Scientific tips in life: 1. Why does sorbet get angry? The reason why sorbet bubbles is because there is a lot of invisible water vapor in the outside air. When it comes to cold sorbet, it will liquefy into droplets when it is cold. It seems that the sorbet is bubbling.
2. Why do sunflowers always face the sun? Sunflower stems contain a wonderful auxin. This auxin is very afraid of light.
When it is illuminated, it will go to the backlight side, and the cells on the backlight side will multiply rapidly. Therefore, the backlit side will grow faster than the bright side, which will bend the sunflower to light. 3. Why do cicadas shed their skin? Cicada's shell (exoskeleton) is hard and can't expand with the growth of cicada. When the cicada grows to a certain stage, the cicada's exoskeleton restricts its growth, and the cicada loses its original exoskeleton, which is cicada slough.
4. How do bees make honey? First, the bees spit the sweet juice of the flowers they picked into an empty hive. At night, they suck sweet juice into their honey stomachs to make it, and then spit it out and swallow it. It takes 65,438+000 ~ 240 times, and finally becomes sweet honey. The quartz clock hanging on the wall often stops when the battery is dead. This is because the second hand is most hindered by the large torque at the "9" position.
Science tip 6. Sometimes, when the water pipe discharges water from the nearby faucet, it occasionally makes a burst of noise. This is because the water pipe vibrates when the water rushes out of the tap.
7. When taking pictures on TV, turn off the camera flash and indoor lighting to make the picture clearer. Because the reflected light of flashlight and floodlight on TV screen will interfere with the transmitted light of TV picture. 8. At the same temperature, frozen meat thaws faster in water than in air.
At the same temperature, hot nails cool faster in water than in air. A cup filled with boiling water cools faster when immersed in water than when immersed in air at the same temperature.
All these phenomena show that water has better heat transfer than air. 9. When there is cold water in the pot, the water droplets attached to the outer surface of the pot bottom can only dry on the flame for a long time, and then they will boil. This is because the water droplets, the pot and the water in the pot keep heat conduction, and the temperature is similar. As long as the water in the pot is not boiled, the water droplets will not boil, but will evaporate on the flame and gradually dry up. 10, out-of-shape mirror, the farther away from the mirror, the more out of shape. Because the image in the mirror is formed by the reflection of the silver-plated surface behind the mirror, uneven silver-plated surface or uneven glass thickness will lead to aliasing.
Distorted mirror, the farther away from the mirror, according to the principle of light amplification, the larger the reflected light on the silver-plated surface deviates from the normal position, the more distorted the mirror is. . .
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 snake's muscles 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 will feel itchy and laugh constantly; 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.

4. Tips for children's health education
First, the basic content of health education 1, life health education.
The main purpose is to help children acquire necessary health knowledge in daily life, cultivate children's good living habits and gradually learn a healthy lifestyle. 2. Safety education.
Mainly to help children acquire and master the most basic safety knowledge and skills in daily life, so that children gradually know how to care for themselves and others, and constantly enhance their awareness and ability of self-protection. 3. Physical exercise.
Use sports equipment or natural objects for physical exercise to develop children's physical fitness in an all-round and coordinated way, enhance children's physical fitness and improve their ability to adapt to nature; Cultivate children's good psychological qualities such as being brave and not afraid of difficulties. 4. Mental health education.
Cultivate children's good psychological quality, enhance their own psychological strength and improve their adaptability to social life. Including: emotional education; Cultivation of good personality.
Second, choose the appropriate educational methods. The "Outline" requires that "we should not only attach great importance to and meet children's needs for protection and care, but also respect and meet their growing independent needs, avoid excessive protection and arranged substitution, and encourage and guide children to take care of themselves and try independently."
1. Appropriate educational methods. (1) Children's personal perception experience.
(2) Practice some life skills and healthy behaviors to form stable behavior habits. 2. Diversified forms of education.
