Latitude:40.89 N Longitude: 74.58 W

The MacKinnon Middle School encompasses grades 6, 7 and 8. It is located in a small, suburban town near the north west of Morris County, New Jersey. The school is physically attached to two other constructions which house grades K through 5. This unique connection of multiple school buildings allows for sharing of support staff, library/tech lab, gymnasium and cafeteria. The newest construction completed in 2001, houses the Middle School population.

The students participating in this year’s Noon Day Project are all in Mrs. Allen and Mrs. Nichol’s Sixth Grade Sciences Classes. Mrs. Leary, the school’s technology and enrichment teacher, is conducting the Noon Day project with the students as an enrichment activity within their science classes. All of the students are preparing for this event by studying the website components and working through a detailed unit on the geometry behind the story. The students will also be involved with lessons highlighting the history of Eratosthenes and his great endeavor.

The MacKinnon sixth graders are excited to get started. They look forward to performing the measurements and calculating the Earth’s circumference during the week of Sept. 21st.

St Hilda's Anglican School for Girls, Mosman Park, Australia
Hi everybody

We are St Hilda's Anglican School for Girls Astronomical Society. Our school is located exactly on the southern 32nd parallel, which simplifies our calculations! We have approximately 1100 students and are very close to the Swan River in Mosman Park, which is a suburb of Perth, Western Australia. Our position is Latitude -32.00, Longitude 115.77.

Students from years 7 - 11 are in our Astronomical Society. We observe the sky as much as we can and we also love web projects such as this. Since our older students are very much occupied with exams at present, the Noonday project is to be set up and carried out by our Year 7 and 8 members.

Hoping for clear skies for everyone
St Monica School, Montreal, Quebec, Canada

Good Day! Bonjour!

Our school is an elementary school located on the island of Montreal, in the province of Québec, Canada with a total populaition of 165 students.

We are a bilingual school where French and English are taught at all levels, from Kindergarten to Grade 6. and where students from a specific grade alternate from English to French, one day to the other.

Our school promotes as extra-curricular activities team sports (soccer, basketball, etc), robotics and music. We have a steel pan band which performs many times in the year in front of the whole school as well as with other schools of our school board.

Our school was the host, last May, of the 8th annual Quebec Junior Robotic Contest, see the link :http://www.sciencetech.ca/now/index.php/v/junior_robotique_robotics/?option=com_g2bridge&view=gallery&Itemid=20&lang=fr

Our school participates in many different city basketball tournaments where our boy and girl teams often make it to the finals)

The class partiicipating in this year's Noon Day project is a Grade 6 science class with Monsieur Deschamps being the teacher.

Our school is located at 45.5 degree North and 73.75 degreee West.

We are part of the English Montreal school Board whose website is :

Wessington Springs Elementary School, Wessington Springs, South Dakota, USA
Greetings from the hills and prairie of central South Dakota. We are the 6th grade class from Wessington Springs, SD. We live in a small rural area with a population of about 1000. There are 298 students in our school K-12. Our latitude is 44.056011 and longitutde -98.56933593.
Our weather varies greatly. Our temperatures reach 100 degrees or more and dip down to 10 below or lower. We have quite a bit of wind which brings our wind chill factor down to sometimes 50 below.
The wind can be a blessing as it contributes to our wind turbine industry. In the past year we have constructed our first 31 wind turbines that line the hills above our town. Plans for more are in the near future with one being put up for our school.
Our area is known for hunting ring neck pheasants. There are numerous hunting lodges in our area which help to support our town. As mentioned earlier, we are a rural area so farming is a big part of our economy. We are a leader in club calf sales. We have buyers from across the United States that travel here to buy their show calves.
Our class looks forward to working with other schools.

To the participants of the Noonday Project,

We are a 10th grade class in Saint-Germain-en-Laye, which is a town located near both Paris and Versailles, France. Our town is the site of a royal palace that was used by many generations of French monarchs, including Louis XIV, who was born here. The latitude and longitude are 48°53'49"N and 2°5'29"E.
Our class is a special class called "seconde européenne". We study the same subjects as all other tenth-graders, but we also do something extra : part of our physics and chemistry curriculum is taught in English, and we also get extra English language classes in which the work we do is in some way related to physics and chemistry.
So we feel that the Noonday Project is just what we need to both practice and improve our English and learn about physics.
We are delighted to take part in a global project and look forward to working with other schools.
Rukmini Devi Public School, Delhi, India

Greetings to all !

We are grade 8 students from Rukmini Devi Public School, located in the capital city-Delhi of India (Latitude: 28.4° N and Longitude: 77.2° E). Our country portrays a landscape of vibrant cultural heritage and spiritual mysticism. Its rich customs and traditions bind its people together. So despite so much of diversity, we live side by side in harmony. We love to celebrate almost every occasion and are good host.

Final Report

We are grade 8 students from Rukmini Devi Public School, located in the capital city-Delhi of India (Latitude: 28.38° N and Longitude: 77.12° E) and doing this project as part of our subject “Collaborative Projects” in our school.

Firstly, our teacher explained us the set up and steps to measure the angle of the sun and circumference of the earth. We did our experiment on 25 September’ 2009 which was close to the Equinox day i.e 22 September’ 2009. Equinox is the time when the sun crosses the plane of the earth's equator, making night and day of approximately equal length all over the earth. We were fortunate to have sunny sky.

We were divided into groups of four to measure the angle of the sun. Out of 4 groups, we submitted the data, which was considered as best in comparison to the actual data. Here’s the procedure and measurements taken by that best group:

We started our experiment at 11.45 a.m. We took gnomon of length 19.5 cm and marked the shadow made by it after every 5 minutes of interval until the shadow started increasing. Then, we found the length of shortest shadow which came out to be 11.6 cm, which was cast by the gnomon at 12.15 p.m. Then by making right angle triangle between length of gnomon and shortest shadow of the gnomon, we measured the angle of the sun. The angle of the sun was measured to be 29°.

We took data from website of MacKinnon Middle School situated in NJ, U.S.A to calculate the circumference of the earth, which was done as follows:

Latitude of Delhi, India = 28.38° N
Angle of Sun measured = 29°

Latitude of Georgia, USA = 40.89° N
Angle of Sun measured = 41°

Central angle = 41° – 29° = 12°

Number of slices needed to make a full circle by central angle = 360 / 12 = 30.

The distance between these two places along a north-south line = 40.89°– 28.38° = 12.51°.

Now, as each angle of latitude = 111 km. Therefore, total distance between these two places along a North-South line = 12.51 x 111= 1388.61 km, which can be taken as 1388 km.

So if the length of the "slice" is about 1388 km and there are about 30 slices, then the projected circumference is 1388 x 30 = 41,640 km.

Therefore, the circumference of the earth came out to be 41,640 km, which is about 4% error, since the average circumference of earth is 40,008 km.

It was a real fun and enriching experience to measure the circumference of the earth using a method that was first used by Eratosthenes.

Through this project, we came to know that angle of sun we measured was equal to the latitude of our place. As a further enhancement to the project, when we will take up this project next time, we would also find longitude by shadow measurements.

Here is the link to the photographs of experiment:


We certainly look forward to work on it in future.
