It’s almost October and it’s time to celebrate science. Get ready for Earth Science Week this year (October 9–15, 2011). The theme is “Our Ever-Changing Earth.” You can move right into National Chemistry Week (October 16–22, 2011) The theme this year is “Chemistry—Our Health, Our Future.” Both of these websites have lots of resources, and it shouldn’t be hard to find some that align with your curriculum and standards.
Astronomy gets into the lineup of October events, too. Check out the Great World Wide Star Count in which your observation data can be uploaded and shared with participants from around the world during the October 14 — October 28 time period.
It’s not too early to plan events for Mole Day, celebrated on October 23 (10/23) from 6:02 a.m. to 6:02 p.m. The timing of this event celebrates Avogadro’s number: 6.02 · 10²³. See SciLinks for more information on  Avogadro: you’ll get a list of websites related to moles and to the work of this scientist. This day is also used to celebrate the science of chemistry and its applications. The National Mole Day Foundation’s website has background information, themes, and some suggested activities.
And then, top off the month by attending the NSTA conference in Hartford, CT from October 27 to October 29.
