How Stuff Works I wonder if this web site would be good for the curious student ?
Oxfam say that if you give a starving man a fish you feed his family for a day. If you teach a starving man how to fish you feed his family for a life time.

I used to have a deaf student who could lip read in English and Cantonese, I found it all a bit mind boggling. Sometimes she did not know what a word meant, she made the mistake of asking me what a word meant, I would not answer her but I would pass her the keyboard and direct her to OneLook.com. I helped her to help herself.
