little_anarchist on "jQuery Plug-in not working in wordPress"

I am trying to use this jQuery plug-in on a wordPress site:

I have created a non-wordPress test page. The plug-in works fine on this test page:
http://www.webslingers.ca/wp-content/themes/spaceman/content-hover.html

When I try to use it within a wordPress page it doesn't work:
http://www.webslingers.ca/content-hover-test/

I have tried loading the scripts in a variety of different ways (in the footer, header, noConflict etc.) with no success. I see that there are other posts where users are having this difficulty with WordPress and JQuery. None of them have helped me so far. What am I doing wrong?
