2016-02-26, 11:37:44


Purpose:
- contribute to the development of children's cognitive activity, curiosity; to develop thinking operations.
Objectives:
- to systematize the knowledge of children about the magnet and its properties to attract subjects; to acquaint the children with the phenomenon of terrestrial magnetism, the poles of the magnet, with the properties of magnets.
- to encourage the autonomy and activity of children;
- to develop children's thinking skills, the ability to analyze and generalize, to enrich the vocabulary of children (magnetism magnetic poles, attraction) .
- to foster friendly relationships, the ability to work together; to develop communication skills.

The lesson
Educator. Guys, today the postman brought us a parcel. This package from the little man from Floral city. Let's see what it (takes the letter and reads it). "Hello, guys. I am writing to you Shorty Floral city. In the city we found an interesting stone, it lies in the package in a little box. We don't know what it's called, what it can bring: good or evil, how and where it can be applied in life. We wanted to ask know-it-alls, but he immediately went on an expedition. Help us to understand this, examine the stone and send us the answer. We wish you good luck! ".
The teacher takes out the stone from a little box, children consider and Express their assumption that it's a magnet.
Educator. Guys, today we are going to be for a while scientists. Who are the scientists?
The children are responsible.
Educator. Yes, scientists are a profession of people. These people do research in different subjects, natural phenomena, human body, create new medicines, plants, instruments etc. Now our team of scientists will explore the magic stone magnet.
Teacher: You said it was a magnet. If it's a magnet, what it the most important property (action?
Children. It attracts metal.
The educator brings to his demonstration the children's table and points at objects made from different materials (plastic, wood, rubber, glass, iron).
Educator. What objects will stick to a magnet?
Children. The magnet will stick to iron objects.
The teacher (checks the version of the guys) : So Shorty Floral city really found a magnet.
Children sit at tables.
Experience the  "Magnetic poles".


Teacher: each of you has a magnet. Let's peopleseem its different aspects magnet with magnet with its neighbor. Let's see what happens.
Children: Our magnets that incorporate, repel each other.
Teacher: That's Right. This is due to the poles of the magnets. On one side of a magnet "North" pole and "South". Where else can be the "South" and "North" poles.
Children: our planet Earth.
The teacher asks one child to show the globe the geographic poles of the Earth and to note the "South" pole of the red circle, and "North" in blue.
Teacher: Tell me, guys, our Earth is what shape?
Children: Round.
Teacher: why do people, objects, houses don't fall down with her?
Children: the Earth attracts all.
Teacher: the Earth as one big magnet that attracts all, it has a magnetism. It has, in addition to these geographic poles and magnetic poles. The magnetic poles do not coincide with the geographical poles (notes on the globe's magnetic "North" pole with a blue rectangle and the "South" – red) .
On your Desk there are magnets with marked poles. Try combining them with each other.
What do you see? When magnets attract, and when repel each other?
Children: When we combine the "North" and "South" poles, the magnets attract each other. North poles repel each other and the southern too.
Teacher: When we connect the magnets between the different poles of our magnets begin to make friends. But if we combine the same side – the poles, they run away from each other, don't want to be friends. Now we can define poles of the magnet was found with a magnet with marked poles. Let's try. Children define the edges.
EXPERIENCE No. 2 "Magnet is not afraid of obstacles".
Teacher: We learned that a magnet has a "North" and "South" poles. Now we need to know whether attracting force of a magnet on metal objects (paper clips):
A) wood,
cool paper,
cool plastic,
G) water.
The children noted that the action of the magnet on the paper clip through the wood, paper, plastic, water does not disappear.
EXPERIENCE No. 3 "Magnet turns the metal into itself."
Teacher: Guys, I have other clips that were five days on the magnet. Bring them to your paper clips. What's going on?
Children: attract Your staples our staples.
Teacher: Why are staples, too, like a magnet can attract metal? (listening to children) .
A magnet is a magical stone, he my staples gave a little of his strength. They become magnetized, they have a magnetism.
EXPERIENCE №4 "Magnet is afraid of fire".
The teacher provides through the holder heats the magnetized paper clip over a candle and brings them to his UN-clip.
Children have noticed that a magnetized paperclip has lost its power.
Teacher: When a magnet or magnetized metal objects heat up, they lose their power of attraction. The magnet is afraid of the heat. The fire takes away his magnetism.
PHYSICAL EXERCISES OF THE "MAGNETIC MEN"
Each child on his back hung a blue square, and the abdomen is red. They form a circle and begin to walk in a circle.
Teacher: When I show a red square – the South pole, you are attracted to me "the North pole" is back. When you see a blue square, you are attracted to me bellies – "South poles". The magnet is afraid of fire, high temperature, therefore, when you see a candle, then sit back on my heels and locked hands.
After a physical minutes the teacher invites the children to continue study.
EXPERIENCE No. 5 "Power of magnets"
The teacher invites children to determine which magnet is stronger. Listens to the suggestions of children, how to do it. Children it is not necessary to formulate their proposals verbally. The child can Express his thoughts clearly, working with objects needed for this, and the teacher, along with other helps to verbalize it.
The discussion reveals the way to compare the strength of magnets:
the number of paper clips – the stronger the magnet that holds your pole chain with a large number of steel clips.
Counting the number of paper clips at the poles of the magnets, and comparing them, the children find out who has the strongest magnet .
Thus, the clip in this case is the "yardstick" to measure the strength of the magnet.
The educator invites the children to consider pictures "Using magnets".
Educator. But the things with magnet have in our group?
Children. The magnet-mounts on a magnetic Board, magnetic letters and numbers.
Teacher: thank you, short floral city for his parcel for his job for us. What do you think, my dear young scientists, we coped with the task?
Children. Yes!
Teacher : what have we learned today? Who helped?
The children's responses.
Educator. We learned a lot about the magnet, helped the little man. Now we have to send our acquired knowledge and the magnet in Floral city.
The tutor promises to include a package in the mail.
