I am a teacher in the sixth grade of primary school. Please provide some jokes suitable for children. Rabbits buy carrots.

There is a little white rabbit who likes carrots very much and goes to the market to buy carrots every morning.

Come and eat. One day, the little white rabbit passed a drugstore on his way to Xiaobai Market.

Rabbit thinks pharmacies should sell carrots!

So he went into the drugstore and asked the boss:

White Rabbit: Boss, do you sell carrots?

Boss: No, carrots are going to the market. There are no carrots here.

The little white rabbit happily went to the market to buy carrots.

the next day

The rabbit went to the drugstore early the next morning and asked the boss.

White Rabbit: Boss, do you sell carrots?

Boss: Didn't you ask yesterday? Are you here to make trouble?

If you ask again, I'll cut off your long ears with scissors.

the third day

The little white rabbit went to the drugstore again and asked the boss.

White Rabbit: Boss, do you sell "scissors"?

Boss: No!

White Rabbit: Did you sell carrots?

This is a joke that our teacher told us before, but I just entered junior high school at that time. It seems a little old ~ ~

I am a new teacher, and the most important thing is to make students like you or not hate you. Children can't control their emotions. Once he (she) doesn't like a teacher, his first reaction is to hate the lessons taught by the teacher.

Secondly, we should educate our children in the right way. There are no students who can't teach well, only teachers who can't teach well. Even if the child is stupid, the teacher, as a professional educator, will definitely try to teach him or her. The key is to see how much effort teachers are willing to make for this major.

Finally, children's education is closely related to their parents. When you encounter a nail, you must first find out the reason and prescribe the right medicine.

I wish all the students in your class love you!

Xxx edition sixth grade primary school

Please do me a favor: I am a tutor in the sixth grade of primary school. My child is very naughty. How to improve children is mainly to encourage them. You promised to give him a reward, stimulate his interest, and then fulfill your promise and make him feel that you are very prestigious. Soon.

I am an honest boy. On a snowy day, the air is full of irises dancing with the wind. How beautiful! I didn't feel how cold it was, so I braved the snowstorm and ran to a stationery store. When I chose what I wanted, I found that I didn't have any money with me. I was shocked at once. what can I do?

The aunt who answered the phone seemed to see my problem and said gently, "little friend, did you forget to bring money?" It's not easy to run once in such cold weather. You'd better take the stationery back first, but give it back to me when you have time, hehe! " Aunt is so generous, I said, "OK, thank you!" " "So I went home. Two days later, the weather stopped and the sun came out.

Originally, I wanted to return it to my aunt at the stationery store, but then I thought: My mother usually buys it for me, and that person doesn't know me. Even if I don't pay her back now, she won't find me. I can buy a lot of things with this extra money!

Suddenly, the protagonist in an article "Little Wendy" dispelled my bad thoughts.

I remember Sandy selling matches in the street and asking a man to buy matches, but the man didn't bring any change. Sandy promised the gentleman to use matches first, but he didn't pay back the money for two days. On the third day, a little boy sent them. It turned out that this gentleman was hit by a car and was lying in the hospital. The gentleman paid back the money regardless of his life safety, and Sandy was moved to send it back later. Thought of here, I bowed my head in shame. I can't help myself. I hurried to the stationery store and returned the money to the aunt who collected the bill.

When my aunt saw me coming to pay back the money, she said happily to me, "Hey! Whose child are you? You are really an honest and trustworthy good student, and you will have a bright future! " I'm a little embarrassed. I always feel confused, but it's still sweet. How happy I felt on the way out of the shop.

Comments:

Through this incident, a profound truth is expressed to us: in life, as long as everyone learns to be honest from an early age, they will all be promising people in the future. I hope everyone is as trustworthy as the author.

Please provide the review materials for the second volume of science and the sixth volume of science in the sixth grade of primary school.

Unit 1: Small World

1. Magnifier can enlarge the image of an object, and you can see more details by observing the object with a magnifying glass.

Magnifier is widely used in many aspects of people's life and production.

