
Teacher: Children, did you succeed this time?
@Successful. How do you do it? (Share the method of success with everyone)
@No success. Why did adding sugar still fail? (Children’s discussion)
Summary: Put a lot of sugar.
4. Present red saturated sugar water. Toddlers explore.
1. Show saturated red water and let the children observe and discuss.
Teacher: Please take a look at the teacher’s red water with a lot of sugar in it. What does it look like? (Children’s observation and discussion)
Summary: The teacher’s water is very sticky.
2. Children’s experiment.
Teacher: Let’s ask the children to use the things on their desks, put a lot of sugar, and try it again when the water becomes thicker!
3. Discussion.
(1) Teacher: Was it successful this time?
(2) Teacher: Why does red water with added sugar sink? (Children’s discussion)
Summary: A lot of sugar is added to the water. When so much sugar dissolves in the water, the water becomes heavier. And heavy things will sink to the bottom.
5. Extension activities
Children can turn red water into two layers by putting sugar in it. What will happen if you add salt
? What would happen if you put sugar in clear water? Go home and give it a try with your parents! Finally, clear the table yourself.
Activity reflection:
The new "Outline" points out: Early childhood science education is scientific enlightenment education, focusing on stimulating children's interest in knowledge and desire to explore and creating conditions for children as much as possible, using Use various senses, use your hands and brain, explore and solve problems to experience the fun of discovery.
"Wonderful Water" Science Activity Lesson Plan 2 for Large Classes
Materials and Environment Creation
Materials: various sinking and floating toys, cups, bottles, spoons, forks, various colored paints and other items.
Environmental creation: Parents and children are invited to discuss the topic of "water" together to enrich their understanding of water.
Activity process
Conversation - operational perception - narrative discussion
Activity process
The first link: Talk "Water is really useful" ".
Teachers discuss with children the uses of water and how to save water, letting children know: water is really useful. Without water, we humans, animals, and plants cannot survive, so we must save water.
Second link: Operational perception "Water is so fun".
Provide children with operating materials and allow them to carry out scattered and free operating activities. In this link, I let the children operate freely for two purposes: one is to let the children initially perceive the flowing characteristics of water, the other is to let the children observe the color changes of the water, and the third is to let the children perceive the floating and sinking. Therefore, in activities of free operation and free exploration, children can reduce their intuitive mobility and enhance their predictability, which will help children gradually transition from intuitive action thinking to concrete image thinking.
The third link: Narration and discussion (7 minutes)
This link is to organize children to carry out orderly group activities. It is based on the free play in the water in the first link, allowing children to Children, tell me what you used when playing with water, how you played, and what did you discover?
After the children tell the story, the teacher makes a brief summary.
The fourth link: Game: "Blowing Bubbles".
This link is an extension activity. The teacher adds detergent and soap powder to the water and leads the children to blow bubbles together.
Design ideas
Children’s love for water seems to be a natural instinct. As long as they have time and opportunity, they always love to play and have fun in the water, but they are often criticized by adults. Restrictions prevent me from playing in the water as much as I can. Therefore, we often find that young children often get their sleeves wet when washing their hands, or it takes a long time to wash their hands. In order to completely satisfy the children's curiosity, respect their interest in water, and enable them to know more about water, the activity "Let's play with water together" was designed.
The thinking of small class children is still in the stage of transition from intuitive action to concrete images. Their understanding of things is often realized through their own personal activities. Therefore, the entire activity is mainly based on children's manipulation. At the same time, due to the The cognitive ability of children in small classes is still relatively weak, and it is difficult for them to consciously discover some basic characteristics of water. Therefore, some materials should be used to reveal these characteristics of water during the activity, so that children can witness this phenomenon with their own eyes, so that children can easily understand it.
1. Perceive the main characteristics and uses of water in the game, know how to save water, and experience the joy of playing with water.
