Search and cognitive directly educational activity for children of senior preschool age "Magic Stone - Magnet"
research project
"MAGIC STONE - MAGNET"
Relevance:
Experimentation- effective method knowledge of the laws and phenomena of the surrounding world is one of the most pressing problems of our time.
The main advantage of experimentation is that it gives children real ideas about the various aspects of the object being studied, about its relationship with other objects and the environment.
In children's experimentation, children's own activity is most powerfully manifested, aimed at obtaining new knowledge and information.
Experimentation is associated with all kinds of activities, such as observation and work, the development of speech, visual activity, FEMP.

Logic of educational activity
caregiver invites children to the hall designed as a scientific laboratory….
Asks the children the question - “Where did we come from?”
Children consider materials, “equipment”, offer an answer.
The teacher, using a hint (slides depicting a scientific laboratory), leads the children to the conclusion that they were in a research institute.
Asks children who works in research institutes and what people in this profession do.
Educator:- Guys! I invite you to visit our institute and become scientists-researchers for a while.
Offers to put on bathrobes, hats, glasses.
Draws the attention of children to the stand with the diagrams "Safety rules for working in the laboratory." Conducts a conversation "How to behave in a scientific laboratory." Learn the rules, assign roles.
The teacher acts as a senior researcher, since he has already visited this laboratory and knows what interesting things to do here. Children are offered the roles of junior employees and laboratory assistants and a badge with the appropriate designation.
caregiver brings in a box with a large magnet. The box is closed.
Today, some object was brought to our institute for research, try to guess what it is?
It happens small, big,
Iron is very friendly with him,
With him and the blind, without fail,
Find a needle in a haystack.
Children's answers...
Here we have an ordinary magnet.
He keeps many secrets in himself.
Educator: - " Our task is to get to know this amazing stone better.” Shows the magnet to the children, lets them touch it (what does it feel like? Smooth, cold), determine the weight (heavy - light?), color ...
Define - “A magnet is a stone, its surface is cold, smooth, has weight…..”.
caregiver asks the question - "What other property does a magnet have that distinguishes it from ordinary stones?"
Children's answers...
Educator: - " Guys, what do you think, are all objects attracted by a magnet? Children's answers.
To test your assumptions, I suggest that all junior employees and laboratory assistants go through to laboratory number 1 ...
- "Look what items are on your tables?"
Children list...
1. soft toy
2. wooden pencil
3. plastic button
4. glass jar
5. metal paperclip and washer.
Experience number 1.
“I suggest that you choose those objects that, in your opinion, a magnet can attract to itself.” The children are doing the...
How to check if you made the right choice? Children offer a solution to a problem(using a magnet).
- "What objects did the magnet attract?" (Clip, washer).
- "And which ones did not attract?" ( soft toy, wooden pencil, plastic button, glass ball).
« What conclusion can be drawn?
Conclusion: The magnet only attracts metal objects.
The study of the following properties of the magnet can be continued in laboratory No. 2.
The scheme “Repulsion and attraction of magnets” and airplanes with magnetic ends (red - blue) lie on the table and at the same time are shown on the screen.
Colleagues, pay attention to the scheme, what do you think, what research should we do? Children's answers...
The teacher draws the attention of the children to the magnet, painted in red and Blue colour. And also on the planes lying on the tables, with the same color. He asks why the magnet is painted in two colors? Children are reasoning ... Then the teacher offers to connect the airplanes with two identical ends. What's happening? (airplanes repel). If you connect with different ends - red and blue (airplanes are connected). Why? Children's answers ... The teacher gives an explanation: a magnet has two poles, if you connect two identical poles, then the magnets will repel, and if you connect two different ones, they will be attracted to each other.
Dynamic pause
The teacher offers to go to the airfield. - Look, I brought the planes you made: blue and red, like the poles of a magnet. Please note that our airfields also have two colors (red and blue). As soon as the music starts, you will fly in a circle, when the music stops, you need to land the plane on the airfield that will attract it. 2-3 children explain why the planes landed at a particular airfield.
Guys, look, there is some kind of vessel in laboratory No. 3, but you can’t see what is in it. But, in all likelihood, there is some kind of creature, possibly poisonous. How to find out who is in the bank without dropping your hands there?
