As a people's teacher, it is always necessary to compile teaching plans, which are the basic conditions to ensure the success of teaching and improve the quality of teaching. What formats should I pay attention to when writing lesson plans? The following is the lesson plan of "Interesting Candles" compiled by me for everyone. Welcome to read and collect it. Interesting Candles lesson plan 1
Activity objectives:
1. Learn about all kinds of candles through observation and tell their uses in daily life.
2. Be able to actively participate in self-made activities and experience the happiness of success.
3. Have a preliminary understanding of the relationship between candle burning and air, and have a strong interest in this phenomenon.
Activity preparation:
Some candles, some transparent glass bottles, a glass cup, some candle slides, some homemade candle molds, some wax cores, and music.
Activity process:
First, create a situation, enjoy candlelight and arouse interest.
1. Teachers lead children into the classroom and feel the beautiful and warm candlelight together.
2. Guide children to observe lit candles and talk about interesting phenomena they see, such as: the dripping candle oil is like tears, and it is a little hot; Small flames will dance with the wind. Tell me what a small flame looks like. (Like stars, like stamens, like the sun, like fireflies ... ……)
3. Guide children to show the appearance of candlelight with their own actions.
second, let children know the use of candles in daily life by watching slides and various kinds of physical candles.
1. Please have a look at the slides and enjoy the beautiful candles.
2. Teachers invite children to enjoy all kinds of candles.
3. Guide children to tell the purpose of candles and talk about when they used candles. (When there is power failure, birthdays, lanterns ...)
Third, teachers and children make their own candles.
1. Teacher's introduction materials: melted wax, wax core and mold.
2. The teacher introduces the production process.
(1) Children choose their favorite molds.
(2) Children take a wick and put it into the mold. (Requirements: wax oil should not be higher than wax core)
(3) Spoon the melted wax into the mold and solidify it.
fourth, the game "the candle goes out".
1. Ask children to talk about how to light candles. (matches, lighters ... ……)
2. Guide children to put out candles in different ways. (fan with your hand or blow with your mouth)
3. The teacher put out the candle in another way. First light a candle, fix it, and then cover it with a glass cup. What's the result? (Extinguish)
4. The teacher guides the children to cover the glass on their desktop on the lighted candle, with the bottle mouth close to the coin, to see what are the similarities and differences with what the teacher just did. (Similarities: The candle went out. Difference: there is a rising water column in the bottle)
5. Summary: The candle needs air to burn. When the air in the cup is burned out, the candle will go out. Just like us, we also need air.

5. Summary: The candle needs air to burn. When the air in the cup is burned out, the candle will go out. Just like us, we also need air.
5. Appreciate homemade candles. Interesting Candles Lesson 3
Activity goal:
Explore the relationship between air perception and combustion through operation.
actively participate in experimental exploration.
cultivate mutual courtesy and learn the ability of division of labor and cooperation through experiments.
Important and difficult points in the activity:
Air is needed for burning
The relationship between the burning time of candles and the amount of air
Activity preparation:
Candle lighter cup record
Activity process:
First, setting doubts and arousing exploration interest
(1) The teacher shows a candle to guide children to divergent thinking.
teacher: what can you do to make the candle light up?
(Blow, fan ...)
(2) Guide children to think reversely. Teacher: How can we put it out?
(Blowing, fanning ...)
Second, the first experimental exploration activity, sensing burning needs air division: Now let's do a small experiment, and the teacher lights two candles. Please carefully observe how I put out one of them. How did it go out?
(The teacher lit two candles, one with a cup and one without a cover)
1. What did you observe?
(The cup is out, but the cover is not out)
2. Why is this candle still burning?
(air ... ……)
3. How did this candle go out?
(cup) (slowly goes out bit by bit)
4. Why does the candle go out bit by bit when the cup is covered?
(Air ...)
Summary: Combustion needs air. If there is less and less air in the cup, the candle will go out slowly.
third, operate in groups to further perceive the relationship between air and combustion. Teacher: Let's do another small experiment. Please sit in your corresponding group and see what you can do first.
1. Teacher: Let's see, are the cups used in this experiment the same size? (Not the same) In the next experiment, please carefully observe the difference in the burning time of candles in cups.
2. This experiment needs to be completed by the first group of children, but the division of labor is different. One child will light candles and three children will have cups. Now, we will give you one minute to negotiate. Please sit down above after the discussion.