2. Cultivate children’s interest in scientific exploration activities and their rich imagination and creativity.
The focus of this activity is to allow children to fully experience some basic characteristics of water during water play activities. This aspect focuses on children building knowledge through their own practical activities; the difficulty is to use language to express what they see. This aspect focuses on the cultivation of children's language expression. "Wonderful Water" Science Activity Lesson Plan 3 for Large Classes
Knowledge Background
The knowledge used in this activity is related to saturated solutions and changing the density of liquids. Saturated solution: A solution in which solute can no longer be dissolved in a certain solvent at a certain temperature. Ways to increase solvent density: add solute. The scientific principle of this activity is to dissolve sugar in water to make a saturated solution, so that the density of the solution increases and it sinks to the bottom of the water.
Method Background This activity adopted observation, experiment, inquiry and other methods.
Give it a try:
This is the beginning of the activity. In order to make the children have a strong interest in the activities, the teacher adopted the observation-first method. Ask the children to observe the two liquids in the teacher's hands - a cup of ordinary water and a cup of red water. Ask the children to think: "What will happen if you pour red water into transparent water?" When the teacher sees the red water, A piece of white paper should be placed behind the cup for children to observe. After the children see the water separated into two layers, ask the children to try the two types of water in front of them to see if they can separate into two layers. Let children experiment with their own hands with strong interest, stimulating their desire to experiment and explore.
Let’s talk about it:
This link greatly stimulates children’s desire for language expression. Children can compare their own experiments with the water poured by the teacher. Teachers should try their best to let children say what they want to say, and ask some questions that children are interested in and can answer to strengthen their self-confidence. Heart.
"Is the water the children poured the same as the water the teacher received? Then do you know why?" The teacher can say the answer under the eager anticipation of the children, "Put a lot of white sugar into the red water, stir it vigorously, until "Until it melts." Let the children understand that red water can sink to the bottom because there is a lot of sugar in it, and the water becomes heavier, and heavy things will naturally sink to the bottom.
Do it:
This link adopts the method of children’s own hands-on experiments. During experiments with young children, they know what kind of liquid can sink to the bottom of the water and what methods are used to make such liquids. Let the children compare with the first glass of water to know the difference between the two glasses of water.
1. The goals of the "Outline" and the national "Science" curriculum completed in this activity are:
1. Cultivate children's hands-on operations through children's observation and experiments. Ability and ability to explore things. Stimulate children's curiosity and desire for knowledge.
2. Encourage children to use appropriate methods to express and communicate the process and results of exploration.
2. Demonstration plan
(1) Activity goals: 1. Through different water changes, cultivate children’s interest in scientific phenomena and develop a preliminary desire to explore.
2. Cultivate children’s hands-on ability during their experiments.
3. Be willing to express the phenomena you see in your own language and be willing to communicate with your peers.
(2) Activity preparation: two cups of red water, one cup of transparent water, white sugar. Small spoon (each child has one copy of this material)
(3) Activity process:
(4) Activity process: 1. Take a look and think about the conversation topic: " Children, look, what does the teacher have in his hand? Ask the children to think about what will happen if the teacher pours the red water in his hand into the transparent water." (The teacher poured the red saturated sugar water into the water. Pour it into transparent water and ask the children to observe carefully. In order to make it easier for children to observe, put a piece of white paper on the back of the transparent cup. The children can see that the red water sinks to the bottom of the transparent water and forms two layers. Very beautiful. )
2. Give it a try: Introduction: "Children, do you want to make such beautiful water? Now please try it with the water on the table and see if you can. Make such wonderful water.” (The teacher provides the children with a glass of transparent water and a glass of red water, and asks the children to pour it out to see if they can pour out two layers of water.)
3. Let’s talk about it: Introduction: Children, have you made some beautiful water? Is it the same as the water the teacher made? (The teacher asks the children to speak boldly about the methods and results of their experiments) Introduction: "Children, do you know why your water can't be as beautiful as the teacher's? Ask the children to see the difference between the teacher's red water and the children's red water. "Please observe carefully: children's water is very thin. The teacher's water is very thick, like honey, sticky. Tell the children: "Because the teacher added a lot of sugar to the water, so much sugar melted in the water, the water became heavier. And heavy things have to sink to the bottom, so the red water will be underneath, transparent The water becomes two layers. ”
4. Do it: Ask the children to use the things on their table (a cup of red water and white sugar, a cup of transparent water) to make magical water. The teacher instructs the children to put the sugar into a transparent cup with a small spoon, emphasizing that more sugar must be added until the sugar cannot melt in the water. Slowly pour the red water with white sugar into the transparent water. Ask the children to observe carefully. Have you made the wonderful water?
