Science Experiments by Tamoghna Mookherjee,Piyush Jain And ATRI DATTA

ACTIVITY 1- CONSTRUCTION OF WIND-VANE

NAME- TAMOGHNA MOOKHERJEE
CLASS XISC A
PURPOSE OF MODEL- TO DETERMINE THE DIRECTION OF WIND.
A wind vane is an instrument used to show the direction, the wind is blowing from. It is one of the simplest weather instruments created and it has been used since ancient times.

ACTIVITY 2- CONSTRUCTION OF HOLOGRAM PROJECTOR

NAME- PIYUSH JAIN
CLASS XI SC C
PURPOSE OF MODEL- TO CREATE 3 DIMENSIONAL IMAGES BY THE PHENOMENON OF REFRACTION OF LIGHT.
HOLOGRAPHIC PROJECTORS USE HOLOGRAMS RATHER THAN GRAPHIC IMAGES TO PRODUCE PROJECTED PICTURES. IT SHINES SPECIAL WHITE LIGHT OR LASER BEAM ONTO OR THROUGH HOLOGRAMS. THE PROJECTED LIGHT PRODUCES BRIGHT 2D OR 3D IMAGES.

ACTIVITY 3- CONSTRUCTION OF HYDRAULIC ROBOTIC ARM

NAME- ATRI DATTA
CLASS XII SC B
PURPOSE OF MODEL- TO USE THIS MODEL AS AN ARTIFICIAL ARM FOR THE DISABLED PEOPLE.
It operates using syringe pistons and water pressure, thus utilising the concept of Pascal’s law of fluid pressure. This device can be modified more by using a motor system and voice controlled app which can then be used as an artificial arm for the disabled people whose arms may have been disabled.