Children's answers, discussion, guesses.
Let's try to get the inhabitant of the bank with a magnet?
Experience number 3. Get a snake out of the jar with a magnet.
Educator:- You have jars on your tables, in which there are snake-paper clips. Remove the paper clips from the jar with a magnet.
Educator:- Guys, what can you conclude?
Children:- The magnet works through the glass.
(Demonstration of the circuit through the projector).
- What do you think, does a magnet work only through glass?
Children's answers.
Experience number 4.
A track for cars is drawn on the easel, small metal cars and magnets are on the table. A magnet is installed behind the machine, which moves it along the track.
Now try it yourself. Take a typewriter, try to control them with a magnet.
What can be the conclusion?
- The magnet acts through the cardboard.
(Demonstration of all circuits through the projector at the same time).
Children are invited fisherman game. With magnetic fishing rods, children catch fish from aquariums.
At the end of the game, the following property is discussed: "A magnet works through water."
(Slide show).
The teacher draws the attention of the children to the box with the magnet.
Dear colleagues, today we had a difficult but interesting day. We studied the properties of a magnet.
What properties does a magnet have?
(Schemes are displayed on the board - hints).
Children name the properties and choose the appropriate scheme. (At the same time, the diagrams appear on the screen).
1. The magnet only attracts metal objects.
2. A magnet has two poles: different poles attract, and the same poles repel.
3. The magnet acts through glass, cardboard, water.
Children, together with the teacher, fold a magnet and cards, send a parcel with a completed task.
The child reads a poem about a magnet:
I have loved magnets for a long time.
He still beckons me
Small piece of stone
An inconspicuous, gray bar.
The teacher draws the children's attention to the screen « Practical use magnet."
The teacher orients the children to further familiarize themselves with the properties and use of the magnet. - How and where to find the information you need. Children provide answers. (Ask your parents, call relatives or friends, read an encyclopedia, watch TV, turn to Internet resources, etc.).
Dear junior staff and laboratory assistants, the leadership of the research institute thanks you for the work done and rewards you with valuable memorable gifts - magnetic games.

Educator: Dear guys, I’m glad to see you, you are so smart and beautiful and of course very funny and smart, so I hasten to tell you “Good morning!” (children's answers):
Invented by someone
Simple and wise
Say hello when meeting
- Good morning!
- Good morning, sun and birds!
- Good morning, smiling faces!
I really want everyone to have today Good morning and good afternoon. Let's join hands and give each other our smile. (greeting guests)
2. The game “Magic Gauntlet”
Educator: Now I see what you have good mood and Cinderella is upset and upset. the stepmother and her daughters went to the ball and left Cinderella at home alone and forced her to sort out the beans. Let's help Cinderella. How can we quickly sort out the beans? (I take out a mitten in which a magnet is hidden, put it on my hand).
I have a mitten, With it I'm just a craftswoman. Take a closer look
Follow my hand (I demonstrate a plate with beans and metal objects).
With the help of my “magic mitt” I will quickly sort through the beans (I cover the contents of the plate with the mitten, metal objects are magnetized to the mitten, and the beans remain in the plate).
Try to unravel this magic? (children's answers)
And I can tell you, these objects are magnetized.
We went through the beans and now Cinderella will have time for the ball.
And now, guys, I propose to listen to one old legend. (children sit on the mat)
In ancient times, on Mount Ida, a shepherd named Magnis was tending sheep. He noticed that his iron-lined sandals and a wooden stick with a metal tip stuck to black stones that lay in abundance under his feet. The shepherd took some of these stones home and amazed his neighbors. On behalf of the shepherd Magnis, the name magnet appeared.
There is another explanation for the word magnet by the name of the ancient city of Magnesia, where the ancient Greeks found these stones. Now this area is called Manisa and magnetic stones are still found there. Pieces of found stones are called natural magnets.
Over time, people learned to make magnets themselves by magnetizing pieces of iron.
3. Research laboratory
Educator: And now, guys, I invite you to become scientific researchers.
And who are scientists? (this is a person who studies something).
Scientists researchers begin their work with experiments and experiments. And we will also experiment and study the properties of magnets.
