The Goal of the Noon Day Project is to have students measure the circumference of the earth using a method that was first used by Eratosthenes over 2000 years ago. Students at various sites around the world will measure shadows cast by a meter stick and compare their results. From this data students will be able to calculate the circumference of the earth.
|Doing the measurements|
- There is some good background material on the measurement at the Noon Day project site hosted by my friends at CIESE (Center for Innovation in Engineering & Science Education) - Stevens Institute of Technology in Hoboken, NJ
- Follow me on Twitter (Hashtag #noondaymeasure) as I recreate the experiment that Eratosthenes did. I plan to do my measurements this week.
- Also another great resource is provided by a European Astronomy group. Well worth a visit.
It will be done again in September, 2012. Let me know if you want a "heads up" early next year.
