Now many parents not only carry out prenatal education early, but also make unremitting efforts in early education.

In order to meet the needs of parents, many early education institutions have been established in the market. However, the requirements of early education science should be determined according to the child's age and personality. If the method is not appropriate, it will bring certain negative effects to the child's physical and mental development.

Little knowledge that early education must understand 1. It is necessary to decide whether children can receive early education according to their actual age and ability range. Moreover, the way of early education depends on the child's personality. Not all early education methods are suitable for every child.

Therefore, it is necessary to analyze specific problems. Only by finding the right method and giving special education to children can we play the role of early education. 2. Early education is not as young as possible, and the content of education must be consistent with the age of children.

Advanced education may not necessarily make children smarter than their peers, and sometimes even cause physical and mental harm to children. There are many ways of early education, but it is not necessary to send children to early education institutions for early education. Family early education is also a very effective way of education. Parents can educate their children with life according to their actual situation.

This way of family early education can not only improve the efficiency of early education, but also play a great role in enhancing the affection between parents and children. .

2. Little scientific knowledge

Why do the stars twinkle? We see the stars shining, not because the luminosity of the stars has changed, but because of the occlusion of the atmosphere. The atmosphere is between us and the stars. When starlight passes through the atmosphere, it will be affected by the density and thickness of the atmosphere.

The atmosphere is not absolutely transparent, and its transparency will change according to its density. So when we look at the stars through it on the ground, we will see that the stars seem to be flashing.

2。 Why do people yawn? When we feel tired, a lot of carbon dioxide has been produced in our bodies.

When there is too much carbon dioxide, oxygen must be supplemented to balance the needs of the body. Because these residual carbon dioxide will affect our body's functional activities, then the body will send out a protective reaction, so we yawn.

Yawning is a deep breathing action, which will let us breathe in more oxygen and expel more carbon dioxide than usual, and it can also eliminate fatigue. 3。

Why can snakes walk without feet? Snakes have many scales, which are the outermost armor on their bodies. Scales are not only used to protect the body, but also to be their "feet".

When a snake crawls forward, its body will be S-shaped. Every scale outside the S-shape will tilt upward to help the snake catch the uneven road when it moves forward.

These scales cooperate with the muscles of the snake and can push the body forward, so the snake can walk without feet! 4。 Why do sunflowers always bloom towards the sun? There is a substance called "auxin" in the stem under the sunflower disk.

This substance has the function of accelerating replication, but it is anti-optical, and it will run to the backlight side whenever it encounters light. So when the sun rises, the stem of the sunflower immediately hides to the side of the backlight, as if the whole plant is bent in the direction of the sun.

5。 Why does the hair turn white when people are old? There is a substance called melanin in our hair. The more melanin, the darker our hair will be.

Without melanin, hair will turn yellow or white. When human beings reach old age, various functions of the body will gradually decline, and the formation of pigments will be less and less, so the hair will gradually turn white! 6。

Why do fireflies glow? Fireflies emit light because there is a luminous body at the end of their abdomen, which is filled with a lot of phosphorus-containing luminescent substances and luminescent enzymes, so that fireflies can emit flashing light. The purpose of fireflies is not only lighting, but also courtship, vigilance and trapping.

This is also a communication tool for them. Different kinds of fireflies emit light in different ways, frequencies and colors, so they can convey different information. 7。

Why do you growl when you are hungry? When you are hungry, you will purr. This is because the food you have eaten before has almost been digested. Although the stomach is empty, the gastric juice in the stomach will continue to secrete. At this time, the contraction of the stomach will gradually expand, and the liquid and gas inside will be stirred up and purr.

Don't be embarrassed by your stomach growling next time! Because this is a normal physiological action. 8。

Why can't ostriches fly? A giant ostrich, but they can't fly into the sky! This is not because their wings are useless, but because their feathers are too soft and their wings are too small to fly at all. In addition, the ostrich's muscles are underdeveloped and its sternum is flat, which is not conducive to flying.

Ostriches live in Africa. Because they have lived in desert areas for a long time, their bodies gradually evolved into what they are now in order to adapt to the environment. 9。

Why can't it go bad easily? Lunch meat, black bean shad, tomato sauce beans.

They are all delicious canned food, which can be preserved for a long time without deterioration. This is because the can is sealed, so bacteria can't enter.

When people make canned food, they pump all the air out of the canned food and then seal it. In the absence of air, even if the food inside is contaminated with a little bacteria, they can't survive or reproduce! 10。

Why do babies always cry at birth? Babies cry when they are born, not because they are unhappy, but because they are taking the first breath of air! When babies leave their mother's body and are born, the first breath of air will rush to their throats, violently impact the vocal cords, make them vibrate, and then make a sound similar to crying. 1 1。

Why do lizards keep playing backwards when their tails are broken? In order to protect themselves, many lizards also protect their eyes and ears; When some lizards are attacked, their tails will be broken due to the severe contraction of their muscles. Because there are still some nerves alive in the broken tail, it will keep bouncing, thus distracting the enemy and running away.

Don't think that their lives will end like this. In fact, it only takes a few months, and their tails will grow back and move on. 12。

Why is the squirrel's tail so big? Don't look at the relaxed mouse tail! When the squirrel jumps around the tree, its tail plays a great role. It can keep balance when the squirrel jumps to the tree to avoid falling and being injured.