Now I invite you to the research laboratory, but first I will remind you of some rules. In the research laboratory, there should be silence and order on the tables, perform only those actions that are necessary (we put on badges with the word scientists, I invite you to go to the tables).
So the task is:
1. Examine the magnet and the objects on your tables in a plate, and determine what materials they are made of.
I will ask you to put the selected items on a separate plate.
Have you determined what material these items are made of?
What conclusion can we draw: which objects are not affected by the magnet and which ones are affected.
I propose to go to the guests and check what items they have magnetized (hairpins, fasteners, zippers)
Q. Does the magnet work through other materials? Let's check. Take a sheet of cardboard, put a paper clip on it, bring a magnet from the bottom of the cardboard. What's happening?
E. The paperclip follows the movement of the magnet.
IN: What moves a paperclip?
D: magnetic force.
IN: What can be the conclusion?
Conclusion: The magnetic force passes through the cardboard.
(Same with cloth)
C. Take a magnet and hold a paperclip close to it. What happened?
D. She magnetized
B. Take another paperclip and bring it to the first paperclip. (Two more paperclips). What's happening?
D. They are magnetized to each other.
Q. Now remove the magnet. What's happening?
E. Staples are holding onto each other.
IN: What can be the conclusion?
Conclusion: The magnet transferred its power to the paper clips for a while.
PHYSMINUTKA FISHING
B. Dropped paper clips into the water "accidentally"
Q. Guys, how to get a paper clip without getting your hands wet
D. children's version
In it is necessary to lead a magnet along the outside of the glass
What moves the paperclip
D Magnetic force
What conclusion can be drawn
CONCLUSION Magnetic force passes through glass.
IN: Guys, will magnetic forces pass through water?
D: Children's answers.
IN: Now we will check it. Dip one paperclip into a bowl of water. Swipe the magnet over the water.
(Children hold the magnet over the water, the paper clip at the bottom is attracted to the magnet).
IN: Guys, tell us what you did and what you got.
D: I held a magnet over a plate of water, and the paper clip lying in the water was attracted, magnetized,
IN: What can be the conclusion?
Conclusion: This means that magnetic forces pass through the water.
Guys, your magnets are painted in two colors blue and red - Every magnet, even the smallest one, has two poles - north and south. The north pole is usually painted blue, and the south pole is red.
Bring two magnets together.
Flip one of the magnets over and bring the magnets together again. What's happening?
In one case, the magnets attract, in the other they repel.
Poles of the same color repel, poles different colors are attracted.
The property of magnets to repel is used on railways in China and Japan. Some high-speed trains do not have wheels: powerful magnets are installed inside the train and on the rails, which are turned to each other with the same poles. Such trains practically fly over the rails and can reach tremendous speeds.

6. Game activity children with layouts "Autodrom"
Educator: Knowing the properties of a magnet, you can come up with interesting games to play. I invite you to the game room. I have prepared for you the game “Autodrom. With the help of magnets, you can move cars along the tracks of the autodrome. But before you start playing, let's remember what you have learned about the magnet and its properties, what you have learned.
This fairy tale is the first one, which I open in my blog with Tanya Tavika and her blog "It's interesting" project "Experiences and fairy tales". In it, Tanya will conduct an experiment on a chosen physical topic, and I will write a fairy tale.
The first theme we have chosen is Magnets.
« Dreams of one magnet»
On the table lay a large magnet and sighed. He was very bored. There is no one to grab and stick to him, and yet he has such a unique ability, And in vain the magnets inside him stood in rows exactly, like soldiers, and everyone looked in one direction, not moving.
Magnet was very proud of his magnets. He considered himself a little related to the world and his. After all, it also consisted of many tiny particles, only they, unlike the Svetiks, were obedient, stood quietly and calmly, did not fly anywhere, even looked in one direction. Any metal has such magnets, but everyone looks in different directions, does not obey. And here, such power! Because everyone is together. Once they grab someone, they won't let go. It's a pity that they can only grab iron.
What if you heat them up? Maybe then they will become stronger and begin to grab everyone and magnetize?
