Self-determination to activity
Look at the screen ... (slide 2)The slide shows different items.
(Shell, mittens, scissors, jug, ruler, spoon, scarf, mug, pencil)
Determine which "extra"? (shell)
Why? ( Shell - created by nature, and the rest were made by man)
What is the name of what is done by human hands? ( Man-made world)
Practical work.
Divide the rest of the items into groups by material. (Divide items into groups.)
All of these items are familiar to you. Name them and explain what they serve. What do all these items of the same group have in common? (They name the items. Tell them what they are for - from clay (vase, pot, brick, clay toy-whistle),
Wool (sweater, gloves, socks, scarf),
From metal (spoon, bowl, mug, scissors, metal constructor),
Made of wood (ruler, wooden spoon, matryoshka, notebook).
What will we talk about in the lesson? (We will find out what and how people make different products.)
Read the lesson topic in the tutorial.
Formulate the learning objectives that we will set ourselves? (we will talk about objects, find out what they are made of). Let's read about it in the tutorial.
Work on the topic of the lesson.
Conversation "What from what?" (Group work)
Now let's talk about each group of items separately.
1. Wool (consider a group of items made of wool ) (slide 3)
We have determined that these items are made of wool. Where does the wool come from?
(p. 111 of the textbook) Consider the drawings and tell how woolen things are made.
1. Shearing sheep;
2. Making wool yarn, winding on bobbins;
3. Manufacturing of woolen cloth;
4. Drawing on the fabric;
5. Manufacturing of clothing details by patterns.
What new things have you learned about woolen making?
How was this scarf made? How did you get the different colors?
2. Wood (consider a group of objects made of wood) (slide 4)
It is clear that the ruler and the stand are made of wood. But how did the notebook end up in this group? How did our textbooks come about? The guys who prepared the messages will help us figure this out.
a) Student speeches on papermaking.
There are different types of paper. Where is it used?
The plant produces paper.
- A writer writes a work.
- The artist makes illustrations
- The publishing house prints books.
- Books appear in the store.
Children's performance.
Today, paper is made in mills where machines help people.
Machines are taken to work even when the future paper grows in the forest. Electric saws saw, fell trees. Timber tractors carry logs to the river. The machines tie the logs into rafts, and the rafts float down the river to the gate of the workshop. Here other machines get down to business: a fast multi-sawing machine cuts logs into logs; a machine - a bark rips off the bark from them; the chipper chops wood chips into chips; the chips travel on a self-propelled track to the boiler. In a boiler, wooden porridge is cooked in a special solution. This porridge, when ready, becomes paper.
b) Display of a collection of different types of paper.
What is paper used for?
Is it easy to get paper? How should we treat our notebooks, textbooks, because all these are felled trees. And it takes at least 60 years to grow an adult tree.
They also make furniture, dishes, toys from wood. (Show.)
6.Fizzy
Now, guess who you are talking about? ( The music "Bu-ra-ti-no!")(slide5)
Why do you think we remembered about Pinocchio? (made of wood)
And from which fairy tale? ("Golden Key". A. Tolstoy)
7. Conversation "What is what?" (continued)
For a long time in Russia dishes were made from clay and such wonderful toys. (slide 6)
And how toys are made of clay, we learn from a fragment of the film .
(Viewing a fragment of the film "The Legacy of Philemon's Grandfather".)
A student's story about clay.
Clay is extracted in a quarry by excavators. In its raw form, it is plastic. It is mixed with water to form a thick paste, and then utensils or toys are molded from it. When dry, the clay hardens and becomes very strong. Then the products are fired in an oven at a high temperature of 450 ° C. After firing, the clay is hard and never soft. The art of doing such things is called ceramics.
In ancient times, when there were no refrigerators, clay jugs were used to store cold water. The water remained cold, as it seeped through the fine pores of the jug and evaporated, which helped keep the water cold.
The Chinese were remarkable potters. Made from special white clay porcelain... When fired, this clay becomes white. This cup is also made of clay.
I must say that bricks, toys, and tiles are made of clay.
In the last group, we had objects made of metal ... (slide 7)
A student's story about iron making
Nobody makes iron, it is created by nature itself, like water, clay, sand ... And people only extract this iron and turn it into cast iron and steel.
Iron is visible and invisible in the world - it is in the sand (that is why it is yellowish), and in reddish-brown clay, and in brown stone - flint. Iron is even dissolved in water.
Most iron is found in iron ores. It is from them that this most important metal is mined.
How is ore mined?
One cannot do without a huge, powerful, steel copal - a scoop, a small paper bag with an explosive charge and long wires. Miners will drill holes in the ground, lay explosives in them, and let current through the wires. Cover your ears here. As the explosion crashes - tons of earth, stones will fly into the air, scatter around, and the ore hidden under them will open. It happens that the ore itself has to be crushed by explosions. Finally, the explosions died down. A walking excavator is taken to work. The excavator will scoop up the ore with a bucket-scoop, turn around - and a whole wagon or a giant dump truck is loaded. But the ore was brought to the plant. How do you turn it into iron? A hot fire helps people here. In huge, like high-rise buildings, furnaces - blast furnaces day and night raging fire. To the very top of one such domain, trolleys crawled along an inclined road. They rise, overturn, pour the load into the oven - and down. In some trolleys, ore, in others - white stone, limestone, in others - fuel, dark gray spongy coke. It is, like a pie, baked from the finest coal, ground into flour. Well, limestone helps coke to pull out all excess impurities from the ore.
The coke burns hot, but it cannot melt the ore. To make it burn even hotter, you need to constantly fan the fire, you need air, hot, incandescent. That is why there are several more towers next to the blast furnace. It is in them that the air heats up. Mighty fans drive air currents through the pipes, continuously fanning a firestorm in the blast furnaces. The flame is raging, the ore melts, the ore settles, the drops of cast iron metal gather in trickles, rivulets ... The cast iron is heavy, it flows down to the bottom of the furnace, and everything that was in the ore rises, floats up in bubbly fiery foam. This is slag.
Finally, the master gives a signal: “Cast iron is ready! You can release melt. " A minute, another ... and, scattering fountains of sparks, illuminating the sky with a fiery glow, liquid metal will pour into a huge ladle. There are many buckets, each on wheels. There is a whole cast iron train on the rails. One bucket will fill, immediately the next one will fit under the stream. Where will the fire-breathing train go? His way is not far away - to the neighboring workshop. Here the cast iron will be poured into molds. In them, the liquid metal will solidify and take the form of the same form in which it was poured. And we meet with cast iron every day. After all, ordinary pans, cast iron, radiators, grates, into which streams on the streets run away - all this is also cast from cast iron.
So, we got acquainted with some of the materials from which a person can make the items he needs. And now, to consolidate, we will complete the tasks in the notebook.
Fastening (work in pairs):
Independent work on the "Workbook" p.39-40 №1,2
Show different production chains with arrows of different colors.
Write what people can transform these materials into.
(Grain, mill, bread. Iron ore, mill, scissors, etc.)
And besides clay, wood, metal, what materials can various objects be made of? (Plastic, rubber, glass, etc.)
What should people pay attention to when extracting various materials in nature for the manufacture of all kinds of products?
1) Obtain no more materials than is required.
2) Spend sparingly.
3) Plant new trees.
4) Recover land at the site of the quarries.
8. Lesson summary: (slide 8)
What question was answered in the lesson?
Who now knows what dishes, clothes, comfortable things can be made of?
For the manufacture of various things, a person mainly uses materials available in nature. But their supply is not unlimited. Therefore, a person should take good care of natural resources.
9.Reflection. (Slide 9)

