Purpose:     To find the density of  natural satellites when they are guessed to be composed of water (H20) and water ice. 
Web sites to be used:

Also see the notes from the water workshop by Leslie Lowes and Ron Ritschard.

Using reference materials (I would use the materials from this conference and materials like those found at the Nine Planets website:

This isn't water, but sunlight on our Moon, as seen through lunar phases:
   http://www.calvin.edu/~lmolnar/moon/
In particular, if your browser can handle Java, go to the "Tool and Quiz" - and turn the "person" by clicking the rounded arrows.  (I mentioned this in the Elementary Sci/Math discussion.)  Also check "phases of the moon"
   http://lunar.arc.nasa.gov/science/exp2.html
and the "ice on the moon" link from there.  The ultimate lunar phase information comes from the Naval Observatory:
   http://tycho.usno.navy.mil/vphase.html
It's one of the few places where the phases are correct relative to the dark maria (the "face" or "rabbit" in the moon).  Anything to do with time, the Naval Observatory is probably the authority - such as sun/moon rise/set times:
   http://tycho.usno.navy.mil/srss.html 

Or, see the "Earth and Moon viewer" (shows day and night sides):
   http://www.fourmilab.to/earthview/
You can also get software from this site. (Sunclock/geoclock, sky program, moon viewer.) 

In a similar way, you can get a diagram of our Solar System for any date & time from:
   http://www.fourmilab.to/solar/
Or a more detailed view from:
   http://space.jpl.nasa.gov/ 

   http://cse.ssl.berkeley.edu/segway/
contains lessons called "Ice on Venus?"  and "Search for Ice and Snow" - both are based on images from space. 

There are tools to look at the surface temperature of a world and how it varies with things like atmosphere, greenhouse gases, and clouds:

Since water vapor is a greenhouse gas, and clouds on Mars and Venus as well as Earth also depend on water, this seemed relevant to me.

There is an interesting article in American Scientist (Volume 87 or Nov.-Dec 99), regarding the discovery of a lake under the Antarctic ice sheet, Lake Vostok, the largest subglacial lake in the world. Scientists expect to find microorganisms in the lake. You can find an internet link at

There are teachers now in the Dry Valleys of Antarctica working with researchers.  I do not know if they are at the lake that you mention above but they can be reached and email from them will be sent to your classroom if you have questions.
