In this article we will talk about what are natural bodies and artificial, how do they differ. We give numerous examples with pictures. It is interesting to know the world around us, despite the fact that everything is very complicated. Itβs best to start small. For example, take a walk in the woods 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 in the left column the words "natural body", and on the right - "artificial body". In order to further consolidate the knowledge gained, it is recommended to pay attention to any objects at home and on the street.
What is a body?
Let's look at what artificial and natural bodies are. Grade 3 - these are children who are currently 9-10 years old. How can they explain what an object, a body in general? Everything is very simple. Any object is the body. What you can touch, 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, science, mathematics. The latter has the concept of "geometric body", that is, any figure. Next, we list natural bodies (examples). The world around us (Grade 3) is fertile ground for students to learn new concepts and laws of nature.
Let's be patient, because everything is not so difficult as it seems. And perceive the topic as a game. We love developing interesting games? Then let's start!
Go for a walk!
Where can you most often find natural bodies? Of course, on the street. If we go on a short trip to the mountains, the forest, to the sea or even to the field, then we will definitely meet them. We go first to the mountains.
The mountains
The mountain is a huge natural object. It was created by nature itself. A 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 a lot of stones, sand, when winter came and snow fell, flooded a hill for skiing. It is built manually or using machines, so it can be considered artificial. Every pebble, grain of sand on a mountain (even on a hill for riding) 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 canβt call them bodies, but a tree, bush, berries and fruits on them - you can. Dry branches on the ground, fallen leaves, hemp, despite the fact that they are not alive, remain natural, natural.
Sea
The whole beach is sandy or stone. You can find around shells, seaweed. Coral, fish, and jellyfish live in the sea. It is corals, algae, stones in the sea - all these are natural bodies. Examples of grade 3 (children will be happy to join this game) can lead to various. It is important to show any pictures. Students will list what is depicted on them.
Field
Here wheat or flax can grow, there are several trees, flowers. All this is natural, natural.
Bring home or to class
In children, you can develop a love of crafts made from natural materials. Some of them bring beautiful pebbles or a torn branch to the house. Of course, they are natural bodies. What will we talk about now? About what separate bodies the auxiliary material will consist of. Let's paint a square piece of cardboard in green, glue a few stones to it, a small piece of tree bark, an orange leaf. What do we get? Artificial cardboard, as it was made at the factory. Paint and glue are also not created by nature, they just can contain some natural components.
Consider still natural bodies. Examples (Grade 3) can be given completely different. It is recommended that you bring small objects, both artificial and natural, to the lesson. Suppose a pebble and a small piece of asphalt, 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, big
Which of the children can guess that whole 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 brilliantly. What cannot be done to man, she will do. Just imagine what small particles a mountain consists of. Every grain of sand, any, even the smallest pebble. It is impossible to make out the mountain bit by bit, and there is no need for this.
Admire the flowers in the meadow. Consider, for example, chamomile. How beautiful she is, all the petals are of the same shape, what is her fragrance. Can a man do exactly the same with his own hands? Practically, it will not work - natural bodies of nature so unique, complex in structure. And the plants are alive. They are able to multiply, grow, wither. Look now at the huge trees. Suppose two birch trees stand side by side, but they are completely different. They have knots and branches arranged in a chaotic order.
Object or body
Weβll talk more about how to distinguish a body from an object. Sometimes it can be called both one and the other word. Take up the small bronze bust of A.S. Pushkin. This thing is just a body. And now we will approach the monument, somewhere in the city. A huge bust on a pedestal (that is, a monument) is preferably called an object, because it is a landmark of the village and can be marked on the map. Agree that no one will call the object of the city a small bronze bust, which is in your home or in the classroom of a teacher of Russian language and literature. It can be added that cosmic bodies can also be called objects.
What the body consists of
Artificial and natural bodies can be of various shapes, sizes, each possessing its own properties and functions. As a rule, any body is a separate object, material. Absolutely everything consists of very small particles called molecules. This word will be often found in high school in chemistry, physics, and biology classes. And now it is desirable to have an idea that there are 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 incorporate the same types of molecules (or various), that is, substances.
Moving and motionless body
What natural bodies are able to move? Planets, comets, asteroids, satellites, stars. They are constantly in motion. But they are not all moving on their own, because they so wanted. They are helped by the physical forces that will be studied in high school. Now just give examples.
There are amazing things in nature: moving stones. How they can move, no one knows. But after all, there are simple stones that begin to move because a strong wind rose, a hurricane began or tremors appeared. The same applies to other bodies that do not move independently, something should help them in this. We are talking about inanimate objects. Now let's think about whether a tree or a flower is moving, a blade of grass. They canβt 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 item 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 launched. It would seem that in common between the moon and the ISS? The first has a spherical shape and is part of the Cosmos, and the second is assembled from 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 or vegetables bought or gathered from your garden).
Why natural bodies are needed
Answering this question, we pose another: can a person do without them? Above were mentioned fruits: fruits, vegetables. Without them, a person cannot be healthy. Grade 3 natural bodies - students - can be listed, but very little, because children are only just beginning to learn more deeply about the world. We will help them with this.
Any plant absorbs carbon dioxide, and emits oxygen. Thanks to them, we have enough air for proper breathing. Stones, sand, wood help build strong and durable homes.
A person should contact nature as often as possible and use its gifts. Only natural bodies help maintain health, strengthen immunity. Examples are as follows: any disease in the past centuries was treated with herbs, walked barefoot, breathed only fresh air.
What are artificial bodies for?
Can a modern person imagine life without things? Almost all of them are artificial, not natural bodies. Examples of such can be seen everywhere: at home, at school, in the store. Where and which bodies are most often found, we list below.
- At home . Wardrobe, chair, TV, keyboard, bag, toothbrush, chandelier, cutlery, flower vase and much more.
- At school . School desk, textbooks, pens and pencils, pointer, blackboard, door.
- In the shop. Cash register, food packaging, magazines.
- On the street . Wheel, car, traffic light, pole, booth.
You can list endlessly. Even in ancient times, people learned to create artificial things. Dishes and stationery have been around for a long time. But then such objects were made natural, because there were no factories and plants. Chemical industry and technology began to appear actively only from the end of the 19th century.
If artificial bodies did not exist
Let us imagine ourselves to be ancient people. Suppose a person does not have a phone, sofa, car. He is on the street like a wild beast. By the way, animals live in absolutely natural conditions. We are talking specifically about forest, marine inhabitants, 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 just bodies, moreover, natural bodies. A photo of this is presented below.
Nest on the branches, eggs with chicks - absolutely all of these bodies are natural, natural. Birds do not need incubators and cages.
But are fox holes, bear dens in general, bodies? No. These are objects, places where animals can fit to shelter from the 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 - 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 substances such as water, tea, juice, oil. We note immediately that they are not bodies. After all, these substances do not have their own form, you can not pick them up. A liquid also consists of molecules, like everything else.
Gaseous substances are oxygen, hydrogen, steam, even various odors from air fresheners, perfumes. Small particles, molecules, we do not see, but they are. Gas must not be touched, touched or seen.
Conclusion
This article told students what natural bodies are (examples). The world around 3 class (children) will be able to learn both with the teacher or parents, and independently. It is important that the lesson be held in the form of a game, and not consist only of definitions and concepts.
