gnomon : 100cm
shadow : 32,5cm
angle : 18Â°
We have decided to do the project on March 20th (Sunday). There are totally 20 students participating in the project, we have divided them into 4 groups. To know about the technical aspects of the project children spent an hour after the school hours from March 15 onwards.
By 11â€™o clock on the day of equinox, all the teams were ready with their measuring sticks in the ground. They measured the length of the shadow from 11:45 to 12:30 for every 10 minutes. They recorded shortest shadow at 12:20 PM (i.e, the local noon at Warangal). Then we sat down for calculating circumference. Using trigonometry they fond the angle of the sun, which equaled the angle at the center of the earth. The distance between warangal and equator was found to be 1998 KM, so 1998 * 20 (20 sectors) gave us the circumference.
We invited the Director of the planetarium and press to our school. The Director was with us till we calculated the circumference. He felt happy and thanked us for making him learn about Eratosthenes. All the local news papers and TV channels covered this news. We had lots of fun.
