AYIMI AND THE MAIN GOALS IN EDUCATION

Journal Vol 3, No1, 2019, (P 3-7)

AYIMI is an international institute which is representing
of different international tournaments such as IYPT, IJSO,
ICYS and so on. In our experience, you need to be both
imaginative and practical in drawing up your research in
physics, chemistry, biology and other scientific fields and
this institute gives you the opportunity to learn basic
sciences practically. This network enables members also to
share information and exchange their own ideas on a wide
range of topics.

TO GET ELECTRICITY FROM THE PLAY TOOLS IN PARKS

The pollution crisis and the excessive use of fossil fuels
as energy sources have brought up many problems, such as
a variety of diseases, rising global temperature, melting of
polar ice and so on.
Fossil fuels are the driving force behind technological
progress. But the evacuation of fossil fuels and the
disastrous effects of excessive consumption have forced
humanity to rethink the use of fossil fuels as a source of
energy. Fossil fuels are capable of supplying the energy of
the whole world for several hundred years. The modern
world owes most of its technological progress to these
fuels. But unreasonable consumption of fossil fuels has
caused many problems around the world…

Water it is one of our most precious resources but our
water supplies a limited. 97.5 % of the earth’s water is salty
and only 2.5 % is fresh water but over two third of this fresh
water is locked in the polar ice caps and glaciers. This
leaves only 0.5 % in our lakes for agricultural, industrial
and personal use.

By shaking a container of liquid , it oscillates vertically
and the bubbles in the liquid moves too. When the
container moves up it makes the bubbles move down and
visaversa . Bubble moves downward more than it moves up
because of the smaller volume and smaller amount of water
it needs to replace , when it wants to move down. These
frequent phenomenon makes the bubble sinks.

One of the most important environmental issues in Iran is
desertification, which reduces the potential for biological
production of saline soils [1]. The high tensions in the
environment and soil of deserts and arid areas make
vegetation vulnerable. One of these tensions is salinity,
which negatively affects plant growth and weakens it. All
plants can’t withstand the salinity of the environment. A
few species can survive in these conditions. Therefore, the
vegetation of these areas is reduced..

Electrostatic motors are usually used in special
environments. Their non-magnetic fabrication and
structure simplicity make them have great potential for
limited, magnetic or other environments that
electromagnetic motors’ operation could be disturbed [1].
On the other hand, corona motors work with low
repulsive forces and the smaller their dimensions are, the
higher is their force per volume and thus, the higher would
be the output per unit weight [2]. Also, their insensitivity to
material properties and their ability to produce torque with
DC excitation makes them a possible interest in miniature
applications…

By connecting two loads, one heavy and one light, with a
string over a horizontal rod and lifting up the heavy load by
pulling down the light one we can observe that release the
light load will cause its sweeping around the rod, which
keeps the heavy load from falling to the ground (iypt.org).
So to investigate this phenomenon several experiments are
done . Accordingly, we will consider two major physical
principles; Archimedes Spiral and Newton’s Law of
Motion . By experiments we came to the conclusion that
the effective parameters are: weights’ masses, angle, width
of the bar, length and material of the string

Wooden Popsicle sticks can be joined together by
slightly bending and make a “cobra wave” chain. It was
seen that by increasing the length, in popsicle chain,
moving speed decreases. Also the thicker popsicle lead
higher speed. The elasticity (The Young’s modulus) and the
mass of the popsicle has effects on the height of the cobra
and the shape of the wave. The width will not change the
speed of the explosion. So we realized that it happens
because of the tension between the objects in this system
and some parameters which can affect on the structure of
curves like the distance between sticks, angle between
sticks, numbers of sticks and other parameters.

By angular velocity (ω) which shows frequency and
wave number (k), we obtain velocity (v) .In this
phenomenon important concepts such as Euler-Bernoulli
beam theory, dynamic stiffness, mechanical waves, wave
concepts and sound waves are considered . Wire diameter,
spring diameter, pitch of spring, and the free height of
spring are effective parameters.
