The lesson plan "Sinking and Floating" for the middle class in kindergarten

As a people's teacher who specializes in teaching others and solving doubts, it is often necessary to write lesson plans, which are the link and bridge between teaching materials and outlines and classroom teaching. How to focus on teaching plans? The following is the lesson plan "Sinking and Floating" that I helped you sort out, for reference only, hoping to help you. The lesson plan "Sinking and Floating" for the middle class in kindergarten 1

Activity objectives:

1. Know what is sinking and what is floating when put in water in the exploration activities. And can record the results with ↓, ↑, indicating floating and sinking.

2. On the basis of perceiving the ups and downs of objects in water, try to explore different ways to change the ups and downs of objects. 3. Be able to listen attentively to others and boldly tell your own operation process and results.

Activity preparation:

1. Teaching experiment materials: all kinds of things that can sink and float (toys, small wooden blocks, spoons, etc.), 7 large containers, record sheets, etc.

2. scientific terms and vocabulary: sinking and floating.

Activity process:

1. Guess activity:

1. Teacher: There are many articles in our class today. These articles want to swim in the water. Guess what will happen? (Show the sinking and floating cards) 2. Teacher: You said that some will sink and some will float. I don't know, so let's throw the toys in and have a look.

3, let children boldly guess the ups and downs of other items.

second, children's operational activities: perception of "sinking" and "floating" phenomena.

1. First experiment: Children put things in water to see if the results are consistent with their own guesses. .

2. First recording: recording the results of conjecture and experiment.

3. communication: children exchange the first guess and experimental results with each other to explore whether their guesses and experimental results are consistent.

Third, explore how to float sinking objects with different materials.

1. Baby, some of these things are heavy and some are floating in the water. Now the teacher wants to invite you to play and use your little brains. Is there any way to make the things that were originally submerged float and the floating things sink to the bottom? Tell us your method when you have a good time.

2. Children's operations change the ups and downs of objects and encourage children to try different materials and methods. 3. What methods do you use to make sinking things float? Did it work?

children: the sunken things will sink if you ask the sunken things for help, and will float if you ask the floating things for help. Teacher's summary: the floating things can help the sunken things float; Sinking things can help floating things sink, and it is related to the weight and size of objects. 4. Experience migration Water has many magical powers, but if the water is too big, it will also bring us harm. When there is a flood (picture), everything around us will sink into the water, and so will our people. At this time, what can we do to save ourselves from sinking? (pictures of lifebuoy, footbath, wood, boat, etc.) V. Conclusion.

Scientists are very clever. They used the magical power of water to invent boats and submarines, which can make us walk around in the water. When our children grow up, they can also invent things that sink and float in the water.

design ideas

children will find some strange phenomena in games and daily life: for example, why do boats float on water? Why do some things float on the water and some things sink in the water? And so on, in order to satisfy children's curiosity, explore the science around them, contact the phenomenon of sinking and floating, and make a simple analysis, judgment and reasoning on the phenomenon of sinking and floating, so I designed this scientific activity, aiming to let children explore different methods to change the ups and downs of objects in guessing and discovering.

Activity goal

1. Experience the fun of operation and exploration in the process of exploring the sinking and floating of objects.

2. Perceive the ups and downs of different objects and classify them; Try to explore different methods to change the ups and downs of objects.

3. Try to record guesses and discoveries, and learn scientific methods of prediction and verification.

activity preparation

1. experience preparation: children have accumulated experience about water and initially felt the ups and downs of objects in water.

2. Material preparation: dates, iron clips, plastic bottles, building blocks, stones, foam, sand, recording paper, pens, etc.

activity process

1. observe the phenomenon that leaves and keys are put into the water tank, and simply understand the sinking and floating of objects.

(1) The teacher puts two things into the water tank respectively, and asks the children to observe them.

instruction: what will happen if these two things are put into water?

2. Observe the materials and guess the ups and downs of objects.

(1) Observe the materials one by one.

instruction: what's in your basket?

(2) Play the game "Guess" and record it.

instruction: what will happen if these materials are put in water? Let's count the number of people.

3. Hands-on operation and recording to verify the ups and downs of objects.

(1) Observe the recording paper and discuss the recording method.

(2) freely explore the sinking and floating of objects and record the operation results.

4. communicate the operation results and classify the ups and downs.

(1) Show the recorded results respectively to verify the conjecture.

(2)*** The same summary.

instruction: some of these materials sink and some float in the water. Some things are very big. At first, many people guessed that they would sink, but when they tried, they found that they were not. So you have to try everything to know.

(3) classify according to ups and downs.

Instruction: Now we classify these things. How are you going to divide them?

5. Make a submarine and try to explore different ways to change the ups and downs of objects.

(1) discussion methods.

Instruction: Now the teacher will assign you a task. Please use plastic bottles to make submarines, and use your little brains. Is there any way you can make the original floating plastic bottles sink to the bottom?

(2) Make submarines and try to change the ups and downs of objects with different materials and methods.

