The change in local time of every country with reference to the latitude of that country is explained here.

Description: Enjoy funny images given by the property of reflection at concave, convex and plane mirrors.

The inverted image gives us a straight idea about light rays property when it is allowed through a pinhole. Enjoy the scenery by rotating the camera all around.

The newton’s ring can be created with the set up here. The clear fringes teach us refraction, interference and diffraction of waves

A sundial is a device that determines the time of day by the position of the Sun. In common designs such as the horizontal sundial, the sun casts a shadow from its style onto a surface marked with lines indicating the hours of the day.

A windsock is a conical textile tube designed to indicate wind direction and relative wind speed. Wind direction is the opposite of the direction in which the windsock is pointing.

Description: Persistence of vision is the phenomenon of the eye by which an afterimage is thought to persist for approximately one twenty-fifth of a second on the retina. This property of retina is utilized in making motion picture. Here is a gadget that exhibits the concept of motion picture, where one side of the frame has a picture of a bird and other side has a bird cage, when this frame is rotated in high speed, we will visualize a picture as if the bird is inside the cage.

Description: A Newton disc is a disc with segments in rainbow colors. When the disc is rotated, the colors fade to white; In this way, Isaac Newton demonstrated that white light is a combination of the seven different colors found in a rainbow. This instrument is such a kind of color disc, while rotating this, we can observe white color disc.

This instrument is designed in such a way that it has two cylinders top one - solid metal and the down one - hollow cylinder, first the top cylinder is lifted and left to fall freely, now our mind presume that the weight of next cylinder is also the same as first one hence it will apply equal amount of force to lift both the cylinders together, as the second cylinder is less in weight will get lifted every easily and quickly which is a classical example for perception.

Description: Sympathetic resonance or sympathetic vibration is a harmonic phenomenon wherein a formerly passive string or vibratory body responds to external vibrations to which it has a harmonic likeness. This principle is applied here where if one person swings in one seat, the other seat starts swinging automatically without any effort.

Description: Simple harmonic motion is a type of periodic motion where the restoring force is directly proportional to the displacement. It can serve as a mathematical model of a variety of motions, such as the oscillation of a spring.

Description: A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets. The children can enjoy and feel the power of magnet with this fun filled gadget.

The rain gauge is a meteorological instrument for determining the depth of precipitation (usually in mm) that occurs over a unit area (usually one metre squared) and thus measuring rainfall amount. One millimetre of measured precipitation is the equivalent of one litre of rainfall per metre squared.

A periscope is an instrument for observation from a concealed position. Here a merry go round is attached with a large periscope revolves to instruct us the reflection of light at the plane mirror.

Humidity measurement instruments usually rely on measurements of some other quantity such as temperature, pressure, mass or a mechanical or electrical change in a substance as moisture is absorbed. By calibration and calculation, these measured quantities can lead to a measurement of humidity.
