A fun-filled hands-on science project outdoors, measure sun shadows and find the circumference of the Earth accurately! Replicate what Eratosthenes, an ancient Greek astronomer did 3000 years ago.
‘Project Paridhi’ is a flagship project of SPACE, to popularize hands-on science, students find out the circumference of the Earth by taking measurements of the shadows made by the sun in a day, as done 3000 years ago by astronomer Eratosthenes, who was able to measure it within 2% of the presently accepted value. This project was initiated 9 years ago in 2010 with the intention to increase awareness amongst Indians that science can be done without any complicated equipment.
It is a platform that proves science can be best learned by an experiment. It is open to all age groups and the public. It is typically conducted on days of Equinoxes and Solstices. ‘Project Paridhi’ is a scientific experimental project by SPACE to popularize hands-on science.
Description of ActivityThis is a hands-on science activity that involves measuring the length of shadows casted by a vertical object (gnomon) by the sunlight to determine the local noon. Simple trigonometry leads to the calculation of the circumference using the measured sun angle. This activity replicates the same activity which was done by Eratosthenes long ago.
Learning Outcomes and Benefits to SchoolsParticipants learn basic concepts of science in a fun way with hands-on science and use geometry and trigonometry. Some are trained as Earth Scientists and they can conduct the training for the others, which hones a leadership skill. Schools can host this project in their neighborhood to promote the experiment.

SPACE conducted project paridhi for the students of Sarvodaya kanya Vidyalaya,pushpvihar

2016
SPACE conducted Project Paridhi for students and the public on Winter Solstice at Qutub Minar
March'14
SPACE celebrated the first day of spring with its associated schools at JantarMantar by measuring the Earth
June'14
SPACE conducted Project Paridhi for students and the public on the Summer Solstice at India Gate.
This project involves the reading of shadows casted by a gnomon at the local noon. This can be done by different teams at one or more locations which have the same longitudes on the Globe.
For example, cities like New Delhi, Bangalore and Alma-ta in Kazakhstan fall almost at one degree of longitude and readings are taken at the same time from these cities which can tell us about the size and shape of the Earth. This experiment can be performed on any day but the conduction on the specific days of SOLSTICE AND EQUINOX is preferred, as the position of the sun on these days is directly overhead the Tropics of Capricorn or Tropics of Cancer or the Equator, makes the sun’s angle equal to or directly related to the latitude of the location. This makes the experiment easier to conduct and also helps in understanding the solstice and equinox.

Eratosthenes and the Experiment
2015 | ||
Special teams of students were nominated from 15 different schools. These students were trained in the conduction of Project Paridhi and its technical aspects. These students will further conduct this activity in their schools to enable the maximum awareness in the students by encouraging them to participate in the activity. These trained students will form a ‘Student Earth Scientists’ team who will accompany SPACE for the conduction, and further will volunteer to assist the conductions for the students who did not qualify in the experiment. |