The thought almost made the magnet jump. Here is the idea! After all, it lies on a shelf near the stove itself. It is worth falling off the shelf, and he will be very close to the stove!
The magnet began to sway, ordered the magnets there, inside it, to also sway from side to side. After a while, the magnet crashed to the floor and tried to fall as close as possible to the stove.
Pleasant warmth spread throughout the magnet. He dreamily closed his eyes. But suddenly the noise and voices inside him disturbed the serene peace.
What did he see when he opened his eyes? Once obedient magnets were spinning in different directions, chatting with each other, and some even ran out of order!
What is, what is this mess? he shouted. But the magnetics did not pay any attention to his cry.
Just then the hostess entered the kitchen. She saw a magnet lying on the floor near the stove and threw up her hands.
Oops, now it's ruined!
The hostess quickly picked up the magnet and applied it to the cold iron faucet. But if before magnetists all together grabbed the proposed piece of iron, now many of them did not pay any attention to the crane. And when the hostess removed her hand, the magnet plopped into the sink.
What a disgrace! he sobbed, “it means that the heat does not help us, but, on the contrary, hinders us!” What will happen now? Will they throw me out?
The hostess twirled the magnet thoughtfully in her hands and put it on the shelf.
Let's see if it hasn't gone bad yet. Let it cool down, then we'll check it out.
Lying on a shelf, the magnet froze with fear. However, it cooled down, the temperature dropped. And the colder the magnet became, the more obedient the magnets became. They again lined up in rows and froze, looking together in one direction.
Wow, has it gone? muttered the magnet. “Never again will I dream of what I don’t have.” We attract iron, and good! Just great!
__________________________________________
Indeed, magnets are very interesting, almost magical ... objects? Well, yes, things. But they are almost alive!
And here are the experiences from Tanya. See how magnets can also repel, how to assemble small pieces of iron with their help, how ... Well, in general, read)
Experience 1. What materials does a magnet attract?
Let's take objects made of different materials: a piece of cloth, a piece of paper, a wooden toothpick, an iron clip, a stone, a glass ball. We will bring a magnet to them one by one. Which of these materials will be attracted to a magnet? experiments with magnets

Event progress:
Teacher: Hello guys! Let each of you put your hand to your heart, listen to how it beats. Did you listen? Hold hands and share some of the warmth and love from your heart from the palm of your hand to each other, smile each to your neighbor. Look into each other's eyes. Now look into my eyes, and I'll look into yours. In your eyes, I saw curiosity, a desire to communicate with me and my friends.
Knock on the door.
Guys, look what is this?
Package.
Let's find out who she is from. (The teacher twists the parcel, reads)
Parcel from grandfather Knowing. And grandfather Know we have such an inventor. There is a riddle in the box. To open the package, you need to solve the riddle:
I grab into a strong hug
Metal I brothers. (Magnet)
The teacher opens the package.
Guys, here is a letter for us: “Hello guys! I am sending you various objects and a gauntlet from my laboratory, but it is not simple, but magical. And what is its magic, you must determine for yourself.
But how can we be sure that the gauntlet is magic? (listen to the children's suggestions)
Experience No. 1 "Magic Gauntlet"
Let's try to put on a mitten and get items out of the package.
What happens to the items? (metal objects do not fall when unfolded, others fall. The gauntlet ceases to be magical).
Why is this happening? (there is something in the mitten that prevents metal objects from falling)
What can be in the glove?
(Let the children examine the mitten, there is a magnet in it).
Yes, there is indeed a magnet in our glove. Grandfather Know knowingly asked us a riddle about the magnet. He also sent magnets for you.
(Children sit at tables where they will experiment with magnets).
Pick up a magnet. Feel it, tap it with a magnet. What is a magnet to the touch?
(The magnet is hard, heavy, cold).
I have a magnet in my hand
He keeps many secrets in himself.
Important case experiment
Every moment is interesting.
I invite you to be little explorers today.
What do you think, where does the scientist begin the investigation? (from experiments, experiments) And today we will experiment and study the properties of a magnet. Examine the objects and determine what materials they are made of. How to do it? (listen to the children's suggestions)
What happens to these objects if you bring a magnet to them?
EXPERIENCE: Take turns bringing the magnet to the objects.
