In this article we will talk about what natural bodies and artificial ones are, how they differ. We give numerous examples with pictures. It is interesting to know the world around, despite the fact that everything is very difficult. It's best to start small. For example, take a walk in the forest or in the mountains, consider everything that surrounds. To make it easier to remember and understand, it is better to take a thin notebook, divide the pages in half and write the words "natural body" in the left column, and "artificial body" on the right. In order to further consolidate the acquired knowledge, it is recommended to pay attention to any objects at home and on the street.
What is the body?
Let's figure out what artificial and natural bodies are. Grade 3 - these are children who are currently 9-10 years old. How to explain to them what an object, a body in general, is? Everything is very simple. Any object is a body. What you can feel, see. The human body and the body in general are different concepts, so do not get confused. This word is generally accepted in the natural sciences, such as chemistry, physics, geography, biology, natural science, mathematics. Atthe last is the concept of "geometric body", that is, any figure. Next, we list the natural bodies (examples). The surrounding world (grade 3) is fertile ground for students to learn new concepts and laws of nature.
Let's be patient, it's not as hard as it seems. And we will perceive the study of the topic as a game. We love developing interesting games, don't we? Then let's get started!
Go for a walk
Where can you most often find natural natural bodies? Of course, on the street. If we go on a short trip to the mountains, the forest, to the sea or even in the field, then we will definitely meet them. Let's go to the mountains first.
Mountains
Mountain is a huge natural object. It was created by nature itself. Man could not build it in any way. Of course, there are also small slides, for example, for sledding. They are usually low. People in one place piled up a lot of stones, sand, when winter came and snow fell, they poured a hill for skiing. It is built manually or with the help of machines, so it can be considered artificial. Every pebble, grain of sand on the mountain (even on the hill for skiing) is a natural body. After all, the people who built the children's slide brought sand and stones from nature.
Forest
How many trees, ferns and mushrooms are around! There can be no artificial bodies in the forest, unless a person leaves a bag of garbage or some of his own thing.
Flying birds, insects, animals running through the forest are living creatures inspired. You can’t call them bodies, but a tree, a bush, berries and fruits on them can. Dry branches on the ground, fallen leaves, stumps, despite the fact that they are not alive, remain natural, natural.
Sea
The whole beach is sandy or rocky. You can find shells and algae around. Corals, fish, jellyfish live in the sea. It is corals, algae, stones in the sea - all these are natural bodies. Grade 3 examples (children will be happy to join this game) can give various examples. It is important to show any pictures. Students will list what is shown on them.
Field
Wheat or flax can grow here, there are several trees, flowers. All this is natural, natural.
Bring it home or to class
Children can develop a love for crafts made from natural materials. Some of them bring beautiful pebbles or a plucked branch into the house. Of course, they are natural bodies. What will be discussed now? About what separate bodies the auxiliary material will consist of. Let's paint a square piece of cardboard green, glue a few stones to it, a small piece of tree bark, an orange leaf. What do we get? The cardboard is artificial, as it was made at the factory. Paint and glue are also not created by nature, they just may contain some natural ingredients.
Let's consider natural bodies. Examples (Grade 3) can be given completely different. It is recommended to bring small objects, both artificial and natural, to the lesson. Suppose a pebble and a small pieceasph alt, a live violet and a plastic flower, a twig and a pencil, a leaf from a tree and a piece of paper. All of these items are visual examples. With children, you can arrange a game.
They are so big-very big
Which of the children can guess that entire planets and even the Sun are natural bodies? But any celestial objects are created by nature: comets, asteroids, stars, planets.
On Earth, trees, rocks, icebergs are also natural bodies. Nature arranged everything ingeniously. What a man cannot do, she will do. Just imagine what small particles the mountain consists of. Every grain of sand, any, even the smallest pebble. It is impossible to disassemble the mountain bit by bit, and there is no need for this.
Let's admire the flowers in the meadow. Consider, for example, chamomile. How beautiful she is, all the petals are the same shape, what a fragrance she has. Can a person create exactly the same with his own hands? In practice, it will not work - the natural bodies of nature are so unique, complex in structure. And the plants are alive. They are able to multiply, grow, wither. Look now at the huge trees. Let's say two birch trees stand side by side, but they are completely different. They have knots and twigs arranged in a chaotic manner.
Object or body
Let's talk more about how to distinguish a body from an object. Sometimes you can call both one and the other word. Let's pick up a small bronze bust of A. S. Pushkin. This thing is just a body. And now let's go tomonument, somewhere in the city. A huge bust on a pedestal (that is, a monument) is desirable to call an object, because it is a landmark of the settlement and can be marked on the map. Agree that a small bronze bust that stands in your home or in the classroom of a teacher of Russian language and literature, no one will call the object of the city. It can be added that cosmic bodies can also be called objects.