(1) Organic infiltration in children's daily life. Children's health education is life education. It is necessary to infiltrate the concept of health education and implement health education strategies in all aspects of children's daily life, such as washing, eating, cleaning, sleeping and playing.
For example, let children know the importance of hygiene when washing their hands; You should know how to protect yourself when you swing and slide in outdoor activities. (2) Organic integration of all fields of education.
For example, when painting, you should learn the correct sitting posture and pen posture, and paint in the right way; Cultivate children to express boldly in language activities and develop interpersonal skills. . .
I have collected some scientific knowledge. I know:
I know: during the day, birds chirp in the branches and fly freely under the blue sky. At night, they should rest, sleep and recover their strength like us, but the sleeping posture is different! Beautiful mallard ducks and swans hunt and play in the water during the day, but they can't rest when they leave their favorite water at night.
They bend their beautiful long necks, bury their heads in their wings, and then let themselves float on the water, dreaming a beautiful dream, drifting with the tide, very leisurely. Long-legged birds such as cranes, storks and herons always sleep independently on one foot, and when they are tired, they change their other feet, which is a model of combining work and rest.
Partridges like to form a big circle in groups when resting, and then their heads are outward and their tails are inward. In this way, no matter which direction the enemy attacks, they can find and escape in time.
Birds with sweet voices, such as blackbirds and larks, usually bend their legs when sleeping, and their claws bend to firmly grasp the branches without worrying about falling from the trees. And the owl, a "night-shift" raptor, you can always see it standing on a dense branch with one eye open during the day, actually sleeping.
Isn't the owl's sleeping position very different? Is to always monitor the surrounding environment and guard against enemy attacks! .

What are the three parts of sunlight? Among the eight planets, Jupiter is the largest freshwater lake in China and the first of the five mountains in Poyang Lake. The rotation of Mount Tai is around the earth axis passing through the north and south poles, and the direction is from west to east. The farther away from the poles, the faster the speed. The largest mammal in the world is the blue whale. Which city is called the foggy capital of the world? 2 1 what is the main energy source in London in the century? What kind of pollution is called windmill power generation kingdom in Denmark? What kind of pollution is called the world's number one killer? Which country's Mercury Green Mud Observatory is the closest planet to the sun? Dry ice in Britain is carbon dioxide. Bi Sheng of China invented movable type printing in the Northern Song Dynasty. Why is China a land power? It is also a maritime power. With a vast territory of 9.6 million square kilometers, China is the largest country in Asia and one of the largest countries in the world, ranking third in the world after Russian and Canadian countries.
The coastline of Chinese mainland starts from the mouth of Yalu River in the north and ends at the mouth of Beilun River in the south, with a total length of18,000 kilometers and an island coastline of more than 32,000 kilometers. There are more than 6,500 islands; According to the relevant provisions of the United Nations Convention on the Law of the Sea and China's proposition, the sea area under the jurisdiction of China is about 3 million square kilometers. China has vast sea areas and abundant resources, so China is also a maritime power.
Why is space junk so harmful? They have become potential killers of satellites and orbiting space stations, seriously threatening the safety of astronauts. You know, space junk runs at the speed of the universe.
An oncoming metal particle with a diameter of 0.5 mm is enough to pierce the sealed flight suit; Dust that people can't distinguish with the naked eye (such as paint chips and paint powder) can also kill astronauts; A fragment the size of an aspirin tablet can "paralyze" a satellite and send a spacecraft costing hundreds of millions of dollars into a dead end. Because of the huge amount of tiny space debris, it will seriously change the surface performance of spacecraft; Slightly larger space debris will damage the surface materials of spacecraft, cause impact pits and damage surface devices; The high-speed impact of space debris will vaporize itself and the surface material of the spacecraft being hit into plasma clouds, which will eventually lead to the failure of the spacecraft.
Interesting technology once, Newton was so absorbed in his experiment in the laboratory that he forgot the time to eat. His assistant took some eggs and sent them to the laboratory. He said to Newton, "Here are some eggs. Do it yourself. "
Newton said, "OK, thank you. Please put the eggs there. " After that, he immersed himself in the experiment.
