We appreciate that some students also use the site, but we cannot provide answers to student questions. For more on our aims, see 'about the site'. pdboyer Sat, 30 Apr 2011 22:32:14 GMT http://www.bio.davidson.edu/courses/movies.html QT and Flash to illustrate Biological Processes pdboyer Sat, 27 Feb 2010 17:47:02 GMT http://news.bbc.co.uk/go/rss/-/2/hi/europe/7689789.stm pdboyer Sat, 25 Oct 2008 23:04:36 GMT http://science.nasa.gov/astrophysics/big-questions/how-do-planets-stars-galaxies-and-cosmic-structure-come-into-being/ How do planets, stars, galaxies and cosmic structure come into being? In order to understand how the Universe has changed from its initial simple state following the Big Bang (only cooling elementary particles like protons and electrons) into the magnificent Universe we see as we look at the night sky, we must understand how stars, galaxies and planets are formed. pdboyer Sat, 06 Nov 2010 19:37:04 GMT http://www.scientificamerican.com/article.cfm?id=interactive-how-much-is-left Scientific American feature (interactive) about the planet's natural resources and how much of various things remain for our use. pdboyer Sat, 01 Jan 2011 04:13:51 GMT http://www.suite101.com/reference/how_to_deal_with_gang_problems Differences in Male and Female Gangs; Confronting Street Gangs in Canada; New Face of Organized Crime; Children in Gangs; Cannabis Farms; The Threat of Gangs to Rural Teenagers; Street Gangs; What are Gangs?; Preventing Youth Violence; U.S. Foreign Policy Blowback pdboyer Wed, 28 Jul 2010 13:02:57 GMT http://www.edutopia.org/free-school-supplies-fundraising-donation Resources for getting free stuff for the classroom.

A battery is essentially a can full of chemicals that produce electrons. Chemical reactions that produce electrons are called electrochemical reactions. In this article, you'll learn all about batteries -- the basic concept at work, the actual chemistry going on inside a battery, rechargeable versions, what the future holds for batteries and possible power sources that could replace them. pdboyer Sun, 10 Oct 2010 17:55:27 GMT http://spaceyourface.nasa.gov pdboyer Mon, 27 Jul 2009 03:55:26 GMT