3. Magnifier lenses are characterized by transparency, thick (convex) middle and thin edges.

4. The lens of the magnifying glass and the instrument that can enlarge have one common feature, that is, the middle is convex and transparent, so the magnifying glass is also called "convex lens".

5. The greater the convexity of the magnifying glass, the greater the magnification, so it is inferred that the magnification of spherical transparent objects is the largest.

6. Structure of magnifying glass: frame and lens (convex lens).

7. More details about insects can be observed through a magnifying glass, such as the compound eyes of flies; Crickets have ears on the inside of their feet; The colorful scales covered on the wings of butterflies are plain hair.

8. Like salt, sugar and monosodium glutamate, solid substances with regular geometric shapes are called crystals.

9. The combination of two convex lenses can enlarge the image of an object.

10, the invention of the microscope is a great leap for human beings to know the world, bringing human beings into the microscopic world. Microscope is an important observation tool for human beings to understand the microscopic world.

1 1, microorganisms were found in Leeuwenhoek.

12. Onion epidermis is composed of cells, and all living things are composed of cells.

13, the correct use of microscope: placement-aiming-loading-focusing-observation.

14, all living things are composed of cells, which are the most basic structural units and the most basic functional units of living things. The establishment of cell theory is considered as one of the three major discoveries of natural science in the19th century.

15, the morphology of cells is varied, and they have different functions.

16, microscopic micro-organisms invisible to the naked eye can be seen.

17, there are many different forms of microorganisms living in water. Such as paramecium and amoeba.

Microorganisms usually have special structures and functions to adapt to the surrounding environment.

19, microorganisms have biological characteristics, such as: have a certain demand for the environment, react to the outside world, and can reproduce.

20. Robert Hook first discovered the biological cell structure under the microscope, and Levin? Hook discovered a wonderful microbial world that was once unknown with his self-made microscope.

2 1. The achievements of human exploration of the tiny world have promoted the development of science and technology, the progress of society and the improvement of human life. Such as: anti-homogeneous diseases, brewing, pickles, dough making, yogurt making, biological cloning, garbage and sewage treatment.

22. Improvement of human observation tools: Smaller animals such as insects can see clearly with the naked eye.

Magnifying glasses can see things smaller than millimeters that are invisible to the naked eye.

Light microscope can clearly see cells and microorganisms.

The electron microscope can clearly see the atoms and molecules that make up smaller substances.

23. We can cultivate microorganisms with hay.

Unit 2 Material Change

1, the world is made of matter, matter is changing, and there are similarities and differences in the changes of matter.

2. The change of substance can be divided into physical change and chemical change, and the difference between them is that no new substance is produced.

3. The experiment of beans and sand did not change before and after mixing and separation, and did not change into or produce new substances. We call it physical change. Just as white sugar changes from white sugar to black carbon after heating, we call it chemical change.

4. Changes that can produce new substances in changes are called chemical changes, and those that cannot produce new substances are called physical changes. In the process of change, some substances will change both chemically and physically. Such as candle burning, sugar melting, heat discoloration www.x kb 1.co m.

5. Rice will change chemically when it interacts with saliva in the mouth: starch → maltose.

5. Starch and iodine will change chemically, and the new substance will be blue-purple. This characteristic can be used to test whether there is starch in food.

6. The mixing of baking soda and white vinegar produces a chemical reaction to produce a new substance-carbon dioxide gas, which is a chemical change. Characteristics of carbon dioxide: colorless and odorless, heavier than air, can put out fires.

7. Rust is a chemical change, and rust is a new substance different from iron. The reason why iron rusts is the result of the joint action of air and water: oxygen reacts with iron in an environment with water to produce iron oxide, which is rust.

8. In daily life, rust is the result of the interaction of water and air. Separating iron from water and air is a good way to prevent iron from rusting, such as painting and electroplating.

9. Chemical changes will be accompanied by various phenomena, such as discoloration, luminescence and heating, precipitation and gas generation. According to these phenomena, it can be preliminarily judged whether a substance has undergone chemical changes.

10, copper sulfate solution will react with nails to produce new substances.

1 1. The world around us is made up of matter, and matter is constantly changing. There are two kinds of material changes: physical changes and chemical changes. The most important feature of chemical change is the production of new substances.

