To find how scientific communities can encourage students to learn science in a friendly atmosphere and then combine scientific fields and arts to show the beauty of different solving problems by the creativity is explained in this report.
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. National and international awards are given to top participants in several activities from all over
the world every year which will bring our young talents even closer together.

TO GET ELECTRICITY FROM THE PLAY TOOLS IN PARKS

Many of children are busy playing in the parks and game fields every day, and a lot of the movement energy of the children are wasted, while this energy can be used appropriately. The purpose of this project is to use the rules of electromagnetic induction, by placing the magnet and the coil together and changing the gap between them which causes changing the magnetic flux so the induction driving force creates a flow of electricity that turning it into a luminous energy and lighting the park lights
will prevent waste of energy.

Aqua Optimizer is a device which has been designed to help people with using Awater in various background, including home use, especially in bathing. Three steps are defined for the device, each step indicates the amount of water consumed by the water in which the green, yellow and red lights are respectively lit when the water is being used, and if the user exceeds the limits then the device will cut off the stream and eventually prevents it from wasting the water.

This experiment is about the motion of the gas bubble in vertical oscillating fluids. Bubbles which are made on the surface, sink instead of rising in a tank with low viscosity liquid. When a container of liquid oscillates vertically it is possible that bubbles in the liquid move downwards instead of rising. This phenomenon was first observed in rockets engines. There are some pressure sensors in the rockets that make the parts of the rocket release in each layer of space. Because of the oscillation in the engine, sinking bubbles effect on the sensors and made the rocket to release its parts sooner and this makes the rocket explodes. This phenomenon has been investigated in this research.

Salinity stress is one of the threats for plants in deserts and some parts of the world. Plants exposed to NaCl suffer from oxidative stress, and their growth disrupts through DNA damage and enzyme inactivation. It seems that exogenous antioxidants can increase plant tolerance to salinity. Therefore, the effect of fruits peel extract such as pomegranate, sweet lemon and pistachio as extracted antioxidants on improving germination and growth of susceptible seeds to salinity, such as beans, lettuce
and fennel were examined by using polar and semi-polar solvents, and ultrasonic bath and two positive (absence of sodium chloride and extracts) and negative (presence of sodium chloride and absence of the extracts) control groups.

In this project, the motor was built to create torque using the corona discharge phenomena. The DC excitation was replaced with electrostatic generators. Effect of some parameters (e.g. geometrical configurations and input voltage of the electrodes) were investigated. The fabrication was somehow done that with a fixed input voltage, the maximum rotation speed of 2150 rpm was attained

In this paper we will witness that by tying both ends of a string to unequal weights, lifting the end tied to the smaller weight with a specific angle would conclude in a small fraction of the string wrapping around the bar, thus stopping the larger weight from falling on the ground. On some conditions we observe that the light load spins around the rod because of the friction between rod and thread and prevent the heavy load from
hitting the floor.

When a number of Popsicle sticks are interlocked in each other, a mesh is produced, known as “The Cobra Wave”. As one of the sticks from the end
of the lattice is taken out, an explosion is happened and the wooden sticks
will be thrown consecutively, one after another. In this research this phenomenon was investigated and the affect the chain reactions was shown by using different sizes of popsicle.

When we tap a slinky spring we hear an amplified laser sound. Also after we tapped it we can see the slinky moving up and down. We use different
slinky springs with different lengths, diameter and we show that there is a
delay between higher frequencies and lower frequencies and it’s the reason for this laser shot sound. By decreasing the length this delay will decrease.
