PROJECT NAME: Sun-Dial
DESCRIPTION: Whats the time Mr. Sun? Sun-Dial
PRINCIPLE:
Sundials have been in use for thousands of years. Sundials were replaced by clocks.
A sundial is a device that can be used at day to tell the time by the position of the sun
in the sky. Sundial is part of time telling history. It has two parts, the flat surface called
a dial plate, which is marked with numbered lines on the dial plate called hour lines
which shows the hours of the day.
A part called a gnomon is which sticks up at an angle from the dial plate. With the
position of the sun changing, the gnomon’s shadow moves around the dial. Every hour
the shadow falls on a new hour line, (it will allow you to understand position of the
shadow at a particular time).
MATERIAL:
Fevicol MR, Rangeela Tempera Colours, Card Paper, Cardboard Circle, A Thick Straw,
Ruler, Pencil, Scissors, Compass, Colour Palette, Water Container.
METHOD:
• To make the dial plate, cut out a cardboard circle measuring 4” in radius and
another circle to mark the numbers of the clock measuring 6” in radius. Paint the dial
plate with a picture of the sun in the centre using Rangeela Tempera Colours -
Yellow, Orange, Sky Blue made by mixing Blue and White and Black, respectively.
Leave it to dry.
• Stick a thick straw at the centre of the sun using Fevicol MR. Mark the hour lines on
the dial plate using Rangeela Tempera Colour - Black.
• Keep your sundial out on the terrace or ground and observe the shadows made by
the straw (Gnomon) falling on the dial.
• The shadows of the different times can give you tentative timings, which later can
be marked by you by referring to the clock. The position of the shadows will change
according to the seasons.
FUN FACTS
The earliest known sundial was made by ancient Egyptians in about 3500 BC. The
sundial was a stick or a pillar that cast a shadow on the ground. Clocks replaced the
sundials in the 1300’s.
Using this sundial principle and technique, innovate and create newer ideas
to make your projects unique and individualistic to you, lend a personal
touch and make your 3D models.