After a long time, Newton was hungry and remembered that he hadn't had lunch yet. So, he took a small pot, put the eggs in the pot, put them on the stove, and began to do experiments again.
Half an hour later, Newton finished the experiment. At this moment, he remembered the eggs in the pot.
He opened the lid and found there were no eggs in it, only a pocket watch. Newton was surprised and looked up. The eggs are still on the table, but the pocket watch on the table is missing.
It turned out that Newton was absorbed in the experiment and cooked the pocket watch as an egg. 1, who knows how the sea freezes? Everyone thinks that the sea water is salty and won't freeze.
In fact, after the temperature is lowered, the solubility of water will also decrease, that is, salt will be precipitated. In this way, the water freezes.
2. Who knows if Altair has it now? What we are seeing now is the "light" it gave off a long time ago. As for whether it exists now, only people in the Altair galaxy know that the light we observe from the earth is still the light from a stable star.
In addition, the average life span of stars exceeds 6 billion years. So now the solar cell phone battery that Altair should still exist has come out. This kind of battery is a combination of ordinary lithium battery and other solar cells. Technicians stick a thin layer of crystalline silicon photoelectric conversion sheet on the back of lithium battery. Single crystal silicon receives the current generated by illumination and charges the lithium battery through the protection circuit. In fact, as long as there is light outside the sun, the solar cell phone battery can be automatically charged, and no matter how long the exposure time is, it will not be overcharged because of the holding circuit.
Although it is introduced, this battery can generate 1 minute of electricity when exposed to the sun for 5 minutes, and it can also be used for two or three days when exposed to a desk lamp for one night. In addition, this kind of battery also has the function of ordinary mobile phone battery. If the light is weak, you can use the mobile phone charger to charge.
Sandstorm Sandstorm is a disastrous weather phenomenon in which wind and sand interact. Its formation is closely related to global greenhouse effect, El Nino phenomenon, sharp decline of forests, vegetation destruction, species extinction, climate anomalies and other factors. Among them, overexploitation, excessive logging and excessive reclamation of natural resources caused by population expansion are the main reasons for sandstorms.
As a kind of high temperature disaster, sandstorm does not happen in all windy places. Sandstorms only occur in areas with dry climate and sparse vegetation. * * * The topsoil of the land is easily rolled up by a big storm to form a sandstorm or even a strong sandstorm. Sandstorms do no less harm to people and buildings than typhoons and tornadoes.
Recently, sandstorms have appeared in northwest and even northeast China, especially in northwest China, which has been hit by sandstorms for more than 20 times. Why is the air by the sea so fresh? The waves constantly beat the coast every day, and the tides rise and fall, bringing beautiful scenery, pleasant waves and humid coastal air to the coastal area.
The air in the seashore contains a lot of negative oxygen ions, which are called "air vitamins". They can enter the human body through breathing, improve the ventilation function of the lungs, and increase the inhalation of oxygen and the exhalation of carbon dioxide. In urban public places, negative oxygen ions 10-20 per cubic centimeter, indoor 40-50, green lawn 100-200, and coastal 100000, which are hundreds of times more than indoor ones! Negative oxygen ions are negatively charged ions, which have bactericidal effect and can inhibit the reproduction of bacteria in the air.
A large number of negative oxygen ions improve the function of human sympathetic nerve, make people refreshed and energetic, and also increase the content of hemoglobin in blood. Therefore, there are many sanatoriums on the seashore, because the seashore air has a therapeutic effect on people suffering from emphysema, hypertension, neurasthenia, asthma, anemia and other diseases, which is beneficial to human health and makes people refreshed.
7. What parenting knowledge does the kindergarten class have?
First, educate children not to retreat for progress. Tell the child that when sliding backwards, the head will land first, so that all the impact of sliding down will be borne by the head. Coupled with the violent impact with the ground, it will cause a concussion, but it will scratch the scalp and cause a lot of bleeding.
