Spring, 2006 Noon Day Project
Kickoff Message
See Latest data
See Updated Final Reports

Over 2200 years ago Eratosthenes, the chief librarian in Alexandria, Egypt made a remarkably accurate measurement of the earth's north-south circumference.

This project offers teachers and students an opportunity to recreate his amazing experiment by collaborating with teachers and students from other schools throughout the world. Students will at roughly the same time:

  • measure the length of a shadow cast by a stick a meter long.
  • share this data electronically.
  • use scale drawings and a spreadsheet to make comparisons.
  • use this information to estimate the circumference of the earth.
This activity is an opportunity for students to see how mathematics and science work together in explaining a real world phenomenon.

This project is recommended for upper elementary, middle school and high school students (ages 11-18). There is NO fee to participate. However we do ask you to register first.

Register for Project starting in September, 2006 -
coming in August.

If you have any questions please send an email to your project leader.