In addition, this big tail can play a more protective role in winter, tightly surrounding the squirrel's body, which is convenient and practical. 13。

Why can't a person's thumb have one or three knots? The average person has five fingers, each with a different length. However, does anyone realize that besides the thumb, other fingers also have three sections, while the thumb alone has only two sections? It turns out that the number of joints is just the same as the other four fingers.

If it is three knots, the thumb will appear weak, so that it can't lift heavy objects; If there is only one section, it can't grasp things freely with the other four fingers! 14。 Why not tickle yourself? When others scratch ourselves, we feel itchy and laugh nonstop; However, when we scratch ourselves, we not only don't laugh, but also don't itch.

Based on our psychological preparation, the brain will send out a message that there is no danger, and the nerves will relax, so that they will not laugh and itch! 15。 Why is the sea mostly blue and green? Looking at the sea, it is often found that the sea water is blue-green.

However, when you pick up the sea water, you can only see it as transparent and colorless as old water. Original.

3. Kindergarten scientific parenting knowledge

When I chose a kindergarten for my son, there were three hardware conditions and several software conditions: three hard conditions: 1. Kindergartens have independent activity places (because many kindergartens are in the community, I will share an activity place with the community. If there is no independent activity place in the kindergarten, I will not consider it); 2. The division of functions in the classroom is very clear, such as sleeping area, activity area, reading area and manual area; Some cribs in kindergartens are moved around, so I don't think about it, which will make children feel cramped. 3. Do not consider running an experimental class kindergarten. There is no special difference between such a small child. Such a small child needs the teacher's love and patience. Running an experimental class kindergarten makes me feel like a kindergarten that doesn't understand children's naive nature. It is an over-commercialized kindergarten.

How can I believe that such a garden will protect the innocent hearts of children, so I will not choose. Software conditions: Because children are young, I feel that mental health is very important. I don't expect children to learn anything during kindergarten. I think I want to be mentally healthy enough, so I want to be happy, that is, eat well, drink well and have a good time. So I want to choose a kindergarten that feels patient with children. It would be better if the teacher had a little wisdom (as if this requirement were a little high), so patience is necessary. I went to seven kindergartens when I chose a kindergarten for my son. Every time you enter a park, one is to see whether the layout facilities in the park are considered from the perspective of children, and the other is to see the mental outlook of children in the park. The garden I chose for my son is the most active and happy one among all the gardens. In fact, it is a kindergarten run by people who know children better.

There is another angle, because every mother has different ideas. If you choose a kindergarten with the same cognition as you, your satisfaction will be high.

4. What scientific knowledge do preschool children need to popularize?

Children's science education refers to the exploration activities in which children perceive, observe and operate the world around them, find problems and seek answers through their own activities under the guidance of teachers. Different from simple knowledge teaching, it is more important to cultivate children's interest in scientific exploration and let them master scientific methods.

First, effective introduction can stimulate children's desire to explore. Second, the design of activity content reflects hierarchy 1. According to children's cognitive characteristics, arrange activities at different levels. 2, according to the child's development level, carefully design the problem.

Third, teachers carefully guide scientific activities 1, seize the interest of young children, and guide them in a timely and effective manner. 2. Give children a chance to start work and give full play to the effectiveness of exploration behavior.

3. Give timely evaluation to ensure the effectiveness of teacher-student interaction. 4. Pay attention to the effectiveness of resources 1, and appropriate materials and appropriate delivery methods are the key. 2. Give full play to the efficiency of modern educational technology.

5. What are the knowledge of kindergarten parenting?

What are the knowledge of kindergarten parenting?

Children in kindergarten classes are generally 5~6 years old. During this period, children's imitation ability and learning ability are relatively strong, and curiosity is also prominent at this time. So, today, let's take a look at the parenting knowledge of the kindergarten middle class.

Whether as a kindergarten or as a family, we should master the development characteristics of children in the following stages. Only in this way can we better master the relevant parenting knowledge.

Babies in this period are usually full of curiosity about the things around them, so children's attention is not concentrated and easy to disperse. In addition, the children in the middle class are prone to mood swings and willfulness.

Encourage children

This is very important for the children in the middle class, because they are still relatively dependent on the teacher, and it is easy to be afraid of difficulties and dare not try. Therefore, encouragement is particularly important at this time.

autonomous working

No matter how difficult it is, you can let your child try it first, and then praise it in time to fully establish your child's self-confidence. This not only cultivates children's good habit of hard work, but also cultivates children's good self-confidence.

Imitation ability

Children at this stage often have amazing imitation ability, which parents should not underestimate. Because this shows that children have strong curiosity and thirst for knowledge, and will pay attention to the characteristics of the objects they imitate, which is also a manifestation of self-ability.

Give play to subjective initiative

Most parents think that children don't know anything, so they advocate for their children no matter what. In fact, this is not conducive to their growth. As parents, we should let go of our children appropriately and let them play with their own choices. This is also to avoid indecision in the future.

Therefore, the education of children in kindergarten middle class should be cautious. First of all, we should understand children's personality characteristics. Secondly, we should seize the advantages of children and help them become better people.