10. Homework (slide 10)
WHAT OUR CLOTHES ARE MADE OF
Wool is collected for recycling hair animal cover ( sheep, goats, camels and others). The main useful property of wool materials for humans is that they have good heat-shielding properties, that is, they retain heat well. At the same time, they absorb moisture well. In winter, a person is very comfortable in woolen products.
Angora goats
Sheep, the main source of wool
Shorn
sheep wool
Factories use sheared animal hair to spin threads
The threads in factories are processed into fabrics or knitwear
Woolen fabrics
Coats, suits, trousers, etc. are sewn from fabrics in garment factories.
Boy's wool coat
Wool coat for girls
At knitwear factories, sweaters, blouses, tights and other products are knitted from woolen threads.
Wool sweater

Cotton is a fiber of vegetable
origin, covering cotton seeds.
Cotton materials absorb moisture well and give it away well. In summer, a person is very comfortable in cotton clothing.
But cotton does not have the same heat shielding properties as wool. Therefore, cotton products are more intended for summer.

Cotton
Cotton grows not everywhere, only in warm regions, so in ancient times, not all people knew the origin of cotton. Some thought that there are such plants that sheep grow on. Close to cotton and linen, which is called northern cotton
The cotton harvested in the fields is processed into threads in factories.
Textile factory
Cotton threads
Cotton threads are processed into fabrics or knitwear. Dresses, shirts, etc. are sewn from fabrics.

The threads that chemists make
Wool and cotton are natural materials. However, natural materials are not enough to dress all people on earth. Therefore, people learned to make threads using chemistry from wood and called them artificial.
These threads are close in properties to natural ones. The most famous of them are called viscose.
The threads that chemists make
Synthetic threads
Then people invented how to make different threads from oil and gas, including those similar to cotton and wool.
They are called synthetic. But in terms of properties, these materials are inferior to natural ones. They don't keep warm in winter as well as wool. And not as good as cotton, they give a feeling of comfort to a person in summer.

Teacher assessment
What do these subjects have in common?
What did man make these things out of?
Open the tutorial on
from. 108 and read the title of the topic.
- Since ancient times, people have had to adapt to living conditions in different conditions. Created by humans
tools of labor, dwellings and household items, clothing, ornaments were from the materials that were in that area. - The oldest are stone tools. Ancient people first used stone fragments, branches and twigs of trees. Scientists believe that the very first tool made by ancient man was a hand ax, carved out of stone.
- In our time, a person from the very birth of a person falls into the world of things. We are already so used to this that we don’t think about how and from what the objects around us are made.

2. Spend sparingly.
3. Plant new trees.
4. Reclaim land in place
quarries.
What should people pay attention to when extracting various materials in nature for the manufacture of all kinds of products?
– A person must use resources wisely. Natural resources must be protected, because they are not unlimited.
Making paper, a man cuts down forests, and they are “the lungs of our planet”, a home for animals and birds. After the extraction of clay, there are quarries that must be filled up, otherwise it is a wound on the surface of the earth. And if a person is unwise to use natural resources, then what can this lead to?
In every thing are invested
knowledge and work of many people,
so things must be treated
CAREFULLY!
