Perhaps take the safe route and reduce carbon dioxide emissions?

Nice, but it's probably too late already.

The following is based on current estimates, subject to revision etc etc. A 2C average global temperature increase will lead to runaway warming due to permafrost melt and warmer oceans that absorb less CO2. Current emissions will lead to that value occurring around 2030.

To avoid that we would need to start cutting current global emissions by about 2%/year starting next year, down from +3% recent growth. That would make the warming curve top out at less than 2C.

There is no chance a US plan for such reduction will be put in place this year. Maybe by 2015 or so at which time the cuts would have to be more like 5 or 6%/year, down from 3% growth.

No economy can change it's mix of energy use by 9% net a year. So we are going to blow right by the runaway threshold, it's already done.

It sounds like CWIS may be what you're seeking. It's a free web-based turnkey package, developed at the University of Wisconsin - Madison and funded in part by NSF under the National Science Digital Library initiative. CWIS is written in PHP/MySQL, includes a search engine, a recommender engine, and a raft of other features, and is currently in use in a wide array of contexts.

Even with wind, ice and snow would make maintaining them a pain.

Yet switching is exactly what they're doing. (at least on the other pole) Getting diesel to remote locations is really expensive; it's already expensive enough to begin with compared to other sources of electricity.

Here's a webcam.

Some kids have problems with three dimensions, so the graphics capabilities can help to visualize molecular geometry and atomic or molecular orbitals. Electrostatic maps can help to show the polarity of molecules. Spreadsheets can be useful because of the ability to change parameters dynamically with the slider bars (note: it works for Excel as well as OpenOffice).

There are many apps at National Science Digital Library for K-12 classes. The main site is http://nsdl.org/ and the chemistry link is http://chemeddl.org/

The NIST Webbook (http://webbook.nist.gov/chemistry/) has a lot of reference data.

You could probably just do a web search on a particular topic and find several versions of java applets that people have come up with.
