Annual Meeting in Denver Technology Sessions Update

through March 22
I've updated the listing of technology sessions at the Denver Annual NCTM meeting including more details about the sessions from the speakers who have responded to my request which is if you are a speaker on a technolgy theme and your session is not listed please let me know ( and I will include your session. If it is listed and you wish to have more detail than what is currently there please send me a photo along with any additional information about your session. We know that you submitted your proposal to speak last May and you may want your potential attendees to know more about you and your presentation. I'll be continuing to update this listing (here is the link again) right through the conference. So its never to late to do so.

I will be attending the conference though this year CLIME will not be exhibiting so I'll be free to roam and report back to you about the sessions and exhibits that I found interesting.

I hope to see you there.

Noon Day project measurements begin this week- March 18, 2013

Carl Sagan tells the story (6.5min)
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
You can sign up for this project here.
  • 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.
