Answer :

Steps for making Sundial are

(i) Collect tools like a stick (2 feet long), pebbles and a wrist watch.


(ii) Find a suitable and sunny area to plant the stick and plat it there. If you are living in northern hemisphere then slightly slant the stick towards the north. If you are in southern hemisphere then slant the stick towards the south.


(iii) If you want to complete the sundial in a single day, begin in the morning after the sun has fully risen. Survey the stick at 7:00 a.m. As the sun shines down on it, the stick will cast a shadow. Use one of your pebbles to mark the place where the shadow falls on the ground.


(iv) Return at 8:00 a.m. and use another pebble to mark where the stick’s shadow falls on the ground. Do the same thing at 9:00 a.m., 10:00 a.m. and so on.


(v) Get back every hour and mark it with a pebble on the ground. Do this until there is no more sunlight left in the day. Your sundial will be complete at day’s end. As long as the sun is shining, you can use this simple device to tell what time of the day it is.