What the body is made of
Artificial and natural bodies can be of various shapes, sizes, each with its own properties and functions. As a rule, any body is some separate object, material. Everything is made up of very small particles called molecules. This word will often be found in high school at the lessons of chemistry, physics, biology. And now it is desirable to have an idea that there are also smaller substances that can only be seen with a powerful microscope.
Consider a small pebble - granite. It has several colors, but in fact it has various components, that is, molecules. They are different. Any natural and artificial bodies contain the same types of molecules (or different), that is, substances.
Moving and stationary body
What natural bodies are able to move? Planets, comets, asteroids, satellites, stars. They are constantly on the move. But they are not all moving on their own, because they so wanted to. They are helped by physical forces, which will be studied in seniorclasses. For now, just give examples.
There are amazing things in nature: moving stones. How they can move, no one knows. But there are also simple stones that begin to move because a strong wind has risen, a hurricane has begun, or tremors have appeared. The same applies to other bodies that do not move on their own, they should have something to help them with this. We are talking about inanimate objects. Now let's think about whether a tree or a flower, a blade of grass is moving. They cannot move, but they are able to grow, fold leaves and petals (if we are talking about flowers).
Artificial bodies
One word "artificial" already suggests that the object is made of plastic, plasticine or iron. Suppose that a natural satellite, the Moon, flies around the Earth. And besides it, there are many artificial satellites that people have launched. It would seem that what is common between the Moon and the ISS? The first has a spherical shape and is part of the Cosmos, and the second is made of metal, plastic, has its own specific tasks and is powered by fuel, solar energy.
At home there are many things of artificial origin: a bag, slippers, tubes and so on. Natural bodies are flowers, fruits (fruits, vegetables bought or picked from your garden).
Why natural bodies are needed
Answering this question, let's put another one: can a person do without them? Fruits were mentioned above: fruits, vegetables. Without them, a person cannot be he althy. Natural bodies grade 3 - students -can list, but very little, because children are just beginning to learn more deeply about the world. Let's help them with this.
Any plant absorbs carbon dioxide and releases oxygen. Thanks to them, we have enough air for full breathing. Stones, sand, wood help to build strong and durable houses.
A person should contact nature as often as possible, use its gifts. Only natural bodies help to maintain he alth, strengthen immunity. We give the following examples: any disease in the past centuries was treated with herbs, walked barefoot, breathed only fresh air.
What artificial bodies are for
Can a modern person imagine life without things? Almost all of them are artificial, not natural bodies. Examples of these can be seen everywhere: at home, at school, in the store. Where and what bodies are found most often, we list below.
- At home. Wardrobe, chair, TV, keyboard, package, toothbrush, chandelier, cutlery, flower vase and more.
- At school. Desk, textbooks, pens and pencils, pointer, blackboard, door.
- In the store. Cash register, food packaging, magazines.
- On the street. Wheel, car, traffic light, pole, booth.
The list is endless. Even in ancient times, people learned how to create artificial things. Dishes and writing instruments have existed for a long time. But then such items were made natural, because there were no factories and plants. Chemical industry andtechnology began to actively appear only from the end of the 19th century.
If artificial bodies didn't exist
Let's imagine ourselves as ancient people. Suppose that a person does not have a phone, a sofa, a car. He is on the street like a wild animal. By the way, animals live in absolutely natural conditions. We are talking about forest, marine life, birds. These creatures were born in natural conditions. Birds make nests from twigs, blades of grass. Raccoons, foxes, hares, moles dig holes.
Let's figure it out. A twig, a blade of grass, a nest - these are bodies, and natural bodies at that. A photo of one is presented below.
Nest on branches, eggs with chicks - absolutely all these bodies are natural, natural. Birds do not need incubators and cages.
Are fox holes, bear dens bodies at all? No. These are objects, places where animals can fit to hide from cold, rain and danger.
What does a person have? He is surrounded by household items, artificial things. Try at least one day to visit the natural environment and not take your phone with you. All the same, artificial objects will surround you - clothes, glasses (if any), watches, shoes. This means that a person cannot fully exist without all this.
Liquid and gaseous substances
Let's talk about things like water, tea, juice, oil. Note at once that they are not bodies. After all, these substances do not have their own form, you cannot pick them up. A liquid is also made up of molecules, like everything else.
Gaseous substances are oxygen, hydrogen, steam, even various smells from air fresheners, perfumes. Small particles, molecules, we do not see, but they are. Gas cannot be felt, touched or seen.
Conclusion
This article told schoolchildren what natural bodies are (examples). Grade 3 (children) will be able to learn the world around them both with a teacher or parents, and on their own. It is important that the lesson takes place in the form of a game, and does not consist only of definitions and concepts.
