Kindergarten small class science bubbles are all round teaching reflection

Right. Because when the volume is the same, the surface area of the sphere is the smallest.

Are the bubbles all round, the lesson plan reflection is as follows:

Choose this science lesson "Are Bubbles Round?", I think this theme is very suitable for the age characteristics of the kindergarten children, and it is also very common in life, children are always interested in some games to play, children like colorful bubbles, and their curiosity about bubbles is also very heavy.

This lesson stimulates their curiosity and desire for knowledge, and encourages children to use their hands and brains to explore boldly, which is also the effect I hope to achieve.

Before the first activity, I asked the children to bring bubble equipment from home, and I found that the children brought it were mainly circles, which inhibited children's scientific exploration, constrained children's thinking development, and even formed a dynamic qualitative in the minds of some children: bubble equipment is round, and only round bubble equipment can play the game of blowing bubbles.

So I made different shapes of bubble utensils (triangles, squares, rectangles, circles) out of iron wire for children to explore and practice.

At the beginning of the activity, start with a game of blowing bubbles, let the children observe the shape of the bubbles, and then throw the question Can you blow a round bubble with a round utensil?

What shape of bubbles can be blown out of triangles, squares, and rectangles? Let the toddlers imagine for themselves. Then come back and ask the children to tell me what secrets they discovered while playing.

The children's interest was high, and when they experimented on their own, they found that bubbles were round no matter what shape of tool they were blown.

I asked them to talk about their experiments and record them. The whole class was still relatively pleasant and relaxing, but there were still some problems in the details of this activity, such as:

1) When preparing the record sheet, the lines are drawn too thinly, which affects the children's vision.

2) The successive presentation of props is not arranged.

3) Too many idiomatic phrases appear.

4) Finally, when arguing, if you make a mistake, you should ask the child to come up and argue by yourself, so as to strengthen the child's memory. Through this activity, I know that some details seem simple, but they should not be underestimated, and should be taken seriously.

Therefore, in the second activity, I learned from the last experience, in this activity, the children actively explored, the interest is strong, the children's problems are individual guidance, in the final argument, the wrong child is asked to come up to their own argument, observe the shape of the bubbles blown out by different shapes of instruments, let him find through his own arguments, no matter what stool Hui Qimo shape of the bubble blowing equipment, as long as the middle of the instrument is empty, the bubbles it blows out are round.

Although there were still a series of problems at the end of the second event, I will definitely learn from the experience and strive to be better next time.

The "Kindergarten Science Activity: Fun Water Bubbles" is designed to help toddlers distinguish between yellow and white and imitate the movements of small fish. Let's take a look.

Kindergarten Science Activity: Fun Water Bubbles

1. Teaching Objectives:

1.I like to listen to water bubbles, and I am willing to call to listen to the sound of water bubbling in the morning.

2.Try blowing out the blisters with straws of different thicknesses, perceiving many blisters.

2. Teaching Preparation:

blister sounds; small plastic transparent cups, straws (coarse, fine), plates; 1 transparent glass bottle and 2 plastic basins; Warm water, milk, fruit drinks.

3. Teaching process:

1) Listen to the sound, and the teacher imitates and reproduces the sound of "gurgling" water.

1.Listen to the sound of water bubbles and guide your child to recall what he has experienced: Listen, what is this sound?

2.Teachers use materials to imitate and reproduce the sound of blisters, which stimulates children's interest in making blister sounds.

b) Blowing water bubbles in the game, perceiving many bubbles and identifying yellow and white.

1.Provide materials to guide toddlers in making "gurgling" bubble sounds.

2.Guide the children to observe the phenomenon and conclude that whether it is a thick or thin straw, many blisters will be blown out.

3.Blow out colored beverage bubbles and perceive white and yellow.

a.Blow out white bubbles – milk bubbles.

Guide the toddler to think: what drink can be poured to blow white bubbles. Guide young children to experience the life experience of drinking milk.

b.Same as above, identify the yellow color and feel the yellow juice bubbles.

c) end the land strip section.

Listening to the music with the sound of water bubbles, the teacher guides the children to use their body movements and the sound of blowing bubbles to express the end of the scene of small fish swimming on the bottom of the sea.