Unit 3: The Universe

1, the moon is the satellite of the earth, and it rotates counterclockwise around the earth.

2. Lunar exploration process: naked eye observation-astronomical telescope-rover-lunar exploration.

The first manned spacecraft to land on the moon was Apollo 1 1 of the United States. Armstrong was the first man to leave footprints on the moon.

4. The moon phase is the various shapes of the moon in the changing process. The phase change of the moon is formed during the revolution of the moon around the earth, and the change is regular.

5, the moon phase is changing, and the change is regular. In the first half of the lunar calendar, it goes from missing to round, and in the second half, it goes from round to missing. (1, the moon phase changes through the process of new moon-first quarter moon-full moon-second quarter moon-waning moon. 2. In the first half of the month, the bright surface area of the moon gradually becomes larger until the full moon, and the bright surface is on the right side; In the second half of the month, the bright surface area of the moon gradually decreases until the new moon, and the bright surface is on the left. )

6. The moon is a non-luminous and opaque sphere, and the moonlight we see is the light it reflects the sunlight. The moon phase is actually the part of the moon that people see from the earth that is illuminated by the sun. Due to the different observation angles, the size and direction of the bright surface of the moon phase are also different.

7. The main feature of the lunar topography is the distribution of many craters, large and small.

8. The formation of craters is related to many factors, and meteorite impact is the main reason. It believes that craters are long-term traces left by meteors and meteorites. Because there is no air on the moon, it is equivalent to losing a layer of protection, which makes the impact more violent and frequent.

9. The moon runs between the sun and the earth, and the moon lives between the earth and the sun. The three are in a straight line, because the moon blocked the light from the sun on the earth, forming an eclipse. ：

A solar eclipse occurs when the moon enters the shadow of the earth, which is between the moon and the sun. The three are in a straight line, and the earth blocks the light from the sun to the moon.

10, solar eclipse may occur around the first day of the first lunar month, including total solar eclipse, partial solar eclipse and annular solar eclipse.

1 1, the lunar eclipse may occur around the 15th lunar month, including total lunar eclipse and partial lunar eclipse.

12. Eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

13, solar system: a celestial system centered on the sun, including eight planets and their satellites, dwarf planets and small celestial bodies (including asteroids, meteors and comets, etc. ). The first network of new curriculum standards

14, in order to facilitate identification, people divide the stars in the sky into a group and different regions, which are called constellations.

15, The Big Dipper is the main symbol of Ursa Major. Polaris can help you find your way at night. You can easily find it by using the Big Dipper in Ursa Major.

16, use the Big Dipper to find the North Star: extend the connection between the two stars at the front of the Big Dipper spoon. About five times the distance between the two stars, there is a brighter star, the Polaris. Polaris belongs to Ursa minor.

17. The most obvious symbol of Ursa major is the familiar Big Dipper, which consists of seven bright stars.

18, "Summer Triangle"-Tianjin IV. Vega and Altair; The main constellations in summer-Cygnus (Tianjin IV), Lyra (Weaver Girl), Eagle (Cowherd) and Scorpio (Antares).

19, the universe is moving and expanding, and so are the celestial bodies that make up the universe.

20, the solar system and many stars together to form a star group, called the Milky Way.

2 1. The Milky Way is not the whole universe. There are10 billion galaxies similar to the Milky Way, which are collectively called extragalactic galaxies.

22. The life of a star: the gas and dust in the nebula contract-the protostar-runs out of fuel, expands into a giant star or Supergiant star-explodes into a supernova-becomes a black hole or neutron star; Or the gas and dust in the nebula contract-the protostar-a small and medium-sized star becomes a red giant-the fuel runs out and contracts into a white dwarf-the energy runs out and becomes a black dwarf).

23. China is recognized as the birthplace of rockets in the world; China's space technology occupies an important position in the world; The manned spacecraft Shenzhou 5 and Shenzhou VI have realized the flying dream of China people. Now the Chang 'e-1 lunar exploration satellite has been successfully launched, and Chinese astronauts will also visit the moon in the near future.