2. Tell children that their bone tissue is soft and deformed under the action of external force. When children slide backwards, the cervical vertebrae will be severely squeezed, which may cause the vertebrae to deform and affect the growth and development. It is suggested that the skeleton model can be demonstrated to children.
Second, the method of teaching children to swing correctly 1. Keep the center of gravity stable and move it back as far as possible. Because when the swing swings in the air, if the center is unstable, it may be thrown out again.
Teachers can demonstrate and explain. 2. When sitting on the swing, grab the rope of the swing with both hands, as long as the rope keeps on, it will be safe.
3. When watching other children play on the swing, learn to dodge and don't be hit by the swing. When the children are playing on the swing, the teacher should pay close attention to the children's movements to prevent them from falling off their hands.
Third, teach children to cross the road safely 1, teach children to know the crosswalk line: the crosswalk line is a sign on the road and a special place for pedestrians and bicycles to cross the road. Therefore, you can't cross the road from anywhere, only the crosswalk can cross.
2. Introduce the function of traffic lights to children. Let the children know that the red light stops and the green light goes; When crossing the road, look around. When you see a car, pedestrians have to give way.
3. Simply tell the children about the role of roads: roads are places where all kinds of vehicles and people walk. Don't stay or play on the road, otherwise it will not only affect the normal traffic of vehicles, but also cause car accidents, ranging from disability to death. Iv. Safety precautions for outdoor activities 1. Teach children to dress neatly before activities, tie their clothes on their trousers and tie their shoelaces to prevent wrestling. 2. Educate children to know safety, understand what danger is and explain preventive measures.
3. Teach children to make their own toys by using movable appliances correctly. 4. Teach children not to carry out activities in crowded, potholed and damp places.
5. Educate children not to hide in unattended places at will in the game. 6. Educate children not to push, pull and throw things at each other in the game.
7. When playing with ropes, teach children not to put ropes around their necks. 8. When playing crawling activities, ask children to hold hands tightly when climbing, and don't push others.
Pay attention to the main points when you get separated from adults or get lost. 1. You should take motion sickness medicine before taking the bus to prevent motion sickness. 2. When you take the bus, you should queue up to get on the bus, without pushing or squeezing.
3. Pay attention to pull the handrail when riding to prevent the vehicle from wrestling when turning. Don't shout when you see a thief stealing from people around you in the car. You should tell the conductor or the driver's uncle to drive the car directly to the public security bureau, or tell the stolen person softly to prevent the thief from hurting the child, but remember to move quickly and don't let the thief notice.
Attention to parents: 1. Prepare a small schoolbag for the baby. Don't forget to embroider the name. You can put your baby's favorite little book or toy in it. Familiar items will reduce the psychological pressure of the baby in a strange environment. 2. Embroider the name or logo on the baby's clothes, shoes and other items to let the baby know and let the baby distinguish his own items in the collective life.
Prepare one or two sets of clean clothes and trousers for the baby, and remember to write down your name and put it in the kindergarten. Babies often wet their pants because of anxiety or playfulness, so that teachers can change clean clothes and pants for their babies in time.
4. When choosing clothes and shoes for your baby, don't be too novel * * *, small pockets that scream, bright shoes and interesting beads. These things will focus the baby's attention there, affect the baby's interest in participating in group activities, and some still have some unsafe factors. For example, falling beads, babies like to put in their mouths and ears.
5. Shoes should be the right size, suitable for the baby's sports as much as possible, and ensure the baby's safety in group activities. 6. When the baby has not learned to tie his shoelaces, try to wear shoes with shoelaces as little as possible. If the shoelaces are loose, the baby will easily fall down.
You can choose zipper shoes or shoes with rings. 7. Don't forget to prepare a safety pin for your baby and give him a clean handkerchief every day.
8. Try not to hang pendants, gold locks, bracelets, etc. For your children. These items will bring inconvenience to the baby's activities, and at the same time, there are also unsafe factors. 9. Guide the baby to try to take off his shoes and trousers, and don't forget to praise his progress from time to time.