CONCLUSION: The magnet attracts iron objects. This is because a magnet is a piece of steel or iron that has the ability to attract iron objects.
Experience #2"Poles of a magnet"
Look at what a multi-colored magnet grandfather sent us Know. (the teacher takes out a magnet painted in two colors from the parcel: blue and red).
How is the magnet colored?
What do the colors mean? (indicate the poles of the magnet: blue - north, red - south).
Attach the magnets to each other with red ends, blue ends. What happens to them?
(Magnets repel).
Now attach the red and blue ends. What's happening?
(Magnets attract).
(The teacher leads the children to the conclusion that the differently colored ends of the magnet attract, and the same colored ends repel).
Guys, I really like to sew, but I have a problem, all my sewing accessories: buttons and buttons - everything is mixed up in the box.
How can you quickly disassemble everything, separate metal objects from plastic ones? (using magnets)
Experience #3
Children suggest using a magnet: it will attract all the iron parts, and the plastic ones will remain. They show how to do it.
Experience No. 4
The phone rings. In "Romance of the Turtle Tortilla"
Video call:
Hello dear guys! I'm in trouble! The favorite pond in which I live has been heavily polluted for three hundred years. There is a lot of rubbish in the bottom of it. Help me clean up the pond. Only one condition. You can't catch fish.
Well, what - let's help the turtle Tortilla and the inhabitants of the pond? How can we help her so that we do not disturb the inhabitants of the pond and get all the garbage? (listen to the children's suggestions)
Only our fishing rods are not simple, instead of hooks there are magnets.
Children take turns clearing the pond of debris.
From the aquarium, children use fishing rods with a magnet at the end to catch various metal debris.
What rubbish did we take out? Why only metal?
Because a magnet only attracts a metal object.
This is how you can do a good deed with a magnet!
Experience No. 5
Guys, the magnet is not only a wonderful assistant, he is also a wonderful artist. Do you agree?
He can draw"!
How do you think how?
Guys, look what shape my magnet is? (round)
How many circles? What circles?
What can be built from them? (children collect a tumbler)
EXPERIENCE: We will pour iron filings on the paper and put it on the constructed roly-poly.
CONCLUSION: Iron filings repeated the shape of the magnet. The magnet works through the paper.
What else can a magnet do?
Experience No. 6
See what's on our table? (paper clips)
What are staples made from? Let's check if they are attracted or not attracted?
I take a magnet, and you will bring a paper clip to it. She pulled herself up. Bring the second to the paperclip, it was also attracted, now - the third. A chain of staples formed. Now I will carefully take the first paperclip with my fingers and remove the magnet. Look carefully, the chain is not broken.
CONCLUSION: The paper clips, being next to the magnet, became magnetized and became magnets. But paper clips have magnetic properties for a short time.
I suggest you solve this problem. You have glasses of water on the tables, a paper clip at the bottom.
How to get a paper clip without getting your hands wet?
Experience No. 7: Bring the magnet to the glass.
What happened?
CONCLUSION: The magnetic force acts through water and glass. Therefore, we easily took out the paper clip without getting our hands wet.
Due to its ability to attract objects under water, a magnet is used in the construction of underwater structures.
Outcome.
Guys, did you like being scientists and doing experiments?
What did you learn about the properties of a magnet?
Who would you like to tell about working with a magnet?

Bozvanova Oksana Anatolyevna,
educator of the 1st category GBOU secondary school No. 38,
department preschool education children
Primorsky district of St. Petersburg
Amount of children: subgroup.
Target: the development of cognitive activity of children in the process of getting to know the properties of magnets.
Tasks:
Introduction to the concept of a magnet.
Formation of ideas about the properties of a magnet.
Updating knowledge about the use of the properties of a magnet by a person.
Formation of skills to acquire knowledge through practical experiments,
draw conclusions and generalizations.
Education skills of cooperation, mutual assistance.
1 Part:Introductory (informational and educational)
Educator: Hello guys!
Today we will go to the world of knowledge, discoveries, experiments and research.
We will learn with you what a Magnet is and get acquainted with its properties.
Guys, does anyone know what a magnet is? What is it made of? (children express their guesses).