3. Who will light the candle?
requirements: who will cup the air?
requirements: a cup covers a candle, and it must be covered at the same time. Is there any way to cover it at the same time?
(...) Then we'll use this method.
4. Introduce the record sheet. Please use lines to indicate the burning time of candles.
5, children's operation, teacher tour guidance.
6. Communication results Who will tell you the results of your records?
why is this happening? Is there as much air in the cup?
fourth, activity extension: how to make the candle that is about to go out burn again? Interesting Candles Lesson 4
I. Design Intention
In daily life, I find that children especially like to "play with fire", such as striking matches or playing with lighters, or lighting paper and rags with fire. This is very dangerous and is not allowed by adults. Seeing this phenomenon, on the one hand, I feel that not letting children "play with fire" will stifle their interest in exploring fire and make them lose a good opportunity to learn and learn to protect themselves; On the other hand, I also understand parents' feelings very well, so I combined "where is the air?" Designed such a class. Mainly let children know that the burning of candles needs oxygen in the air by exploring and observing some interesting phenomena when candles burn. More importantly, it protects children's desire to explore knowledge.
2. Activity objectives
1. Observe the candle burning and find many interesting phenomena
2. Have an interest in observation and get a preliminary understanding of the relationship between burning and air
3. Cultivate children's interest in exploration and observation.
Third, activity preparation
Each person has a glass, a candle, a piece of drawing paper, a plate of paint and a piece of broken wax.
IV. Activity process
(1) Activity introduction
1. Teacher: The power went out last night, and the room was dark, so I couldn't see anything. What should I do?
(Children freely answer) Candles can illuminate. Today, I brought many kinds of candles for children to have a look.
2. What candles are there for children to observe and speak?
(craft candles, festive candles, cup candles, birthday candles, etc.) Where have you seen them? Where will these candles be used?
3. Summary: Candles can be used for lighting, crayons and wax paper.
(2) Burning candles
1 Observing burning candles
(1) Teacher: Candles can illuminate, and there are many phenomena in lighted candles (lighting candles). Let's see what color the flame of candles is. (children speak freely)
① The color of the candle flame is different between the middle and the outside, with a blue flame in the middle and a yellow flame outside.
② what is the flame of a candle like? (Children can imagine freely)
(2) Perceive the light and heat emitted by candles
① Ask a child to come and hold the flame with his hand, and tell me what it feels like.
② Teacher: When a candle burns, it will emit light and heat, and its flame will keep beating, up and down.
2. Experiment 1: Candle Burning in Air
(1) Teacher: Don't blow out the lighted candle, what will happen to it? What will happen to a lighted candle if it is covered with a glass? (Children speak freely and tell stories)
Next, I ask children to do an experiment to see what will happen.
(2) Children's operation experiment: (After the cup is covered, the candle will go out slowly)
① Why does the candle go out? (children speak freely)
② The candle goes out because it needs air when it burns. When the candle is covered with a cup, the outside air can't enter. When the air in the cup is burned out by the candle, the candle will go out.
③ After the cup is covered, the candle will go out. What else will happen? (The cup will be hot and black, and there will be small drops of water on the wall of the cup, and there will be a smell of smoke when the flame goes out)
3. Experiment 2: Water-absorbing Cup
(1) Teacher: What will happen if the lighted candle is placed in a plate filled with water and the glass is covered with wax? (Children discuss and speak)
(2) Children operate and observe the phenomenon
(3) Teacher: What did you see? Why did the candle go out and colored water was sucked into the cup? (Children discuss the reasons)
(4) Summary: After the lighted candle was put on the glass, the air in the glass was burned up by the lighted candle, and the atmospheric pressure in the glass became smaller.
4. Experiment 3: Candle Flowers
(1) Teacher: When a candle burns, a lot of candle oil will flow around it. The candle oil is like tears, and it is a little hot. Please put the candle oil in a plate filled with water.
(2) Children observe the phenomenon of candle drops in water.
(3) Summary: When a candle drops into the water, it will float on the water like a lotus leaf without sinking, so we gave it a nice name, "Candle Flower".
(3) Summary
Through the first experiment, observe the burning candle, let children know that the color of the candle is different in the middle and outside of the flame when it burns, and fully let children freely imagine what the flame looks like. So as to know that the candle will emit light and heat when burning.