The manned spacecraft "Shenzhou 5" was successfully launched from Jiuquan Satellite Launch Center on June 5438+ 10, 2003, and successfully returned on June 65438+ 10, 2003. The astronaut is Yang Liwei, who flew in space for about 2 1 hour.

Shenzhou VI manned spacecraft was successfully launched from Jiuquan Satellite Launch Center on June 5438+1October 65438+February, 2005, and successfully returned on June 5438+1October 65438+July, 2005. The astronauts were Fei and Nie Haisheng respectively. They flew in space for about 1 15 hours.

Unit 4: Environment and Us

1. At present, the main methods of garbage disposal are landfill and incineration, and simple landfill and incineration will also cause environmental pollution.

2. The harm of real landfill to the surrounding environment: it emits stench and pollutes the air; Breeding mosquitoes and flies, causing diseases; It causes soil pollution and affects agricultural production.

3. Advantages of burning garbage: small floor space, reducing the amount of garbage and avoiding groundwater pollution; Disadvantages will consume a lot of electricity, leaving residues and causing secondary pollution.

It is very important to reduce the amount of garbage, which is the way to solve the garbage problem from the source. The ways to reduce the amount of garbage are: reducing the discard and reuse of ww w.x kb 1.

5. What garbage can be reduced in daily life: (1) Double-sided printing can save paper. (2) Bring your own drinking cup to go out and buy less bottled drinks. (3) Use disposable goods as little as possible or not, and reduce the discarding of paper and plastic. ……

6. Excessive packaging will waste resources and produce a lot of garbage, and the abuse of plastic bags will also cause environmental pollution.

7. Some raw materials in garbage can be recycled, including paper, metal, plastic and glass. Recycling waste from garbage can save resources, energy, cost, garbage and pollution, which is a good thing without harm.

8. To recycle garbage effectively, we must change the habit of mixing garbage and classify and repackage domestic garbage.

9. Composting can effectively reduce garbage and form fertilizer.

10, China is a country short of water resources, and the total amount of water resources ranks sixth in the world. In terms of per capita water resources, the per capita possession is 2500 cubic meters, which is 1/4 of the world's per capita water, ranking 1 10 in the world, and being listed as one of the 13 water-poor countries by the United Nations.

1 1. The pollution sources of water may come from agricultural pesticides, chemical fertilizers, industrial wastewater, oil pollution, household detergents, human excreta and animal carcasses. It can be seen that water pollution is mainly caused by human activities.

12, sewage treatment is complicated, generally through three methods (physical method, biological method, chemical method) to get purification. The physical method is mainly to separate impurities and larger particles in water, including plastic bags, vegetables and weeds. The biological method is to decompose the dirt in water through bacteria; Disinfection mainly adopts chemical methods, and the usual practice is to add monochloro, a human chemical, to water, through which pathogenic microorganisms in water can be effectively killed.

13. At present, the prominent environmental problems include garbage, water pollution, air pollution, white pollution, accelerated species extinction and so on. Humans are paying attention to the corresponding environmental protection actions. 15. Establishing nature reserves is an effective way to protect biodiversity.

Hope to adopt! thank you

I am a sixth-grade primary school girl, with a height of 160cm and a weight of 1 12kg. Am I fat? 160 cm, 1 12 kg, not very fat. It should be normal, but you should keep it or increase it slightly in the future.

Math problems suitable for the sixth grade of primary school I have many math problems suitable for the sixth grade:

1. A sports meeting, in Class A, there are 15 people participating in the field events, 12 people participating in the track events, 7 people participating in both the field events and the track events, and 2 1 people not participating. So how many people are there in Class A?

2.6 1 class has 45 students. According to statistics, the situation of borrowing extracurricular books is as follows: all the students in the class borrow Chinese or math extracurricular books, 39 borrow Chinese extracurricular books and 32 borrow math extracurricular books. How many people borrow Chinese and math extracurricular books at the same time?

I am a primary school math teacher. I want to tell a sixth-grade student about the Olympic Mathematics. Where to start? I want to start with the most basic knowledge, so that I can understand the students' mastery of the basic knowledge.

It can also lay the foundation for what to say next.