Educator: A magnet is made from alloys that are capable of creating a magnetic field, mostly iron or steel.
Any magnet, any size, even the smallest one, has a north and south pole. Different poles attract each other, and like poles repel each other.
Children are invited to consider magnets of different shapes and sizes. (children examine magnets and try to experiment).
Part 2 Practical (experimental)
Educator: And now I invite you to the laboratory.
Who knows what a laboratory is? (children's answers).
Educator: in our laboratory, you can all experiment with the magnet and the various objects that are in front of you.
Educator: And for starters, I'll tell you why the magnet was called that.
According to an old legend, in ancient times on Mount Ida a shepherd named Magnis was tending sheep. He noticed that his sandals, lined with iron, and a wooden stick with an iron tip were sticking to the black stones that lay in abundance under his feet. The shepherd turned the stick upside down and made sure that the wood was not attracted by the strange stones. He took off his sandals and saw that bare feet were not attracted either. Magnis realized that these strange black stones did not recognize any other material than iron. The shepherd took several of these stones home and amazed his neighbors with this. On behalf of the shepherd, the name "magnet" appeared.
caregiver: Guys, do you like experiments? Yes.
Experience 1
What does a magnet not attract?
Children are offered: wood blocks, pieces of fabric, polyethylene, rubber, paper.
Conclusion: the magnet is not attracted to the body, paper, wood, fabric, polyethylene, plastic, rubber.
Experience 2
What is attracted to a magnet?
Everyone has paper clips, screws, nails, screws, coins on the table.
Conclusion: Paper clips, screws, nails, screws, coins are attracted to the magnet.
Experience 3
Can a magnet act through an obstacle?
Children are offered a glass of water, a paper clip and a magnet. Throw a paperclip into a glass of water. We lean the magnet against the glass at the level of the paper clip. After the paperclip approaches the wall of the glass, slowly move the magnet up the wall. The paperclip follows the movement of the magnet and rises up until it approaches the surface of the water.
(children conduct experiments and draw a conclusion).
Conclusion: The magnet can act through the obstacle.
Experience 4
Can a magnet act through other materials?
For experience are offered: paper, fabric, plastic, polyethylene.
Conclusion: the magnet can act through other materials.
Educator: Guys, let's play a little.
The game is called Magnet and Paperclips.
Purpose of the game:
I will be a magnet (show the children a magnet and how it interacts with paper clips), and you kids will be paper clips.
The command sounds: Magnet, turned on. Children run up from the paper clip to the magnet. The command sounds: Magnet, turned off. Children run away from the magnet, run in different directions and run.
The command sounds: Magnet, turned on, the children again resort to the magnet. (Repeat several times.)
Educator: well, now, we will continue to replenish our knowledge of the magnet.

Can a magnet magnetize other objects? (children conduct experiments and draw a conclusion).
In order to magnetize an iron object, for example, a paper clip, you need to rub the paper clip about 30 times on a magnet in the same direction.
Conclusion: A magnet can magnetize other objects. Around the magnet there is something with which it can act on objects at a distance. This is something called a "magnetic field".
Experience 6
Is it possible to create a magnetic field artificially?
Hang a paper clip from below with a strong magnet. If you bring another one to it, it turns out that the upper paper clip attracts the lower one.
For the experiment, a magnet and small and large paper clips are proposed. (children conduct an experiment and draw a conclusion).
Conclusion: magnetic field can be created artificially.
Educator: today we went to the world of knowledge and experiments, which means we are researchers. And explorers and travelers have a compass. The compass is a very important thing. And we don’t have a compass, but thanks to our new knowledge, we will be able to make it, and we will do it thanks to a magnet. We'll take a magnet and magnetize a nail, stick it to a round, flat piece of cork, and dip it into a cup of water. When the nail comes to rest, it will point north (there should be no other magnets nearby).
Our earth has magnetic poles that stretch from one pole to the other. As if in the very center of the planet we have a huge magnet moving. The compass needle detects the Earth's magnetic field and therefore always points north with its magnetized tip.
I really hope that you enjoyed learning new things, and now we know what a magnet is and its magical properties. You will be able to use your knowledge in the future.
