Since most of us live in remote places, this might be fun. Even city dwellers might find it illuminating. IMO, all homeschoolers should do it.
I've participated for the last 4 years.

The 5^th Annual Globe at Night Campaign: 3-16 March 2010

*What:* The Globe at Night Campaign

*When:* 8pm to 10pm local time, March 3-16, 2010*
**Where: *Everywhere*
**Who:* You! (Everyone!)*
**How: *See http://www.globeatnight.org *

*Why:*

*With half of the world’s population now living in cities, many urban dwellers have never experienced the wonderment of pristinely dark skies and maybe never will. This loss, caused by light pollution, is a concern on many fronts: safety, energy conservation, cost, health and effects on wildlife, as well as our ability to view the stars. Even though light pollution is a serious and growing global concern, it is one of the easiest environmental problems you can address on local levels.*

Globe at Night is an annual 2-week campaign in March that helps to address the light pollution issue locally as well as globally. This year the campaign is March 3-16, 2010. You are invited along with everyone all over the world to record the brightness of your night sky by matching its appearance toward the constellation Orion with star maps of progressively fainter stars found at /http://www.globeatnight.org/observe_magnitude.html./ You then submit your measurements on-line at http://www.globeatnight.org/report.html with your date, time and location. A few weeks later, organizers release a map of light-pollution levels worldwide. Over the last four 2-week Globe at Night campaigns, volunteers from over 100 nations have contributed 35,000 measurements.

To learn the five easy steps to participate in the Globe at Night program, see the Globe at Night website at http://www.globeatnight.org/./ You can listen to our 10-minute audio podcast on light pollution and Globe at Night at http://365daysofastronomy.org/2010/02/03/february-3rd-the-globe-at-night-campaign-our-light-or-starlight/

For activities that have children explore what light pollution is, what its effects are on wildlife and how to prepare for participating in the Globe at Night campaign, see the new activities at _http://www.darkskiesawareness.org/DarkSkiesRangers_.

Monitoring our environment will allow us as citizen-scientists to identify and preserve the dark sky oases in cities and locate areas where light pollution is increasing. All it takes is a few minutes during the March 2010 campaign to measure sky brightness and contribute those observations on-line. Help us exceed the 15,000 observations contributed last year. Your measurements will make a world of difference.

"Nothing in this world can take the place of persistence. Talent will not; nothing
is more common than unsuccessful people with talent. Genius will not; unrewarded genius
is almost a proverb. Education will not; the world is full of educated derelicts.
Persistence and determination alone are omnipotent. The slogan 'press on' has solved
and always will solve the problems of the human race"

~ Calvin Coolidge