(3) Introduce individually and express your own operation results in words.

(4)*** The same summary.

instruction: the bottle is like a submarine, and stones and water are like the ballast of the submarine. When the bottle is full of water, the ballast has enough weight and the submarine dives into the water. If we discharge the water in the submarine out of the cabin, the submarine will float with the decrease of ballast.

6. Play submarine videos to expand your experience.

Instruction: Children are very smart, and scientists are also very smart. They used the magical power of water to invent boats and submarines, which can make us walk around in the water. When we grow up, we children can also invent things that sink and float in the water.

self-reflection:

1. The collocation of the two phrases "float up and sink down" was not clear in advance, so at the end of the experiment, I will hear several children say "float down and sink up", which I didn't consider beforehand.

2. When some groups of children are doing experiments, they scramble for experimental supplies, play with cups, and finally turn paper boats into pulp. This is caused by the fact that I didn't make clear the precautions in the experiment in advance, and the children's standard questions should be taken into account in every activity.

Activity objectives

1. Guide children to observe and compare the ups and downs of objects in the water.

2. Guide children to think positively and boldly express their meaning in their own language.

3. Guide children to try to record the results of observation and exploration with simple pictures.

4. Develop children's observation and imagination.

5. Be able to actively communicate your findings with your peers and stimulate the desire to further explore the ups and downs.

teaching emphasis and difficulty

1. teaching emphasis: guide children to observe the phenomenon of sinking and floating, and be able to describe it in words.

2. Children learn to operate and record with different symbols.

Activity preparation

1. Various vegetables: eggplant, potatoes, spinach (small vegetables), mushrooms, carrots and green peppers

2. Two large basins, one for each person.

3. Box, towel

Activity process

1. Stimulate children's interest in inquiry,

1. Ask questions

Teacher: Baby vegetables are going to explore and meet a big river. Can these baby vegetables cross the river safely?

whoever floats on the water can cross the river safely.

2. Introduce vegetables

The teacher brought many baby vegetables today. Guess who it is?

3. What will happen if you put them in water? Guess what? Which of these vegetables can float on the water? Which ones can sink in the water?

2. Understanding "sinking" and "floating" learning is used to express the phenomenon of ups and downs.

1. children, if vegetables float on the water, we use ↑, and if vegetables sink in the water, we use ↓.

2. Exchange guesses

3. Teacher: How to prove whose guess is right?

3. Keep a record of children's operation activities and perception of sinking and floating.

1. Teacher: Look at the teacher and put a spinach in the basin first. Guess what will happen? What symbol will you use for recording? (Students take notes while observing while thinking)

2. Put a vegetable in the water, see what the result will be, and communicate with the children.

3. Explain the operation requirements: Step 1, which vegetable is put in the water, and observe whether it sinks or floats;

Step 2, take the vegetable out of the water, put it in a box, and dry your hands; Step 3, record the observation results.

3. Children's experiments, teachers observe the children's hands-on operation.

4. Children explain the operation results.

iv. expand and extend, and the activity is over.

Water is really amazing. People have done many things by using its magical power (buoyancy). Do you know what they are? It is this magical power that ships can walk on the sea. We will explore the mystery of water in the future.

reflection on teaching

1. Make bold attempts to observe the ups and downs of objects through children's hands-on operation.

2. In the activity, suitable materials were provided for children to start work, which satisfied the curiosity and desire of middle school children.

3. Use guessing to stimulate children's thirst for knowledge before starting the operation, thus enhancing the purpose of the activity.

4. I fully affirmed the children in the evaluation of the experimental results.

5. The disadvantage of this lesson is that children can't answer what people have done by using the magical power of water because of insufficient preparation.

6. Explore more in the future and guide children to lay the foundation for future teaching work in time. The lesson plan "Sinking and Floating" for the middle class in kindergarten 3

Design intention

Children will find some strange phenomena in games and daily life, such as why the boat floats on the water? Why do some things float on the water and some things sink in the water? And so on, in order to make children satisfy their curiosity, explore the science around them, contact the phenomenon of sinking and floating, and make a simple analysis, judgment and reasoning on the phenomenon of sinking and floating, so this science learning activity is designed.

activity process

1. Introduction of teaching activities

After children enter the classroom, they sit in their seats.

teacher: children, let's see what's on the tray.

2. Guess and record the ups and downs of objects

Teacher: Please guess, children, what will sink to the bottom and what will float on the water after these things are put into the water?

teacher: please write your guess on the record sheet. The record sheet has drawn the materials in the tray, which means sinking and floating. Please tick the corresponding position, and we'll compare it later. Is your guess the same as the operation result?

3. actually operate the object and record the ups and downs. The teacher gave guidance.

teacher: the children have just recorded their guesses on the record. Is the child's guess right? Please put the materials into the water one by one according to the record, and record whether the material sinks or floats in the corresponding position on the record table.

4. Children summarize their own experiments and share their own experimental process and results with children. The teacher gave encouragement.