(5) Activity evaluation: The science activity "Wonderful Water" is very suitable for children in the upper class. Children in the upper class are very curious and would like to have the opportunity to make things they like. This activity is not difficult, but the results are easy to see, allowing children to strengthen their self-confidence through successful results. Through this activity, children's observation, comparison and hands-on operation abilities have been developed to a certain extent, and their language expression ability has been greatly improved. "Wonderful Water" science activity lesson plan for large classes 4
1. Activity goals:
1. Be able to become interested in scientific phenomena and develop preliminary interest in exploration.
2. In experiments, it was found that salt dissolved in water will increase the buoyancy of water. The more salt, the greater the buoyancy.
3. Be willing to express the phenomena you see in your own language and be willing to communicate with your peers.
2. Activity preparation:
Cups, grapes, salt, recording paper, video "Dead Sea" related information
3. Activity process:
(1) Stimulate interest and elicit activity content.
1. Conversation introduction.
“Children, do you still remember how to make the eggs float?” (Children recall their experiences)
2. Summary of the teacher’s questions.
Why do eggs float when you add salt to water? It turns out that salt dissolves in water and increases the buoyancy of the water, causing the egg to float. (Children talk one by one: buoyancy)
(2) Children’s operational activities.
Transition: Does adding salt make objects float? (Children’s guess)
1. So what exactly is it? We'll try it ourselves later. The teacher prepared a glass of water for each of you on the table, and asked you to add 1 packet of salt at a time, stir it thoroughly with chopsticks, add grapes, and see what the result is? And write it down on paper. Remember: try once and remember once.
2. Children's operation
3. Communication: I found that the children at table No. 1 moved very quickly. Why don't I ask them to talk about their findings? (Group No. 1: I added 1 or 2 packets of salt, but the grapes did not float. I added 3 packets of salt, but the grapes floated.)
4. Why did I add 1 or 2 packets of salt? The grapes didn't float? Will the grapes float after adding 3 packets? (More salt)
5. Teacher’s summary: Yes, if you drink 1 packet of salt as water, the buoyancy is very small and you have no power to lift the grapes. If you add 2 packets of salt, the buoyancy is still too small. You can only drink it as water. Only when you drink enough salt can you have the strength to hold up the grapes and make them float. It shows that the more salt, the greater the buoyancy.
6. Which other group is willing to introduce your findings? (Group No. 2: I added 1, 2, and 3 packets of salt, but the grapes did not float. I added 4 packets of salt, and the grapes floated.)
7. Teacher questioned: You just introduced you After the discovery, the teacher had a doubt: Why can table No. 1 only need to add 3 packets of salt to make the grapes float, while Table No. 2 needs to add 4 packets of salt and Table No. 3 needs to add 5 packets of salt? (Observe the water in the cups at table 3,) How much water is there
8. You have all discovered that (show the mark) the water in the cup at table 1 is the least, and the cup at table 2 has more water. , Table 3 has the most water in the cup) Oh? Does the amount of water and salt added also matter? What is the relationship? (Children’s discussion)
9. Summary: It turns out that the more water you have, the more salt you need to drink. Only when the water is filled with enough salt can the grapes be lifted up and float.
(3) Watch the video.
1. In addition to eggs and grapes, can our people float? (Children’s guess) Let me tell you, our people can actually float, do you believe it? Let's watch a video together.
2. Children watch the video
3. It’s really magical! Who can tell me: Why can people float? It turns out that this is not an ordinary sea, but the Dead Sea. Its salt content is 6 or 7 times higher than our ordinary sea water, and its buoyancy is very high. No wonder we can lie on it.
(4) Extension activities.
Just now some of our children floated the grapes, can we make them sink again? You can try it yourself. "Wonderful Water" Science Activity Lesson Plan for Large Classes 5
