Topic 3:
How feels this or that? How seems this or that?
(Properties of the systems) |
1. Warming up (Card-index for the first grade)
2. Homework check up
3. Introduction to the lesson
"Yes-No game".
Deli-Davai gave a riddle
to Emil: there is a small object in a black box. What is it?
(Emil asked the Sorcerer
only three questions)
Draw inventive Emil. |
4. Main topic
Properties are the characteristics of the system that may be changed. By the properties it is possible to tell one system from the other. For example, all the systems have a common property: they can split into parts. |
Recognize it by description:
white, rectangular, small, leaves a trace: ___________________________white, thin, crumpling: _____________________________
round, pattern, jingle and crash: ________________________
rectungular,soft, erase traces of a pencil: _______________________
long, shiny, sharp, solid: ______________________
Each description suggests a few types of the systems in mind. It is important that a kid explains why he offers this system in particular.
To solve all the riddles
of the Sorcerer Deli-Davai you should remember about the changing
properties of the systems (Card-index for the first form).
5. Psychotechnical and developing games
The game we are going
to play now is called "Who does it or he resemble?"
Each of you has a picture
on the table with an animal. But I have picture with no animal on
it, no bird, no fish and no insect.
On my picture there is
a cloud, its name is Colabo. It has come to visit us specially for
our game.
Thus Colabo will play
only with somebody or something that looks like him. For example,
what does a dog and Colabo have in common?
- It is as
fluffy as a cloud.
- How about a rabbit?
- It is as white
as a rabbit.
- And what does
a rabbit have in common with a lion?
- They both have
round eyes.
- And who else
has round eyes?
- Actually all
do. Let's split into groups. Raise the card those who are hedgy.
Raise the cards those who are hairy. (We discover that every animal
has as a matter of fact nearly any property).
You choose the way to conduct a game taking consideration specific features of the class (individually, all together, in groups).Another way. You show the students simultaneously 3-4 cards depicting any systems and ask them to find an object that doesn't belong there. As a rule, it is possible to prove that any object might be crossed out. It is important that the kids should point out the properties that makes this particular system different from all the others.
6. Activities on speech skills developing
or producing the creative product
Today I have brought
for you very many maple leaves.
(The groups consisting 3-4 people get a heap of maple leaves.) Let's look at those leaves very attentively and try to find two identical leaves and two absolutely identical pattern drawings.
Well, what have we got? (We try to find the most subtle differences in the very similar maple leaves).
Let's sum up: there are no two absolutely identical objects; everything is unique. And any of you has your own world view and opinion about everything in the world.
Then, show me two leaves that are absolutely different.
(We find the most subtle features of resemblance of all the leaves.)
- All of them are
alike; all of them are from a maple tree.
- Well, of course.
It is impossible to find two objects in the world that have absolutely
nothing in common.
This activity may be performed at home with the parents.Knowing which properties our object have and what it resembles, we may devise many riddles about it.

Of course, to work with three tables at once is difficult for the kids. It's easier to use them one after one on different levels, thus repeating the topic of properties.
7. While summing up,
Do not ask the kids to give exact definitions to the properties. What is more important is that they should learn to find as many different properties of different systems as possible.
1. Warming-up. (The Card-index for the first grade)
2. Homework check-up.
The students who name the properties of the system under consideration may seat down.
3. Introduction to the lesson.
What properties may be found?
4. The main topic.
The system has plenty of properties. Let's consider in detail some of them:
Shape
There is a riddle devised
by Pythagoras before you.
Name the shapes that
you can see. Cut them neatly.
Color
It was very quiet in
the house. Emil, tired from games and lessons, decided to go to bed
earlier about 6 o'clock, and in order not to oversleep he set the
alarm at 7 a.m. as usual.
The night passed.
The alarm clock rang. Emil woke up, got dressed.
"How long have I been
sleeping?"- he thought.
And what do you think?...................................
Emil woke up very early
and saw a wonderful thing out of the window: color bow over the river.
What is it?
- Rainbow!
What does the rainbow
consist of?
Each - . Hunter - . Wish - . To know - . Where - . Sits - . Pheasant - . Draw a rainbow.
[Translation Note: The Russian words for the above phrase "Each Hunter Wish to Know Where Sits Pheasant" start with letters common with the words of the seven colors.]
6. Activities on speech skills developing
and producing the creative product
In this table there are
four properties by which you can identify any object. Look:
In order to show what kind of object it is, we will designate the size, color, form and temperature.1 - size; 2 - color; 3 - shape; 4 - temperature.
Now by moving the scale we can show which properties this mysterious object possesses. For example"
- Is it a bread?7. Summing up
- No.
- Is it a toy?
- No
- Is it animated?
- Yes.
- Is it a chicken?
- No.
- Is it a kitten?
- Yes. Good for you!
Find out whether the kids learned to use their knowledge about various system properties for solving problems.
